In this study, the synthesis of some benzoxazoles and their analogues were described and their antiviral activities were studied together with the previously synthesized 2,5,6-trisubstituted benzoxazole, benzothiazole, benzimidazole and oxazolo(4,5-b)pyridine derivatives. The reverse transcriptase (RT) inhibitory activity of these compounds was determined using a commercial kit and assay system which utilizes the scintillation proximity assay principle. The results are concentration at which the compound inhibits RT activity by 50%). The compounds inhibited the in vitro binding of thymidine to the RT enzyme exhibiting IC50 values between 6.3 × 105 μmol/l-0.34 μmol/l and their activities were compared to some standard drugs such as 3′-azido-2′,3′-dideoxythymidine triphosphate and dideoxythymidine triphosphate.
