vivo Langendorff perfusedrat heart. Furthermore, the bioavailability and the antihypertensive properties of the most active derivative were evaluated by in vitro studies and in vivo administration (1month) on spontaneously hypertensive rats (SHRs), respectively. Among all studied Q1 derivatives, only the ethyl derivative reduced left ventricular pressure (at 10(-8)M/10(-6)M doses) and improved relaxation

Some penta-O-substituted analogues of quercetin were synthesized and tested for the inhibition of cytosolic and particulate rat brain cyclic AMP and cyclic GMP phosphodiesterase activities. Ten of these compounds are potent and highly selective inhibitors of cAMP hydrolysis with respect to cGMP hydrolysis. They inhibit more potently the particulate enzyme than the cytosolic preparation. The highest selectivity was observed with penta-O-ethylquercetin and analogue 6d, which proved to be more selective and more potent inhibitors than the reference compound Ro 20-1724. Some structure-activity relationships are discussed.
