📜6-氨基青霉烷酸,(2,3-二氢-1H-茚-5-基)苯基丙二酸氢酯 反应生成 卡茚西林 参考文献:Preparation,Hydrolysis,And Oral Absorption Of .Alpha.-Carboxy Esters Of Carbenicillin 标题:Preparation,Hydrolysis,And Oral Absorption Of .Alpha.-Carboxy Esters Of Carbenicillin 摘要:Twelve Alpha-Carboxy Esters Of Carbenicillin,A Parenteral Broad Spectrum Semisynthetic Penicillin,Were Synthesized And Examined As Potential Oral Carbenicillin Derivatives. The Rates At Which The Esters Were Hydrolyzed In Vitro To Carbenicillin By Animal And Human Tissues Were Compared And The Carbenicillin Serum Levels Arising After Oral Administration Of The Esters Were Measured In Squirrel Monkeys And Human Volunteer Subjects. The Alpha-Carboxyphenyl Ester Of Carbenicillin [carfecillin (British Pharmacopoeia Approved Name),Brl 3475] Was Selected For Further Study And Is Presently Undergoing Clinical Trial.

专利号:US-8017776-B2 优先权日:2003-07-15 标题 :Methods for synthesis of acyloxyalkyl compounds 发明人:BHAT LAXMINARAYAN; GALLOP MARK A 权利人:XENOPORT INC 摘要:Disclosed herein are methods for synthesizing 1-(acyloxy)-alkyl prodrug derivatives of drugs through oxidation of 1-acyl-alkyl derivatives of drugs under anhydrous reaction conditions. The methods typically proceed stereospecifically, in high yield, do not require the use of activated intermediates and/or toxic compounds and are readily amenable to scale-up.

The current invention also provides 1-acyl-alkyl derivatives of known drug components and methods for synthesizing these 1-acyl-alkyl derivatives.
专利号:US-2009111737-A1 优先权日:1999-05-24 标题:Novel antibacterial agents 发明人:CHRISTENSEN BURTON G; MORAN EDMUND J; GRIFFIN JOHN H; JUDICE J KEVIN; MU YONGQI; PACE JOHN L; MAMMEN MATHAI; AGGEN JAMES 权利人:CHRISTENSEN BURTON G; MORAN EDMUND J; GRIFFIN JOHN H; JUDICE J KEVIN; MU YONGQI; PACE JOHN L; MAMMEN MATHAI; AGGEN JAMES 摘要:This invention relates to novel multibinding compounds (agents) that are antibacterial agents. The multibinding compounds of the invention comprise from 2-10 ligands covalently connected by a linker or linkers, wherein each of said ligands in their monovalent (i.e., unlinked) state have the ability to bind to a an enzyme involved in cell wall biosynthesis and metabolism, a precursor used in the synthesis of the bacterial cell wall and/or the bacterial cell surface thereby interfere with the synthesis and/or metabolism of the cell wall. In particular the multibinding compounds of the invention comprise from 2-10 ligands covalently connected by a linker or linkers, wherein each of said ligands hasn a ligand domain capable of binding to penicillin binding proteins, a transpeptidase enzyme, a substrate of a transpeptidase enzyme, a beta-lactamase enzyme, pencillinase enzyme, cephalosporinase enzyme, a transglycoslase enzyme, or a transglycosylase enzyme substrate; Preferably, the ligands are selected from the beta lactam or glycopeptide class of antibacterial agents.
