Therapy of Walker Carcinosarcoma with Pectin and Cyclophosphane

Published on: 4th October, 2023

Scientific interest in low-molecular-weight pectins is not accidental. Despite the experimental material widely presented in the literature on the pharmacological effects of pectins, the clinical application of the developments has not yet been fully implemented. On the one hand, antitumor potential is registered in polymers with a mass of hundreds of kilodaltons, on the other hand, practically nothing is known about such in pectin derivatives weighing less than 20 kDa. In addition, the issues of assessing the nature of the pharmacological interaction of nanoscale pectin and conventional cytostatics are not covered. The aim of this work is an experimental study of the antitumor potential of low-molecular, low-esterified pectin in combination with a cytostatic agent on a model of Walker’s carcinosarcoma. Pectin therapy of Walker’s transplanted tumor in several series of experiments consistently caused inhibition of its growth from 60% to 80%. The combined use of pectin and cyclophosphane caused inhibition of tumor growth up to 72.4%. The increase in life expectancy in the “pectin + cyclophosphane” group versus the “cyclophosphane” group was 200%. It can be concluded that nanoscale pectin is a promising drug for in-depth study since it meets the criteria of primary screening (increase in animal life expectancy, inhibition of tumor growth, survival without tumor growth).
