Strengthening microbial cell factories for efficient production of bioactive molecules.

High demand of bioactive molecules (food additives, antibiotics, plant growth enhancers, cosmetics, pigments and other commercial products) is the prime need for the betterment of human life where the applicability of the synthetic chemical product is on the saturation due to associated toxicity and ornamentations. It has been noticed that the discovery and productivity of such molecules in natural scenarios are limited due to low cellular yields as well as less optimized conventional methods. In this respect, microbial cell factories timely fulfilling the requirement of synthesizing bioactive molecules by improving production yield and screening more promising structural homologues of the native molecule.

Immunomodulation-mediated anticancer activity of a novel compound from Brugmansia suaveolens leaves.

Immunomodulation activity-guided fractionation of ethanol extract of Brugmansia suaveolens leaves was carried out to isolate a novel compound SUPH036-022A (1) by co-culturing the test fraction/compound activated PBMC with MCF7 and A549 cancer cell lines. Assessment of immune markers in PBMC, and analysis of apoptosis markers and cell cycle was carried out for cancer cells. The structure of the isolated compound was elucidated by spectral analysis.

Recent advances in cancer immunology and immunology-based anticancer therapies.

Cancer immunotherapies offer promise for cure of cancer with specificity and minimal toxicity. Recent developments in cancer immunology have led to the better understanding of role of immune regulatory mechanisms in cancer. There is rapid progress in this field in the last few years.
