Synthesis and preliminary pharmacological evaluation of veratric acid ester 4-[ethyl-{2-(4-methoxyphenyl)-1-methylethyl} amino] butan-1-ol derivatives

Author(s): Nandini R. Pai and Deepnandan S. Dubhashi

In a quest of novel antispasmodic agents with antimicrobial properties, the present study describes design and synthesis of novel analogs for veratric acid ester 4-[ethyl-{2-(4- methoxyphenyl)-1-methylethyl} amino] butan-1-ol, an antispasmodic drug which is expected to be a potent antimicrobial agent may be due to the presence of two benzene rings and a secondary or tertiary nitrogen in the basic structural framework of the molecule. The reaction between substituted 2-ethylamino-1-(4’-methoxyphenyl) propane and various haloaryl benzoates derivatives obtained from reaction between different homologs of benzoic acid and dibromoalkanes in a two step process to give corresponding structurally diverse analogs of lead compound has been achieved. The structures of these novel analogs were confirmed by different structure elucidation techniques. All the compounds have been screened for their anti-spasmodic activity and the study extended further to evaluate their sedative, antibacterial and antifungal potency. The novel analogs of lead compound exhibited pronounced antispasmodic activities and also gave encouraging results of antimicrobial and sedative activity as anticipated.
