ADVANCED MEDICINAL CHEMISTRY – II



Computer aided drug design (CADD): 
            1. Virtual screening: concept, drug likeness screening, focused screening libraries for lead identification, pharmacophore screening, structure based virtual screening and applications.
            2. Molecular modeling: Molecular mechanics, quantam mechanics, modeling ligands for known receptors and unknown receptors.


Rational Drug design: Quantitative structure activity relationship (QSAR): Physico chemical properties: hydrophobicity, electronic effects, steric factors-Taft’s steric factor (Es), molar refractivity, verloop steric parameter, other physico chemical parameters.
Methods used to correlate physico chemical parameters with biological activity: Hansch analysis, Free and Wilson approach, Topliss scheme, bioisosteres, planning a QSAR study. 3D QSAR, molecular graphics based drug design and mathematical methods.
  
Enzyme Inhibitors: A detailed study of the following types of enzyme inhibitors, related drugs and their pharmaceutical significance.
            P.G. Synthease (Cyclooxygenase and Lipoxygenase) inhibitors, 
            Phosphodiesterase (PDE) inhibitors, 
            HMG Co A reductase inhibitors,
            Xanthine oxidase inhibitors,
            Angiotensin convertin enzyme (ACE) inhibitors.  

Anti Viral Agents: Viruses, viral diseases, structure and life cycle of viruses; antiviral agents used against DNA viruses- herpes, chicken pox; and RNA viruses – HIV, influenza.


Chemotherapy of Cancer: Molecular biology of caner: introduction, biochemical basis of cancer, types of cancer, SAR and mechanism of action of anticancer agents, alkylating agents, antimetabolites, antitumor antibiotics. A brief account on cancer chemotherapy and drug resistance.
