AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
Thioguanine is an oral purine analog small molecule approved in 1966 for hematologic malignancies, primarily acute leukemias and chronic myeloid leukemia. It functions as a nucleotide antimetabolite, inhibiting purine synthesis and DNA replication in rapidly dividing cells. The drug is indicated for patients with leukemia who require cytotoxic chemotherapy.
