Synthesis, Evaluation of anticancer and antimicrobial activities of some Schiff bases derivatives

Abstract

      In this research, compound [1,2-Bis-(4-amino-5-mercapto-4H-[1,2,4]triazol-3-yl)-ethane-1,2-diol] was used as starting material for synthesis different Schiff's Bases compounds. The fusion of tartaric acid with thiocarbohydrazide produce the compound (C1), the Schiff's bases (C2-C4) were created through the condensation of substances (C1) with different substituted benzaldehydes in presence of glacial acetic acid as catalyst. Thin layer chromatography (TLC) was used to confirm the compounds' purity, and spectroscopic methods were used to infer the compounds' structures (FTIR) and magnetic nuclear resonance spectroscopy (1H-NMR and 13C-NMR). The agar well diffusion method was used to test synthesized compounds for their antibacterial activity against K. pneumonia and S. aureus, and the findings were inconsistent. Target substances were tested for their ability to kill human breast cancer at concentrations of 50 and 100 g/mL. Human muscle tissue HC normal cell line, human cervical cancer Hela cell line, and HePG2 cell line. The results showed that the chemicals had potential cytotoxic activity against the Hela cell line, particularly compound (C4), which had the greatest inhibition at doses of 100 mg/mL among the examined substances
