Benzodithiophenes are heterocyclic compounds that have various medicinal and industrial applications. In the present study, halobenzodithiophene, the simplest benzofused thiophene, and its derivatives were synthesized and evaluated against alpha-glucosidase, urease, and free radical production. In the alpha-glucosidase inhibition assay, compound 2,2-bisbenzothiophne (1) exhibited potent activity with IC 50 = 135 ± 0.51 µ M, while its derivative 2,7-bis(butoxycarbonyl)-3,6-dichlorobenzo[1,2b ;6,5b ']dithiophene (2) exhibited promising inhibition with IC 50 = 263 ± 0.32 µ M. In the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging assay, compound 2 exhibited promising activity with IC 50 = 33 ± 0.42 µ M, while compound 1 showed moderate inhibition in the urease inhibition assay. Molecular docking studies determined the possible interaction of benzodithiophene and alpha-glucosidase on the basis of binding energy and scoring function. Structure-activity relationship analysis revealed that compound 2,7-bis (butoxycarbonyl)-3,6-dichlorobenzo[1,2b ;6,5b '] dithiophene (2) containing two chlorine substitutions exhibited more alpha-glucosidase inhibition (IC 50 = 263 ± .0.32 µ M) than other derivatives. Moreover, compound 2,7-bis (butoxycarbonyl)-3,6-dichlorobenzo[1,2b ;6,5b '] dithiophene (2) with two chlorine substitutions exhibited potent DPPH radical scavenging activity compared to other derivatives.
