We recently presented that compounds 4a-b moderately inhibited leukotriene (LT) formation in human neutrophils. For structural derivatization of 4a-b, novel thirty-six title compounds were synthesized and led to more potent inhibition of LT biosynthesis in activated human neutrophils exemplified by compounds 15, 27-30, 32-37, 41, 42 with IC(50) values in the range of 1.6-3.5 ##M. Moreover, more ..

Title: Pyrazol-3-propanoic acid derivatives as novel inhibitors of leukotriene biosynthesis in human neutrophils.
Abstract: We recently presented that compounds 4a-b moderately inhibited leukotriene (LT) formation in human neutrophils. For structural derivatization of 4a-b, novel thirty-six title compounds were synthesized and led to more potent inhibition of LT biosynthesis in activated human neutrophils exemplified by compounds 15, 27-30, 32-37, 41, 42 with IC(50) values in the range of 1.6-3.5 ##M. Moreover, compounds 32, 35, 42, 43 and 44 showed a substantial inhibition of platelet COX-1 activity with IC(50) of 2.5, 0.041, 0.3, 0.9 and 0.014 ##M, respectively, leading up to dual acting inhibitors. On the basis of their high potency in cellular environment, these straightforward pyrazole-3-propanoic acid derivatives may possess potential in the design of more potent compounds for intervention with inflammatory and allergic diseases.
