Bleomycin A2
Based on 1 Customer Validation
Bleomycin A2 is an antitumor Antibiotic and also an aspartate/asparagine-β-hydroxylase (AspH) inhibitor with an IC50 of 1.47 μM. Bleomycin A2 inhibits the polynucleotide ligase reaction in E. coli B infected by T4 phage. Bleomycin A2 promotes DNA degradation, induces DNA strand breaks and regulates DNA polymerase activity. Bleomycin A2 can be used in research related to leukemia, head and neck cancer, and Ehrlich carcinoma.

Biological Activity
|
Glycopeptide |
Bleomycin A2 potently inhibits the catalytic activity of recombinant His6-AspH315-758 in SPE-MS analysis, with an IC50 of 1.47 μM, and its inhibitory potency is independent of increases in 2OG, Fe (II) or substrate concentration[1].
Bleomycin A2 (40 μg/mL; 30 min) inhibits DNA polymerase activity by 89% in crude extracts of E. coli B. This effect is reversible by divalent cations or EDTA, and Bleomycin A2 also stimulates DNase-mediated primer DNA degradation in the same system[3].
Bleomycin A2 (2-20 μg/mL; 120 min) stimulates pancreatic DNase-mediated degradation of salmon sperm DNA, with a stronger effect at higher concentrations[3].
Bleomycin A2 (0.1-30 μM; 1 h) reduces the clonogenic survival rate of L1210 cells in a concentration-dependent manner. Co-incubation with Lidocaine (HY-B0185) or immediate treatment with Lidocaine after exposure significantly enhances its cytotoxicity, and treatment with 10 μM Bleomycin A2 combined with 8 mM Lidocaine increases the cell killing rate by 1000-fold[2].
Bleomycin A2 (5-25 μM; 1 h) induces DNA strand breaks in L1210 cells in a concentration-dependent manner. Co-incubation with Lidocaine significantly enhances its DNA-damaging activity, and Lidocaine inhibits the repair of Bleomycin A2-induced DNA strand breaks, thereby further exacerbating the extent of strand breaks[2].
