A series of 2-pyridone-containing imidazoline derivatives was synthesized and evaluated as neuropeptide Y Y5 receptor antagonists. Optimization of the 2-pyridone structure on the 2-position of the imidazoline ring led to identification of 1-(difluoromethyl)-5-[(4S,5S)-4-(4-fluorophenyl)-4-(6-fluoropyridin-3-yl)-5-methyl-4,5-dihydro-1H-imidazol-2-yl]pyridin-2(1H)-one (7m, I). Compound 7m displayed statistically significant inhibition of food intake in an agonist-induced food intake model in SD rats and no adverse cardiovascular effects in anesthetized dogs. In addition, markedly higher brain penetrability and a lower plasma Occ90 value were observed in P-gp-deficient mdr1a (-/-) mice compared to mdr1a (+/+) mice after oral administration of 7m.

Author is Winterton, Sarah E.; Capota, Emanuela; Wang, Xiaoyu; Chen, Hong; Mallipeddi, Prema L.; Williams, Noelle S.; Posner, Bruce A.; Nijhawan, Deepak; Ready, Joseph M..

Stearoyl-CoA desaturase (SCD) catalyzes the first step in the conversion of saturated fatty acids to unsaturated fatty acids. Unsaturated fatty acids are required for membrane integrity and for cell proliferation. For these reasons, inhibitors of SCD represent potential treatments for cancer. However, systemically active SCD inhibitors result in skin toxicity, which presents an obstacle to their development. We recently described a series of oxalic acid diamides that are converted into active SCD inhibitors within a subset of cancers by CYP4F11-mediated metabolism Herein, we describe the optimization of the oxalic acid diamides and related N-acyl ureas and an anal. of the structure-activity relationships related to metabolic activation and SCD inhibition.

Author is Hu, Jing; Wu, Tian-Ming; Li, Hong-Ze; Zuo, Ze-Ping; Zhao, Ying-Lan; Yang, Li.

Cisplatin is a widely used antineoplastic drug, while its nephrotoxicity limits the clin. application. Although several mechanisms contributing to nephrotoxicity are reported, the direct protein targets are unclear. Herein the authors reported the synthesis of 29 cisplatin derivatives and the structure-toxicity relation (STR) of these compounds with MTT assay in human renal proximal tubule cells (HK-2) and pig kidney epithelial cells (LLC-PK1). To the best of the authors’ knowledge, this study represented the 1st report regarding the structure-toxicity relation (STR) of cisplatin derivatives The potency of biotin-pyridine conjugated derivative 3 met the requirement for target identification, and the preliminary chem. proteomics results suggested that it is a promising tool for further target identification of cisplatin-induced nephrotoxicity.
