Substituted Amides and Hydrazides of Dicarboxylic Acids. Part 11.1 Synthesis and Pharmacological Activity of a Series of Pyridylamides of Dicarboxylic Acids
Previously [1, 2], we have found compounds producing a hypertensive effect in pyridylamides of some dicarboxylic acids. Below we report on the synthesis of a series of new pyridylamides of succinic (Ia–IIIa), maleic (Ib–IIIb), and phthalic (Ic–IIIc) acids and attempts at establishing a relationship between the hypertensive activity and structure of these compounds.
