A947 is a potent and selective SMARCA2 protein hydrolysis-targeted chimeric molecule (PROTAC) that induces the degradation of SMARCA2 by binding to VHL E3 ubiquitin ligase, with significant antitumor activity in vivo and in vitro, especially in SMARCA4-mutant non-small cell lung cancer (NSCLC) cells.

Description | A947 is a potent and selective SMARCA2 protein hydrolysis-targeted chimeric molecule (PROTAC) that induces the degradation of SMARCA2 by binding to VHL E3 ubiquitin ligase, with significant antitumor activity in vivo and in vitro, especially in SMARCA4-mutant non-small cell lung cancer (NSCLC) cells. |

In vitro | Methods: SW1573 cells were treated with A947 (500 nM) and quantitative diglycine residue analysis was performed by mass spectrometry to ensure maximal degradation of SMARCA2/4. Results: Ubiquitination of multiple lysines was observed on SMARCA2 and SMARCA4, with the strongest ubiquitination at K1450 mapping to the bromodomain of SMARCA2/4. This suggests that A947 is highly specific in degrading the intended target proteins at high concentrations. [1] |
In vivo | Methods: SMARCA4mut HCC515 xenograft mice were treated with A947 (40 mg/kg, intravenous injection, two weeks) to evaluate the pharmacodynamic (PD) effect. Results: A947 caused a rapid decrease in tumor SMARCA2 protein levels (96% reduction in 4 hours) and achieved the maximum reduction at 24 hours, indicating its anti-tumor activity. [1] |
