GYKI-13324 is bifunctional nitrosoureido derivative and alkylating agent. GYKI-13324 was studied on human colorectal tumor xenograft lines. Given orally in single or multiple daily doses, GYKI-13324 produced long-term or total regression of adenomatous, but only marginal growth delay of mucinous tumors. GYKI-13324, with slightly lower toxicity than that of BCNU, seems to be a candidate in the clinical management of colorectal tumors.
