Abstract:
:A novel series of diphenyl lactam containing calcium channel blockers is described. Extensive SAR studies resulted in compounds with low molar activity and good plasma exposure after oral dosing. Compounds 2, 6 and 7 demonstrated significant efficacy in the capsaicin model of secondary hyperalgesia following oral administration.
