Performance mapping of equipment performance parameters by capturing, mapping, and/or structuralizing equipment performance data of a device for installation in a system. This includes generating performance maps which outline the expected feature performance parameter behavior of the equipment based on a set of operating parameters that capture the operating conditions. Each performance parameter on the map is representative of an operating point of specific operating conditions taken at a particular point in time. In one example, a performance parameter can be defined by an individualized set of parameter coefficients which in turn are dependent on instantaneous operating conditions. With the performance maps determined individually for devices as part of the system, and stored along with a time of testing, activities such as continuous commissioning, monitoring and verification, preventative maintenance, fault detection and diagnostics, as well as energy performance benchmarking and long term monitoring can be performed. |

2-alkoxy-6-[18F]fluoronicotinoyl substituted lys-c(O)-glu derivatives as efficient probes for imaging of PSMA expressing tissues
6-[18F]Fluoro-2-alkoxynicotinoyl substituted Lys-C(O)-Glu derivatives were identified as efficient imaging probes for PSMA expressing tissues in comparison to other known PSMA specific ligands like [18F]DCFPyL, [68Ga]HBED-CC-PSMA, [18F]PSMA-1007 and [Al18F]HBED-CC-PSMA. Unexpectedly, the 6-[18F]fluoro-2-alkoxy and 6-[18F]fluoro-4-alkoxy substituted analogs showed significant differences in accumulation in PSMA expressing prostate tumor cells. Whereas the 2-alkoxy derivative showed cellular uptake values higher than [18F]DCFPyL, the cellular uptake of the corresponding 4-alkoxy substituted derivative was significantly lower. Furthermore, in vivo PET studies with 2-alkoxy-substituted probes demonstrated excellent visualization of PSMA positive ganglia with extremely high target to background ratio. In contrast, the 4-alkoxy substituted derivatives showed less favorable biodistribution with significantly lower uptake in PSMA positive tissues. Especially, the 18F-labeled 2-methoxy derivate ((2S)-2-({[(1S)-1-carboxy-5-[(6-[18F]fluoro-2-methoxypyridin-3-yl)formamido]pentyl]carbamoyl}-amino)pentanedioic acid) demonstrated exceptional clinical efficiency in detecting small PCa lesions, including those which could not be visualized with [68Ga]HBED-CC-PSMA representing currently the gold standard for the diagnosis of recurrent PCa. Furthermore, this probe is easily accessible on a preparative scale in commercially available automated synthesis modules like GE FASTlab and TRACERlab FX N Pro. Consequently, the novel probe is a valuable tool for the visualization of ganglia and reendothelialization as well as for the diagnosis of glioma, neuropathic pain and atherosclerotic plaques. |
