The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 1-(Bis(4-chlorophenyl)methyl)piperazine( cas:27469-61-0 ) is researched.Name: 1-(Bis(4-chlorophenyl)methyl)piperazine.Yung, D. K.; Gilroy, M. L.; Mahony, D. E. published the article 《Synthesis and quantitative structure-activity relationships of antibacterial 1-(substituted benzhydryl)-4-(5-nitro-2-furfurylideneamino)piperazines》 about this compound( cas:27469-61-0 ) in Journal of Pharmaceutical Sciences. Keywords: piperazine benzhydryl nitrofurfurylideneamino; bactericide benzhydrylnitrofurylideneaminopiperazine; structure activity bactericide piperazine. Let’s learn more about this compound (cas:27469-61-0).
Twelve title compounds I (R = H, 4-Cl, 3-Me, 3,4-Cl2, etc., R1 = H, Cl, Me) were prepared by treating the corresponding benzhydryl chloride with piperazine followed by nitrosation, reduction, and condensation with 5-nitro-2-furancarboxaldehyde. I were examined for in vitro antimicrobial activity. The compounds were active against Bacillus cereus 7, Bacillus megaterium 122, Bacillus subtilis 104, Clostridium perfringens 13, and the tetracycline-resistant Clostridium perfringens 37. Regression analyses on the antibacterial activity data based on the Hansch approach, using π, π2, and σ parameters, yielded several statistically significant correlation equations. 1-Benzhydryl-4-(5-nitro-2-furfurylideneamino)piperazine stopped the protein and DNA syntheses in C. perfringens 13, as indicated by precipitable radioactivity. The compound, however, showed no effect on the cell wall synthesis in the bacteria.
Compounds in my other articles are similar to this one(1-(Bis(4-chlorophenyl)methyl)piperazine)Name: 1-(Bis(4-chlorophenyl)methyl)piperazine, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
