  • Publication number: 20100323000
    Abstract: The invention provides novel methods for preparing cardiolipin and cardiolipin analogs having varying fatty acid chain lengths, particularly 1,1?,2,2?-tetramyristoyl cardiolipin. The methods comprise reacting a starting compound, such as a 1,2-O-sn-diacylglycerol and a 2-protected glycerol, with a phosphoramidite reagent to produce a protected cardiolipin, which is deprotected to prepare cardiolipin. The cardiolipin and cardiolipin analogs may be prepared in the presence of an activator, such as pyridinium trifluororacetate. The methods of the present invention are used to prepare cardiolipin and cardiolipin analogs in large quantities. The cardiolipin prepared by the present methods can be incorporated into liposomes which can also include active agents such as hydrophobic or hydrophilic drugs. Such liposomes can be used to treat diseases or in diagnostic and/or analytical assays.

  • Publication number: 20060030578
    Abstract: Delivering therapeutic amounts of irinotecan remains limited due to its highly water insoluble properties. This invention overcomes this limitation by presenting a novel method of preparing liposomal irinotecan by first inactivating irinotecan prior to liposome formation and then subsequently activating the irinotecan by lowering the pH of the lipid composition to an acidic pH of less than about 3.5, such as between 1.5-3.0 or about 2.

  • Publication number: 20050238706
    Abstract: SN38, camptothecin derivatives are poorly water soluble, highly lipophilic camptothecin derivatives and are very active against a variety of human cancers. Because of their very poor water solubility, SN38 has not been used to treat human patients with cancer due to the inability to administer sufficient quantities of dissolved in a pharmaceutical formulation. This invention overcomes these limitations by teaching novel pharmaceutically acceptable SN38 liposome complex formulation for the direct administration of the formulation to human patients with cancer. The claimed invention also describes the methods to prepare liposomal SN38 complexes and antitumor compositions of liposomal SN38 complexes to allow the administration in sufficient amounts to treat various types of cancer and as antiviral agents. This invention is also directed to injectable sterile solutions, antitumor compositions, liposomes.

  • Publication number: 20050148528
    Abstract: The invention provides a method for treating elevated platelet levels in patients using oligonucleotides in formulations that enhance penetration of the oligonucleotide into cells. Certain oligonucleotides found suitable for use in this method are anitisense oligonucleotides. Of the antisense oligonucleotide that are effective, it has been found that antisense oligonucleotides that inhibit the expression of the raf-1 gene can be used, for example, formulated in liposomes. The method has the advantage that the formulation of oligonucleotide can be administered to human patients and the platelet count will decrease in the absence of additional therapeutic treatment steps, including other chemotherapeutic or radiation treatments.

  • Publication number: 20050002918
    Abstract: A method of treating tumors that express a receptor for IL-13 is disclosed. The method involves directly introducing into the tumor a cytotoxin that targets the IL-13 receptor. The cytotoxic agent can be introduced by convection-enhanced delivery through a suitable catheter or by other means. Where a convection-enhanced catheter is employed, the method involves positioning the tip of a catheter at least in close proximity to the tumor. After the catheter is positioned, it is connected to a pump which delivers the active agent through the catheter tip to the tumor. A pressure gradient from the tip of the catheter is maintained during infusion.
