Isoxazolo[3,4-d]pyridazinones and analogues as Leishmania mexicana PDE inhibitors
摘要:
A series of isoxazolopyridazinones and analogues has been prepared and evaluated as Leishmania mexicana phosphodiesterase (PDE) inhibitors. Some of the synthesized compounds showed a moderate PDE inhibitory activity at 100 muM and preliminary structure-activity relationships were discussed.

doses of 3-20 mg kg-1 po, showed good antinociceptive activity, reducing by more than 50% the number of writhes with respect to controls. Compounds 16c, 19a, 20a, and 28 were the most potent of the series because they were able to induce a potent antinociceptive effect at a dose of 3 mg kg-1 po. None of the active compounds at the analgesic dose provoked any visible change in normal behavior, as demonstrated
