Four minor renieramycin-type derivatives, including renieramycins O (1o) and Q-S (1q-s), were isolated from the sponge Xestospongia sp. pretreated with potassium cyanide. Their structures were elucidated by comparison of spectral data with those of recently reported renieramycins M (1m) and N (1n). The results of transformation and cytotoxicity measurements are also described.
