BETd-246

CAS No. : 2140289-17-2

MCE 国际站：BETd-246

产品活性：BETd-246 是第二代、基于 PROTAC 技术的、 BET溴端结构域 (BRD) 的抑制剂，由Cereblon配体和BET配体相连，具有良好的选择性、有效性和抗肿瘤活性。

研究领域：PROTAC  |  Epigenetics

作用靶点：PROTACs  |  Epigenetic Reader Domain

In Vitro: BETd-246 treatment (0-100 nM, 1-3 h) causes a dose-dependent depletion of BRD2, BRD3 and BRD4 in representative TNBC cell lines with 30-100 nM for 1 h or with 10-30 nM for 3 h incubation.
BETd-246 (100 nM, 24/48 hours) displays strong growth inhibition and apoptosis induction activity in MDA-MB-468 cell lines. BETd-246 induces a rapid and time-dependent downregulation of MCL1 protein in all the TNBC cell lines evaluated. BETd-246 induces much stronger apoptosis than BETi-211.
BETd-246 (100 nM, 24 hours) induces pronounced cell cycle arrest and apoptosis in TNBC cell lines.

In Vivo: BETd-246 (5 mg/kg, IV, 3 times per week for 3 weeks) treatment effectively inhibits WHIM24 tumor growth, similar to the antitumor activity of BETi-211 with higher dosage and more frequently administration. The treatment of 10 mg/kg induces partial tumor regression during treatment without apparent toxicity. BETd-246 has very limited drug exposure in the xenograft tumor tissue in MDA-M-231and MDA-MB-468 models.
