  • Binding pose of one of the new virtual compounds, 14′b (pink) bound to serotonin reuptake transporter (SERT) upon molecular docking having most of it in the allosteric site of the protein and superimposed with escitalopram (green) in the allosteric site and a bit of it extending into the central site through the extracellular gate.
  • Binding pose of the same compound 14b rendered as spheres depicting the complete blockade of the central site by virtue of its occupation of the allosteric site and extracellular gate.

The figures described above are excerpts from a recently accepted publication in the journal, “American Journal of Pharmacological Sciences

RESEARCH INTERESTS

I am interested in the design and development of new therapeutic agents by synthesis of heterocyclic scaffolds that may be substituted at various positions by different groups to create an array of compounds which may be screened for any particular pharmacological activity, in-silico, in-vitro or in-vivo with the aim of identifying a lead molecule which may be further optimized by synthetic modification.

CURRENT RESEARCH

I am currently working on the development of new potential inhibitors of the Plasmodium falciparum transketolase. This work requires the construction of the homology model of the protein followed by molecular dynamics simulation to optimize the protein structure. The chosen target compounds are Schiff-bases of the ketone obtained from the oxidation of lanosterol. These target compounds have been docked with the transketolase to establish and identify the ones that have the most potential as inhibitors of the transketolase and possibly act as antimalarial agents. The in-silico part of this project has been completed and the synthesis aspect is in progress. There is a plan for in-vitro assay as well as in-vivo testing using animal models (Swiss, white albino mice).
