4-Amino-4-phenylcyclohexanone ketal compositions and process of use

A class of new 4-amino-4-arylcyclohexanones, their ketals, and acid addition salts have been synthesized and found to be useful for relieving pain in animals. Their analgesic activity appears to be of high order, and in addition some exhibit narcotic antagonist activity that is useful in modifying the cardiovascular, respiratory, and behavioral depression caused by other analgesics. Several show mixed analgesic and narcotic antagonist activity. Preferred compounds of the class are 4-(m-hydroxyphenyl)-4-dimethylaminocyclohexanone ethylene ketal, and 4-(m-hydroxyphenyl)-4-(n-butylmethylamino)cyclohexanone ethylene ketal as free bases and as their hydrochloride salts. Processes for synthesis and intermediates are described. Unit dosage forms and therapeutic treatments are disclosed.

4-Arylcyclohexylamines

The invention relates to novel 4-hydroxymethyl(acyloxymethyl and methyl)-4-arylcyclohexylamines embraced by the formula SPC1 Wherein Ar is an aromatic ring selected from the group consisting of phenyl and naphthyl, each of which has from zero through three substituents independently selected from the group consisting of fluorine, chlorine, bromine, lower alkyl of one through three carbon atoms, lower alkoxy of one through three carbon atoms, and lower alkylthio of one through three carbon atoms; Z is selected from the group consisting of hydrogen, hydroxy and lower acyloxy of one through four carbon atoms; ? is a generic expression denoting cis and trans stereoconfiguration and mixtures thereof, with the proviso that when the stereoconfiguration of the linkage connecting the cyclohexane ring and CH2 Z is cis to the amino group, the linkage connecting the cyclohexane and Ar rings is trans, and vice versa; R1 is selected from the group consisting of hydrogen and lower alkyl of one through three carbon atoms; R2 is selected from the group consisting of hydrogen, lower alkyl of one through three carbon atoms, EQU1 WHEREIN N IS 2 THROUGH 5 AND Ar has the same meaning as above; R1 and R2 taken together with --N is a saturated heterocyclic amino radical selected from the group consisting of unsubstituted and substituted pyrrolidino, piperidino, hexamethylenimino, morpholino and piperazino; and pharmacologically acceptable acid addition salts thereof. It also relates to intermediates and processes for the preparation of the aforesaid novel compounds (I) and novel derivatives thereof. The administration to humans and animals of the novel compounds (I) depresses their central nervous systems and lowers their blood pressures.

Benzospiran derivatives

This invention relates to novel benzospiran derivatives embraced by the formula SPC1 Wherein the sum of A and B is at least the integer 2; A is selected from the group consisting of --(CH2)n -- wherein n is 1 through 5 and --(Cn H2n --2 XY)-- wherein X is selected from the group consisting of hydroxy, acetoxy, amino and acetamido and Y is hydrogen, and X when taken together with Y is selected from the group consisting of =O and =CR3 R4 wherein R3 and R4 are selected from the group consisting of hydrogen and lower alkyl of 1 through 3 carbon atoms; B is absent or --(CH2)n -- wherein n is 1 through 3; R1 is selected from the group consisting of hydrogen and lower alkyl of 1 through 3 carbon atoms; R2 is selected from the group consisting of hydrogen, lower alkyl of 1 through 3 carbon atoms, EQU1 WHEREIN N IS 2 THROUGH 5 AND Ar is phenyl having zero through three substituents selected from the group consisting of lower alkyl of 1 through 3 carbon atoms, lower alkoxy of 1 through 3 carbon atoms, bromine, chlorine and fluorine; R1 and R2 taken together with --N is a saturated heterocyclic amino radical selected from the group consisting of unsubstituted and substituted pyrrolidino, piperidino, and hexamethylenimino; Z is selected from the group consisting of hydrogen, lower alkyl of 1 through 3 carbon atoms, lower alkoxy of 1 through 3 carbon atoms, nitro, amino, monoalkylamino of 1 through 3 carbon atoms, acylamido of 1 through 4 carbon atoms, bromine, chlorine and fluorine; and a pharmacologically acceptable acid addition salt thereof. It also relates to intermediates and processes for the preparation of the aforesaid novel compounds (1) and novel derivatives thereof. The administration to humans and animals of the novel compounds (1) depresses their central nervous systems and lowers their blood pressures.

Butyrophenones as hypotensive agents. Derivatives of 4 aryl 4 (hydroxymethyl)cyclohexylamine

The preparation of butyrophenone derivatives of 4 aryl 4 (hydroxymethyl) cyclohex 1 ylamines starting from the corresponding 4 cyano 4 phenylcyclohexan 1 ones is described. Substitution was varied in both rings; both isomers of 4 phenyl 4 (hydroxymethyl)cyclohex 1 ylamine were characterized. Those derivatives which carried p fluoro substitution on the butyrophenone exhibited hypotensive activity in the rat with diminished CNS activity compared to compounds lacking the hydroxymethyl group. The effect of substitution on the 4 aryl ring is discussed.
