Abstract
An efficient pathway was disclosed for the synthesis of 3-chloro-6-nitro-1
-indazole derivatives by 1,3-dipolar cycloaddition on dipolarophile compounds
and
. Faced the problem of separation of two regioisomers, a click chemistry method has allowed us to obtain regioisomers of triazole-1,4 with good yields from 82 to 90% were employed. Also, the antileishmanial biological potency of the compounds was achieved using an MTT assay that reported compound
as a promising growth inhibitor of
. Molecular docking demonstrated highly stable binding with the Leishmania trypanothione reductase enzyme and produced a network of hydrophobic and hydrophilic interactions. Molecular dynamics simulations were performed for TryR-
complex to understand its structural and intermolecular affinity stability in a biological environment. The studied complex remained in good equilibrium with a structure deviation of ∼1-3 Å. MM/GBSA binding free energies illustrated the high stability of TryR-
complex. The studied compounds are promising leads for structural optimisation to enhance the antileishmanial activity.
