The endoperoxide group of artemisinins is universally accepted an essential group for their anti-cancer effects. In this study, a series of D-ring-contracted artemisinin derivatives were constructed by combining ring-contracted artemisinin core with fragments of functional heterocyclic molecules or classical CDK4/6 inhibitors to identify more efficacious breast cancer treatment agents. Twenty-six novel

生物,以鉴定更有效的乳腺癌治疗药物。合成了 26 种新型杂化分子,并通过 HRMS、IR、 1 H-NMR 和13 C NMR 进行了表征。在抗增殖活性和激酶抑制作用测定中,我们发现B01的抗增殖作用与阳性对照Palbociclib接近,对T47D细胞和
MDA-MB-436的GI 50值为4.87±0.23 μM和9.97±1.44 μM细胞分别。此外,结果显示B01是对抗CDK6/cyclin D3激酶最有效的化合物,IC 50值为0.135±0.041 μM,其活性约为阳性对照Palbociclib的1/3。
