DC_AC50 是一种 Atox 和 CCS 的双抑制剂，是一种抑制细胞内铜伴侣作为减少 预防获得性化疗耐药性的手段。它与 Atox1 和 CCS 结合并减少癌细胞增殖和肿瘤生长。

Inobrodib (CBP-IN-1) 是一种口服活性的强选择性p300 CBP 抑制剂，与 p300 和 CBP 结合，Kd 值为 1.3 和 1.7 nM。它抑制前列腺癌细胞系的细胞增殖并降低雄激素受体和 C-MYC 调节的基因表达。

Oxaliplatin (L-OHP) 是一种 DNA 烷化剂，一种 DNA 合成抑制剂。Oxaliplatin 会导致 DNA 交联损伤，阻止 DNA 复制和转录并导致细胞死亡。Oxaliplatin 可以诱导细胞自噬。

Calmidazolium chloride (R 24571) 是一种钙调蛋白拮抗剂，对CaM 依赖性磷酸二酯酶和钙调蛋白诱导的红细胞Ca2+转运ATP 酶活化有拮抗作用，IC50分别为0.15和0.35 μM。Calmidazolium chloride 结合CaMK 的Kd 值为3 nM。Calmidazolium chloride 在抗癌领域有研究的价值。

Sulfo-SMCC sodium 是一种异双功能、不可裂解的 ADC 交联剂，带有 N-羟基琥珀酰亚胺酯和马来酰亚胺基团，分别与伯胺和巯基反应。

The metallo-protein Cu/Zn-superoxide dismutase (SOD1) is a ubiquitous enzyme responsible for scavenging superoxide radicals. Mutations in SOD1, which alter its metal binding capacity and can result in protein misfolding and aggregation, have been linked to familial amyotrophic lateral sclerosis (ALS). Cu-ATSM is an orally bioavailable, blood-brain barrier permeable complex that has traditionally been used in cellular imaging experiments to selectively label hypoxic tissue via its susceptibility to reduction by oxygen-depleted mitochondria. More recently, Cu-ATSM has been reported to improve locomotor function and survival in a transgenic ALS mouse model by delivering copper specifically to cells in the spinal cords of mice producing misfolded SOD1 proteins. Copper chaperone for SOD (CCS) is presumed to utilize the copper from Cu-ATSM to prevent misfolding of the SOD1 protein.

DA-PROTAC是Atox1和CCS铜离子转运蛋白的有效PROTAC降解剂。该化合物能够与Atox1和CCS结合形成复合体，进而与E3连接酶相结合，引起Atox1和CCS的泛素化水平增加，最终通过蛋白酶体途径导致这两种蛋白的降解。DA-PROTAC在三阴性乳腺癌的研究中有应用潜力。
