ABSTRACT:
The novel compound of the disclosure is 4-chloro-4-(4-ethoxy-phenyl)-2-(fluoren-9-ylidene-hydrazono)-but-3-enoic acid methyl ester (3F-19), and it alone or in combination with 4-(4-Ethoxy-phenyl)-2-(N′-fluoren-9-ylidene-hydrazino)-2-hydroxy-4-oxo-butyric acid methyl ester (OF-13), appears useful in humans as therapeutic means for the eradication of tumors from the human's colon.
