The novel compounds of this invention may be synthesized according to the novel cyclizing reaction as illustrated schematically below: ##STR6## wherein X is sulfur or oxygen indicating that the reaction can employ as starting material either an amidinourea or amidinothiourea. The dangling bonds may be substituted by any appropriate substituent determined by available amidinourea or amidinothiourea starting material. The dangling bonds on the end product 1,3,5-triazin-2-one or 1,3,5-triazine-2-thione, will be substituted by groups corresponding to similar substituents on the starting materials.
It has been found that an amidinourea can be cyclized to the corresponding s-triazinone by condensing the amidinourea with an organic reagent having an activated methylidene group or capable of forming an activated methylidene, for example, a methylidene group having at least one available hydrogen atom and a leaving group such as a di-substituted amino group attached to the methylidene carbon. The organic reagent used for condensing the amidinourea starting material to form the corresponding s-triazinone may be an activated form of an acid amide, an ortho ester or acyl derivative, such as, a Vilsmeir reagent which will bring about acylation and ring closure of the amidinourea or thiourea to give s-triazinones of Formula I above. The cyclizing process can be used in the same manner to prepare s-triazinthiones from the corresponding amidinothioureas and it will be understood that in referring to the preparation of triazinones it is intended to include also the thiones. The reagent may be the dialkylacetal of a di-alkyl-lower carboxylic acid amide or the reaction product of a di-alkyllower carboxylic acid amide and an alkylating agent. The reagent can be prepared in situ or in advance depending upon its stability. The synthesis of triazinones according to this invention can employ as starting material known amidinoureas or similar starting materials also known in the art, or the materials employed as precursors for cyclizing to form s-triazinones can be readily prepared by analogy to the preparation of the known starting materials. Suitable amidinourea starting materials are those disclosed in copending U.S. patent application Ser. No. 262,808, U.S. Pat. Nos. 4,060,635; 4,058,557; and 4,178,387, the disclosures of which are incorporated herein by reference.

By way of illustration, an alternative structure is shown by Formula II-a. Where reference is made to the terminal nitrogens, it is intended to denote the urea nitrogen designated as position 1 in Formula II and the unsubstituted amidino nitrogen.

1-aryl-1,2-dihydro-s-triazine derivatives are known to possess a broad spectrum of biological activity (heterocyclic Compounds, Vol. 7, John Wiley & Sons, Inc., 1961, p. 717-18). The novel compounds of this invention constitute a new class of 1-aralkyl-1,2-dihydro-2-triazines, particularly 1-heterocyclic alkylene-1,2-dihydro-1,3,5-triazin-2-ones which similarly have a broad spectrum of biological activity. Thus, these compounds possess useful gastrointestinal actions and can be used for example as antidiarrheal agents for the treatment of gastrointestinal disorders. Whereas amidinoureas also have local anesthetic and other pharmacological effects when administered at dose levels for effective antidiarrheal action, certain of the novel triazinones possess good antidiarrheal activity without local anesthetic or other side effects at active dose levels. Certain of the novel triazine derivatives possess other gastrogenic and related effects, particularly antisecretory action, making them useful in the treatment of such gastrointestinal disorders as peptic ulcers. Compounds of this series also possess anti-motility and spasmolytic effects making them useful in the control of muscle spasm particularly stomach or intestinal spasms. Certain of the compounds also exhibit novel effects on nerve impulse transmissions wherein multiple high frequency nerve transmissions are blocked.
The amidinoureas from which the novel triazine derivatives are prepared according to this invention possess useful pharmacological properties including antidiarrheal activity in mammalian species. Generally, it has been found that the antidiarrheal properties of the amidinourea are not lost in cyclizing to the corresponding triazine derivative. Accordingly, the novel triazine derivatives of this invention are also useful antidiarrheal agents as shown by test results in animals, which, based on previous experience with the corresponding amidinoureas, show good correlation to activity in humans.
Various tests can be carried out in animal models to show the ability of the heterocyclic alkylene triazinones of this invention to exhibit reactions that can be correlated with anti-diarrheal activity in humans. The following tests show the ability of the compounds of this invention to inhibit diarrhea in animals and are known to correlate well with antidiarrheal activity in humans. These are considered to be standard tests used to determine antidiarrheal properties. This correlation can be shown by the activities of compounds known to be clinically active.
The test compound is dissolved in distilled water, unless otherwise stated. The ED50 values and 95% confidence limits are calculated according to a method described by D. F. Finney (Probit Analysis, 2nd Ed., University Press, Cambridge, p. 236, 1964).
