Abstract

•A series of twenty four novel 1,4,5 trisubstituted 1,2,3-triazoles were synthesized.•Four compounds exhibited in vitro antiplasmodial activity in low micromolar range.•One compound showed 89.9% parasitaemia inhibition in in vivo antimalarial activity.•Compounds significantly boosted p53 protein levels.

In a quest to discover new drugs, we have synthesized a series of novel β-amino alcohol grafted 1,2,3-triazoles and screened them for their in vitro antiplasmodial and in vivo antimalarial activity. Among them, compounds 16 and 25 showed potent activity against chloroquine-sensitive (Pf3D7) strain with IC50 of 0.87 and 0.3 μM respectively, while compounds 7 and 13 exhibited better activity in vitro than the reference drug against chloroquine-resistance strain (PfK1) with IC50 of 0.5 μM each. Compound 25 showed 86.8% in vivo antimalarial efficacy with favorable pharmacokinetic parameters. Mechanistic studies divulged that potent compounds significantly boosted p53 protein levels to exhibit the antimalarial activity.
