Research Rational Drug Design: A process for drug design which bases the design of the drug upon the structure of its protein target. • Structural mapping of the receptor (protein, P) active site • Identification of ligands (L) of complementary shape and appropriate functionality • Docking of the ligand to the receptor site - predicting a range of PL complexes with different DGPL values 4. Scoring i.e. ranking DGPL and correlating with experimentally determined properties such as IC50 values
Protein • FW: 35389.2 Da • 3 ligands: • 2 PO4 • STI-571 • 313 AA in two segments • 108 and 189 AA long
four criteria to conclude that integrase is theinhibitor target: 1. found to be active against recombinant integrase. 2. infected cells treated with the drug must show an accumulation of 2-LTR circles, resulting from the accumulation of viral cDNA and decreased HIV integration into host 3. integrase mutations must be found in drug-resistant viruses 4, the drug should be inactive in biochemical assays against recombinantintegrases bearing the mutations identified in the drug-resistant viruses DKAs DCQ acids; DCT acids PDP SQL Quinolone derived
