A new pyrimidine based Schiff base ligand (HL) and its four complexes of type [MLOAc]·nH2O (Cu(II), 1; Zn(II), 2; Co(II), 3; and Ni(II), 4) have been synthesized and characterized by elemental analysis, MS, 1H-NMR, FT-IR, UV-visible, and ESR techniques. The electronic and ESR spectral data suggested that complexes 1–4 possess square planar geometry. Antimicrobial activities of HL and complexes 1–4 were tested against four bacteria (Staphylococcus aureus, Staphylococcus pneumonia, Salmonella enterica typhi, and Haemophilus influenzae) and two fungal strains (Aspergillus flavus and Aspergillus niger). These results show that complexes 1–4 have good antimicrobial activity compared to HL. The DNA cleavage activity of HL and complexes 1–4 was monitored by the agarose gel electrophoresis method. The antioxidant property of the prepared compounds was assessed by using 2,2′-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging method. DNA binding properties of HL and complexes 1–4 have been investigated by electronic absorption technique and viscometric measurements.

A series of quinazolines encompassed with thiazolidinone and azetidinone have been synthesized and evaluated for their antioxidant, anticancer and DNA binding studies. All the synthesized compounds were characterized by IR, 1H & 13C NMR and mass spectra. Antioxidant activity was carried out using % free radical scavenging by DPPH assay. Compounds 4b, 5b and 5d have shown better antioxidant activity (60, 67 and 66%, respectively) among the tested compounds. Compounds having % free radical scavenging activity more than 55% were evaluated for anticancer activity by MTT assay towards cell lines A-549 (lung carcinoma) and MDA-231 (human breast cancer). Results revealed that the tested compounds exhibited moderate to low anticancer activity. Further, DNA binding activity was studied by absorption titration method for all the synthesized compounds, and compound 5b showed a good binding constant of 70.05 and % hyperchromicity of 82.93%.