1. Antagonism of Castor Oil-induced Diarrhea in Mice
A modified test described by Niemegeers et al. (Arzneim-Forscth 22, 516-518, 1972) was used. Groups of ten male Swiss Webster mice (22-25 g) were randomly selected for dosing. Castor oil (Fischer Scientific Co.), 0.3 ml/mouse, was given orally one hour after an oral dose of test compound or the vehicle. After dosing with castor oil, each mouse was placed into an individual wire cage and observed for six hours for diarrhea.
2. Antagonism of Castor Oil-induced Diarrhea in Rats
A test described by Niemegeers et al. (supra) was used. Groups of ten female Wistar rats (180-200 g) were randomly selected for dosing. In addition, groups of ten female Sprague-Dawly rats (180-200 g) were used to determine strain difference. Castor oil (Fisher Scientific Co.), 1 ml/rat, was given orally one hour after an oral dose of test compound or the vehicle. After dosing with castor oil, each rat was placed into an individual wire cage and observed for six hours for diarrhea.
3. Antagonism of Chemically-induced Diarrhea in Mice
Male Swiss Webster mice (18-22 g) in groups of 10-20 mice were randomly selected for oral dosing with test compound or the vehicle one hour before the intraperitoneal injection of either 400 μg/kg of Carbachol (carbamycholine chloride, Sigma Chemical Co., St. Louis, Missouri); or, 200 μg/kg of serotonin creatinine sulfate (Schwartz/Mann Biochemicals, Orangeburg, New York). After each mouse was injected, it was placed into an individual wire cage and observed for diarrhea.
4. Inhibition of the Gastrointestinal Transit Time of a Charcoal Meal in Mice
A charcoal suspension (10 ml/kg of a 10% suspension) was given orally to groups of ten Swiss Webster male mice (18-22 g) one hour after an oral dose of test compound or vehicle. The mice were sacrificed by cervical dislocation 30 minutes after the charcoal meal and the distance in millimeters that the charcoal meal traveled through the small intestine was measured and compared to the controls. ##EQU1##
5. The Effect of Naloxone on the Inhibitory Actions of Triazinones on Gastrointestinal Motility
Male Swiss Webster mice (18-20 g) in groups of ten were randomly selected for dosing with test compound or the vehicle alone and concomitantly with naloxone. The naloxone was dissolved in saline.
The mice were given a charcoal meal (10 ml/kg of a 10% suspension) one hour after an oral dose of the vehicle or a test compound(s). Thirty minutes after the charcoal meal the mice were sacrificed by cervical dislocation and the distance in millimeters that the charcoal meal traveled through the small intestine was measured and compared to the controls.
6. Fecal Output Tolerance Study in Rats
Male Wistar rats (140-180 g) were given oral doses of either test compound, diphenoxylate HCl (suspended in methylcellulose or the vehicle (distilled water or methylcellulose) once a day for five consecutive days. Vehicle or the test compound were given daily 30 minutes before fecal collection. The feces were collected in a completely automated four-tiered metabolic cage over a 12-hour period consisting of three, four-hour intervals. Following collection, the feces were dried for four hours at 200° C. and weighed.
7. Prostaglandin test
An intraperitoneal injection of 100 micrograms per kilogram of PGE2 causes diarrhea in mice within ten minutes. Groups of mice were orally dosed with test compound at various dose levels after which the PGE2 is given and ten minutes later the mice are checked for diarrhea to determine the ED50.
The amidinourea starting materials, in addition to having antidiarrheal properties, possess other pharmacological activities such as local anesthetic and cardiovascular activity. Unlike the amidinoureas which generally have local anesthetic properties, the pharmaceutically useful 1-heterocyclic alkylene-1,2-dihydro-1,3,5-triazin-2-ones and thiones of this invention are more specific and possess little or no classical local anesthetic effects, nor do they possess significant cardiovascular effects. The compounds of Formula I are particularly useful as antidiarrheal agents where it is desirable to achieve an antidiarrheal effect with a minimum of side effects and these compounds are therefore especially suited to the treatment of gastrogenic diarrhea.
The tests employed to determine the separation of local anesthetic and cardiovascular activity at effective antidiarrheal doses with representative compounds of the formula above are described below.
Several different procedures generally employed in testing for local anesthetic activity ar used to determine local anesthetic effects. These tests have been used extensively in the past and have given satisfactory results in defining the local anesthetic properties of compounds.
A discussion of experimental methods for evaluating local anesthetic properties of drugs is found in Evaluation of Drug Activities: Pharmacometrics, Vol. 1, Ed by D. R. Lawrence and A. L. Bacharach, Academic Press, Inc. (London) Ltd. (1964). Applicants herewith incorporate by reference Chapter 9 of this book entitled "Local Anesthetics", pages 204-214.
