[Display omitted]
•Designed and synthesized a set of triazole containing quinine conjugates.•Synthesized conjugates shows promising antimalarial activity.•2D-QSAR studies supports the biological data.•Developed QSAR model could be useful tool for new drug development.
Click chemistry technique led to novel 1,2,3-triazole-quinine conjugates 8a–g, 10a–o, 11a–h and 13 utilizing benzotriazole-mediated synthetic approach with excellent yields. Some of the synthesized analogs (11a, 11d–h) exhibited antimalarial properties against Plasmodium falciparum strain 3D7 with potency higher than that of quinine (standard reference used) through in vitro standard procedure bio-assay. Statistically significant BMLR-QSAR model describes the bio-properties, validates the observed biological observations and identifies the most important parameters governing bio-activity.
