Overview | Missions and goals | Competencies | People | Area of research | Facilities | Current research | Projects

Bio-organic Chemistry group deals with natural products, biocatalysis, organocatalysis, organic synthesis etc. Prospecting the plant as well as microbial biodiversity of the region as well as other parts of the country is one of the broad objectives of the group. The natural plant biodiversity specifically related to medicinal plants used in the traditional medicine is one of the major activities comprising detailed chemistry, identifying bioactive components/fractions/marker molecules, standardization etc. besides, generation of focused libraries based on natural product scaffolds, which has resulted in identifying several bioactive lead molecules.

Mission and goals

In concordance with the missions and goals of the institute, the bio-organic group strives to contribute towards its development and recognition as one of the premier national institutes in the area of drug development, natural products and bio-catalysis. Some important goals set by the group include:

  • Identification of new lead molecules in anti-cancer, anti-inflammatory, anti-arthritic, anti-bacterial, anti-fungal, anti-oxidant, immunomodulation, efflux pump inhibition, bio-enhancers etc.

  • Exploration of high altitude plants for generation of IPR as well as patenting of the bioactive molecules as NCEs.

  • Development of novel industrial biocatalysts and processes based on them


The group has competencies/expertise in the following area

  • Natural product Chemistry of medicinal and aromatic plants (Extraction using NCI, conventional and non-conventional approaches, isolation, characterization, standardization, quality evaluation of plant based formulations, extracts, fractions and pure isolates) .

  • Compound library generation (chemical modifications) based on natural products and establishment of structure activity relationships

  • Molecular structure elucidation.

  • Development of new and novel methodologies for the preparation of chemicals of importance using Organic synthesis and Natural product modification etc.

  • Biotransformations aided through lipases, esterases, dehydrogenases, nitrilases, peroxidases and glycosidases.
