Abstract: The invention relates to the microbiological and medical industry, genetic engineering, biotechnology. A Saccharomyces cerevisiae yeast strain was obtained on the basis of constructing a recombinant plasmid DNA comprising a structural gene of a human alpha-fetoprotein (AFP) under the control of a regulatory promoter, providing the synthesis and production of AFP in a secreted soluble form, this AFP having activity identical or similar to the activity of a human AFP. The obtained recombinant AFP may be used as an active substance for the preparation of therapeutic agents for use in oncology, immunotherapy, cosmetology and also for the diagnosis of cancer and embryonic pathologies.

Abstract: The present invention provides structures of small molecules capable of modulating apoptotic cell death. More specifically, the structures relate to the structures of apoptotic active sites of mammalian alpha-fetoprotein (AFP) and albumin. Peptides mimicking the active site contain two sequences, Arg-Gly-Asp and Asp-X-X-Asp, wherein X means any amino acid. These sequences are needed in the same molecule for causing a wide range of biological activities. The peptides can be utilized to suppress apoptotic pathways by inhibiting the cytochrome c-mediated caspase activation. Thus, the peptides can be used to inhibit effects of apoptosis induced by oxidative stress, drugs, cytokines, Fas-ligand, alpha-fetoprotein, used to prevent apoptosis in culturing cells, in organ transplantation, in immunological autoimmune disorders and immunodeficiency syndrome induced by viral infection, or to diminish side cytotoxic effects after chemotherapy and radiation therapy.
