The inhibition of glyoxalase I enzyme to increase cellular levels of methylglyoxal has been developed as a rationale for the production of anticancer agents. Synthesis of a peptidomimetic analog of the previously prepared potent glyoxalase inhibitor, S-(p-bromobenzyl)glutathione (PBBG), was accomplished by inserting a urea linkage, NH-CO-NH, to replace the gamma-glutamyl peptide bond. Thus, the target
已经开发出抑制乙二醛酶I酶以增加甲基乙二醛的细胞水平作为生产抗癌剂的理由。通过插入尿素键NH-CO-NH取代γ-谷氨酰肽键,可以合成先前制备的有效乙二醛酶抑制剂S-(对-溴苄基)谷胱甘肽(PBBG)的拟肽类似物。因此,与PBBG相比,目标化合物γ-(L-γ-氮杂谷氨酰基)-S-(对溴苄基)-L-半胱氨酰甘氨酸6是乙二醛酶I的有效抑制剂,几乎没有活性降低。但是,与PBBG不同,6对肾脏匀浆或纯化的γ-谷氨酰转肽酶的酶降解作用完全抵抗。
