    • 1,234,359. Isonipecotic acid derivative. JANSSEN PHARMACEUTICA N.V. 31 Oct., 1969 [4 Nov., 1968], No. 53573/69. Heading C2C. The novel compound, 1 - (3 - cyano - 3,3- diphenylpropyl) - 4 - phenylisonipecotic acid, and its pharmaceutically acceptable acid addition salts, are prepared by hydrolysing a C 1-7 alkyl ester of said acid, and, if desired, converting the resulting acid into a pharmaceutically acceptable acid addition salt thereof. Pharmaceutical compositions having antidiarrheal and analgesic activity comprise the novel compound, or a pharmaceutically acceptable acid addition salt thereof, together with a pharmaceutical carrier. The compositions may be administered orally or parenterally, e.g. in the form of tablets, capsules, powders, suspensions, elixirs and solutions. Reference has been directed by the Comptroller to Specification 843,319.

    • 1,128,079. Cyclohexane derivatives. CIBA Ltd. 26 Sept., 1966 [29 Sept., 1965; 19 Aug., 1966], No. 42872/66. Heading C2C. Novel cyclohexane derivatives of the formula wherein X is an alkylene radical optionally interrupted by an oxygen atom, Ph is a phenyl radical which may be substituted by C 1-7 alkyl, hydroxyl, C 1-7 alkoxy ortrifluoromethyl radicals or by halogen atoms, and R is a cyano or carbalkoxy radical, and acid addition salts thereof are prepared (1) by condensing heterocyclic bases XN-H with the appropriate cyclohexanones R.PhC 6 H 8 O and reducing the cyclohexene derivatives RPhC 6 H 7 NX produced, (2) by reacting the bases XN-H with cyclohexane derivatives of the formula B.Ph.C 6 H 9 Z, where Z is a halogen atom or an arylsulphonyloxy radical, or (3) when R is carbalkoxy, by interconverting the corresponding cyano compound, e.g. by alcoholysis in the presence of sulphuric acid and ammonium chloride or by hydrolysing the cyano group to the carbamoyl group and hydrolysing the 1 -heterocyclyl - 4 - phenyl - 4 - carbamoyl-cyclohexanes produced to the corresponding 1 - heterocyclyl - 4 - phenyl - 4 - carboxycyclohexanes and esterifying these, e.g. with diazoalkanes, and, if desired, converting the free bases produced to the corresponding acid addition salts with inorganic or organic acids. The products of these processes may be cis- or (rans-forms or mixtures thereof, in which case the individual isomers may be isolated by conventional procedures, e.g. chromatography or fractional crystallization. 1 - Cyano - 1 - phenyl - 4 - (p - toluene - sulphonyloxy) - cyclohexane used as a starting material is prepared by reducing 4-cyano-4-phenylcyclohexanone with hydrogen or sodium borohydride and treating the 4-cyano-4-phenylcyclohexanol produced with p-toluenesulphonyl chloride. Therapeutic compositions useful as antitussives or analgesics contain compounds of the above formula or physiologically tolerable acid addition salts thereof, as active ingredient. The composition may be in a form suitable for enteral, parenteral or topical application.
