Chromium picolinate 具有降低胰岛素抵抗的作用，对 2 型糖尿病具有潜在的研究价值。

MU1409 是一种MRE11核酸酶抑制剂，其IC50为12.1 μM。除此之外，MU1409 对FEN1和EXO1也有抑制作用，IC50分别为24.2 μM和176.4 μM。MU1409 能影响细胞内DNA修复，阻止BRCA2缺陷细胞中停滞复制叉的降解，这为BRCA2突变相关的癌症研究提供了潜力。

EGFR/BRAFV600E-IN-5 (Compound 7I) 是一种针对BRAFV600E和EGFR的双重抑制剂，其IC50值分别为0.048 μM和0.037 μM。该化合物表现出强大的抗黑色素瘤活性，对MALME-3M和LOX-IMVI细胞系的IC50分别为3.16 μM和2.50 μM。EGFR/BRAFV600E-IN-5通过诱导G1期阻滞、抑制DNA合成以及激活线粒体凋亡(apoptosis)通路来发挥抗肿瘤作用。它可用于黑色素瘤研究，尤其是针对BRAFV600E突变和EGFR信号通路的联合抑制。

Symphytine is a natural inducer of hepatic tumors. Symphytine interacts with DNA in liver endothelial cells and hepatocytes, resulting in DNA damage, mutation induction, and cancer development.

9-Methoxyellipticine是一种天然的生物碱和有效的c-Kit激酶抑制剂，具有细胞毒性，9-Methoxyellipticine能够抑制c-kit(wt)和c-Kit(D816V)，IC50分别为0.8和0.6µM，可用于研究白血病。

MFH290 is a novel cysteine (Cys)-directed covalent inhibitor of CDK12 13. MFH290 forms a covalent bond with Cys-1039 of CDK12, exhibits excellent kinome selectivity, inhibits the phosphorylation of serine-2 in the C-terminal domain (CTD) of RNA-polymerase II (Pol II), and reduces the expression of key DNA damage repair genes. Importantly, these effects were demonstrated to be CDK12-dependent as mutation of Cys-1039 rendered the kinase refractory to MFH290 and restored Pol II CTD phosphorylation and DNA damage repair gene expression. Consistent with its effect on DNA damage repair gene expression, MFH290 augments the antiproliferative effect of the PARP inhibitor olaparib.

Aristolochic acid B (Aristolochic Acid II) 是一种来自马兜铃科分类群的天然产物，是马兜铃酸的主要成分之一。马兜铃酸是诱变剂和致癌物质，Aristolochic acid B (Aristolochic Acid II) 在体内能表现出比 Aristolochic acid I 更大的致癌风险。
