A series of multi-substituted oximes were prepared and their potencies for inhibiting-lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) activity were evaluated in vitro. Among them, compounds 3a, 3b, and 3m were identified to display a micromolar potency for inhibiting Lp-PLA(2) in whole human plasma and isolated human LDL. Based on these results, structure-activity relationship was studied on modification of three parts of R-1, R-2, and R-3 to identify a potent pharmacophore for Lp-PLA(2). In an attempt to introduce various functional groups at R-2 and R-3, we discovered that replacement of less lipophilic groups led to an increase of inhibitory activity. Among the tested oxime derivatives, cyano- and morpholino-substituted analogue 4f at R-2 and R-3 had the highest potency with an IC50 value of 0.05 mu M in whole human plasma. (c) 2006 Elsevier Ltd.
