标题:Synthesis And Biological Activity Of 5-Amino-And 5-Hydroxyquinolones,And The Overwhelming Influence Of The Remote N1-Substituent In Determining The Structure-Activity Relationship
摘要:A Series Of 5-Amino-And 5-Hydroxyquinolone Antibacterials Substituted At C7 With A Select Group Of Common Piperazinyl And 3-Aminopyrrolidinyl Side Chains Was Prepared. These 5-Substituted Derivatives Were Compared To The Analogous 5-Hydrogen Compounds For Antiinfective Activity By Using Dna Gyrase Inhibition,Minimum Inhibitory Concentrations Against A Variety Of Bacteria,And In Vivo Efficacy In The Mouse Infection Model. The Influence On The Structure-Activity Relationships Of Varied Substituents At C8 (H,F,Cl) And Ni (Ethyl,Cyclopropyl,Difluorophenyl) Was Also Studied. The Results Showed That Several Of The Structure-Activity Conclusions Regarding Side-Chain Bulk At C7,The Effect Of Halogen At C8,And The Effect Of The C5-Amino Group Were Greatly Influenced By The Choice Of The N1-Substituent. Several Outstanding Broad Spectrum Quinolones Were Identified In This Work. In Particular,The Spectrum And Potency Of The 7-Piperazinyl Quinolones Could Be Greatly Enhanced By The Judicious Choice Of C5-,C8-,And N1-Substitutents.
