title: Isoxazolo[3,4-d]pyridazinones and analogues as Leishmania mexicana PDE inhibitors.
abstract: 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 microM and preliminary structure-activity relationships were discussed.
