  Synthesis and antibacterial activity of dual-action agents of a β-lactam antibiotic with cytotoxic agent mitozolomide or temozolomide

  摘要：

  Dual-action agents 5a-f and 12a-f. a beta-lactam antibiotic combined with a cytotoxic agent. mitozolomide (Meto) or temozolomide (Temo). were synthesised. The antibacterial activity (MICs) of the dual-action agents has been determined against a panel of bacteria including several beta-lactamase producing strains. The tests showed 5a-f active against the non-p-lactamase producing methicillin sensitive Staphylococcus aureus (MSSA) strains. however, little synergistic effect between the P-lactam and the cytotoxic agent was observed. 12a-f demonstrated some synergistic effect against bacteria. 12a. in particular. is active against ampicillin resistant (beta-lactamase-producing) strains of Serratia marcescens.

  The combined action of bases and acid anhydrides on 7-acylamidocephalosporanic acids, and the action of bases on their esters, set up equilibria in which the corresponding Δ2-isomers predominate. The isomerisation represents a prototropic shift probably favoured by the sulphur atom in the dihydrothiazine ring. The acetoxy-group in the Δ2-compounds can be replaced by nucleophiles.

  的碱和酸酐7-acylamidocephalosporanic酸的联合作用，以及碱基对它们的酯的动作，设置了其中相应Δ均衡2 -异构体占优势。异构化表示质子交换，这可能是二氢噻嗪环中的硫原子所促进的。的乙酰氧基团在Δ 2 -化合物可以通过亲核试剂代替。
