Aristoforin
Aristoforin, a hypericin derivative, inhibits the activities of SIRT1 and SIRT2. Aristoforin induces G1 phase cell cycle arrest, scavenges hydroxyl free radicals, and exhibits protective activity against Fe2+-induced DNA breakage. Aristoforin can be used in studies related to breast cancer and colon adenocarcinoma.
