Seryl-lysyl-based peptide and peptidomimetic compounds are described as inhibitors of the enzyme N-myristoyl transferase to provide selective control of the fungal organism Candida albicans. Peptidomimetic compounds of particular interest are those of the formula: ##STR1## wherein R.sup.1 is selected form aminoalkyl, p-aminoalkylphenylalkyl, imidazolylalkylphenylalkyl, 2-alkylimidazolylalkylphenylalkyl, benzimidazolylalkylphenylalkyl and 2-alkylbenzimidazolylalkylphenylalkyl; wherein R.sup.2 is selected from hydrido, alkyl, cycloalkyl, akenyl, alkynyl, haloalkyl, benzyl, alkylphenylalkyl, alkoxyphenylalkyl, halophenylalkyl, phenethyl, cycloalkylalkyl, halocycloalkylalkyl, alkylcycloalkylalkyl, alkoxycycloalkylalkyl and naphthylalkyl; wherein Y is selected from carboxylic acid, hydroxamic acid, phosphonic acid and tetrazolyl; or a pharmaceutically-acceptable salt, amide or ester thereof. Compounds of the formula are species-specific inhibitors of C. albicans with little effect on human NMT enzyme and thus would be useful in treating C. albicans fungal infections in humans.
描述了以Seryl-lysyl为基础的肽和肽类拟物化合物作为酶N-肟基转移酶的抑制剂,以提供对真菌Candida albicans的选择性控制。特别感兴趣的肽类拟物化合物是具有以下公式的化合物:其中R.sup.1从氨基烷基,对氨基烷基苯基烷基,咪唑基烷基苯基烷基,2-烷基咪唑基烷基苯基烷基,苯并咪唑基烷基苯基烷基和2-烷基苯并咪唑基烷基苯基烷基中选择;其中R.sup.2从氢代,烷基,环烷基,烯基,炔基,卤代烷基,苄基,烷基苯基烷基,烷氧基苯基烷基,卤代苯基烷基,苯乙基,环烷基烷基,卤代环烷基烷基,烷基环烷基烷基,烷氧基环烷基烷基和萘基烷基中选择;其中Y从羧酸,羟肟酸,膦酸和四唑基中选择;或其药学上可接受的盐,酰胺或酯。该公式的化合物是对C. albicans具有种属特异性的抑制剂,对人类NMT酶的影响很小,因此在治疗人类C. albicans真菌感染方面可能会有用。
