Design and Synthesis of Marine Sarocladione Derivatives with Potential Anticancer Activity.

ABSTRACT: The discovery of structurally novel anti-tumor agents remains a crucial objective in cancer drug research. In this study, we systematically explored the bioactivity potential of sarocladione (5), a structurally unique marine-derived 14-membered ring diketone steroid. Guided by a function-oriented strategy, seven new derivatives (6-13) were synthesized based on an efficient biomimetic synthesis of sarocladione. Evaluation of their antiproliferative activities against human cancer cell lines demonstrated that the intact macrocyclic scaffold is indispensable for activity. Extension of the conjugated π-system led to the identification of compound 8, which exhibited approximately four-fold enhanced potency against HCT116 cells (IC₅₀ = 1.86 µM) compared wit
