Isolation and amino acid sequence of a phospholipase A2 inhibitor from the blood plasma of Agkistrodon blomhoffii siniticus.

abstract：:Aplyronine A is a macrolide isolated from Aplysia kurodai. By monitoring fluorescent intensity of pyrenyl-actin, it was found that aplyronine A inhibited both the velocity and the degree of actin polymerization. Aplyronine A also quickly depolymerized F-actin. The kinetics of depolymerization suggest that aplyronine A...
