生物活性

Alobresib (GS-5829) is a BET bromodomain inhibitor, which represents a highly effective therapeutics agent against recurrent/chemotherapy resistant uterine serous carcinoma (USC) overexpressing c-Myc[1].

IC50 & Target

BET bromodomain[1]
体外研究
(In Vitro)

Alobresib (0.1 nM-100 μM; 72 hours) inhibits cell proliferation in primary uterine serous carcinoma (USC) lines[1].

上海金畔生物科技有限公司 has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Proliferation Assay[1]

Cell Line: Primary uterine serous carcinoma (USC) lines ARK1 and ARK2 cell lines
Concentration: 0.1 nM, 10 nM, 1 μM, 100 μM
Incubation Time: 72 hours
Result: A progressive, dose response decrease in cell proliferation. IC50s of 27 nM and 31 nM for ARK2 and ARK1 cells, respectively.

体内研究
(In Vivo)

Alobresib (10 and 20 mg/kg; oral; twice-daily; for 28 days) impaires USC-ARK2 xenograft tumor growth in female CB17/lcrHsd-Prkd/scid mice. Alobresib exhibits a significantly slower rate of tumor growth in mice, compared with vehicle control and to mice undergoing daily treatment with JQ1 (50 mg/kg/day i.p.)[1].
Alobresib (10 and 20 mg/kg; oral; twice-daily; for 28 days) is well tolerated with no clear impact on body weight compared with vehicle control[1].

Animal Model: Female CB17/lcrHsd-Prkd/scid mice (15-19 g) bearing USC-ARK2 tumors[1]
Dosage: 10 and 20 mg/kg
Administration: Oral; twice-daily; 28 days
Result: Exhibited a significantly slower rate of tumor growth, compared with vehicle control and to mice undergoing daily treatment with JQ1 (50 mg/kg/day i.p.).
