生物活性

Ch55 is a potent synthetic retinoid. Ch55 binds to RAR-α and RAR-β receptors with high affinity. Ch55 displays low affinity for cellular retinoic acid binding protein (CRABP). Ch55 is a potent inducer of the differentiation of HL60 cells with an EC50 of 200 nM. Ch55 can be used for cancer research[1][2].

体外研究
(In Vitro)

Ch55 inhibits squamous cell differentiation of rabbit tracheal epithelial cells by inhibiting type I transglutaminase activity (EC50 = 0.02 nM) and increasing cholesterol sulfate levels (EC50 = 0.03 nM). Ch55 also induce differentiation of embryonic carcinoma F9 cells and melanoma S91 cells (EC50s = 0.26 and 0.5 nM, respectively), and inhibits the induction of ornithine decarboxylase activity in 3T6 fibroblasts (EC50 = 1 nM)[1].

In Vivo:

请根据您的实验动物和给药方式选择适当的溶解方案。以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液,再依次添加助溶剂:

——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议您现用现配,当天使用; 以下溶剂前显示的百
分比是指该溶剂在您配制终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶

  • 1.

    请依序添加每种溶剂: 10% DMSO    90% corn oil

    Solubility: ≥ 2.5 mg/mL (6.86 mM); Clear solution

    此方案可获得 ≥ 2.5 mg/mL (6.86 mM,饱和度未知) 的澄清溶液,此方案不适用于实验周期在半个月以上的实验。

    以 1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。
