The methanolic extract of Piper lolot, having shown potent inhibitory activity on platelet aggregation induced by arachidonic acid (AA) and platelet activating factor (PAF), was subjected to activity-guided isolation to yield twelve new amide alkaloids, piperlotine A–L (1–12), along with twenty-nine known compounds. Their structures were elucidated on the basis of spectroscopic analysis.

Antiplatelet Medications | Types of antiplatelets

Antiplatelets are types of anticoagulants – medications used to help prevent the formation of blood clots when no injury has occurred. They work by reducing the platelets’ stickiness (viscosity). The most common antiplatelet in use today is the over-the-counter drug aspirin, which has been found to prevent platelet binding and clot formation.
