Synthesis and Biological Evaluation of Some New Thioether-Ester Crown Ethers
摘要:
New thioether-ester crown ethers have been synthesized starting from oxalyl chloride and different beta,beta'-dihydroxydithioethers. The synthesized compounds are screened for their antibacterial activity. Among the macrocyclic thioetheresters (5a-j), only 5,12-di[(allyloxy)methyl]-1,4-dioxa-7,10-dithiacyclododecane2,3-dione (5e) and 5,12-di(isopropoxymethyl)-1,4-dioxa-7,10-dithiacyclododecane2,3-dione (5)9 were effective inhibitors against Staphilococcus aureus methicillin resistance and Pseudomanas aeruginosa with an MIC value of 525 and 265 mu M. Structures of the synthesized compounds have been confirmed by H-1 NMR, C-13 NMR, and MS spectral studies.
