Introduction of 27267-70-5 :

β-Rubromycin, a quinone antibacterial agent, is a selective HIV-1 reverse transcriptase inhibitor with a Ki of 0.27 μM. β-Rubromycin is a potent telomerase inhibitor with an IC50 of 3 μM. β-Rubromycin inhibits the proliferation of both K-562 and HeLa cells with IC50 values of 19.5 µM and 22.7 µM, respectively[1][2]. IC50 & Target:reverse transcriptase[1] In Vitro:β-Rubromycin inhibits equipotently HIV-1 RT and avian myeloblastosis virus RT, in a concentration-dependent manner, and is significantly weaker as an inhibitor of calf thymus DNA polymerase α[1].
A kinetic study of the inhibition by β-Rubromycin revealed a competitive interaction with respect to the telomerase substrate primer, with a Ki of 0.74 μM, whereas a mixed type inhibition was observed with respect to the nucleotide substrate[2].
