Synthesis and structure-activity relationships of 1-acyl-4-((2-methyl-3-pyridyl)cyanomethyl)piperazines as PAF antagonists
摘要:
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 a 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 acyl substituents 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 muM, HYP, ID50 = 0.021 mg/kg iv, MOR, ID50 = 0.30 mg/kg po) and 58 (UR- 12519, PAG IC50 = 0.041 muM, 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.

A series of novel 1,4-disubstitutedpiperidine/piperazine derivatives were designed, synthesized and evaluated for their in vitro activities against HIV-1 Bal (R5) infection in CEMX174 5.25M7 cells. A majority of these compounds showed potent anti-HIV-1 activities with IC at nanomolar levels. -(4-Fluoro-benzyl)piperazine analog hydrochloride exhibited potency against HIV-1 activity similar to that of
