A series of (nitrooxy) alkyl apovincaminates has been synthesized and evaluated for their effects on vertebral and femoral blood flow. These derivatives were prepared from apovincaminic acid (4). In cerebral circulation, compound 5 (0.03-1.0 mg/kg iv) caused a dose-dependent increase in cerebral blood flow (CerBF) without affecting the blood pressure. It was more potent than vinpocetine (2). The structures of 2 and 5, determined by ...
