TASP 0277308 is a potent and selective sphingosine 1-phosphate 1 (S1P1) receptor antagonist (IC50 = 7.8 nM). TASP 0277308 inhibits S1P-induced chemotaxis (IC50 = 1.1-1.6 nM), HUVEC cell proliferation (IC50 = 3-3.6 nM) and suppresses angiogenesisin vivo.

H-Gly-Pro-OH is a dipeptide composed of glycine and proline, and is an end product of collagen metabolism that is further cleaved by prolidase.

D-(-)-3-Phosphoglyceric acid disodium (3-Phospho-D-glyceric acid disodium) is an intermediate in glycolysis/gluconeogenesis and the biosynthesis of serine, glycine, and threonine, competitively inhibiting yeast enolase.
