2,4-Diamino-6,7-dimethoxyquinazolines. 3. 2-(4-Heterocyclylpiperazin-1-yl) derivatives as alpha 1-adrenoceptor antagonists and antihypertensive agents.
J. Med. Chem. 30(10) , 1794-8, (1987) A series of 4-amino-6,7-dimethoxy-2(4-heterocyclylpiperazin-1-yl)quinazolines (3) was prepared and screened for alpha-adrenoceptor affinity and antihypertensive activity. These quinazoline derivatives showed high binding affinity (ca. 10(-10) M) and selectivi... |
