Cefoxitin yog cov tshuaj tua kab mob ib nrab tau los ntawm Cephamycin C, muaj kev tiv thaiv siab rau β-lactamase inactivation. Ib qho tshuaj tua kab mob. Cefoxitin muaj tib lub C-7 sab saw li cephalothin thiab tib C-3 sab saw li cefuroxime. Cov tshuaj lom neeg tshiab tshaj plaws ntawm cefoxitin yog muaj cov pab pawg α-taw qhia methoxyl hloov chaw ntawm H-atom ntawm C-7. Qhov kev nce ntxiv ntawm cov kab mob no ua rau muaj kev ruaj ntseg tseem ceeb tiv thaiv β-lactamases. Kev tshoov siab rau cov pab pawg muaj txiaj ntsig no tau muab los ntawm kev tshawb pom qhov tshwm sim ntawm cov tshuaj tua kab mob cephamycin C tau los ntawm kev fermentation ntawm Streptomyces lactamdurans. Cephamycin C nws tus kheej tsis tau pom kev siv tshuaj kho mob tab sis, theej, tau muab cov txheej txheem txheej txheem uas coj mus rau cov neeg muaj txiaj ntsig zoo xws li cefoxitin. Cov neeg sawv cev uas muaj 7α pawg methoxy no feem ntau hu ua cephamycins. Kev hloov pauv tshuaj lom neeg tam sim no ua kom muaj kev qhia hluavtaws ntawm cov pab pawg methoxy rau hauv cephalosporins tsis muaj qhov tshwj xeeb no.
