partially protected carbohydrates as potential allosteric effectors of hemoglobin. A study toward the construction of seven‐ and eight‐membered cyclic pyrophosphates was also performed on the sugars which had the proper orientation, protection, and number of phosphates. All final compounds were tested for their efficiency on oxygen release from human hemoglobin. Several compounds presented higher potency
多聚磷酸化和过磷酸化的六吡喃糖单糖和二糖是由亲本或部分受保护的碳水化合物合成的,它们是血红蛋白的潜在变构效应物。还对具有正确方向,保护作用和磷酸根数量的糖进行了七元和八元环状焦磷酸酯的构建研究。测试了所有最终化合物对人血红蛋白释放氧气的效率。几种化合物表现出比肌醇更高的效价肌醇六磷酸酯,是已知的血红蛋白变构效应物中最有效的。结构-活动关系进行了分析。亲和力和效率取决于附着在碳水化合物骨架上的磷酸盐的数量,并且主要与存在的负电荷的数量有关。其他效果起作用,但作用较小。
