Total synthesis of antigenic Glycolipids:

Total synthesis of the phospholipomannan (PLM) which was found in cell wall of Candida albicans. It is most widespread human pathogen responsible for cutaneous and systemic fungal infections, synthesize a unique sequences of β-1,2-oligomannan on its cell surface that act as adhesion, induce production of pro-inflammatory cytokines and antibodies.
And it is highly immunogenic due to its β-1,2-mannan structural motif, which is absent in human host. The PLM is a strong TNF-α inducer in vivo and in vitro. The target molecule contain synthetic challenges such as an unusual β-1,2-oligomannan, Anomeric phosphodiester and phyto sphingosine linked to saccharide through phosphate.

Isolation of bioactive metabolites from Natural resources: we are focusing the several distinct scientific exploratory projects which is mainly related to isolation and characterization of bioactive metabolite from endophytic microbes, Medicinal plants and marine organism for new chemical entities to achieve the new biological knowledge.

Isolation of distinct metabolites from microbes: Phialomustin A-D (1-4), four new distinct bioactive metabolite with an unprecedented azaphilone derived skeleton form an endophytic fungus isolated from corms of Crocus sativus showed highest ITS-5.8S-ITS2 ribosomal gene sequence and morphological analysis sequence similarity more than 99% homology with Phialophora mustea.

Chemical modification and crystallization as an alternative source for the isolation of bioactive molecules from the endophytic fungus, Cryptosporiopsis sp.: Isolation of distinct metabolite from an endophyte of Clidemia hirta was revaluated of the ITS region displayed a 98% sequence similarity with Cryptosporiopsis californiae.

Marine Microbes: Isolation of distinct cyclic dipeptide from Streptomyces sp.:

Plants Metabolite: 3 new and several know distinct carbazole alkaloids isolated from the stem of Murraya koenigii.


Natural Product a versatile biochemical tools and their application: 
In addition to that we are keen on to emphasize how natural products or engineered analogs can be used as chemical tools to apprehend some biological problems and create small-molecule probes that interact with a specific protein in a broader biological knowledge for understanding of what makes a high-quality probe which is lacking. We would like to set up the distinct examples of natural products and their derivatives as biochemical tools to explore biological phenomena and assemble biochemical pathways are presented in Figure 1.

Medicinal chemistry: My research group are also actively involved in the semisynthetic modification of lead natural product to achieving the new biological knowledge.
