    Pharmacology and Toxicology


  • Department of Pharmacology and Toxicology has the facilities to carry out pharmacological screening of NCEs. The department can enter into project collaborations in regulatory toxicological testing, viz., acute, sub-chronic and chronic toxicity testing. The departmental research activities are concentrated in the following areas :

  • Opioid tolerance, supersensitivity and dependence mechanisms

  • Role of different subtypes of angiotensin receptors in hypertension and diabetic vascular complications

  • Understanding the mechanisms of diabetic complication and development of NIDDM & insulin resistance models in rodents; screening of synthetic and natural products for their antidiabetic activity

  • Role of alpha adrenoceptors in benign prostatic hyperplasia

  • Understanding the molecular mechanisms involved in ischaemic stroke

  • Evaluation of novel neuroprotective approaches for the treatment of cerebral ischemia

  • Development of animal models of cerebral ischemia

  • Understanding the mechanisms of diabetic neuropathy

  • Role of adenosine receptors subtypes in diabetic neuropathic pain

  • Evaluation of various neuroprotective approaches in diabetic neuropathy

  • Screening of NCEs for antileismanial activity.

  • Development of rat model for Alzheimer’s disease and screening of NCEs on learning and memory in rats

  • Production of monoclonal antibodies against Plasmodium yoelii nigeriensis antigens with the objective of characterization of protective antigens

  • Molecular mechanisms of protection, cytoadherence, immune evasion and red cell invasion in malaria

  • Biotherapeutics and chemotherapeutics evaluation of potential antimalarial, antitubercular, antileishmanial and antiamoebic agents in vitro and in vivo

  • Study of the opioids-induced bidirectional molecular signaling within the neuroimmune network with a view to develop new immunomodulators.

  • Histone modifications as targets for drug discovery

  • Molecular mechanism involved in toxicant and oxidative stress induced process of cell death
