Multisubstrate adducts as potential inhibitors of S-adenosylmethionine dependent methylases: inhibition of indole N-methyltransferase by (5H-deoxyadenosyl)[3-(3-indolyl)propyl-1-yl]methylsulfonium and (5'-deoxyadenosyl)[4-(3-indolyl)but-1-yl]methylsulfonium salts

the indole N-methyltransferase reaction have been designed in which a structural moiety representing the nucleophilic methyl acceptor is attached through the sulfur atom to the 5-(methylthio)adenosine and/or methionine moieties of the methyl donor, S-adenosyl-L-methionine. Indole derivatives attached through a 4-(3-indolyl)butyl sulfide or a 3-(3-indolyl)propyl sulfide linkage to 5'-thioadenosine or
已经设计了吲哚N-甲基转移酶反应的多底物加合物,其中代表亲核甲基受体的结构部分通过硫原子连接到甲基供体S-腺苷-的5-(甲硫基)腺苷和/或蛋氨酸部分。 L-蛋氨酸。已经合成了通过4-(3-吲哚基)丁基硫化物或3-(3-吲哚基)丙基硫化物键连接到5'-硫代腺苷或高半胱氨酸的吲哚衍生物,以及它们相应的甲基s盐。已经测定了这些化合物抑制兔肺吲哚N-甲基转移酶的能力。腺苷ulf盐(5'-脱氧腺苷)[4-(3-吲哚基)丁-1-基]甲基高氯酸and和(5' 发现高氯酸-脱氧腺苷基] [3-(3-吲哚基)丙-1-基]-甲基ulf是该酶的抑制剂,其Ki分别为12和44 microM。这些化合物均不能有效抑制由纯化的猪儿茶酚O-甲基转移酶催化的3,4-二羟基苯甲酸的甲基化。
