Tetrahydropentagamavunon-O (THPGV-O) is assumed to be main metabolite product of biotransformation process of PGV-O. THPGV-O was synthesized by converting PGV-O to the compound by hydrogenation with PdjC as a catalyst. PGV-O potently inhibited the histamine release from ~at mast cells in vitro and in vivo, however, ironically only traces amount of compound was found in the blood. THPGV-O is ass…
Asthma is a chronic inflammatory airway disease involving reversible airway constriction and airway hyperresponsiveness (AHR) to allergens, airway edema, and increased mucus secretion turner cells. To date, exploration of antiasthmatic drug is still being studied both from natural products or sinthetic processes. One of the sinthetic compound is pentagamavunon-O (PGV-O) which possesses anti-inf…
