Cepharanthine

Cepharanthine is a natural product that can be isolated from the plant Stephania cephalantha Hayata. Cepharanthine has anti-severe acute respiratory syndrome coronavirus 2 (anti-SARS-CoV-2) activities. Cepharanthine has good effective in suppressing viral proliferation (half maximal (50%) inhibitory concentration (IC50) and 90% inhibitory concentration (IC90) values of 1.90 and 4.46 μM[1]. Cepharanthine can also effectively reverses P-gp-mediated multidrug resistance in K562 cells and increase enhances the sensitivity of anticancer agents in xenograft mice model[2][3]. Cepharanthine shows inhibitory effects of human liver cytochrome P450 enzymes CYP3A4, CYP2E1 and CYP2C9. Cepharanthine has antitumor, anti-inflammatory and antinociceptive effects[4][5][6][7][8].
