Cytosine yog ib qho tseem ceeb nruab nrab ntawm cov tshuaj zoo, tshuaj tua kab thiab tshuaj, thiab muaj ntau yam kev siv. Hauv thaj tsam ntawm cov tshuaj tua kab, ib qho tshuaj tua kab mob tshiab cytosine peptide tau tshawb pom thawj zaug. Nws yog ib tug dav-spectrum ua liaj ua teb tshuaj tua kab mob nrog high efficiency, tsis tshua muaj toxicity thiab tsawg residue. Hauv kev lag luam tshuaj, cytosine yog cov tshuaj nucleic acid uas tuaj yeem siv los ua tshuaj tiv thaiv kab mob. Nws yog tsuas yog siv los tsim cov tshuaj tiv thaiv kab mob AIDS thiab tshuaj tiv thaiv kab mob siab B tshuaj lamivudine, tshuaj tiv thaiv kab mob qog noj ntshav gemcitabine, thiab 5-flucytosine Pyrimidine thiab lwm yam.
