Description
Curator's Comment: The description was created based on several sources, including https://clinicaltrials.gov/ct2/show/NCT01851369 | https://www.ncbi.nlm.nih.gov/pubmed/29108368 | https://clinicaltrials.gov/ct2/show/NCT02395692 | https://www.ncbi.nlm.nih.gov/pubmed/28670521

Methoxyamine (TRC102) is an orally bioavailable small molecule with potential adjuvant activity, that may potentiate the antitumor activity of alkylating agents. Methoxyamine covalently binds to apurinic/apyrimidinic (AP) DNA damage sites and inhibits base excision repair (BER) that causes topoisomerase II-dependent irreversible strand breaks and apoptosis. Methoxyamine is currently being studied in multiple Phase 1 and Phase 2 clinical trials sponsored by the National Cancer Institute or Case Comprehensive Cancer Center.

Sample Use Guides

Twenty-eight patients were treated with TRC102 at 15, 30, 60 or 100 mg/m2/d. The MTD was exceeded at 100 mg/m2/d due to grade 3 anemia in 50 % of patients.
Route of Administration: Oral
The human colorectal cancer cell line, HT29 were used for activity evaluation. HT29 cells were cultured at a density of 2×104 per well in multiwell plates (24 wells/plate, SPL). After 24 hours, we treated the cells with different concentrations of 5-FU (5-Fluorouracil) (0, 1, 5, 10, 50, 100 µM) or Mx (Methoxyamine) (0, 1, 6, 30, 60, 120 mM). After 24 hours, cell viability was determined by the trypan blue dye exclusion assay.
