Design, Synthesis of Analgesics and Anticancer of Some New Derivatives of Benzimidazole

Abstract

This work, contains some new compounds from benzimidazole derivatives, which are synthesized by condensation of Orthophenylene diamine and Carbon disulfide resulting in 2-Mercapto-benzimidazole which is treated by alcoholic potassium hydroxide forming potassium salt of 2-mercaptobenzimidazole which reacts with different substances (alkyl chloroacetates, chloroacetic chloride, alkyl halides) also the ethoxy carbonyl methyl thiobenzimidazole reacts with different amines. In addition to chloromethyl benzimidazole which resulted from the reaction between orthophenylene diamine and chloroacetic acid, which reacted with different amines. The synthesized compound tested as analgesics and anticancer activity the new derivatives revealed moderate, strong and very strong analgesics and moderate and strong anticancer activity.
