摘要:
A hydrazine derivative of formula (I), ##STR1## wherein A represents an optionally substituted phenyl, naphthyl or heteroaromatic group containing one or two nitrogen atoms, and R.sup.1 represents hydrogen, optionally substituted alkyl, or optionally substituted benzyl, phenethyl, or 1-naphthylmethyl, or pyrid-3-ylmethyl group, and salts thereof, possess useful pharmaceutical properties.
摘要:
This invention relates to a thioformamide derivative of the formula I ##STR1## wherein: R and R.sup.1 each independently represent an alkyl group;A represents either:(1) a phenyl group which is optionally substituted; or(2) a heteroaromatic group (e.g. pyrid-3-yl, quinolin-3-yl); andY represents:an ethylene or methylene group or a direct bond.These compounds may be formulated as pharmaceutical preparations and have utility for the treatment of disorders associated with smooth muscle contraction.