Tests which show the lack of side effects of the preferred amidinourea compounds include the following:

The test compound and a vehicle given orally thirty minutes before hexobarbital were compared for their effect on the duration of the loss of righting reflex (failure to right within five seconds) induced in groups of Swiss Webster mice (10/group, 18-20 g) by the intraperitoneal injection of hexobarbital (100 mg/kg, l.P.).
2. Effect of Plasma Glucose in Rats
Groups of 5-10 male Sprague-Dawley rats (170-210 g) were orally dosed with the test compound or the vehicle. Three hours after dosing, the rats were sacrificed by decapitation and blood was collected for plasma glucose evaluation.
3. Effect of Inducing Emesis in Dogs
Female beagle dogs (6-10 kg) were randomly selected for intravenous dosing with the test compound. Each dose of the test compounds was given to either two or four dogs. Immediately after the injection, the dogs were observed for emesis for a period of up to one hour.
Certain of the compounds possess differentiated levels of effectiveness as antisecretory or antimotility agents when administered in generally used tests in laboratory animals which tests are known to correlate to human application. The following test is utilized in establishing the antisecretory activity of the triazine derivatives.
Inhibition of Gastric Acid Secretion in the Rat
The method used has been reported by Shay. Male Sprague-Dawley rats (140-160 g) were fasted 24 hours prior to the test. The rats were allowed water ad libitum only during the fasting period. One hour before pyloric ligation, the rats (5/group) were given either the test compound, atropine sulfate or the vehicle. The compounds were prepared in methylcellulose. Pyloric ligation was performed in the rats under sodium methohexital anesthesia. Four hours after pyloric ligation the rats were sacrificed by cervical dislocation, the stomachs were removed, and the gastric contents were assayed for volume, titratable acidity, and titratable acid output (TAO). A 1 ml aliquot of the gastric contents was titrated with 0.1 N NaOH to pH 7.0 for titratable acidity. The percent of inhibition was calculated according to the formula: ##EQU2##
In general, compounds of Formula I are indicated for use as pharmacotherapeutic agent in a wide variety of mammalian conditions which require relief of symptoms or altering the action of the gastrointestinal or neuro-muscular systems. These compounds when used for example, as antidiarrheal, antisecretory or antispasmodic agents, are effective for these purposes when administered orally and/or parenterally. The term "parenteral" as used herein includes intravenous, intramuscular, intraperatoneal and the like injection or infusion techniques.
The dosage regimens in carrying out the pharmacotherapeutic methods utilizing the triazin-2-ones and triazin-2-thiones of this invention are those which insure maximum therapeutic response until improvement is obtained and thereafter the minimum effective level which gives relief. Thus, in general, the dosages are those that are therapeutically effective in the treatment of diarrhea and related gastrointestinal disorders. In general, the oral daily dose can be between about 0.1 mg/kg and 70 mg/kg (preferably in the range of 0.5-50 mg/kg/day), bearing in mind, of course, that in selecting the appropriate dosage in any specific case, consideration must be given to the patient's weight, general health, age, and other factors which may influence response to the drug.
Compositions intended for oral use may be prepared according to any method known to the art for the manufacture of pharmaceutical compositions and such compositions may contain one or more agents selected from the group consisting of sweetening agents, flavoring agents, coloring agents and preserving agents, in order to provide a pharmaceutically elegant and palatable preparation. Orally, they may be administered in tablets, aqueous or oily suspensions, dispersible powders or granules, emulsions, hard or soft capsules, or syrups or elixers. Tablets which contain the active ingredient in admixture with non-toxic pharmaceutically acceptable excipients are suitable for the manufacture of tablets. These excipients may be, for example, inert diluents, for example, calcium carbonate, sodium carbonate, lactose, calcium phosphate or sodium phosphate; granulating and disintegrating agents, for example, maize starch or alginic acid; binding agents, for example, starch, gelatin or acacia; and lubricating agents, for example, magnesium stearate, stearic acid or talc. The tablets may be uncoated or they may be coated by known techniques to delay disintegration and absorption.
Formulations for oral use may also be presented as hard gelatin capsules wherein the active ingredient is mixed with an inert solid diluent, for example, calcium carbonate, calcium phosphate or kaolin, or as soft gelatin capsules wherein the active ingredient is mixed with an oil medium, for example, arachis oil, liquid paraffin or olive oil.
