Simple methods for screening of potential anticancer agents and other remedies

Статья. — 7 стр. Institute of Experimental Pathology, Oncology and Radiobiology of NAS of Ukraine, Kiev, Ukraine.В статье представлено краткое описание собственных патентов и других публикаций по вопросам первичного скрининга веществ, разрабатываемых как потенциальные лекарственные препараты или продукты лечебного питания, в особенности в онкологии.The aim of this study was to elaborate quick, simple and low-cost methods for preliminary screening of a broad spectra of drugs and medical foods suggested to be used in clinical oncology. Materials and methods. The methods have been elaborated are based on originally modified cancerolysis reaction (I group) and on viscosimetry and spectrofotometry of the lysates of tumor tissue and tissue of potential side toxicity target organs prepared with certain detergent (II group). The methods were tested using the following experimental tumor models: Ehrlich carcinoma (ascitic and solid form), Lewis lung carcinoma, Ca755 mammary carcinoma, B16 melanoma, P388 and L1210 lymphatic leukemia; in rats – Guerin carcinoma (a standard strain and original cisplatin-resistant and doxorubicin-resistant substrains), Walker W-256 mammary carcinosarcoma. Results. In the cancerolysis methods, in each case, the sign (+ or -) of cancerolysis modulations and tumor growth retardation indexes were identical if the same food or drug was applied. At the same time, absolute value of did not correlate significantly. The viscosimetry methods adequtely reflected a priori known therapeutic and toxic effects of the anticancer drugs. Conclusion. So, both groups of the methods show adequacy to the task of preliminary screening.
Key words: anticancer drugs, non-clinical investigations, screening, drug sensitivity, side toxicity, in vivo methods.
