Multi-targeted therapies are gaining attention in the management of multifactorial diseases due to their poly pharmacology, enhanced potency and reduced toxicity. Metabolic disorders like Type 2 diabetes mellitus (T2DM) and obesity necessitate multi-targeted therapy to improve insulin sensitivity, regulate glucose homeostasis and support weight loss. Medicinal plants rich in bioactive compounds exhibit multi-targetted action with minimal side effects.

Protein tyrosine phosphatase 1B (PTP1B) is a major negative regulator of both the insulin and leptin receptor phosphorylation which impacts insulin sensitivity and hence is a major therapeutic target for the treatment of type 2 diabetes and obesity. Identification of PTP1B active site inhibitors has proven to be difficult with none of them clearing the phase II clinical trials. Since the conventional methods of targeting the active site of PTP1B have failed to bring out effective PTP1B inhibitors as potential drugs, recent studies are focussing on identification of potential allosteric inhibitors of PTP1B with better specificity and activity.

Inhibition of epidermal growth factor receptor by ferulic acid and 4-vinylguaiacol in human breast cancer cells.

Biotechnol Lett

February 2018

Department of Biotechnology, Centre for Food Technology, Anna University, Chennai, 600025, India.

Objectives: To examine the potential of ferulic acid and 4-vinylguaiacol for inhibiting epidermal growth factor receptor (EGFR) in human breast cancer cells in vitro.

Results: Ferulic acid and 4-vinylguaiacol limit the EGF (epidermal growth factor)-induced breast cancer proliferation and new DNA synthesis. Western blot analysis revealed both ferulic acid and 4-vinylguaiacol exhibit sustained inhibition of EGFR activation through down-regulation of Tyr 1068 autophosphorylation.

In Vitro Investigation of the Immunomodulatory Potential of Probiotic Lactobacillus casei.

Probiotics Antimicrob Proteins

March 2013

Tissue Culture and Drug Discovery Lab, Centre for Biotechnology, Anna University, Chennai, 600 025, Tamilnadu, India.

The current study investigated the immunomodulatory potential of ethyl acetate soluble supernatant of Lactobacillus casei (LC-EAS) in vitro. The effect of LC-EAS on nitric oxide release was analyzed in RAW 264.7 cells, wherein, an inhibition in nitric oxide production through suppression of inducible nitric oxide synthase mRNA expression was observed.
