Description

DERIVATIVES OF 3.3-BIARILPIPERIDINA AND 2,2-BIARILMORFOLINA BACKGROUND OF THE INVENTION This invention relates to 3,3-biarylpiperidine and 2,2-biarylmorpholine derivatives which have utility as ligands for opioid receptors. In the study of opioid biochemistry, a variety of endogenous opioid compounds and non-endogenous opioid compounds have been identified. This effort has led to significant research to understand the mechanism of action of the opioid drug, particularly in those that refer to opioid receptors of differentiated and cellular tissue. Opioid drugs are typically classified by their binding selectivity with respect to differentiated and cellular tissue receptors to which a specific drug species binds as a ligand. These receptors include mu (μ), delta (d) and kappa (K) receptors. At least three subtypes of opioid receptors are described (mu, delta, and kappa), and documented in the scientific literature. The three receptors are present in the central and peripheral nervous systems of many species, including man. The activation of delta receptors produces antinociception in rodents and can produce analgesia in humans, as well as influencing the mobility of the gastrointestinal tract.

(See Burks, T.F. (1995) in "The Pharmacology of Opioid Peptides," edited by Tseng, L.F., Harwood Academic Publishers).

Well-known narcotic opioids, such as morphine and its analogs, are selective for the mu opioid receptor. Mu receptors mediate analgesia, respiratory depression and inhibition of the gastrointestinal tract. Kappa receptors mediate analgesia and sedation. The existence of the delta opioid receptor is a relatively recent discovery that was a consequence of the isolation and characterization of endogenous enkephalin peptides, which are ligands for the delta receptor. Research over the past decade has produced significant information about the delta receptor, but a clear picture of its function has not yet emerged. The delta receptors mediate analgesia, but do not appear to inhibit intestinal passage in the characteristic form of mu receptors. The patent of E.U.A. 4,816,586, which was issued on March 28, 1989, of P.S. Portoghese, refers to various delta opioid receptor antagonists. These compounds are described as possessing a unique antagonist profile of the opioid receptor, and include compounds that are highly selective for the delta opioid receptor. The patent of E.U.A. 4,518,711, which was issued May 21, 1985, by V. J. Hruby et al., Describes cyclic analogues, conformationally of enkephalins. These compounds include both delta receptor agonists and antagonists, and are said to induce pharmacological and therapeutic effects such as analgesia in the case of agonist species of such compounds. It is suggested that the agonist species of the The compounds described are useful in the treatment of schizophrenia, Alzheimer's disease, and respiratory and cardiovascular functions. S. Goenechea, et al., In "Investigation of the Biotransformation of Meclozine in the Human Body", J. Clin. Chem. Clin. Biochem., 1988, 26 (2), 105-15, describes the oral administration of a polyarylpiperizine compound in a study of meclozine metabolism in human patients.

There is a continuing need in the art for improved opioid compounds, particularly compounds that are free from the addictive nature and other adverse side effects of conventional opiates such as morphine and fetidine.

The preparation of other compounds of formula I not specifically described in the above experimental section can be achieved using combinations of the reactions described above, which will be apparent to those skilled in the art. The compounds of formula I which are basic in nature, are capable of forming a wide variety of different salts with various inorganic and organic acids. The acids that can be used to prepare the pharmaceutically acceptable acid addition skids of the base compounds of this invention are those which form non-toxic acid addition salts, ie, salts containing pharmaceutically acceptable anions, such as the salts of hydrochloride, hydrobromide, hydroiodide, nitrate, sulfate or bisulfate, phosphate or acid phosphate, acetate, lactate, citrate or acid citrate, tartrate or bitartrate, succinate, maleate, fumarate, gluconate, saccharate, benzoate, methanesulfonate and pamoate [i.e. 1, 1'-methyl-bis- (2-hydroxy-3-naphthoate)]. Although such salts must be pharmaceutically acceptable for administration to animals, it is often desirable in practice to initially isolate a compound of formula I, from the reaction mixture, as a pharmaceutically unacceptable salt and then simply convert to the latter again to the free base compound by treatment with an alkaline reagent, and subsequently converting the free base to a pharmaceutically acceptable acid addition salt. The acid addition salts of the base compounds of this invention are readily prepared by treating the base compound with a substantially equivalent amount of the chosen mineral or organic acid in an aqueous solvent medium or in a suitable organic solvent such as metal or ethanol .

Such non-toxic base salts include those which are obtained from cations pharmaceutically acceptable such as sodium, potassium, calcium and magnesium, etc. These salts can be easily prepared by treating the corresponding acidic compounds with an aqueous solution containing the desired pharmaceutically acceptable cations, and then evaporating the resulting solution to dryness, preferably under reduced pressure. Alternatively, they can also be prepared by mixing together lower alkanolic solutions of the acidic compounds and the desired alkali metal alkoxide, and then evaporating the resulting solution to dryness in the same manner as before. In any case, stoichiometric amounts of the reagents are preferably employed in order to ensure completion of the reaction and maximum yield of the desired final product.

The tissues are suspended between platinum electrodes, attached to an isometric transducer with a voltage of 500 mg, and are stimulated with pulses of 0.03 Hz pulse width of 1 msec at the supraximal voltage. The IC2 values are determined by regression analysis of the response concentration curves for the inhibition of electrically induced contractions in the presence of 300 mM of the mu-selective CTOP antogonist. This test is a measure of d agonism. Myenteric guinea pig plexuses (Porcellus breed, male, 450-500 g, Dunkin Hartley) are suspended, with longitudinal muscle segments attached, in Kreb buffer with 1 g of tension, and stimulated with pulses of 0.1 Hz pulse width of 1 msec to the supra maximum voltage. The mu functional activity is determined in the presence of 10 nM nor-BNI with 1 μM of the mu selective agonist, DAMGO, added to the bath at the end of the experiment to define a maximum response. This test is an average of the mu agonist. Functional kappa activity is determined in the presence of 1 μM CTOP with 1 μM of the selective kappa agonist U-69.593 added at the end of the experiment, to define a maximum response. All inhibitions of the contraction height for the test compounds are expressed as a percentage of the inhibition otenida with the standard agonist, and the corresponding IC50 values are determined. The following procedure can be used to determine the activity of the therapeutic agents of this invention as agonists and as delta opioid receptor antagonists.
