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.

CDK7-IN-20 是一种有效的、选择性的、不可逆的 CDK7(CDK) 抑制剂，IC50值为 4 nM。CDK7-IN-20 对 CDK7的选择性超过 CDK1、CDK2、CDK3、CDK5、CDK6、CDK9 和 CDK12的 206 倍以上。CDK7-IN-20 具有用于常染色体显性多囊肾病 (ADPKD) 研究的潜力。

CDK9-IN-27（Compound 6a）是一款针对CDK9的抑制剂，其IC50s为0.424 μM。该化合物可诱导细胞凋亡（apoptosis）及S期细胞周期停滞，并对HepG2、HCT-116及MCF-7细胞系展现出细胞毒性，其IC50s介于10.31至40.34 μM之间。CDK9-IN-27主要应用于癌症相关研究领域。

LL-K9-3是一种基于选择性疏水标记技术（HyT）的CDK9-cyclin T1复合物降解剂（DC50值分别为cyclin T1的589 nM和CDK9的662 nM）。它由CDK9抑制剂SNS 032和一个糖基连接器连接到疏水标记组成。LL-K9-3不会降解其他CDKs（CDK1、2、4、5、6和7）。在22RV1细胞中，LL-K9-3通过诱导CDK9和cyclin T1的选择性和同步降解，降低雄激素受体（AR）和cMyc的表达。
