                                    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 $\pm $ 0.51 $\mu $M, while its derivative  2,7-bis(butoxycarbonyl)-3,6-dichlorobenzo[1,2-$b$;6,5-$b$']dithiophene  (2) exhibited promising inhibition with IC$_50}$ = 263 $\pm $  0.32 $\mu $M. In the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging  assay, compound 2 exhibited promising activity with IC$_50}$ = 33  $\pm $ 0.42 $\mu $M, while compound 1 showed moderate inhibition in  the urease inhibition assay. Molecular docking studies determined the  possible interaction of benzodithiophene and alpha-glucosidase on the basis  of binding energy and scoring function. Structure-activity relationship  analysis revealed that compound 2,7-bis  (butoxycarbonyl)-3,6-dichlorobenzo[1,2-$b$;6,5-$b$'] dithiophene (1)  containing two chlorine substitutions exhibited more alpha-glucosidase  inhibition (IC$_50}$ = 263 $\pm $ .0.32 $\mu $M) than  other derivatives. Moreover, compound 2,7-bis  (butoxycarbonyl)-3,6-dichlorobenzo[1,2-$b$;6,5-$b$'] dithiophene (2)  with two chlorine substitutions exhibited potent DPPH radical scavenging  activity compared to other derivatives.
