The research focused on investigating the immuno-stimulating properties of certain glycosylthiourea and 3-glycosyl-4-hydroxyhexahydropyrimidine-2-thiones as stimulators of non-specific resistance to infection. The purpose was to understand the action of these compounds on natural immunity, particularly on the resistance of an organism to infection. The study utilized a series of compounds, including 3[B-D-gluco(galacto)-pyranosyl]-4-hydroxyhexahydropyrimidine-2-thiones (I and II), N'-[B-D-gluco(galacto)pyranosyl]-N3-(2-methyl-4-oxopentyl-2)thiourea (III and IV), and N'-[B-D-gluco(galacto)-pyranosyl]-NS-(3,3-diethoxypropyl)thiourea (V and VI), along with their aglycones. The synthesis involved chemicals such as 2,3,5-tri-O-acetyl-8-D-ribofuranosylisothiocyanate (VIII), 4-amino-4-methyl-2-pentanone (IX), and 3,3-diethoxypropylamine (X). The conclusions drawn from the biological experiments indicated that all test compounds demonstrated some level of stimulating action, with an index of resistance ranging from 2 to 6, and were comparable to known immunostimulators like taftsin, rigin, and levamisole. The effectiveness of these compounds was associated with an increase in proliferating processes in lymphoid and hematopoietic tissues, as evidenced by an increase in the number of stem cells in the spleens of lethally irradiated mice that received the test compounds.
