  • Bioperine
  • NSC 21727
  • N-Piperoylpiperidin

Piperine is a natural alkaloid that can be isolated from black pepper. It activates transient receptor potential vanilloid type 1 receptor (TRPV1; EC50 = 38 µM) and modulates GABAA receptors (EC50s = 43-60 µM).1,2 At similar levels, piperine inhibits both monoamine oxidases (MAOs), with IC50 values of 21 and 7 µM for MAO-A and MAO-B, respectively.3 Like other natural compounds containing methylenedioxyphenyl substituents, piperine affects cytochrome P450 (CYP) isoforms, inhibiting CYP3A species (Ki ~ 5 µM) and increasing expression of CYP1A and CYP2B in liver.4 It also has a biphasic effect on P-glycoprotein activity.5
