Abstract:
The activity of 2,2'-dicarbomethoxyamino-5,5'-dibenzimidazolyl ketone (II, C.D.R.I. Comp. 82/437) has been evaluated for its micro- and macro-filaricidal efficacy against Litomosoides carinii in rodents. A dose of 3 mg/kg (i.p.) and 50 mg/kg (oral) x 5 days of Comp. 82/437 was found to eliminate almost 100% of adult worms and microfilariae of L. carinii in cotton rat. It also killed 100% and 97% of adult worms and microfilariae of Dipetalonema viteae and Brugia malayi in Mastomys natalensis respectively, at 150 and 200 mg/kg x 5 days orally. The compound also exhibited marked chemoprophylactic and in vitro activity against L. carinii.
