PROTAC CDK9 degrader-2 (compounds 11c) is a potent and selective CDK9 degrader based on PROTAC, with an IC50 of 17 μM in MCF-7 cell lines. Natural product Wogonin binds ubiquitin E3 ligase cereblon (CRBN) via a linker to form PROTAC[1].
KI-ARv-03 是一种高效且选择性的 ATP 竞争性CDK9抑制剂,在 45 μM ATP 浓度下的 IC50 为 0.15 μM,对其他CDK(包括 CDK1-7)的选择性超过130倍。该化合物能够抑制前列腺癌细胞中 AR 驱动的转录和细胞增殖,并可用于研究白血病、胰腺癌、肺泡横纹肌肉瘤 (ARMS) 和去势抵抗性前列腺癌 (CRPC)。此外,KI-ARv-03 是PROTAC靶蛋白的配体 (ligand for target protein for PROTAC),也适用于合成PROTACKI-CDK9d-32[1][2]。
CDK9 Antagonist-1 (compounds 11c) is a potent and selective CDK9 degrader based on PROTAC, with an IC50 of 17 μM in MCF-7 cell lines. Natural product Wogonin binds ubiquitin E3 ligase cereblon (CRBN) via a linker to form PROTAC[1]. CDK9|17 μM (IC50, MCF-7 cells)

CDK7/9-IN-1 is a specific inhibitor of cyclin-dependent kinases 7/9 (CDK7/9). It specifically targets CDK7, while also displaying inhibitory activity against CDK9. CDK7/9-IN-1 demonstrates excellent inhibitory potency against CDK7, with IC50 values of 0.0656 μM and 0.00574 μM without pre-incubation and after 3 hours pre-incubation, respectively. Furthermore, CDK7/9-IN-1 inhibits CDK9 with an IC50 of 2.14 μM after 3 hours pre-incubation. Its application in cancer research makes it valuable for such investigations.
BAY 61-3606 HCl is a cell-permeable, reversible inhibitor of spleen tyrosine kinase. BAY 61-3606 HCl can inhibit degranulation and block cytokine release from mast cells. Oral administration of BAY 61-3606 to rats was shown to suppress antigen-induced passive cutaneous anaphylactic reaction, bronchoconstriction, and bronchial edema. It can also sensitize MCF-7 breast cancer cells to TNF-related apoptosis-inducing ligand (TRAIL)-mediated apoptosis by inhibiting Cdk9. This compound has been used in a pre-clinical model to explore the feasibility of targeting Syk in the treatment of retinoblastoma.
