Gilvocarcin M

Gilvocarcin M is the minor analogue of a complex of C-glycoside antitumor actives isolated from a Streptomyces sp.. Gilvocarcin M contains a methyl group in the 8-position, and is less active than the vinyl analogue (gilvocarcin V), which is thought to...

Gilvocarcin V

Gilvocarcin V is the major analogue of a complex of C-glycoside antitumor actives isolated from a Streptomyces sp.. Gilvocarcin V contains a vinyl group in the 8-position, and is the most potent analogue of the complex. It is thought to act as an...
