Protopine is the isoquinoline alkaloid found primarily in the plant families Berberidaceae, Ranunculaceae, Rutaceae, Fumariaceae. It has diverse biological activities, such as anti-thrombotic, anti-inflammatory, anti-parasitic activity, antimicrobial activity, as well as hepatoprotective effects in animal models. The biological activities of protopine are associated with its ability selectively inhibits K(ATP) channels by targeting on SUR1 subunit. In addition, was discovered that β2 -adrenoceptor (β2 -AR) is a target for antiasthma activities of protopine. On this target, binding of the drug occurs on the amino acid residual of Ser 169 through the formation of hydrogen bonds and receptor‐drug bumps.

Sample Use Guides
Protective action of protopine against experimental liver injury in mice: administration of two doses of protopine at 50 and 100 mg.kg-1 in an interval of 8 to 24 h before i.p. injection of CCl4, acetaminophen or thioacetamide.
Route of Administration:
Oral
The effects of protopine on human platelet aggregation and arachidonic acid (AA) metabolism via cyclooxygenase (COX) and lipoxygenase (LOP) enzymes were examined. Platelet aggregation induced by various platelet agonists (AA, ADP, collagen and PAF) was strongly inhibited by protopine in a concentration-related manner. The IC50 values (microM) of protopine (mean +/- SEM) against: AA; 12 +/- 2: ADP; 9 +/- 2: collagen; 16 +/- 2 and PAF; 11 +/- 1, were much less than those observed for aspirin.
