Discorhabdin A (1) exhibits a strong cytotoxic activity in vitro, but it is difficult to synthesize and handle due to the instability of its highly strained N,S-acetal structure. We then designed the analogues of discorhabdin A which also have strong cytotoxic activity and stability. The synthesis and examination of the biological activity of various types of stable discorhabdin A oxa analogues (2)
