Amine-aldehyde resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These resins are especially useful as froth flotation depressants, for example in the beneficiation of value materials (e.g., bitumen, coal, or kaolin clay) to remove impurities such as sand. The resins are also useful for treating aqueous liquid suspensions to remove solid particulates, as well as for removing metallic ions in the purification of water. |

The present invention relates to an IgG-binding compound, which more specifically has affinity for human IgGs of κ-type and functional derivatives thereof. More specifically, the compound according to the invention comprises an N,N-alkylated urea moiety located between an aromatic part and another part, which is a linear or cyclic substituted or unsubstituted aliphatic group. The compound binds to a pocket-shaped binding site present on all human IgG κ-Fabs, which site is located between the two domains (CH1 and CL) of its constant part. Accordingly, the compound according to the invention is a ligand for human IgGs of κ-type, and consequently, the invention also relates to a separation matrix for affinity chromatography, which matrix comprises said compound, as well as to other uses of the compound. |

The present invention relates to achiral polyurea oligomers, their uses and formulations as anti-HIV pharmaceuticals and to a process for the preparation of narrow mono- and polydispersed oligomers as an emodiment of the invention. The achiral oligomers are derived from repeating units of the monomer 4,4'-diamino-biphenyl-3,3'-disulfonic acid and are water soluble, have a rigid backbone, possess ordered anionic spacing and have a number average molecular weight of <20,000. The process relates to the synthesis of narrow poly- and mono-dipersed oligomers comprising the steps of: 1) restricting the crude olydispersed anionic oligomer mixture to a narrow polydispersed anionic oligomer mixture to a narrow polydispersed anionic oligomer mixture; and/or 2) isolating the monodispersed anionic oligomer; and 3) optionally converting the narrow poly- or mono-dispersed anionic oligomer salt from Step 1 or 2 to a desired pharmaceutically-acceptable salt, especially a solim or potassium salt. The process steps may be executed whereby step 1 or 2 is done alone, each in combination with Step 3, or all three steps are done. |
