Design and synthesis of biologically active novel heterocycles and structure elucidation by 1D and 2D NMR analysis.
Many of the drugs in human medicine are chiral because they bind to enzymes and receptors to elicit biological activity. Both enzymes and receptors are chiral and therefore in a chiral drug molecule one of the enantiomer is more active than the other.
Most drugs are also heterocyclic in nature. Our research has focused on conceiving ideas of what heterocycles might show activity against a particular disease based on their bindings at enzyme or receptor level and to investigate the role of chirality in these molecules.
We have developed novel synthetic methodologies for stereoselective synthesis of these heterocycles possessing chiral centers and we believe these synthetic methodologies will be useful for the synthesis of other drugs.
