Integrated genomic and metabolomic approach for the discovery of novel small molecules with anticancer activity from marine microorganisms

Cancer is considered as one of the deadliest diseases in the world, and its occurrence is increasing day by day because of various factors. Chemotherapy is currently the primary treatment modality in many tumors. However, the development of multidrug resistance (MDR) to chemotherapeutic drugs is a main obstacle for the successful treatment of malignant tumors. Therefore, development of novel chemotherapeutic agents would play a key role in the treatment of refractory or relapsing cancer patients. The natural environment is still the most important supply of novel drugs despite development of combinatorial chemistry, which can quickly generate thousands of new chemicals. Marine environment constitutes rich and biologically productive region constituting most of the species of the world as a result of which there is a higher magnitude of scope for research and investigation to explore the potential of both marine organisms and marine microorganisms as producers of novel drugs. The present investigations will be directed toward the discovery of structurally unique anticancer compounds from marine organisms isolated from Indian Ocean through an integrated genomic and metabolomics approach targeting compounds with novel chemical scaffolds.
