Application

BRACO19 hydrochloride has been used to study the role of antiviral activity of G4-stabilizing agents in cells infected with latent human immunodeficiency virus -1 (HIV-1).

Biochem/physiol Actions

BRACO19 is a telomerase inhibitor that stabilizes G-quadruplexes, targeting telomeric G-quadruplexes, inducing DNA damage and cell-cycle arrest.
Telomerase is associated with tumor progression and is highly expressed in a number of tumors. BRACO19 is known to prevent the capping and catalytic action of telomerase and thus, might serve as an effective therapeutic approach for cancer treatment. BRACO19 establishes antiviral activity against HIV (human immunodeficiency virus).

Telomeropathies are rare disorders associated with impaired telomere length control mechanisms that frequently result from genetic mutations in the telomerase complex. Dyskeratosis congenita is a congenital progressive telomeropathy in which mutation in the telomerase RNA component (TERC) impairs telomere maintenance
