Ilomastat (Synonyms: 伊洛馬司他; GM6001; Galardin)
Ilomastat (GM6001) 是一種有效、廣譜的基質(zhì)金屬蛋白酶 (MMP) 抑制劑，能夠抑制 MMP 的活性， IC50 值分別為 1.5 nM (MMP-1)，1.1 nM (MMP-2)，1.9 nM (MMP-3)，0.5 nM (MMP-9)，對人皮膚成纖維細胞膠原酶 (MMP-1) 的 Ki 值為 0.4 nM。
生物活性
Ilomastat (GM6001) is a potent and broad spectrum matrix metalloprotease (MMP) inhibitor, inhibits MMPs (IC50s, 1.5 nM for MMP-1; 1.1 nM for MMP-2; 1.9 nM for MMP-3; 0.5 nM for MMP-9), with a Ki of 0.4 nM for human skin fibroblast collagenase (MMP-1).
體外研究(In Vitro)
Ilomastat (GM6001) inhibits human skin fibroblast collagenase, thermolysin and elastase with Kis of 0.4 nM, 20 nM, 20 nM, resepctively[1]. Ilomastat (0.1-10 nM) inhibits gelatinase A and gelatinase B produced by T-cells. Ilomastat inhibits T-cell homing[4].
體內(nèi)研究(In Vivo)
Ilomastat (GM6001) (400 μg/mL) inhibits corneal ulceration after severe alkali injury in animals[2]. Ilomastat (GM6001) significantly suppresses intimal hyperplasia and intimalcollagen content. Ilomastat increases lumen area in stented arteries, shows no activity on proliferation rates in rabbit model after stenting[3].