Aqueous solutions containing the active substance and similar compositions formulated for ease of administration depending upon the particular therapeutic or prophylactic objective form a separate development with respect to the active compound disclosed herein. Excipients suitable for aqueous suspensions, may be employed if desired. These excipients are suspending agents, for example, sodium carboxymethyl-cellulose, methyl-cellulose, hydroxypropylmethylcellulose, sodium alginate, polyvinylpyrrolidine, gum tragacanth and gum acacia; dispersing or wetting agents may be a naturally occurring phosphatide, for example, lecithin; or condensation products of an alkylene oxide with fatty acids, for example, polyoxyethylene stearate; or condensation products of ethylene oxide with long-chain aliphatic alcohols, for example, heptadecaethyleneoxy-cetanol; or condensation products of ethylene oxide with partial esters derived from fatty acids and a hexitol, for example, polyoxyethylene sorbitol mono-oleate; or condensation products of ethylene oxide with partial esters derived from fatty acids and hexitol anhydrides, for example, polyoxyethylene sorbitan monoleate. The said aqueous suspensions may also contain one or more preservatives, for example, ethyl, or n-propyl, p-hydroxy benzoate, one or more coloring agents, one or more flavoring agents, and one or more sweetening agents, such as sucrose.
Oily suspensions may be formulated by suspending the active ingredient in a vegetable oil, for example, arachis oil, olive oil, sesame oil or coconut oil, or in a mineral oil, such as liquid paraffin. The oily suspensions may contain a thickening agent, for example, beeswax, hard paraffin or cetyl alcohol. Sweetening agents, such as those set forth above, and flavoring agents may be added to provide a palatable oral preparation. These compositions may be preserved by the addition of an anti-oxidant such as ascorbic acid.
Dispersible powders and granules suitable for preparation of an aqueous suspension by the addition of water provide the active ingredient in admixture with a dispersing or wetting agent, suspending or wetting agents and suspending agents are exemplified by those already mentioned above. Additional excipients, for example, sweetening, flavoring and coloring agents, may also be present.
The compounds of this invention may also be in the form of oil-in-water emulsions. The oily phase may be a vegetable oil, for example, olive oil or arachis oils, or a mineral oil, for example, liquid paraffin or mixtures of these. Suitable emulsifying agents may be naturally-occurring gums, for example, gum acacia or gum tragacanth, naturally-occurring phosphatides, for example, soya bean lecithin, and esters or partial esters derived from fatty acids and hexitol anhydrides, for example, sorbitan mono-oleage. The emulsions may also contain sweeping and flavoring agents.
Syrups and elixirs may be formulated with sweetening agents, for example, glycerol, sorbitol or sucrose. Such formulations may also contain a demulcent, a preservative and flavoring and coloring agents. The pharmaceutical compositions may be in the form of a sterile injectionable preparation, for example, as a sterile injectable aqueous suspension. This suspension may be formulated according to the known art using those suitable dispersing or wetting agents and suspending agents which have been mentioned above. The sterile injectable preparation may also be a sterile injectable solution or suspension in a nontoxic parenterally-acceptable diluent or solvent, for example, as an aqueous solution buffered to a pH of 4.0 to 7.0 and made isotonic with sodium chloride.
Further, the active triazine may be administered alone or in admixture with other agents having the same or different pharmacological properties.
Further, these compounds may be tableted or otherwise formulated for oral use so that for every 100 parts by weight of the composition, there are present between 5 and 95 parts by weight of the active ingredient. The dosage unit form will generally contain between about 1 mg. and about 500 mg. of the active ingredients of this invention. The preferred unit dose is between about 10 mg. and about 100 mg. The compositions may be taken 1-8 times daily depending on the dosage unit required.
Parenteral administration may be carried out using comparative dosages taken from the oral compositions. In general, the parenteral dosage will be less than the oral dose and normally within the range of 1/2 to 1/10 the oral dose but, of course, this would depend on the absorption characteristics of the compound employed. Dosages would be in the customary manner; however, in general, parenteral administration may be carried out neat or the compound may be utilized with a sterile vehicle as mentioned above. Dosage unit forms between 1 mg. and 500 mg. and preferably in the range of 10 mg. and 100 mg. are useful. The daily parenteral dose would be between 0.1 mg/Kg/day and 70 mg/Kg/day and preferably in the range of 0.5 mg/Kg and 50 mg/Kg/day.
The compounds of this invention are also useful as veterinary medicines. In particular, these compounds are useful in the treatment of animal scours, particularly in food animals. When administered in suitable formulations, for example, as additives to food or water, these compounds prevent or relieve scours in lambs, calves, piglets and fowl.
