The antitumor activity of berberine, berberrubine, and their derivatives against sarcoma-180 ascites was determined by the total packed cell volume method. Berberine and tetrahydroberberine derivatives had no antitumor activity, but berberrubine (9-demethylberberine) and the ester derivatives of berberrubine had a strong antitumor activity. ED90 of berberrubine, its acetate and benzoate, were 15, 23, and 44mg/kg, respectively. The therapeutic indices (LD10/ED90 by the present method) of these compounds were as follows: Berberrubine hydrochloride, 6.7∼9.4; 9-acetyl-9-demethylberberine (9-acetylberberrubine) chloride, 7.6∼8.7; 9-benzoyl-9-demethylberberine (9-benzoylberberrubine) chloride, 3.4∼4.9.

Antitumor polysaccharide preparations G-Z and P-Z were fractionated from the water soluble extracts of Ganoderma applanatum (PERS.) PAT and Phellinus linteus (BERK. et CURT) AOSHIMA, basidiomycetes of Polyporaceae, respectively, by fractional precipitation with ethanol and cetyltrimethylammonium hydroxide. The structures of G-Z and P-Z consist of β-(1→3), (1→4) linked D-glucose residue, and β-(1→3) linked D-glucose residue, respectively. These polysaccharide preparations have marked antitumor activity against transplanted sarcoma 180 in mice, and a complete regression of tumors was observed in more than half of animals with no sign of toxicity. Some derivatives of P-Z were synthesized and their antitumor effects were also examined.
