Substituted piperidine compounds represented by the structure I are provided, wherein each of Rla, R1b, R1c, R1d, Rle, R1f, R1g, R1h, R2, R2A, R3, R4, A, X, a, x, and n is as defined in the specification. Substituted piperidine compounds of structure I may permeate or penetrate across a nerve cell membrane into the interior of a nerve cell, may inhibit intracellular Rho kinase enzyme found in nerve cells in mammals, and may find utility in repair of damaged nerves in the central and peripheral nervous system of such mammals. These compounds may induce the regeneration or growth of neurites in mammalian nerve cells and may thereby induce regeneration of damaged or diseased nerve tissue. These compounds also find additional utility as antagonists of the enzyme Rho kinase in treatment of disease states in which Rho kinase is implicated. Pharmaceutical compositions containing these substituted piperidine compounds may be useful to promote neurite growth and in the treatment of diseases in which Rho kinase inhibition is indicated.

tautomers for Schiffbasesfrom gossypol, while their corresponding hydrazones only possess N-imine-N-imine structures both in solution and the solid state. The modification of interactions between the lone pairs on the nitrogen atoms by altering the steric hindrance of the non-iminic nitrogen can favor enamine tautomers. This assumption has now been confirmed and, in the solid state, hydrazones from N-aminopiperidine

The present invention relates to a cinchonidine salt of (4S,5S)-5-(4-chlorophenyl)-1-(2,4-dichlorophenyl)-4-methyl-4,5-dihydro-1H-pyrazole-3-carboxylic acid. This cinchonidine salt is prepared by enantiomeric resolution of a compound of formula (I) comprising:
the reaction of compound of formula (I) with cinchonidine in a suitable solvent, thereby resulting in the cinchonidine salt of the enantiomer (4S,5S) of formula (II); and optionally isolating said salt. The cinchonidine salt according to formula (II) is a useful intermediate in the preparation of a cannabinoid CB1 neutral antagonist.
