ISOXAZOLE DERIVATIVES AS CALCIUM CHANNEL BLOCKERS

Methods and compounds effective in ameliorating conditions characterized by unwanted calcium channel activity, particularly unwanted N-type or T-type calcium channel activity are disclosed. Specifically, a series of isoxazole containing compounds are disclosed of the general formula (1) where Z is N or CHNR3 and (Ar1)2CR4 is optionally substituted benzhydryl.

ORGANIC COMPOUNDS

The invention relates to novel diamines of the formula (I) in which all variables are as defined in the specification, in free base form or in acid addition salt form, to their preparation, to their use as medicaments and to medicaments comprising them.

HETEROCYCLIC AMIDE DERIVATIVES AS CALCIUM CHANNEL BLOCKERS

Methods and compounds effective in ameliorating conditions characterized by unwanted calcium channel activity, particularly unwanted N-type or T-type calcium channel activity are disclosed. Specifically, a series of heterocyclic amides are disclosed of the general formula (I) where Z is N or CHNR2 and X is NR2, O, S, S=O or SO2. Among other definitions for R, R1, W and Y, the compounds of formula (1) are further characterized by at least one of W or Y being CR3Ar2 where Ar is an aromatic or heteroaromatic ring (for example, where W or Y is a benzhydryl moiety).

Synthesis and Structure-Activity Relationships of 1-Acyl-4-(2-methyl-3-pyridyl)cyanomethyl)piperazines as PAF Antagonists

A second generation of (cyanomethyl)piperazines, 1-acyl-4-((2-methyl-3-pyridyl)cyanomethyl)piperazines, with increased oral activity was prepared and evaluated in vitro in PAF-induced platelet aggregation assay (PAG) and in vivo in a PAF-induced hypotension test in normotensive rats (HYP).Oral activity was ascertained through a PAF-induced mortality test in mice (MOR).Attachment of a methyl group at position 2 of our earlier pyridine derivatives resulted in an improvement of 1 order of magnitude or greater in the ID50 of the oral test.Three different types of acylsubstituents of similar potency emerge from this work: N-(diphenylmethylamino)acetyl, 3-substituted 3-hydroxy-3-phenylpropionyl, and N-substituted 3-amino-3-phenylpropionyl groups.The most interesting compounds, 26 (UR-12460, PAG IC50 = 0.040 μM, HYP, ID50 = 0.021 mg/kg iv, MOR, ID50 = 0.30 mg/kg po) and 58 (UR-12519, PAG IC50 = 0.041 μM, HYP, ID50 = 0.015 mg/kg iv, MOR, ID50 = 0.044 mg/kg po), compare favorably with WEB-2086.Compounds 26 and 58 were also tested in active anaphylactic shock (AAS) and endotoxin-induced mortality (EIM) tests.On the basis of these data, compounds 26 and 58 have been selected for further pharmacological development.
