Kevetrin hydrochloride (4-Isothioureidobutyronitrile hydrochloride) 是一种小分子，是肿瘤抑制蛋白 p53 的激活剂，具有潜在的抗肿瘤活性。

BI-4020 是一种第四代，口服有效，非共价的 EGFR 酪氨酸激酶抑制剂。BI-4020 表现出对三联突变的 EGFR del19 T790M C797S 突变体 ( BaF3 细胞系，IC50=0.2 nM)，双重突变的 EGFR del19 T790M 以及单突变的 EGFR del19 (IC50=1 nM)的抑制剂活性。BI-4020 保留了抑制 EGFR wt 的活性 (IC50=190 nM)。BI-4020 具有高激酶组选择性和良好的 DMPK 性质。

CBR-2092 is a DNA-directed RNA polymerase and DNA topoisomerase inhibitor. CBR-2092 exhibited rifampin-like potency as an inhibitor of RNA polymerase, was an equipotent (balanced) inhibitor of DNA gyrase and DNA topoisomerase IV, and retained activity against a prevalent quinolone-resistant variant. Studies of mutant strains that exhibited reduced susceptibility to CBR-2092 further substantiated RNA polymerase as the primary cellular target of CBR-2092, with DNA gyrase and DNA topoisomerase IV being secondary and tertiary targets, respectively, in strains exhibiting preexisting rifampin resistance.

FI-700 is a novel and potent FLT3 inhibitor with promising antileukemia activity. FI-700 showed a potent IC(50) value against FLT3 kinase at 20 nmol L in an in vitro kinase assay. FI-700 showed selective growth inhibition against mutant FLT3-expressing leukemia cell lines and primary acute myeloid leukemia cells, whereas it did not affect the FLT3 ligand (FL)-driven growth of Wt-FLT3-expressing cells. Oral administration of FI-700 induced the regression of tumors in a s.c. tumor xenograft model and increased the survival of mice in an i.v. transplanted model. Furthermore, FI-700 treatment eradicated FLT3 ITD-expressing leukemia cells, both in the peripheral blood and in the bone marrow. (Source: Clin Cancer Res. 2007 Aug 1;13(15 Pt 1):4575-82.)

AZD3229 Tosylate is a highly potent inhibitor targeting mutant forms of the pan-KIT enzyme, with a primary application in the treatment of gastrointestinal stromal tumors (GISTs).

NX-2127 (ETX2514 Triethylamine) 是一种口服有效的 BTK 抑制剂，可诱导细胞中突变的 BTKC481S 降解。NX-2127 具有有效的抗增殖活性，可抑制 BTKC481S 突变体 TMD8 细胞的增殖。NX-2127 有效催化 Ikaros (IKZF1) 和 Aiolos (IKZF3) 降解，作用浓度分别为 25 nM 和 54 nM。NX-2127 与免疫系统有关，刺激 T 细胞活化并增加原代人 T 细胞中 IL-2 的产生。

IHMT-IDH1-053（compound 16）为高选择性不可逆IDH1R132H突变抑制剂，IC50值仅为4.7 nM。对IDH1wt和IDH2wt 突变体活性低。该化合物在IDH1R132H突变293T细胞中显著抑制2-羟基戊二酸（2-HG）生成，IC50为28 nM。IHMT-IDH1-053通过与IDH1R132H蛋白的Cys269残基形成共价键，结合至NADPH结合袋附近的变构袋。此外，它能够抑制携带IDH1R132突变的HT1080细胞系及原代AML细胞增殖。

UCM-13369 (Compound 4b) 作为一种NPM1抑制剂，它能特异性地针对 NPM1 C+ 的 C 端 DNA 结合域，并下调其相关信号通路。此外，UCM-13369 还能诱导 AML 细胞系与原代细胞的凋亡，对于AML的研究具有重要用途。
