THE PRODUCTS HAVE PHARMACOLOGICAL PROPERTIES AND ARE USEFUL ANTI-ARRHYTHMIC AGENTS.
(R1,R2,R3-PHENYL)-(NH)N-C WHEREIN R1, R2 AND R3, WHICH MAY BE INDENTICAL TO OR DIFFERENT FROM EACH OTHER, ARE EACH HYDROGEN, FLUORINE, CHLORINE, BROMINE, ALKYL OF 1 TO 3 CARBON ATOMS, METHOXY, ETHOXY, CYANO OR TRIFLUOROMETHYL, Y IS OXYGEN OR SULFUR, AND N IS 1 OR 2, AND THEIR NON-TOXIC, PHARMACOLOGICALLY ACCEPTABLE ACID ADDITION SALTS; THE COMPOUNDS AS WELL AS THE SALTS ARE USEFUL AS ANALGESICS.
摘要:
The invention provides 3-oxo-2,3-dihydro-1,4-benzoxanines carrying a carbamoylakyl radical in the 4-position which have useful therapeutic properties as muscle relaxing agents, analgesics, anti-convulsion agents, anti-inflammatories, and anti-pyretics.
摘要:
6 - AMINOALKYL - 3 - OXO-2,3-DIHYDRO-1,4-BENZOXAZINES, WHICH MAY BE MADE BY REACTION OF A SECONDARY AMINE WITH A 6 - HALOALKYL - 3 - OXO-2,3-DIHYDRO-1,4-BENZOXAZINE, AND WHICH MAY BE USED AS CENTRAL NERVOUS DEPRESSANTS.
WHEREIN R1, R2, R3 AND R4 CAN BE HYDROGEN, HALOGEN, LOWER ALKYL OR LOWER ALKOXY AND ARE USEFUL EMPLOYED IN A DYE COMPOSITION FOR COLORING KERATINOUS FIBERS. SUCH COMPOSITIONS ARE AQUEOUS SOLUTIONS OF THE INDAMINES AND CAN BE FORMULATED WITH LOWER ALKANOLS AND FILM-FORMING COSMETIC RESINS TO PRODUCE HAIR SETTING LOTIONS.
