In this study, three substituted polyhalogenated nitrobutadiene derivatives were synthesized. Compound 1-[(2,3-dibromopropyl)sulfanyl]-1,3,4,4-tetrachloro-2-nitrobuta-1,3-diene (4) was synthesized before by our group. Compounds 8-{[1-[(2,3-dibromopropyl)sulfany]-3,4,4-trichloro-2-nitrobuta-1,3-butadien-1-yl}-1,4-dioxa-8-azaspiro[4.5]decane (5) and 1-[(2,3-dibromopropyl)sulfanyl]-3,4,4-trichloro-N-(4-methylpiperazin-1-yl)-2-nitrobuta-1,3-diene-1-amine (6) were synthesized in this work as original compounds. Xanthine oxidase, elastase inhibition abilities, and antioxidant activities were investigated in this work for compounds 4, 5, and 6. In this study, compounds 4, 5, and 6 exhibited antixanthine oxidase, antielastase, and antioxidant activities. Among the compounds screened, compound 4 exhibited xanthine oxidase and elastase inhibitor effect similar to the standard compound. Among the three tested compounds, compound 6 showed potent DPPH radical scavenging and reducing power activities. Therefore, these three compounds (4, 5, and 6) may be useful as an antixanthine oxidase, antielastase, and antioxidant agent in pharmaceutical and cosmetic industry.
