  • New benzo [d] thiazole derivatives, process for their preparation and their therapeutic applications
    Patent number: 4208420
    Abstract: This invention relates to compounds having the general formula: ##STR1## and their pharmaceutically acceptable acid addition salts having the formula: ##STR2## in which: R represents hydrogen or a C.sub.1-4 alkyl radical,R' represents hydrogen or a C.sub.1-4 alkyl radical,m is 0, 1, 2 or 3,n is 3, 2, 1 or 0,the sum m+n being always equal to 3, andX.sup.- represents an anion formed by a pharmaceutically acceptable acid.Said compounds are typically useful as analgesic agents and as stimulants of the sympathetic nervous system, and also as central and peripheral vasoregulator agents.
