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

Artemisinin is a potential anticanceragent with an interesting trioxane sesquiterpene structure. In order to improve the biological activity and metabolic stability of artemisinin, a series of novel ring-contracted artemisinin dimers were synthesized. These dimers were evaluated by MTT assay against six cancer cell lines. Most of the dimmers exhibited improved antiproliferative activities over artemisinin

Bromoacetal 2 undergoes a novel ring-contracted reaction to give the aldehyde 3 in the presence of DBU or triethylamine. The aldehyde 3 is reduced to the alcohol 4 and oxidized to the carboxylic acid 5. The alcohol 4 reacts with dihydroartemisinin to give the two diastereoisomers 38 and 39. All the compounds were tested for antimalarial activity in mice infected with chloroquine sensitive Plasmodium
