HYPOPHYLLANTHIN Usage And Synthesis

Description

Hypophyllanthin is an active principle of P. amarus, a plant studied for its potential to treat hepatotoxicity. In Caco-2 cells 100 μM hypophyllanthin has been shown to reversibly inhibit P-glycoprotein (also known as multidrug resistance protein 1 (MDR1)) function without effect on MDR2 activity.

Uses

Hypophyllanthin can be used to study the modulation of NSAID-induced, ER stress-mediated apoptosis in Caco-2 cells by different polyphenolic antioxidants.

in vitro

previous study found that hypophyllanthin could inhibit p-gp function with comparable potencies, but could not affect mrp2 activity. when hypophyllanthin was washed out before addition of substrate, the inhibitory action against p-gp function was lost. these results indicated the reversibility of the inhibition. moreover, prolonged exposure of the caco-2 cells to hypophyllanthin up to 7 days had no effect on p-gp function [1].

in vivo

a previous study was conducted to evaluate the effect of carbofuran on estrous cycle and follicular growth in virgin wister rats as well as recovering from the damaged estrous cycle with treatment of hypophyllanthin. hypophyllanthin is non-steroidal plant molecule with estrogen-like activities, but with an estrogen-type activity. hypophyllanthin was capable of interacting with estrogen receptors, showing both agonist and antagonist methods of action. therefore, hypophyllanthin was found to be systemically transformed into enterolignan, which is known to be responsible for augmenting estrus cycle in rats [2].
