TP-472 是一种选择性的BRD9/7抑制剂,对 BRD9 和 BRD7 作用的Kd值分别为 33 nM 和 340 nM。TP-472 对 BRD9 的选择性比 BRD7 以外的其他溴结构域家族成员高 30 倍以上。TP-472 诱导黑色素瘤细胞凋亡 (apoptosis)。
生物活性 | TP-472 is a selectiveBRD9/7inhibitor, withKds of 33 nM and 340 nM forBRD9andBRD7, respectively. TP-472 exhibits >30-fold selectivity forBRD9over other bromodomain family members exceptBRD7[1][2]. TP-472 inducesapoptosisof melanoma cells[3]. |

体外研究 (In Vitro) | TP-472 (1 μM, 3 μM; 24-216 hours) yields concentration-dependent growth defects in ESCs[2]. TP-472 (0.1-10 μM; 24 h) effectively inhibits the growth of both the BRAF mutant melanoma cell lines at 5 and 10 μM concentrations[3]. TP-472 (for 2 weeks) also strongly inhibits the long-term survival of multiple melanoma cell lines (M14, SKMEL-28, A375, and A2058) at concentrations of 5 and 10 μM[3]. TP-472 (5-10 μM; 24 h) treatment downregulates genes encoding various extracellular matrix (ECM) proteins, including integrins, collagens, and fibronectins in A375 cells[3]. TP-472 (0.1-10 μM; 24 h) results in the upregulation of pro-apoptotic genes (BAX, MDM2, CDKN1A) in A375 cells[3].
