IC50 = 2580 nM, ratio = 21). The methyleneamino and hydroxyethylene replacements, which have been used elsewhere as transition-state inhibitors of enzymes, are poor mimics of the amide in these CCK-B receptor ligands. Some of the steric, lipophilic, and hydrogen bonding properties of amide replacements incorporated into the simple amide, N-methylacetamide, have been quantified with the aid of molecular
本文描述了一系列化合物的化学合成以及CCK-B和CCK-A受体的结合亲和力,其中CCK-B“二肽”配体三环[3.3.1.1(3,7)] dec- 2-基[R-(R *,S *)]-[2-[[1-(羟甲基)-2-苯乙基]氨基] -1-(1H-吲哚-3-基甲基)-2-氧代乙基] carb酸酯(4)(CCK-B IC50 = 852 nM)和三环[3.3.1.1(3,7)] dec-2-基(R)-[1-(1H-吲哚-3-基甲基)-1-甲基-2-氧代-2-[[(2-苯基乙基)氨基]乙基]氨基甲酸酯(23)(CCK-B IC50 = 32 nM)被11种不同的酰胺替代物取代。这些替代物是亚甲基氨基(CH2NH),反向酰胺(NHCO),酯(COO),N-甲基酰胺(CONMe),硫代酰胺(CSNH),N-乙酰基亚甲基氨基(CH2NAc),顺式双键(CHCH) ),乙烯(CH2CH2),硫醇酯(COS),羟基乙烯(CHOHCH2)和4
