telomerase-in-2

Telomerase-IN-2 (Telomerase inhibitor 2) shows potent inhibitory activity against telomerase by decreasing the expression of dyskerin (IC50: 0.89 µM).

(-)-Epigallocatechin Gallate (EGCG) is a phenolic antioxidant polyphenol flavonoid found in plants such as green and black tea, which inhibits telomerase and DNA methyltransferase, blocks the activation of EGF receptors and HER-2 receptors, inhibits cellular oxidation, and prevents free radical damage to cells.

β-Rubromycin is a bacterial metabolite originally isolated from Streptomyces that has diverse biological activities.1 It inhibits the growth of HMO2, KATO-III, and MCF-7 cells with GI50 values of 0.5, 0.84, and <0.1 μM, respectively. β-rubromycin inhibits HIV-1 reverse transcriptase activity by 39.7% when used at a concentration of 10 μM. It also has antibacterial activity against Gram-positive bacteria. The structure of β-rubromycin was originally described as containing an ortho-quinone group, but it was revised to a para-quinone group in 2000 using organic and biosynthetic methods, as well as spectroscopic analysis.1,2,3References1.

Abacavir monosulfate is an orally active, competitive nucleoside reverse transcriptase inhibitor that effectively inhibits HIV replication. Additionally, it exhibits anticancer properties in prostate cancer cell lines, and has the ability to penetrate the blood-brain-barrier and suppress telomerase activity [1] [2] [3].
