| 应用 |
A potent and selective pan-ARK inhibitor |
| 产品介绍 |
VX-680 (Tozasertib, MK-0457)是一种pan-Aurora抑制剂，对Aurora A作用最强，Kiapp为0.6 nM，而对Aurora B/Aurora C的作用稍弱，对Aurora A选择性比其他55种激酶强高100倍。 |
| 备注 |
VX-680 (Tozasertib, MK-0457) is a pan-Aurora inhibitor, mostly against Aurora A with Kiapp of 0.6 nM, less potent towards Aurora B/Aurora C and 100-fold more selective for Aurora A than 55 other kinases. Phase 2. |
| 生化机理 |
Tozasertib is a potent pan-ARK inhibitor but favors ARK-1 (Ki = 0.6 nM) over ARK-2 (Ki = 18 nM) or ARK-3 (Ki = 4.6 nM). It shows selectivity against a panel of more than 190 different protein kinases. Tozasertib effectively inhibits proliferation of several different cell lines of clear cell renal carcinoma (IC50 < 10 μM), inhibiting H3 histone phosphorylation and increasing apoptosis. By depleting ARK activity, tozasertib disrupts bipolar spindle formation during mitosis, arresting cell cycle progression at the G2/M phase. |
