非肽类sst 2激动剂可为肢端肥大症、类癌和神经内分泌肿瘤患者提供新的治疗选择。我们在药物化学方面的努力已经发现了作为SST 2激动剂的新型3,4-二氢喹唑啉-4-甲酰胺。这类分子对sst 1、sst 3、sst 4和sst 5受体表现出优异的人sst 2效力和选择性。先导化合物3-(3-氯-5-甲基苯基)-6-(3-氟-2-羟基苯基)-N,7-二甲基-N-{[(2S)-吡咯烷-2-基]甲基}-3,4-二氢喹唑啉-4-甲酰胺(28)对主要CYP 450酶(2C 9、2C 19、2D 6和3A 4)无抑制作用,对hERG通道的抑制作用较弱。
Nonpeptide sst2 agonists can provide a new treatment option for patients with acromegaly, carcinoid tumors, and neuroendocrine tumors. Our medicinal chemistry efforts have led to the discovery of novel 3,4-dihydroquinazoline-4-carboxamides as sst2 agonists. This class of molecules exhibits excellent human sst2 potency and selectivity against sst1, sst3, sst4 and sst5 receptors. Leading compound 3-(3-chloro-5-methylphenyl)-6-(3-fluoro-2-hydroxyphenyl)-N,7-dimethyl-N-{[(2S)-pyrrolidin-2-yl]methyl}-3,4-dihydroquinazoline-4-carboxamide (28) showed no inhibition of major CYP450 enzymes (2C9, 2C19, 2D6 and 3A4) and weak inhibition of the hERG channel.
