Leukotriene C4-d5 (LTC4-d5) contains five deuterium atoms at the 19, 19', 20, 20 and 20 positions. It is intended for use as an internal standard for the quantification of LTC4 by GC- or LC-mass spectrometry. LTC4 is the parent cysteinyl leukotriene produced by the LTC4 synthase catalyzed conjugation of glutathione...

(+)-Nutlin-3 is the enantiomer and less active form of the p53-Mdm2 protein-protein interaction inhibitor (-)-nutlin-3 (Cay-18585). It inhibits the interaction between p53 and Mdm2 150-fold less potently than (-)-nutlin-3 with an IC50 value of 13.6 µM. (+)-Nutlin-3 has been used as a negative control for the...

Arachidonyl ethanolamide (AEA, Cay-90050) is an endogenous lipid neurotransmitter with cannabinergic activity, binding to both the central cannabinoid (CB1) and peripheral cannabinoid (CB2) receptors. Fatty acid amide hydrolase (FAAH) is the enzyme responsible for the hydrolysis and inactivation of AEA. Metabolism...

Leukotriene A4 (LTA4) hydrolase/aminopeptidase is a bifunctional zinc metalloenzyme that both catalyzes the synthesis of LTB4 (Cay-20110) from LTA4 and cleaves the chemotactic peptide Pro-Gly-Pro. SC-57461A is a potent, orally active inhibitor of LTA4 hydrolase that blocks ionophore-stimulated LTB4 synthesis in...
