Chemical structure of chelerythrine chloride.

Product Usage Information

Chelerythrine Chloride is supplied as a lyophilized powder. For a 10 mM stock, reconstitute the 5 mg in 1.30 ml DMSO. Working concentrations and length of treatment can vary depending on the desired effect, but it is typically used at 1-20 µM either as a pretreatment for 15 min-1 hr prior to treating with a stimulator or used alone with varying treatment times lasting up to 24 hr.

Storage

Store lyophilized or in solution at -20ºC, desiccated. Protect from light. In lyophilized form, the chemical is stable for 24 months. Once in solution, use within 3 months to prevent loss of potency. Aliquot to avoid multiple freeze/thaw cycles.

Background

Chelerythrine is a benzophenanthridine alkaloid that elicits a wide range of biological responses. It was initially reported to be a potent PKC inhibitor (IC50 = 660 nM) through interaction with the catalytic domain, competitive with respect to the phosphate acceptor, noncompetitive with respect to ATP (1), and is often used in research as a means to inhibit PKC activation (2-4). However, subsequent studies have shown that chelerythrine is not a potent PKC inhibitor and its effects are independent of PKC inhibition (5,6). Researchers have demonstrated that chelerythrine activates JNK and p38 through an oxidative stress mechanism (6), inhibits Bcl-xL by preventing Bcl-xL-Bak BH3 peptide binding (IC50 = 1.5 μM) and disrupting the interaction between Bcl-xL and Bax (7), and induces apoptosis (6-8).
