應用

OBAA may be used in PLA2-mediated cell signaling studies.

生化／生理作用

OBAA is a phospholipase A2 inhibitor and prevents the melittin-induced influx of Ca+2 in trypanosomes. It inhibits the generation of ROS when epithelial and endothelial cells are treated with cholic acid.
OBAA is a potent inhibitor of phospholipases.

The barrier functions in epithelial and endothelial cells seem to be very important for maintaining normal biological homeostasis. However, it is unclear whether or how bile acids affect the epithelial barrier. We examined the bile acid-induced disruption of the epithelial

In contrast with mammalian cells, little is known about the control of Ca2+ entry into primitive protozoans. Here we report that Ca2+ influx in pathogenic Trypanosoma brucei can be regulated by phospholipase A2 (PLA2) and the subsequent release of arachidonic

Phospholipase A2

Phospholipase A2 (PLA2) designates a class of enzymes that hydrolyze the sn-2 ester of glycerophospholipids to produce a fatty acid and a lysophospholipid. It has become clear that some of these enzymes liberate arachidonic acid in mammalian cells for the biosynthesis of eicosanoids, and thus there has been considerable interest in developing PLA2 inhibitors. Based on amino acid sequences, there are now more than 12 distinct groups of mammalian PLA2s, as well as many non-mammalian forms, all of which have been classified into 14 distinct groups with many subgroups.
