A novel series of asymmetric 4-aryl-1,4-dihydropyridine (1,4-DHP) 3,5-diester derivatives and their symmetric analogues comprised of functional moieties of amlodipine, riodipine and cerebrocrast have been synthesized. The calcium channel blocking activity was evaluated in an isolated rat aortic ring model. The calcium overload preventing activity was tested in SH-SY5Y neuroblastoma cell line by a fluorescence-based calcium assay. Among synthesized and tested compounds, 4a showed the highest calcium overload preventing activity (IC50=39μM) and 7e demonstrated the highest calcium channel inhibiting activity (EC50=0.2 nM). Asymmetric ester 7a exerted both substantial calcium channel blocking and calcium overload preventing activity.
