Emesis in mammals is prevented by administration of 3-alkoxy-thianaphthene-2-carboxamides in a daily dosage ranging from 50 to 500 .mu.g/kg as determined by a physician or veterinarian. When administered to dogs in a daily dosage of 250 .mu.g/kg, 100% protection is obtained against vomiting normally induced by subcutaneous administration of apomorphine.

Pharmacologically active 2-substituted-1,2,3,4,-6,7,12,12Aoctahydropyrazino(2'',1'':6,1)pyrido(3,4 -b)indoles corresponding to the formula
WHEREIN X is a straight or branched chain alkylene group optionally interrupted by a CO or a CHOH group, R is hydrogen, lower alkyl, aryl, aryloxy, cyano, carboxy, carbalkoxy, dialkylamino, benzodioxanyl or 4-pyridyl, and X and R together may be hydrogen; Y and Z independently are H2 or an oxygen atom; and R'' is hydrogen or a lower alkyl group. The compounds of the invention have tranquilizing and hypotensive activity. The inventive compounds are prepared by reacting an alkyl 1,2,3,4tetrahydro-9H-pyrido(3,4-b)indole-3-carboxylate starting material with ethyleneimine to give a 1-oxo-1,2,3,4,6,7,12,12aoctahydropyrazino(2'',1'':6,1)-pyrido(3,4-b)indole in which substituents are then introduced at position 2 by a variety of methods, before or after having hydrogenated the oxo group at position 1. Alternatively, an alkyl 2-chloro-acetyl-1,2,3,4tetrahydro-9H-pyrido(3,4-b)indole-3-carboxylate and a primary amine H2NXR are reacted to give a 1,4-dioxo-1,2,3,4,6,7,12,12aoctahydropyrazino(2'',1'':6,1)pyrido(3,4-b)indole, in which substituents are then introduced before or after having hydrogenated the two oxo groups at positions 1 and 4.
摘要:
WHEREIN A1, A2, A3, A4, A5 and B, taken separately, each represents hydrogen, halogen, halomethyl, alkyl, alkoxy, nitro, cyano or amino, and A5 and B, taken together, represent a bivalent radical selected from the group consisting of alkylene, alkenylene and alkadienylene having 3 to 5 carbon atoms and alkylene dioxy having 1 to 3 carbon atoms, said bivalent radical being connected to two adjacent carbon atoms of the benzene nucleus, WITH THE PROVISO THAT WHEN A1, A2, A3, A4, A5 and B are all hydrogen atoms, the diphenyl-methylene radical is in the ortho or meta position with regard to the nitrogen atom in the piperidine nucleus, AND THE ADDITION SALTS THEREOF WITH PHARMACEUTICALLY ACCEPTABLE INORGANIC OR ORGANIC ACIDS.
