N-[[[(5-chloro-2-benzothiazolyl)thiolphenyllacetyll-L-cysteine (WY-45,368) is a potent inhibitor of human skin fibroblast collagenase. Kinetic data show that the inhibition is competitive, with a Ki of 3.5 microM. WY-45,368 inhibits neither of two other metalloproteinases, thermolysin and angiotensin converting enzyme, nor does it inhibit clostridial collagenase--thus indicating specificity for mammalian collagenase.
N-[[[(5-氯-2-苯并噻唑基)硫代苯基]乙酰基]-L-半胱氨酸(WY-45,368)是一种有效的人皮肤成纤维细胞胶原酶抑制剂。动力学数据表明,这种抑制作用是竞争性的,其抑制常数(Ki)为3.5微摩尔。WY-45,368既不抑制另外两种金属蛋白酶——嗜热菌蛋白酶和血管紧张素转换酶,也不抑制梭菌胶原酶,因此表明它对哺乳动物胶原酶具有特异性。
