The dithiobisbenzamides 1–4 were synthesized using 2,2′-dithiosalicylic acid with ammonia/ethylamine/benzylamine and 1,2-diaminopropane under different reaction conditions such as grinding, microwave irradiation and conventional heating which yielded the same products but in different yields. The synthesized compounds were subjected to antibacterial screening against both Gram-Positive (S. aureus, B. cereus, E. faecalis) and Gram-Negative (E.coli, S.typhi, P.aeruginosa, Klebshiella pneumoniae, Shigella) bacteria. The acyclic amides 1–3 showed activity against gram-positive bacteria while no activity was observed for Gram-negative bacteria. On the other hand cyclic amide, 4 was completely inactive against both types of bacteria. The synthesised benzamides were also screened for their anti-HIV activity.
