    Annelations of xanthines by the reaction of dimethyl acetylenedicarboxylate (DMAD) with 7-alkyl-8-amino-1, 3-dimethylxanthines (3) have been investigated. Treatment of 3 with DMAD in refluxing methanol gave 5-alkyl-1, 3-dimethyl-9-methoxycarbonyl-1, 2, 3, 4-tetrahydro-5H, 7H-pyrimido[1, 2-e]purine-2, 4, 7-triones (4) and 7-alkyl-1, 2, 3, 6-tetrahydro-1, 3-dimethyl-8-(1, 2, 4, 5, 6, 7-hexamethoxycarbonyl-3-azatricyclo[2.2.1.02, 6]heptyl)purine-2, 6-diones (10). However, when the reaction was run in N, N-dimethylformamide, 5-alkyl-1, 3-dimethyl-1, 2, 3, 4-tetrahydro-7, 8, 11-tris(methoxycarbonyl)-5H, 9H[1, 3]-diazocino[1, 2-e]purine-2, 4, 9-triones (11), 5-alkyl-1, 3-dimethyl-7, 8-bis(methoxy-carbonyl)-1, 2, 3, 4, 9, 10-hexahydro-10-(methoxycarbonyl)methylene-5H[1, 3]-diazepino[1, 2-e]purine-2, 4, 9-triones (12), and 5-alkyl-1, 3-dimethyl-1, 2, 3, 4, 9, 10-hexahydro-7, 8, 9, 10-tetrakis(methoxycarbonyl)-5H[1, 3]-diazepino[1, 2-e]purine-2, 4-diones (13) were formed.

    The present disclosure is related to compositions useful in the field of foods and beverages. In particular, the present invention relates to those compositions that reduce the postprandial rise in blood glucose (described as low Glycemic Index) that synergistically provide enhanced metabolism in the mammalian system and inhibit the storage of systemic fat. In particular, the present invention relates to compositions comprising: a) one or more flavanols; b) one or more bracers; and c) vitamin B; wherein the composition exhibits a Glycemic Index of about 55 or less. As disclosed, the unique combination of ingredients, which provide the defined, low Glycemic Index, work synergistically together to enhance perception of energy and/or improve physiological energy via metabolism enhancement over a long duration of time, without resulting in sudden peaks of glucose in the mammalian system. Thus, the present compositions effectively modulate glucose in the system, thereby providing energy to the system without resulting in the storage of systemic fat.
    本公开涉及在食品和饮料领域有用的组合物。特别是,本发明涉及那些能够减少餐后血糖上升(描述为低升糖指数)的组合物,这些组合物在哺乳动物系统中协同作用,提供增强的代谢作用并抑制系统性脂肪的储存。特别是,本发明涉及包括:a)一种或多种黄烷醇;b)一种或多种支链氨基酸;和c)维生素B的组合物;其中该组合物表现出约55或更低的升糖指数。如本文所述,这些独特的成分组合,以定义的低升糖指数为特征,协同作用,能够提高能量感知和/或通过代谢增强长时间改善生理能量,而不会导致哺乳动物系统中的血糖突然峰值。因此,本组合物有效地调节系统中的葡萄糖,从而为系统提供能量而不导致系统性脂肪的储存。
