Vibsanin A is an 11-membered vibsane diterpenoid and is reported to induce myeloid cell differentiation via activation of protein kinase C (PKC) without tumor-promoting activity. Therefore, vibsanin A is thought to be an attractive compound for acute myeloid leukemia (AML) therapy. In this study, we synthesized vibsanin A analogs and compared the activity of these compounds for PKC activation and myeloid cell differentiation. We found that the hydroxymethyl group in vibsanin A is an important substituent to induce differentiation of AML cells. Collectively, our results showed the biochemical features of vibsanin A and provided new insights into the development of new antileukemic drugs.
