Synthesis of New Pyridazine Derivatives as Potential Anti-HIV-1 Agents

We herein report conventional and microwave-assisted methods for the synthesis of a series of compounds containing some bivalent ion chelating requirements useful to exert potential HIV-1 integrase (IN) enzyme inhibition activity. The biological screening highlighted that only derivative 5 proved to be a strand-transfer step inhibitor of the virus integration process at micromolar concentration.
