Z62954982 (ZINC08010136) 是一种强效的、选择性的、细胞渗透性强的 Rac1 (IC₅₀=12 μM) 抑制剂，比 NSC23766 (HY-15723A) (IC₅₀=50 μM) 有效性强 4 倍。Z62954982 干扰 Rac1/Tiam1 复合物，降低活性 Rac1 (GTP 结合的 Rac1) 的细胞质水平，而不影响其他 Rho GTPases (如，Cdc42 或 RhoA) 的活性。

Z62954982 (ZINC08010136) is a potent, selective and cell-permeable Rac1 (IC 50 =12 μM) inhibitor that is 4 times more effective than NSC23766 (HY-15723A) (IC 50 =50 μM). Z62954982 disrupts the Rac1/Tiam1 complex and decreases cytoplasmic levels of active Rac1 (GTP-bound Rac1), without affecting the activity of other Rho GTPases (such as Cdc42 or RhoA).

Liquid

Z62954982 (5-100 μM; 4 hours) reduces the intracellular levels of Rac1- GTP in a concentration-dependent manner,and shows the most potent inhibitory action with an IC50 of 12.2 μM in Human SMCs.
Z62954982 (25 μM; 4 hours) significantly reduces the ratio Rac1-GTP/Rac1 and has the most potent inhibitory action (86.0%) in cultured SMCs.
Z62954982 (10-100 μM; 72 hours) causes a concentration-dependent decrease in transendothelial electrical resistance (TER) in both HDMEC and HUVEC monolayers.
has not independently confirmed the accuracy of these methods. They are for reference only.

Z62954982 (intraperitoneal injection; 10 mg/kg every other day or 20 mg/kg daily; 3 weeks) has no obvious signs of toxicity and decreases both phosphorylation of p38 as well as secreted IL-6 in PASMCs in response to hypoxia in both abr and bcr mice.
