Synthesis and biological evaluation of novel T-type Ca2+ channel blockers
摘要:
A small molecule library of piperazinylalkylisoxazole derivatives containing about 600 compounds was designed, synthesized and evaluated for blocking effects on T-type Ca2+ channel. Several ligands were identified to possess high inhibitory activity against the T-type Ca2+ channel. The compound 21 with trifluoromethyl substituents at C-3-position of phenyl group (W) and C-2-position of phenyl group (R-2) showed the highest inhibitory activity with IC50 value of 1.02 muM, which is comparable to that of mibefradil.

N‐alkylation/N′‐arylation process in a multicomponent reaction with secondary amines, cyclic tertiary amines and electron‐deficient aryl halides has been described. In this case, the N‐alkylation of secondary amines, utilizing cyclic tertiary amines as alkyl group sources, is enabled by a facile C−N cleavage. Such an operationally simple method could facilitate access to aromatic aminoalkyl amines,

A series of N-(4-phenyl- and 4-pyridyl-1-piperazinylethyl)- and N-(4-phenyl-1-piperidinylethyl)-phthalmides were synthesized and tested for antipsychotic activity. All compounds suppressed the spontaneous motor activity and the apomorphine-induced climbing in mice and pergolide-induced locomotor activity in rats, demonstrating psychotropic properties equal to the corresponding properties of sulpiride
