Abstract
A new xanthone compound named retymicin (1) was isolated together with galtamycin B (2) and saquayamycin Z (3), new members of the galtamycin and saquayamycin families, respectively, and the new lumichrome derivative 1-(α-ribofuranosyl)-lumichrome (4) from Micromonospora strain Tü 6368, isolated from a soil sample collected in Romania. Retymicin, galtamycin B and saquayamycin Z show cytostatic effects to various human tumor cell lines whereas saquayamycin Z is also active against Gram-positive bacteria.
