    • The invention relates to novel 1,6-anhydro-.beta.-D-hexopyranose derivatives of the formula I ##STR1## in which R.sub.2 is hydrogen, methyl or aromatic acyl, R.sub.3 and R.sub.4 are alkyl, alkenyl or aralkyl and one of the radicals R.sub.3 and R.sub.4 is also an aroyl radical and R.sub.4 can also be hydrogen, with the proviso that the radicals R.sub.3 and R.sub.4 together contain at least 3 carbon atoms and, if R.sub.4 is the benzyl radical, the radical R.sub.3 contains at least 2 carbon atoms, and, if one of the radicals R.sub.3 and R.sub.4 is an aroyl radical, R.sub.2 is hydrogen.These compounds especially the 1,6-anhydro-3,4-di-O-benzyl-.beta.-D-glucopyranose or the 1,6-anhydro-.beta.-D-glucopyranose, can be used as fibrinolytic agents and thrombolytic agents.
    • 本发明涉及式Ⅰ的新颖的1,6-脱水-β-十六吡喃糖衍生物,其中R 2是氢,甲基或芳基酰基,R 3和R 4是烷基,链烯基或芳烷基,其中一个基团R 3 并且R4也是芳酰基,R4也可以是氢,条件是基团R3和R4一起含有至少3个碳原子,如果R 4是苄基,则基团R 3含有至少2个碳原子,和 如果基团R 3和R 4中的一个是芳酰基,则R 2是氢。 这些化合物尤其是1,6-脱水-3,4-二-O-苄基-β-D-吡喃葡萄糖或1,6-脱水-β-D-吡喃葡萄糖可用作纤维蛋白溶解剂和溶栓剂。
