Abstract

Two series of new hydrazones and 1,3-thiazolidin-4-ones incorporating furoxan moiety were synthesized from eugenol, the main component of Ocimum sanctum L. oil. The structure of these compounds was determined by IR, MS, 1H and 13C NMR analysis. All resonance signals of proton and carbon in the examined compounds are assigned using HSQC, HMBC and NOESY spectra. The hydrazones and the 1,3-thiazolidin-4-ones were tested for antimicrobial activities and almost all examined thiazolidinones displayed moderate activity against S. aureus and A. niger. Among screened hydrazones only one compound exhibited a significant cytotoxicity for human cancer cell line SW620.
