5-Acetylamino-6-formylamino-3-methyluracil is believed to function by inhibiting the enzyme dihydropyrimidine dehydrogenase (DPD). DPD is responsible for breaking down the nucleoside thymidine. By inhibiting DPD, 5-Acetylamino-6-formylamino-3-methyluracil prevents the breakdown of thymidine, leading to increased levels of thymidine within the cell. This increase in thymidine levels is thought to be the cause of the therapeutic effects of 5-Acetylamino-6-formylamino-3-methyluracil.
