A variety of phosphorus amino acid and dipeptide analogues have been synthesized and evaluated as inhibitors of the metalloenzyme leucine aminopeptidase from porcine kidney. Two phosphonate dipeptides were found to be modest inhibitors of the enzyme (8e, Ki = 58 microM; 8h, Ki = 340 microM). The phosphinic acid (17-OH) and phosphinamide (17-NH2) analogues related to bestatin were prepared by condensation
已经合成了多种磷氨基酸和二肽类似物,并被评价为来自猪肾脏的金属酶亮氨酸氨基肽酶的抑制剂。发现两种膦酸酯二肽是该酶的适度抑制剂(8e,Ki = 58 microM; 8h,Ki = 340 microM)。与贝斯汀相关的次膦酸(17-OH)和次膦酰胺(17-NH2)类似物是通过使次膦酸酯氨基酸衍生物11通过三价亚膦酸酯12与亮氨酸异氰酸酯衍生物13缩合而制备的。在抑制LAP方面无异常(17-O-,Ki = 56 microM; 17-NH2,Ki = 40 microM)。还评估了一系列简单的(α-氨基烷基)膦酸和-次膦酸,发现最有效的抑制剂是L-Leu和L-Phe [R] -3e的膦酸类似物,Ki = 0.23 microM; (R)-3h,Ki =0.42μM)。对于(R)-3e(kon = 400 +/- 55 M-1 s-1)和(R)-3h(kon = 445 +/- 50 M-1
