In 2022,Lee, Yujeong; Onishi, Yoshiyuki; McPherson, Lisa; Kietrys, Anna M.; Hebenbrock, Marian; Jun, Yong Woong; Das, Ishani; Adimoolam, Shanthi; Ji, Debin; Mohsen, Michael G.; Ford, James M.; Kool, Eric T. published an article in ACS Chemical Biology. The title of the article was 《Enhancing Repair of Oxidative DNA Damage with Small-Molecule Activators of MTH1》.SDS of cas: 2510-22-7 The author mentioned the following in the article:
Here, it is reported that selected tyrosine kinase (TK) inhibitors including nilotinib, employed clin. in the treatment of chronic myeloid leukemia, are activators of the repair enzyme Human MutT Homolog 1 (MTH1). MTH1 cleanses the oxidatively damaged cellular nucleotide pool by hydrolyzing the oxidized nucleotide 8-oxo-2′-deoxyguanosine (8-oxo-dG)TP, which is a highly mutagenic lesion when incorporated into DNA. Structural optimization of analogs of TK inhibitors resulted in compounds such as SU0448, which induces 1000 +/- 100% activation of MTH1 at 10μM and 410 +/- 60% at 5μM. The compounds are found to increase the activity of the endogenous enzyme, and at least one (SU0448) decreases levels of 8-oxo-dG in cellular DNA. The results suggest the possibility of using MTH1 activators to decrease the frequency of mutagenic nucleotides entering DNA, which may be a promising strategy to suppress tumorigenesis in individuals with elevated cancer risks. The experimental process involved the reaction of 4-Ethynylpyridine(cas: 2510-22-7SDS of cas: 2510-22-7)
4-Ethynylpyridine(cas: 2510-22-7) belongs to pyridine. Pyridines form stable salts with strong acids. Pyridine itself is often used to neutralize acid formed in a reaction and as a basic solvent. SDS of cas: 2510-22-7
