Cov tshuaj tua kab mob, tseem hu ua cov tshuaj tua kab mob, xa mus rau cov chav kawm ntawm cov metabolites thib ob uas tsim los ntawm cov kab mob (xws li cov kab mob, fungi, actinomycetes) lossis cov tsiaj siab dua thiab cov nroj tsuag hauv lawv lub neej txhua hnub, uas muaj cov tshuaj tiv thaiv kab mob lossis lwm yam dej num thiab tuaj yeem cuam tshuam kev loj hlob thiab kev ua haujlwm. ntawm lwm cov cell muaj sia. Cov tshuaj tua kab mob uas nquag siv hauv kev kho mob suav nrog cov tshuaj tua kab mob microbial kab lis kev cai xov xwm thiab cov khoom sib txuas ua ke los yog semi synthesized los ntawm cov txheej txheem tshuaj.
Cov tshuaj tua kab mob los yog cov kab mob bactericidal ntawm cov tshuaj tua kab mob thiab lwm cov tshuaj tua kab mob feem ntau yog tsom rau cov txheej txheem ntawm kev tua kab mob uas tib neeg (los yog lwm yam tsiaj thiab nroj tsuag) tsis muaj, suav nrog plaub lub luag haujlwm tseem ceeb ntawm kev ua: inhibiting kab mob cell phab ntsa synthesis, txhim kho cov kab mob cell membrane permeability, cuam tshuam nrog cov kab mob protein synthesis, thiab inhibiting kab mob nucleic acid replication thiab transcription.
Nrog rau qhov tshwm sim ntawm cov tshuaj tua kab mob qog nqaij hlav, nws qhia tau hais tias cov tshuaj uas tsim los ntawm cov kab mob tsis yog tsuas yog muaj kev ua haujlwm ntawm inhibiting lossis tua cov kab mob pathogenic, tab sis kuj muaj cov haujlwm ntawm inhibiting kev loj hlob lossis metabolism ntawm cov qog nqaij hlav cancer. Yog li, niaj hnub txhais ntawm cov tshuaj tua kab mob yuav tsum yog: cov khoom tsim los ntawm qee cov kab mob uas tuaj yeem cuam tshuam kev loj hlob ntawm cov kab mob thiab lwm cov hlwb.
