BSJ-4-116
目录号 : KM8188 CAS No. : 2519823-34-6 纯度 : 98%

BSJ-4-116 是由 Cereblon 配体和 CDK 配体相连的 PROTAC。BSJ-4-116 是一种高效且选择性的 CDK12 降解剂,IC50 为 6 nM。BSJ-4-116 通过提前终止转录来下调 DDR 基因,主要是通过增加聚腺苷酸化。BSJ-4-116 单独或与聚(ADP-核糖)聚合酶抑制剂 Olaparib 联合使用时表现出有效的抗增殖作用。

生物活性

BSJ-4-116 is a PROTAC connected by ligands for Cereblon and CDK. BSJ-4-116 is a highly potent and selective CDK12 degrader (PROTAC) with an IC50 of 6 nM. BSJ-4-116 downregulates DDR genes through a premature termination of transcription, primarily through increasing poly(adenylation). BSJ-4-116 exhibits potent antiproliferative effects, alone and in combination with the poly(ADP-ribose) polymerase inhibitor Olaparib .

体外研究

BSJ-4-116 (10-10000 nM; 72 hours) exhibits potent antiproliferative effects in Kelly CDK12.
BSJ-4-116 (50 nM; 6-24 hours) decreases the level of CDK12 protein, regardless of the mutational status of the cell line.
BSJ-4-116 inhibits the growth of T-ALL cells (Jurkat and MOLT-4 cells) and sensitizes them to PARP inhibition.
BSJ-4-116 regulates DDR genes via poly(adenylation). BSJ-4-116 overcomes CDK12 mutation. BSJ-4-116 represents the first example of resistance to a bivalent degrader molecule that is a consequence of an acquired point mutation in the target protein.

Cell Proliferation Assay

Cell Line: Parental Kelly and CDK12 cells
Concentration: 10-10000 nM
Incubation Time: 72 hours
Result: Antiproliferative activity of BSJ-4-116 is independent of the mutational status, and the degrader compounds exhibited improved GR50 (growth rate inhibition) values in Kelly CDK12 cells compared with the parental cell line.

Western Blot Analysis

Cell Line: Parental and CDK12 (KellyCDK12CF)-expressing Kelly cells
Concentration: 50 nM
Incubation Time: 6-24 hours
Result: Led to the same level of CDK12 protein level decrease, regardless of the mutational status of the cell line.
