4-Thiothymidine
Based on 1 Customer Validation
4-Thiothymidine is a thymidine analog with UVA photosensitizing properties. 4-Thiothymidine incorporates into the DNA of dividing cells via the thymidine kinase-mediated salvage pathway, replacing thymine and sensitizing cells to UVA irradiation, thereby inducing apoptosis. 4-Thiothymidine induces DNA damage upon UVA activation and inhibits DNA replication. 4-Thiothymidine is used in research related to non-melanoma skin malignancies such as squamous cell carcinoma.

製品説明
体外実験
4-Thiothymidine treatment (combined with UVA irradiation) induces pan-nuclear γ-H2AX staining in HaCaT cells, indicating replication inhibition rather than discrete focal double-strand breaks[1].
4‑Thiothymidine exhibits extremely potent cytotoxicity toward HR‑deficient xrcc2 hamster cells and XPF‑deficient UV41 cells under 0.1 kJ/m2 UVA conditions. S5‑(6‑4) T:T photoproducts are removed via nucleotide excision repair in HaCaT cells; these photoproducts are completely irreparable in XPA‑deficient XP12RO cells and exhibit significantly reduced repair capacity in CCRF‑CEM leukemia cells[1].
4-Thiothymidine efficiently generates singlet oxygen in O2-saturated acetonitrile solution with a quantum yield of 0.42[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
