Braco-19 trihydrochloride
目录号 : KM8530 CAS No. : 1177798-88-7

Braco-19 trihydrochloride 是一种有效的端粒酶/端粒 (telomerase/telomere) 抑制剂,可防止端粒酶的催化作用。Braco-19 trihydrochloride 作为四联体 (GQ) 结合配体,稳定 GQ 四联体在 3V 端粒 DNA 处的形成,并可以导致快速衰老或选择性细胞死亡。Braco-19 trihydrochloride 也是一种HAdV病毒复制抑制剂。

生物活性

Braco-19 trihydrochloride is a potent telomerase/telomere inhibitor, preventing the capping and catalytic action of telomerase. Braco-19 acts as G-quadruplex (GQ) binding ligand, stabilizing G-quadruplexes formation at the 3V telomeric DNA overhang and produce rapid senescence or selective cell death. Braco-19 is also a HAdV virus replication inhibitor.

体外研究

Braco-19 trihydrochloride, as a well-known GQ binding ligand, interacts specifically with the HAdV GQs and increases their stability, and blocks the HAdV multiplication.
BRACO-19 trihydrochloride (1.0-10 μM; 5 day) cause zero growth inhibition is found 1 μM, the IC50 for BRACO-19 in UXF1138L cells is 2.5 μM, the IC100 is 5 μM.
BRACO-19 trihydrochloride (1 μM; 24 hours) shows dramatically reduced nuclear hTERT expression. However, residual cytoplasmic hTERT staining is observed accompanied by the occurrence of atypical mitoses.
BRACO-19 trihydrochloride (0-40 μM; 24 hours) decreases the AdV virus growth in a dose-dependent manner in eGFP-transinfected HEK 293 cells.
BRACO-19 trihydrochloride (0-150 μM; 24 hours) shows a decrease in band intensity in an increasing concentration-dependent manner.

Cell Viability Assay

Cell Line: HEK 293 cells
Concentration: 20 μM; 40 μM
Incubation Time: 24 hours
Result: Displayed low cytotoxicity and decreased the eGFP fluorescence.
体内研究

BRACO-19 trihydrochloride (oral administration or intraperitoneal injection; 2 or 5 mg/kg; 3 weeks) oral dosing regimen are always inactive and the animals have to be sacrificed due to high tumor burden before overall termination of the study, Chronic, i.p. BRACO-19 administration, qdx5 is efficient in inhibiting tumor growth in earlystage xenografts but not advanced-stage xenografts.
BRACO-19 trihydrochloride (intraperitoneal injection; 2 mg/kg; 3 weeks; starting 6 days after transplantation of UXF1138LX fragments) inhibits tumor growth significantly and under these conditions, marked single-agent antitumor activity is observed, with some animals in the group showing complete regressions (5 of 12 tumors).

Animal Model: Established UXF1138LX Xenografts in nude mice
Dosage: 2 mg/kg
Administration: Intraperitoneal injection; 3 weeks; starting 6 days after transplantation of UXF1138LX fragments
Result: Showed partial tumor regressions with an optimal T/C on day 28 of 4.1%, equal to 95.9% inhibition of tumor growth compared with control.

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
