Abstract
A Sarcoma 180 tumor growth inhibiting glycoprotein material produced extracellularly from Candida albicans is provided. The inhibitor material is effective to arrest Sarcoma 180 tumor angiogenesis thereby causing tumor regression. The preferred inhibitor material is an extracellular glycoprotein produced from Candida albicans SA#1 (CBS 5736) cultured in a glucose containing chemical medium with a filtrate of the growth medium precipitated with ethanol. Dosage innoculations of the precipitate into the peritoneal cavities of Sarcoma 180 tumor infected mice effect substantial tumor regression.
Claims5
The method of making a Sarcoma 180 tumor growth inhibitor which comprises culturing Candida albicans SA#1 (CBS 5736) microorganism in a chemical medium containing glucose for about 30 days at about 30.degree. C., centrifuging the resulting growth medium, discarding the cells, precipitating the remaining filtrate with ethanol, and recovering the resulting glycoprotein of the precipitate.
