showed that there should be the optimal size among the various N-alkyl chains. Also a significant increase in the receptor binding affinity was achieved by several compounds. Among those compounds, 2-[3-[3- [N-cyclohexylmethyl-N-[2-(N-methyl- N-phenylcarbamoylmethoxy)phenyl]carbamoylmethyl]ureido]pheny l]acetic acid (22c) and (+/-)-2-[3-[3-[N-[2-(N-methyl-N- phenylcarbamoylmethoxy)phenyl]-N-(3-methylpentyl)carbamoy
为了改善DA-3934(5)的生物学特性,已合成了一种新型胃泌素/胆囊收缩素(CCK)-B受体拮抗剂,苯氧乙酸衍生物用各种烷基链取代了5的N-甲基-N-苯基氨基甲酰基甲基部分并评估其生物学活性。这些化合物的结构与其人胃泌素受体结合亲和力之间的关系表明,各种N-烷基链之间应有最佳大小。还通过几种化合物实现了受体结合亲和力的显着增加。在这些化合物中,
