Isolation and analysis of high-polymer rna biological activity from baker’s yeast
A new method for an amphiphilic high-polymer RNA producing from dry baker’s yeast is elaborated. The main effect of cheapening and non-waste production is achieved by use of oleic acid (food detergent) as lytic agent at the concentration of 1–2 %. In comparison with known analogues, characterized by the use of 2-ethylhexanoic acid as highly lytic agent, the proposed method does not require a deep cleaning of the final product. The introduction of dry yeast in a cool boiling solution of the lytic agent, without their preliminary soaking can suppress the activity of lysosomal ribonucleases. Non-waste production is that together with the high-polymer RNA, a concentrate feed protein, low molecular weight RNA and natural oligoribonucleotides can be obtained. Experimental verification of the antiviral activity of amphiphilic high-polymer RNA is performed on outbred mice infected with ectromelia virus. It is shown that intramuscular administration of therapeutic doses of preparation to mice causes marked protection from 10 semi-lethal dose (LD50) of ectromelia virus that ranges from 28.6 to 47.6 % depending on the dose. Introduction of preventive doses of preparation leads to greater protection of mice against infection. The protective effect of the preparation has dose-dependent character: the most significant effect is observed at the dose of 1,0 mg/kg of body weight: in this case 61.9 % of animals are survives in experiment, 19.1 % – in control group.
