non-small cell lung cancer. In vitro assays showed that NY-2 significantly inhibited tumor colony formation, invasion, and migration and increased LDH activity and apoptosis in a concentration-dependent manner in non-small cell lung cancer cells. NY-2 also inhibited the formation of lung metastases without significant toxicity to major organs in nude mice.Conclusion: Compared with the parent compound, ZLDI-8
简介:ZLDI-8是ADAM-17的抑制剂,作用于Notch信号通路,具有较强的抗肿瘤活性。为了进一步优化其结构,提高其活性,合成了一系列ZLDI-8的衍生物。NY-2是体外初步活性筛选最有效的衍生物,给药后无明显毒性体内.方法:本研究旨在确定化合物 NY-2 对非小细胞肺癌 (NSCLC) 的药代动力学、组织分布、肝毒性、肾毒性和抗肿瘤活性体外和体内.结果:NY-2的体内药代动力学参数优于ZLDI-8。组织分布分析表明,大鼠尾静脉注射6 mg/kg NY-2导致肺部浓度最高,因此我们推测NY-2可能对治疗非小细胞肺癌有效。体外试验表明,NY-2 在非小细胞肺癌细胞中以浓度依赖性方式显着抑制肿瘤集落形成、侵袭和迁移,并增加 LDH 活性和细胞凋亡。NY-2对裸鼠肺转移灶的形成也有抑制作用,对主要脏器无明显毒性。结论:与母体化合物ZLDI-8相比,NY-2的活性和安全性更高。NY-2 作用于
