Rhosin

CAS No. : 1173671-63-0

MCE 国际站：Rhosin

产品活性：Rhosin 是一种有效的，特异性的 RhoA 亚家族 Rho GTPases 抑制剂，能特异性的结合 RhoA，抑制 RhoA-GEF 相互作用，K_d 值 ~ 0.4 uM，但不与 Cdc42 或 Rac1，GEF，LARG 相互作用。Rhosin 可诱导细胞凋亡 (apoptosis)。Rhosin 通过增强 D1 中棘神经元的可塑性和降低过度兴奋性来促进应激恢复。

研究领域：GPCR/G Protein  |  Apoptosis

作用靶点：Ras  |  Apoptosis

In Vitro: Rhosin dose-dependently reduces RhoA and p-MLC1 activities of MCF7 cell-derived mammospheres with an EC₅₀ ~30-50 μM, and causes decreased size and reduced number of mammospheres in MCF7 cells.

In Vivo: Rhosin (40 mg/kg; i.p.) treatment prevents social avoidance caused by social defeat stress. Rhosin also blocks sucrose preference deficits induced by defeat in C57Bl6/J (Jackson) mice.
Rhosin (30 µM; bilateral, intra- Nucleus Accumbens (NAc) infusions) attenuates stress-induced social avoidance. Rhosin blocks stress-induced hyperexcitability in NAc dopamine 1 receptor medium spiny neurons (D1-MSNs). Rhosin prevents decreased excitatory transmission on NAc D1-MSNs. Rhosin enhances spine density in defeat mice.
