Ch55 NLT 98%

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]. 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].
