| Summary: | Six new 2-halobenzoylthiourea compounds bearing α- and β-alanine have been successfully synthesized and characterized using CHNS microelemental analysis and spectroscopic methods including FTIR, UV-Vis and NMR. Microelemental analysis data of the compounds were in agreement with the theoretical values. The FTIR spectra showed the presence of important bands of the compounds while the 1 H-NMR and 13C-NMR exhibited the expected chemical shifts. The compounds exerted weak antioxidant activity in DPPH scavenging test and moderate to good activity in β-carotene bleaching test. The inclusion of halogen atoms has facilitated the released of hydrogen atoms and introduction of α- and β-alanine have increased the β-carotene bleaching and DPPH scavenging activities of the compounds. |
