ANTITUMOR AGENT "OLIPIFAT" AND METHOD OF ITS PREPARING Russian patent published in 1999 - IPC

FIELD: medicine, oncology. SUBSTANCE: method involves hydrolysis and extraction of lignin-containing raw in an alkaline medium, oxidation with oxygen-containing gas, separation of the liquid phase, its acidification, separation of obtained precipitate, its washing out up to the neutral pH value, drying, mixing with pyrophosphate, dissolving in water at heating and addition of NaCl to obtain the end product. Method involves also addition of HCl to the end product to obtain the neutral pH value. The precipitate obtained by an alkaline hydrolysis and oxidation of lignin and pyrophosphate as measured for pyrophosphate ions are mixed at the ratio 25:17 by dry matter at precision 10% and dissolved in water. An antitumor agent has a product of an alkaline hydrolysis and oxidation of lignin, pyrophosphate, NaCl and water. It has additionally HCl at amount providing pH 7 at precision 10%. Components have the following ratio by mass at precision 10%: product of hydrolysis and oxidation of lignin 25; pyrophosphate as measured for pyrophosphate ions 17; NaCl 3 and water up to 1000. EFFECT: decreased painfulness of administration of an agent. 2 cl, 1 ex
