摘要:The present invention discloses a macrolide compound or salt thereof, synthesis method, pharmaceutical composition, and application thereof. The present invention provides a method for preparing a macrolide compound 1, a macrolide compound 1', or a salt thereof; also provided are a macrolide compound 2, macrolide compound 2', or salt thereof, a pharmaceutical composition containing said compound or salt, and the application thereof in the preparation of a pharmaceutical for inhibiting methicillin-resistant Staphylococcus aureus. When one or more of the macrolide compound 2, the macrolide compound 2', the macrolide compound 2 salt, and the macrolide compound 2' salt of the present invention is used together with a β-lactam antibiotic, the inhibiting effect of the β-lactam antibiotic on methicillin-resistant Staphylococcus aureus is significantly increased. This is a new class of potentiator having a good potentiating effect in vitro, alleviating methicillin-resistant Staphylococcus aureus resistance to β-lactam antibiotics, and having good prospects for market development.

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.

摘要:A novel 4-halo-2-oxyimino-3-oxo butyric acid-N,N-dimethyl formiminium chloride chlorosulfate of formula (I) useful in the preparation of cephalosporin antibiotics n nwhereinn n X is chlorine or bromine; R is hydrogen, C 1-4 alkyl group, an easily removable hydroxyl protective group, —CH 2 COOR 5 , or —C(CH 3 ) 2 COOR 5 , wherein R 5 is hydrogen or an easily hydrolysable ester group. The compound of formula (I) is prepared by reacting 4-halo-2-oxyimino-3-oxobutyric acid of formula (IV 1 ), n nwherein X, R and R 5 are as defined above, with N,N-dimethylformiminium chloride chlorosulphate of formula (VII)n n nin an organic solvent at a temperature ranging from −30° C. to −15° C. The cephalosporins that may be prepared from the intermediate include cefdinir, cefditoren pivoxil, cefepime, cefetamet pivoxil, cefixime, cefmenoxime, cefodizime, cefoselis, cefotaxime, cefpirome, cefpodoxime proxetil, cefquinome, ceftazidime, cefteram pivoxil, ceftiofur, ceftizoxime, ceftriaxone and cefuzonam.
