α-Rubromycin

Name: α-Rubromycin
Brand: MedChemExpress
SKU: HY-119787
Availability: PreOrder

(Synonyms: Collinomycin)

α-Rubromycin (Collinomycin) is an antibiotic isolated from the mycelia of Streptomyces collinus. α-Rubromycin also acts as a DNA polymerase inhibitor, with an IC₅₀ of 0.91 μM against bovine mammalian DNA polymerase. α-Rubromycin binds to the active region of DNA polymerase β, competes with nucleotide substrates for binding, and interferes with template-DNA interactions. α-Rubromycin inhibits the activities of telomerase, retroviral reverse transcriptase and terminal deoxynucleotidyl transferase, as well as the growth of Staphylococcus aureus. α-Rubromycin can be used in studies related to bacterial infections.

In Vitro

α-Rubromycin potently and selectively inhibits mammalian DNA polymerase α and β, with the strongest inhibitory effect on rat DNA polymerase β (IC₅₀ = 0.45 μM). Its mechanism of action involves binding to the 31 kDa catalytic domain and competing with nucleotide substrates for binding, while it does not interfere with the binding of DNA templates^[1].
α-Rubromycin (compound 1) inhibits M-MLV RT with an IC₅₀ of 7.34 μM; it shows almost no activity against human immunodeficiency virus type 1 (HIV-1) reverse transcriptase, with an IC₅₀ > 200 μM; it also exhibits extremely weak inhibitory effect on human telomerase, with an IC₅₀ > 200 μM^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
