A series of novel fused heterocycle methyl esters were designed and synthesized as human nonpancreatic secretoryphospholipaseA2 (hnps-PLA2) competitive inhibitors. Among the 22 synthesized compounds, 17 quinoline-4-methyl esters displayed hnps-PLA2 inhibition activity in the in vitro bioassay. The IC50 value for the best compound 3o was 1.5 μM. The structure-inhibition–activity relationships of the

les intercalators that stabilize telomeric DNA/RNA hybrid (tDRH) structures by up to 7.2 °C at a 1 μM ligand concentration while having negligible affinity for DNA/DNA duplexes, although with a low affinity for quadruplex DNA. We have used molecular modelling studies to rationalize this selectivity, concluding that the methylene spacer between the terminal benzimidazole and phenylene moieties plays
