A search for the methods new in principle which should block and eliminate AIDS-associated mycoplasmas was carried out. This work was conducted in two ways: 1) inhibition of vital activity of Mycoplasma fermentans PG-18 and Acholeplasma laidlawii PG-8 by 6-azacytidine; 2) establishment of carbohydrate composition of receptors for these mycoplasmas aimed at the competitive elimination of these microorganisms from urogenital tract of a man using carbohydrates. It is established that a 50%-inhibiting concentration of 6-azacytidine was 23.4 micrograms/ml for M. fermentans PG-18 and 62.5 micrograms/ml for A. laidlawii PG-8. alpha-D-glucose and N-acetylneuramine acid are two terminal carbohydrates that can serve as receptors for M. fermentans on human mucous membranes while D-mannose and N-acetyl-D-glucosamine for A. laidlawii PG-8. alpha-D-glucose in concentration 75 mM and N-acetylneuramine acid in concentration 150 mM competitively inhibit reception of M. fermentans on mucosae, while D-mannose in concentration 150 mM and N-acetyl-D-glucosamine in concentration 75 mM are antireceptor substances for A. laidlawii.
开展了对可阻断和消除艾滋病相关支原体的新原理方法的探索。这项工作通过两种方式进行:1)用6-氮杂胞苷抑制发酵支原体PG-18和莱氏无胆甾原体PG-8的生命活动;2)确定这些支原体受体的碳水化合物组成,旨在利用碳水化合物从男性泌尿生殖道竞争性消除这些微生物。已确定,6-氮杂胞苷对发酵支原体PG-18的50%抑制浓度为23.4微克/毫升,对莱氏无胆甾原体PG-8为62.5微克/毫升。α-D-葡萄糖和N-乙酰神经氨酸是两种末端碳水化合物,可作为人黏膜上发酵支原体的受体,而D-甘露糖和N-乙酰-D-葡萄糖胺是莱氏无胆甾原体PG-8的受体。浓度为75 mM的α-D-葡萄糖和浓度为150 mM的N-乙酰神经氨酸竞争性抑制黏膜上发酵支原体的受体作用,而浓度为150 mM的D-甘露糖和浓度为75 mM的N-乙酰-D-葡萄糖胺是莱氏无胆甾原体的抗受体物质。
