盐酸松香(Rhosin hydrochloride)

Rhosin hydrochloride 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 hydrochloride 可诱导细胞凋亡。Rhosin hydrochloride 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。

生物活性

Rhosin hydrochloride is a potent, specific RhoA subfamily Rho GTPases inhibitor. Rhosin hydrochloride specifically binds to RhoA to inhibit RhoA-GEF interaction with a K_d of ~ 0.4 uM, and does not interact with Cdc42 or Rac1, nor the GEF, LARG. Rhosin hydrochloride induces cell apoptosis^[1]^[2]. Rhosin hydrochloride promotes stress resiliency through enhancing D1-MSN plasticity and reducing hyperexcitability^[3].

IC₅₀ & Target

Kd: 0.4 uM (RhoA)^[1]

体外研究(In Vitro)

Rhosin hydrochloride 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^[1].

体内研究(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^[3].
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^[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:	D1-GFP or D2-GFP hemizygote mice on a C57BL/6J background^[3]
Dosage:	40 mg/kg
Administration:	I.p.
Result:	Rhosin was systemically administered 15 min prior to defeat to block RhoA activation. While defeat significantly reduced the time that experimental mice spent interacting with a novel mouse, Rhosin administration suppressed this effect without affecting locomotor behaviors.
