Areas of Specialization
Xenobiotics Metabolism and Pharmacokinetics/Toxicokinetics
Current R&D/S&T Activities

Ø Pharmacokinetic/Toxicokinetic studies: In-vivo pharmacokinetics/toxicokinetics (bioavailability, excretion, tissue distribution and dose proportionality studies) of xenobiotics in preclinical animals using different route of administration (Oral, I.V., I.P., I.M. etc.).

Ø  Bio-analysis: Method development and validation for xenobiotics quantification in different matrices (e.g. blood, plasma, urine, tissues, water and food commodities etc.) using UPLC, LC-MS/MS and GC-MS/MS.

Ø  In-vitro metabolism: Metabolic stability, metabolite identification, CYP450/UGTs phenoytping & inhibition studies of xenobiotics using recombinant enzymes/microsomes/S9 fraction/hepatocytes as test system.

Ø  Interaction studies: Pesticide-drug, drug-drug and food-drug interaction studies using in-vitro test systems and in-vivo prediction using mathematical models.

Ø  Human pharmacokinetics prediction: Allometry scaling and in-vitro in-vivo extrapolation (IVIVE) using in-vitro and in-vivo preclinical data for predicting the pharmacokinetics/toxicokinetics in humans.

Ø  Risk assessment: Integration of species difference in metabolism & toxicokinetics, and PBPK modelling for assessing the risk of environmental toxicants/toxins exposure on human health.

ØPesticide Residue Analysis: Multi pesticide residues determination in different food commodities such as vegetables, fruits, cereals and pulses as per NABL.
