    • 13-benzenesulfonylhydrazone anthracyclines useful in producing improved yields in the synthesis 13-deoxyanthrcyclines, and an improved method of reducing 13-benzene-sulfonylhydrazone anthracyclines to 13-deoxyanthrcyclines wherein the reduction reaction is maintained at temperatures of about 55° C. to 64° C. without stirring or agitation. The reaction is completed with the addition of aqueous bicarbonate which forms the 13-deoxyanthracycline and precipitates. The precipitates are filtered and the precipitate and filtrate are extracted separately with organic solvents. The crude 13-deoxy anthracycline can be converted to 5-imino-13-deoxy anthracycline by reaction with methanolic ammonia. The reaction can also be performed with an acidic pyridinium salt instead of a strong acid so that neutralization of the reaction or extraction of the product is not necessary, thereby facilitating purification.
    • 可用于在合成13-脱氧肾上腺素中产生改善产量的13-苯磺酰腙蒽环类抗生素,以及将13-苯磺酰腙蒽环类抗生素还原为13-脱氧肾上腺素的改进方法,其中还原反应保持在约55℃至64℃ ,不搅拌或搅拌。 反应完成,加入形成13-脱氧蒽环并沉淀的碳酸氢盐水溶液。 将沉淀物过滤,并将沉淀物和滤液用有机溶剂分开萃取。 粗制的13-脱氧蒽环霉素可以通过与甲醇氨反应而转化成5-亚氨基-13-脱氧蒽环霉素。 该反应也可以用酸性吡啶鎓盐代替强酸进行,从而不需要中和反应或提取产物,从而有助于纯化。

    • A catheter system comprises a catheter, an inner shaft, an expandable balloon, and an elongate advancement member. The expandable balloon has an unwrapped state and rewrapped state and the advancement member has a first state and a second state. When the advancement member is in the first state the expandable balloon is in the unwrapped state, and when the advancement member is in the second state the expandable balloon is in the rewrapped state. The unwrapped state has a first length and a first diameter, the rewrapped state has a second length and a second diameter, the second length is equal to or greater than the first length, and the second diameter is less than first diameter. The advancement member in the second state extends through the interior region defined by the expandable balloon.
    • 导管系统包括导管,内轴,可膨胀气囊和细长推进构件。 可膨胀气囊具有展开状态和再包裹状态,并且前进构件具有第一状态和第二状态。 当推进构件处于第一状态时,可膨胀气囊处于展开状态,并且当推进构件处于第二状态时,可膨胀气囊处于重新包裹状态。 展开状态具有第一长度和第一直径,再包裹状态具有第二长度和第二直径,第二长度等于或大于第一长度,并且第二直径小于第一直径。 第二状态的前进构件延伸穿过由可膨胀气囊限定的内部区域。
