Usage

Description

Flomox was launched in Japan as an orally active cephalosporin for respiratory and urinary tract infections, heptatic infections, ophthalmological and otorhinolarynological infections, skinkoft tissue infections, and for use in gynacology, dentistry and oral surgery. It can be prepared by condesation of 2(Z)-(2-(t-butoxycarbonylamino) thiazol-4-yl)-2-pentenoic acid with 7-amino-3-(carbanoyloxymethyl)- 3-cephem-4-carboxylic acid pivaloyl methyl ester followed by deprotection. Flomox is highly active against a wide variety of Gram-positive and Gram-negative bacteria, except for several strains such as Pseudomonas aeruginosa and enterococci, by acting as a cell wall synthesis inhibitor (β-lactamase stability against TEM-1 type β-lactamases) and is more effective than cefaclor and cefdinir. Absorption is improved by the pivaloyloxymethyl ester group which is easily lost by deesterification during GI absorption to produce the biologically active form. The pivalic acid generated quickly conjugates with carnitine and is excreted in the urine. The drop in plasma levels of carnitine was dose dependent and returned to normal levels upon termination of treatment.

A practical synthesis of cefcapene pivoxil

Cefcapene pivoxil monohydrochloride monohydrate, a broad spectrum third-generation cephalosporin for oral administration, was prepared by reacting three centers of 7-amino-3-(hydroxymethyl)cephalosporinic acid (7-HACA), derived from 7-aminocephalosporanic acid. The coupling of 7-HACA and (Z)-2-[2-(Boc-amino)thiazol-4-yl]pent-2-enoic acid, followed by carbamylation with chlorosulfonyl isocyanate, and precipitation with diisopropylamine gave the key intermediate, in which thiazole side chain and carbamoyl group had been introduced into the 7-amino and 3-hydroxymethyl groups of 7-HACA, respectively, in a continuous procedure. Afterwards, the intermediate was esterified with pivaloyloxymethyl iodide to complete the modification of the C4 carboxy group affording Boc-cefcapene pivoxil, from which the desired product was finally obtained by an economical Boc removal and successive formation of the hydrochloride in 36% overall yield on a decagram scale. This synthesis promises an easy entry to cefcapene pivoxil monohydrochloride monohydrate with convenient manipulation, simple isolation, and good yields; it is of potential value for production on an industrial scale.

Synthesis and structure-activity relationships of 7β-[(Z)-2-(2-aminothiazol-4-yl)-3-(substituted)-2- propenoyl-amino]-3-cephems with C-3 substitutions

Synthesis and biological activity of a series of 7β-[(Z)-2-(2-aminothiazol-4-yl)-3-(substituted)-2- propenoylamino]-3-cephem-4-carboxylic acids with C-3 substitutions and their pivaloyloxymethyl esters are described. These acid compounds exhibited potent antibacterial activity against both Gram-positive and Gram-negative bacteria. Pivaloyloxymethyl esters of selected compounds in this series were found to be well absorbed from small intestine in mice. Pivaloyloxymethyl 7β-[(Z)-2-(2-aminothiazol-4-yl)-2-pentenoylamino]-3- carbamoyloxymethyl-3-cephem-4-carboxyiate hydrochloride hydrate (S-1108) was finally selected as the candidate for clinical evaluation.
