Definitions related to thiotepa:
-
A polyfunctional, organophosphorus alkylating agent and a stable derivative of N,N',N''-triethylenephosphoramide (TEPA), with antineoplastic activity. Upon administration, thiotepa is converted into highly reactive ethylenimine groups, which covalently bind to nucleophilic groups in DNA and demonstrate a preference for the N7 position of guanine bases. This induces crosslinking of alkylated guanine bases in double-stranded DNA, interferes with both DNA replication and cell division, and results in both the induction of apoptosis and the inhibition of cell growth.NCI ThesaurusU.S. National Cancer Institute, 2021
-
A very toxic alkylating antineoplastic agent also used as an insect sterilant. It causes skin, gastrointestinal, CNS, and bone marrow damage.
