  • Patent number: 10383823
    Abstract: The present invention provides a composition for the treatment of cancer including zwitterionic liposomes consisting essentially of: 50-65 mol % of a phosphatidylcholine lipid, 30-45 mol % of cholesterol, and 2-8 mol % of a PEG-lipid; and cisplatin. Cisplatin is encapsulated in the liposomes in an amount such that the ratio of the total lipid weight to the cisplatin weight is from about 65:1 to about 95:1. Methods for the preparation of liposomal cisplatin and the treatment of cancer are also disclosed.

  • Publication number: 20160250177
    Abstract: The present invention provides compositions for the treatment of cancer. The compositions include liposomes containing a phosphatidylcholine lipid, a sterol, a PEG-lipid, and a taxane. The PEG-lipid constitutes from about 2 to about 8 mol % of the lipids in the liposome. The taxane is docetaxel esterified at the 2?-O position with a heterocyclyl-(C2-5 alkanoic acid). The present invention also provides liposomal compositions for the treatment of cancer comprising administering to a patient in need thereof a liposome, wherein the liposome comprises: a phosphatidylcholine lipid; a sterol; a PEG-lipid; and a taxane or a pharmaceutically acceptable salt thereof; wherein the taxane is docetaxel esterified at the 2?-O-position with a heterocyclyl-(C2-5alkanoic acid); and wherein upon administration of the liposomal composition to the patient, the plasma concentration of docetaxel remain above an efficacy threshold of 0.2 ?M for at least 5 hours.

  • Publication number: 20110062093
    Abstract: A file storage device, including a base member, and a plurality of dividing members detachably attached to the base member in a substantially parallel configuration, adjacent dividing members defining storage areas therebetween. The storage areas have widths, so that removal or addition of at least one dividing member allows for variation of the storage area widths.

  • Publication number: 20070106086
    Abstract: 3,3-Dimethylbutanal is prepared from 3,3-dimethylbutanol. Intermediate 3,3-dimethylbutanol is obtained by reacting ethylene, isopropylene and a mineral acid to produce a 3,3-dimethylbutyl ester which is hydrolyzed to the alcohol. The hydrolysis step is effectively carried out by reactive distillation. Alternatively, 3,3-dimethylbutanal is prepared from 3,3-dimethylbutanol obtained by reduction of the corresponding carboxylic acid or 1,2-epoxy-3,3-dimethylbutane, or by hydrolysis of 1-halo-3,3-dimethylbutane. Fixed bed gas phase and stirred tank liquid phase processes are provided for converted 3,3-dimethylbutanol to 3,3-dimethylbutanal by catalytic dehydrogenation.
