The effects of prostaglandin E2 (PGE2) are transduced by at least four distinct receptors designated EP1, EP2, EP3, and EP4. GW 627368X is a potent and selective competitive antagonist of the EP4 receptor with additional human TP receptor affinity. In competition radioligand bioassays, GW 627368X had affinity for...

Flavopiridol is an orally bioavailable inhibitor of cyclin dependent kinases (IC50s = ~100, ~100, ~100, and 300 nM for Cdk1, Cdk2, Cdk4, and Cdk7, respectively). It also inhibits TEFb, a complex composed of Cdk9 and cyclin T1, with a Ki value of 3 nM. Flavopiridol inhibits transcription of a CMV promoter in HeLa...

Leukotriene A4-d5 (LTA4-d5) methyl ester contains four deuterium atoms at the 19, 19', 20, 20, and 20 positions. It is intended for use as an internal standard for the quantification of LTA4 methyl ester by GC- or LC-mass spectrometry. LTA4 is synthesized in mast cells, eosinophils, and neutrophils from arachidonic...

all-cis-1,2,3-Docosahexaenoyl glycerol is a polyunsaturated triacylglycerol that contains all-cis docosahexaenoic acid (DHA, Cay-90310) at the sn-1, sn-2, and sn-3 positions.Formal Name: (4Z,4'Z,4''Z,7Z,7'Z,7''Z,10Z,10'Z,10''Z,13Z,13'Z,13''Z,16Z,16'Z,16''Z,19Z,19'Z,19''Z)-4,7,10,13,16,19-docosahexaenoic acid,...
