  • Patent number: 7591996
    Abstract: Selective occlusion of a blood vessel is achieved by selectively damaging endothelial cells at a target location in the blood vessel, resulting in the formation of a fibrin clot proximate to the damaged endothelial cells. Additional fibrinogen can then be introduced into the blood vessel if occlusion is not achieved, as the fibrinogen is converted to fibrin by enzymes released by the exposed thrombogenic tissue and activated platelets. Endothelial cells are selectively damaged using thermal effects induced by ultrasound, by mechanical effects induced by ultrasound, or by mechanical effects produced by a tool introduced into the blood vessel (such as a catheter-based tool). A particularly preferred technique for selectively damaging endothelial cells involves introducing an ultrasound activatable agent into the blood vessel, and causing cavitation in that agent using pulses of high-intensity focused ultrasound having a duration insufficient to induce thermal damage in adjacent perivascular tissue.

  • Publication number: 20090169478
    Abstract: A non-invasive in vivo technique is disclosed, useful for example in detecting cancers and micrometastases. The technique may be used to selectively deliver drugs to target cells such as tumors, metastases, micrometastases, and individual malignant cells. Ligands with specificity for a target cell receptor, and optionally drug molecules as well, are covalently bound to magnetic nanoparticles, either directly or through a spacer molecule. The ligand precludes the need for a separate coating layer. For example, human breast cancer cells express receptors both for luteinizing hormone/chorionic gonadotropin (LH/CG), and for luteinizing hormone releasing hormone (LHRH). These cells can be specifically targeted by iron oxide nanoparticles covalently linked to LH/CG or LHRH. The nanoparticles are incorporated into the cancer cells through receptor-mediated endocytosis. The specific accumulation in targeted cancer cells enhances resolution for imaging, therapy, or both.

  • Patent number: 7422733
    Abstract: Disclosed herein is a class of linkable tetrasaccharide compounds that includes the amino phenyl glycoside of sialyl Lewis X (SLeX) and related analogs. These compounds have conjugatable nucleophilic groups, making them useful in preparing multimeric SLeX compositions. In particular, the disclosed SLeX compounds can be used to prepare selectin binding ligand conjugates by linking them to a reporter moiety, such as a contrast agent, a radiodiagnostic agent, or a cytotoxic or chemotherapeutic agent. The SLeX compounds and conjugates of the invention exhibit binding to selectin that is similar to native Sialyl Lex, and are, therefore, useful for diagnosing and treating selectin-mediated disorders and related conditions.
