Capmatinib (INCB28060) 是一种具有口服活性的，选择性的，ATP 竞争性的c-Met 激酶抑制剂，IC50值为0.13 nM。它有效抑制 c-Met 依赖性肿瘤细胞的增殖和迁移，可诱导细胞凋亡，有抗肿瘤活性。

Capmatinib 2HCl (INC-280 2HCl) 是一种新型的 ATP 竞争性 c-MET 激酶抑制剂，IC50 为 0.13 nM。它具有皮摩尔酶效，对 c-MET 具有高度特异性，选择性超过 10, 000 倍一大组人类激酶。该抑制剂在 c-MET 依赖性肿瘤细胞系中有效阻断 c-MET 磷酸化和其关键下游效应子的激活。因此，它在体外有效抑制 c-MET 依赖性肿瘤细胞增殖和迁移，并有效诱导细胞凋亡。

CLEFMA 是一种姜黄素，抑制肿瘤生长与 NF-κB 调节的抗炎和抗转移作用有关，具有抗肿瘤活性。

ATMInhibitor-11 (Compound 1) 是一种针对ATM的高效抑制剂，具有0.32 nM的IC50值，并对KAP1磷酸化显示出0.97 nM的IC50抑制效果。此化合物在ICR小鼠的大脑、心脏和血浆中展示了良好的药物暴露性。在NCI-H441异种移植小鼠模型试验中，ATMInhibitor-11展现了显著的抗肿瘤活性。

TBK1 IKKε-IN-4 is a 6-aminopyrazolopyrimidine derivative and a potent, selective TBK1 and IKKε inhibitor with IC50 values of 13 nM and 59 nM, respectively. TBK1 IKKε-IN-4 shows 100- to 1000-fold less activity against other protein kinases including PDK1, PI3K family members and mTOR[1]. TBK1 IKKε-IN-4 (Compound II; 96 hours; A549 andHCC44 cells) treatmentdisplays selective toxicity in TBK1-dependent cancer cell lines (IC50 of ~ 4.2 μM for H441 cells and IC50 of ~0.4 μM for A549 cells)[1].TBK1 IKKε-IN-4 (Compound II; 0-2 μM; 30 minutes; HCC44 cells) treatment inhibits the AKT activity[1].TBK1 IKKε-IN-4 (Compound II) inhibits LPS-induced expression of IFNβ (IC50 =62 nM), and the IFNβ target genes IP10 (IC50 =78 nM) and Mx1 (IC50=20 nM). TBK1 IKKε-IN-4 effectively blocksTLR3-dependent IRF3 nuclear translocation in cells with an IC50 under 100 nM, but does not impair TNFR1-dependent p65 NFκB nuclear translocation with doses as high as 20 μM[1].

KRC-108 is a multiple kinase inhibitor. KRC-108 is a potent inhibitor of Ron, Flt3 and TrkA as well as c-Met. KRC-108 inhibited oncogenic c-Met M1250T and Y1230D more strongly than wild type c-Met. The anti-proliferative activity of KRC-108 was measured by performing a cytotoxicity assay on a panel of cancer cell lines. The GI(50) values (i.e., 50% inhibition of cell growth) for KRC-108 ranged from 0.01 to 4.22 μM for these cancer cell lines. KRC-108 was also effective for the inhibition of tumor growth in human HT29 colorectal cancer and NCI-H441 lung cancer xenograft models in athymic BALB c nu nu mice. This molecule should serve as a useful lead for inhibitors targeting kinases and may lead to new therapeutics for the treatment of cancer.

HP661是一种针对线粒体复合物I（也称为NADH脱氢酶）的抑制剂，对复合物I具有选择性，以1 µM的浓度抑制其77.6%，而对复合物III抑制率为28.1%，对复合物II和IV则无抑制作用。HP661特异性降低具有高水平氧化磷酸化作用的人类肺癌细胞H460、NCI H441及对trametinib耐药的A549细胞的生存能力（IC50分别为10.6、29.7和15.1 nM），相较于氧化磷酸化水平低的NCI H358人类肺癌细胞（IC50 >10,000 nM）以及非癌性人类胰腺正常上皮细胞（HPNE）和MRC-5人类胎肺成纤维细胞（两者的IC50均>10,000 nM）。当以每天两次，每次30 mg/kg的剂量给药时，HP661在H460小鼠异种移植模型中减少肿瘤体积，并对trametinib引导的肿瘤生长减少产生加成效应。
