A series of xanthine derivatives in which a methylene was inserted at position 8 of xanthine scaffold was synthesized and evaluated as inhibitors of dipeptidyl peptidase 4 (DPP-4) for the treatment of type 2 diabetes. As the results of structure–activity relationship (SAR) study of the series, the compounds with 4-methyl-quinazoline-2-yl-methyl group at N-1 position and 2-aminoethylaminomethyl group gave better activities. Compounds H4 and H9 showed good DPP-4 inhibition and more than 100-fold selectivity over DPP-7 and DPP-8.
研究人员合成了一系列黄嘌呤衍生物,其中在黄嘌呤支架的第 8 位插入了一个亚甲基,并将其评估为二肽基肽酶 4(DPP-4)的抑制剂,用于治疗 2 型糖尿病。该系列化合物的结构-活性关系(SAR)研究结果表明,N-1 位上带有 4-甲基-喹唑啉-2-基甲基和 2-氨基乙基氨基甲基的化合物具有更好的活性。化合物 H4 和 H9 对 DPP-4 有良好的抑制作用,对 DPP-7 和 DPP-8 的选择性超过 100 倍。
