Chalepensin
Based on 1 Customer Validation
Chalepensin is a nematicide and CYP inhibitor. Chalepensin inhibits CYP2A6, CYP1A1, CYP1A2, CYP2A13, CYP2C9, CYP2D6, CYP2E1, and CYP3A4 to varying degrees, with IC50 values of 82.3 μM, 2.86 μM, 3.01 μM, 0.21 μM, 6.58 μM, 1.67 μM, 61.1 μM, and 61.7 μM, respectively. Chalepensin potently and selectively kills third-stage infective larvae of Strongyloides venezuelensis.

Chalepensin inhibits CYP1A1, CYP1A2, CYP2A13, CYP2C9, CYP2D6, CYP2E1, and CYP3A4 to varying degrees[1].
Chalepensin (1-50 μM; 24-72 h) potently and selectively kills third-stage infective larvae (L3) of *Strongyloides venezuelensis*, with an LC50 of 3.4 µM at 72 h and a selectivity index of 990.0, exhibiting activity comparable to that of ivermectin[2].
Chalepensin (1-60 μM; 24-72 h) potently and selectively kills parthenogenetic adult females of *Onchocerca volvulus*, with an LC50 of 16.8 μM at 72 h and a selectivity index of 200.4; this compound exhibits superior activity to graveoline and comparable activity to ivermectin at low concentrations[2].
Chalepensin (10 μM-6 mM; 72 h) exhibits extremely low cytotoxicity against Vero cells[2].
