Morpholine derivatives of the formula: ##STR1## in which Z is CH or N, Y is hydrogen, halogen, alkyl of 1 to 4 carbon atoms, or alkoxy of 1 to 4 carbon atoms, R is hydrogen, alkyl of 1 to 4 carbon atoms, alkenyl of 2 to 4 carbon atoms, benzyl, or phenyl, and R.sub.1 is hydrogen or benzyl, and their non-toxic pharmaceutically acceptable acid addition salts have interesting therapeutic properties, especially on the central nervous system.

Morpholine containing benzimidazoles

The invention provides novel hydrazine derivatives of the formula: ##STR1## in which R is a variously substituted oxy or thio substituted phenyl radical, 2-oxobenzimidazol-5-yl radical or 3-pyridyl radical;

Hydrazine derivatives useful as anti-hypertensives

This invention relates to substituted 1,4-dihydropyridines showing interesting physiological activities, particularly on the cardiovascular system. 1,4-Dihydropyridines in accordance with the invention are substituted in the 4-position by a 2-chloropyrid-3-yl or a 2-methylthiopyrid-3-yl group, in the 3- and 5-positions by a methoxycarbonyl or ethoxycarbonyl group and in the 2- and 6-positions by a methyl group. Acid addition salts of these compounds are included in the present invention. The compounds can be prepared by reacting an appropriate 2-substituted nicotinaldehyde with an alkyl acetoacetate. Compounds in accordance with the invention have shown anti-hypertensive activity at very low doses.
