Expansion of Antibacterial Spectrum of Muraymycins toward Pseudomonas aeruginosa
摘要:
It is urgent to develop novel anti-Pseudomonas agents that should also be active against multidrug resistant P. aeruginosa. Expanding the antibacterial spectrum of muraymycins toward P. aeruginosa was investigated by the systematic structure activity relationship study. It was revealed that two functional groups, a lipophilic side chain and a guanidino group, at the accessory moiety of muraymycins were important for the anti-Pseudomonas activity, and analogue 29 exhibited antibacterial activity against a range of P. aeruginosa strains with the minimum inhibitory concentration values of 4-8 mu g/mL.

structurally diverse saturated and unsaturated fattyacidconjugated ASOs with a range of hydrophobicity. The binding affinity of ASO fattyacidconjugates to plasma proteins improved with fattyacid chain length and highest binding affinity was observed with ASO conjugates containing fattyacid chain length from 16 to 22 carbons. The degree of unsaturation or conformation of double bond appears to have
