  6-(1-hydroxyalkyl)penam sulfone derivatives as inhibitors of class a and class C β-lactamases I

  摘要：

  Five 6-(1-hydroxyalkyl)penam sulfone derivatives and two 6-(hydroxymethyl)penams were synthesized for beta-lactamase inhibitor screens. The substituent effects and stereochemical requirements of 6 alpha- and 6 beta-(1-hydroxyalkyl) groups for the biological activity of penam sulfone derivatives were investigated. Of these substituents, only the 6 beta-hydroxymethyl group of 15 improved the activity of sulbactam against both TEM-1 and AmpC beta-lactamases. The sulfone moiety is required for the enhancement of the beta-lactamase inhibitory activity. 6 beta-Hydroxymethylsulbactam (15) was able to restore the activity of piperacillin in vitro and in vivo against various beta-lactamase producing microorganisms.

  [reaction: see text] Diastereoselective reduction of 6-bromo-6-substituted penicillanate esters has been achieved by treatment with tributylphosphine to give 6-substituted penicillanate esters. This reaction would appear to proceed through a phosphonium beta-lactam enolate species, followed by a diastereoselective protonation. This method has the advantage of being simple to carry out and it is mild

  [反应：见正文]通过用三丁基膦处理得到6-取代的青霉酸酯，已经实现了6-溴-6-取代的青霉酸酯的非对映选择性还原。该反应似乎通过through-β-内酰胺烯醇化species物种进行，随后是非对映选择性质子化。该方法的优点是易于实施，并且温和，非对映选择性高，并且应能耐受底物中的许多官能团。这些意见的含义进行了讨论。

  Two stereoselective processes for the synthesis of novel 3,6-disubstituted penam sulfone derivatives were developed. One 6 beta-(l-hydroxyethyl) and four 6 beta-hydroxymethyl penam sulfone derivatives were synthesized. All four 6 beta-(hydroxymethyl)penam sulfone derivatives demonstrated good IC50 against both TEM-1 and AmpC beta-lactamases. of these, 6 beta-hydroxymethyl penam sulfone derivative 25 was the most active inhibitor which was able to restore the activity of piperacillin in vitro and in vivo against both TEM-1 and AmpC beta-lactamases producing organisms.
