Review of knowledge for rational design and identification of anti-tubercular compounds
Mohammad Imran Siddiqi, Ashutosh Kumar · Expert Opinion on Drug Discovery · 2009
BACKGROUND: The synergy between tuberculosis and the AIDS epidemic, along with the surge of multi-drug resistant isolates of Mycobacterium tuberculosis, has reaffirmed tuberculosis as a primary public health threat. Discovery of novel anti-tubercular entities is a highly complex and, therefore, more rational design strategies based on our increasing understanding of the fundamental principles of protein-ligand interactions are required. The combination of available knowledge of several 3D protein structures with thousands of anti-tubercular small-molecules have attracted the attention of scientists from all over the world for the application of structure- and ligand-based drug design approaches. OBJECTIVE: In this review, an outline of the recent knowledge concerning rational design that chemists and biomedical scientists are currently using to rapidly identify and design novel anti-tubercular agents is presented. The recent successes in rational design of anti-tubercular agents mentioned in the review could give insights into the wide range of possibilities of using rational drug design methodologies. CONCLUSION: The key conclusion is that future research through the aid of combined ligand and receptor-based design and chemo-bioinformatics will bring not only new hope, but also create a new class of anti-tubercular drugs that will help millions of patients.
