Sulfonamidine is disclosed of the general formula (I): R--NH--CH.dbd.N--SO.sub.2 --R.sub.1 (I) wherein R is a group selected from 2-[[(5-methyl-1H-imidazole-4-yl)methyl]thio]ethyl], 2-[[[5-[(dimethylamino)methyl]-2-furanyl]methyl]thio]ethyl, 2-[[[2-[(aminoiminomethyl)amino]-4-thiazolyl]methyl]thio]ethyl] or 3-[3-(1-piperidinylmethyl)phenoxy] propyl and R.sub.1 is alkyl; or a phenyl group optionally substituted by alkyl, halogen, nitro, alkoxy, alkanoylamino, carboxylic acid, alkoxycarbonyl, dialkylamino, alkylsulphonyl, alkylsulphonylamino or alkylthio; or 1,3,4-thiadiazole-2-yl substituted by alkanoylamino, and the pharmaceutically acceptable salts thereof, as well as a process for preparing these compounds and pharmaceutical compositions containing the same. These compounds have antiulcer activity and can be used in the treatment of peptic ulcers and other pathologies caused or stimulated by gastric acidity.
A colorless liquid crystalline compound having at least one 6-membered ring and non-cyclic end groups in the molecular skeleton, said 6-membered ring containing two or more carbon atoms, at least one of which is directly bonded to a methylene group of a non-cyclic group having an alkoxy group at another end has a wide mesomorphic range. When said colorless liquid crystalline compound is mixed with a liquid crystal composition, the resulting mixture also has an enlarged mesomorphic range and in almost all cases has a reduced viscosity.
The present invention relates to heteroaromate OSC inhibitors. The compounds are useful for the treatment and/or prophylaxis of diseases which are associated with 2,3-oxidosqualene-lanosterol cyclase such as hypercholesterolemia, hyperlipemia, arteriosclerosis, vascular diseases, mycoses, gallstones, tumors and/or hyperproliferative disorders, and treatment and/or prophylaxis of impaired glucose tolerance and diabetes.
