A presumed natural source of hydantoins is parabiochemical reaction in living organisms. It is known that 3-(2,5-dioxo-2,5-dihydroimidazol-4-yl)propionic acid (I) is formed from α-ketoglutaric acid and urea in the reaction accompanying the Krebs cycle. Biological necessity of its existence in the living objects can be attributed to the need to urea fixation to reduce the inhibitory effect of its high
一种推测的乙内酰脲的天然来源是生物体内的超生化反应。已知3-(2,5-二氧代-2,5-二氢咪唑-4-基)丙酸(I)是由α-酮戊二酸和尿素在伴随克雷布斯循环的反应中形成的。它存在于活体中的生物学必要性可归因于需要固定尿素以降低其高浓度对细胞酶的抑制作用[2, 3]。1:1的试剂。该溶液具有水纹颜色,一段时间后形成黄米色沉淀。分离沉淀后,蒸馏滤液得到乙内酰脲衍生物 IIa-IId。在中性介质中,反应速率大大降低。DOI: 10.1134/S1070363213070323
