cdk9-in-11

CDK9-IN-11 是一种有效的CDK9抑制剂，可作为 PROTAC CDK9 Degrader-1 的配体。

CDK9-IN-7 (compound 21e) 是一种高效选择性的，具有口服活性的 CDK9 cyclin T 抑制剂 (IC50=11 nM)，与抑制其他 CDK 相比更有效 (CDK4 cyclinD=148 nM; CDK6 cyclinD=145 nM)。CDK9-IN-7 具有抗癌活性并没有明显的毒性。CDK9-IN-7 诱导非小细胞肺癌 (NSCLC) 细胞凋亡，在 G2 期阻滞细胞周期，并具有抑制非小细胞肺癌干细胞特性。

E3 Ligase Ligand 56 是 E3 连接酶Cereblon的配体，可用于合成 PROTAC CDK9 degrader-11。

PROTAC CDK9 degrader-11 (Compound C3) 是一种口服有效的 PROTAC CDK9 降解剂，DC50 为 1.09 nM。在小细胞肺癌 (SCLC) 细胞中，PROTAC CDK9 degrader-11 展现出强效细胞毒性，其 IC50 达到纳摩尔水平。该化合物可以在 G0 G1 期阻滞细胞周期，并抑制 DMS114 和 DMS53 细胞的侵袭能力。此外，PROTAC CDK9 degrader-11 在 NCI-H446 异种移植小鼠模型中显示出明显的抗肿瘤活性。(Pink: ligand for target protein CDK9 ligand 3; Black: linker; Blue: ligand for E3 ligase Cereblon E3 ligase Ligand 56)

CDK9ligand 3 是一种CDK9的配体，用于合成PROTAC降解剂 [PROTAC CDK9degrader-11]。

CDK9-IN-14 是一种有效的、高低选择性的 CDK9 抑制剂 (IC50: 6.92 nM)。CDK9-IN-14 能够较强的抑制 MV-4-11 细胞和体内肿瘤模型，且毒性较低、副作用少。

CDK9-IN-19 是一种选择性的、高效的 CDK9 抑制剂 (IC50: 2.0 nM)。CDK9-IN-19 表现出良好的癌细胞抗增殖活性、中等药代动力学特性和较低的 hERG 抑制效果。 在MV4-11 异种移植小鼠模型中，CDK9-IN-19 能够明显抑制肿瘤生长。CDK9-IN-19 能够用于急性髓系白血病 (AML) 的研究。

AG-012986 is a multitargeted cyclin-dependent kinase (CDK) inhibitor active against CDK1, CDK2, CDK4 6, CDK5, and CDK9, with selectivity over a diverse panel of non-CDK kinases. AG-012986 showed antiproliferative activities in vitro with IC(50)s of <100 nmol L in 14 of 18 tumor cell lines. In vivo, significant antitumor efficacy induced by AG-012986 was seen (tumor growth inhibition, >83.1%) in 10 of 11 human xenograft tumor models. AG-012986 also showed dose-dependent retinoblastoma Ser(795) hypophosphorylation, cell cycle arrest, decreased Ki-67 tumor staining, and apoptosis in conjunction with antitumor activity.

AG-012986 HCl is a multitargeted cyclin-dependent kinase (CDK) inhibitor active against CDK1, CDK2, CDK4 6, CDK5, and CDK9, with selectivity over a diverse panel of non-CDK kinases. AG-012986 HCl showed antiproliferative activities in vitro with IC(50)s of <100 nmol L in 14 of 18 tumor cell lines. In vivo, significant antitumor efficacy induced by AG-012986 HCl was seen (tumor growth inhibition, >83.1%) in 10 of 11 human xenograft tumor models. AG-012986 HCl also showed dose-dependent retinoblastoma Ser(795) hypophosphorylation, cell cycle arrest, decreased Ki-67 tumor staining, and apoptosis in conjunction with antitumor activity.

JSH-0009 dimaleate (Compound 1) 作为一种CDK9抑制剂，显示出显著效能，其IC50仅为0.928 nM。此外，JSH-0009在小鼠体内对皮下肿瘤（急性髓性白血病 MV4-11）的生长也具有有效的抑制作用。
