The development of dual inhibitors of the two zinc metallopeptidases, neprilysin (neutral endopeptidase) and aminopeptidase N involved in the inactivation of the opioid peptides, enkephalins, represents an attractive physiological approach in the search for new analgesics devoid of the major drawbacks of morphine. Phosphinic compounds, corresponding to the general formula H(3)N(+)-CH(R(1))-P(O)(OH
涉及阿片类肽脑啡肽失活的两种锌金属肽酶,中性溶酶(中性内肽酶)和氨基肽酶N双重抑制剂的开发代表了一种寻找新的止痛药的有吸引力的生理方法,该止痛药没有吗啡的主要缺点。对应于通式H(3)N(+)-CH(R(1))-P(O)(OH)-CH(2)-CH(R(2))-CONH-CH( R(3))-COO(-),能够充当过渡态类似物并适合两种酶的S(1),S(1)'和S(2)'亚位点。选择R(1),R(2)和R(3)残基以最佳识别这些酶,导致了首个双重竞争抑制剂,其脑啡肽酶和氨基肽酶N的K(i)值在纳摩尔范围内。
