A series of uniquely functionalized 2,3,-dihydro-1-pyyrolo[3,4-]quinolin-1-one derivatives were synthesized in one to two steps by utilizing a post-Ugi modification strategy and were evaluated for antileishmanial efficacy against visceral leishmaniasis (VL). Among the library compounds, compound 5m exhibited potential antileishmanial activity (CC = 65.11 μM, SI = 7.79, anti-amastigote IC = 8.36 μM). antileishmanial evaluation of 5m demonstrated 56.2% inhibition in liver and 61.1% inhibition in spleen parasite burden in infected Balb/c mice (12.5 mg kg, i.p.). pharmacokinetic study ascertained the stability of 5m in both simulated gastric fluid and simulated intestinal fluid. All the active compounds passed the PAINS filter and showed no toxicity in predictions.
