<p>Cephamycin compounds of the formula (I)
<Chemistry id="chema01" num="0001"><Image id="ia01" he="24" wi="125" file="IMGA0001.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>wherein R<Sup>1</Sup> represents hydroxyl or sulphooxy and R<Sup>2</Sup> represents sulphooxy together with derivatives thereof including salts, esters, N-protected derivatives and solvates thereof are disclosed. These compounds are of great value as intermediates in the preparation of other cephamycin compounds.</p><p>The compounds of the invention may be isolated from fermentation broths of strains of the genus Streptomyces which produce the compounds and a new such strain is described. The isolation of the compounds may be achieved by a liquid/liquid or liquid/solid ion-exchange technique, and is preferably achieved by the formation of an ion-pair in a liquid/liquid technique.</p> |
