Biological Activity for Ch 55

Ch 55 is a highly potent synthetic retinoid that has high affinity for RAR-α and RAR-β receptors and low affinity for cellular retinoic acid binding protein (CRABP). Inhibits rabbit tracheal epithelial cell differentiation by inhibiting transglutaminase and increasing cholesterol sulfate (EC₅₀ values are 0.02 and 0.03 nM respectively). Induces differentiation of embryonic carcinoma F9 and melanoma S91 cells (EC₅₀ values are 0.26 and 0.5 nM respectively) and inhibits the induction of ornithine decarboxylase activity in 3T6 fibroblasts (EC₅₀ = 1 nM).

For more information about how Ch 55 may be used, see our protocol: Highly Efficient Generation of CiPSCs from MEFs
