Several anthranilamide-based 2-phenylcyclopropane-1-carboxamides 13a-f, 1,1’-biphenyl-4-carboxamides 14a-f and 1,1’-biphenyl-2-carboxamides 17a-f were obtained by a multistep procedure starting from the (1S,2S)-2-phenylcyclopropane-1-carbonyl chloride 11, the 1,1'-biphenyl-4-carbonyl chloride 12 or the 1,1'-biphenyl-2-carbonyl chloride 16 with the appropriate anthranilamide derivative 10a-f. Derivatives 13a-f, 14a-f and 17a-f showed antiproliferative activity against human leukemia K562?cells. Among these derivatives 13b, 14b and 17b exerted a particular cytotoxic effect on tumor cells. Derivative 17b showed a better antitumoral effect on K562?cells than 13b and 14b. Analyses performed to explore 17b mode of action revealed that it induced an arrest in G2/M phase of cell cycle which was consequent to DNA lesions as demonstrated by the increase in phospho-ATM and γH2AX, two known markers of DNA repair response system. The effect of 17b was also related to ROS generation, activation of JNK and induction of caspase-3 dependent apoptosis.

Structure-activity relationships for lipoprotein lipase agonists that lower plasma triglycerides in vivo

The risk of cardiovascular events increases in individuals with elevated plasma triglyceride (TG) levels, therefore advocating the need for efficient TG-lowering drugs. In the blood circulation, TG levels are regulated by lipoprotein lipase (LPL), an unstable enzyme that is only active as a non-covalently associated homodimer. We recently reported on a N-phenylphthalimide derivative (1) that stabilizes LPL in vitro, and moderately lowers triglycerides in vivo (Biochem. Biophys. Res. Commun. 2014, 450, 1063). Herein, we establish structure-activity relationships of 51 N-phenylphthalimide analogs of the screening hit 1. In vitro evaluation highlighted that modifications on the phthalimide moiety were not tolerated and that lipophilic substituents on the central phenyl ring were functionally essential. The substitution pattern on the central phenyl ring also proved important to stabilize LPL. However, in vitro testing demonstrated rapid degradation of the phthalimide fragment in plasma which was addressed by replacing the phthalimide scaffold with other heterocyclic fragments. The in vitro potency was retained or improved and substance 80 proved stable in plasma and efficiently lowered plasma TGs in vivo.
