Patent number: 7253147Abstract: A modified serum albumin is provided which has been modified in the n-terminal region or binding region VI, such as through a truncation of at least three amino acids at the n-terminal end, so that it exhibits reduced or eliminated binding of trace metals such as nickel and/or copper. Other suitable modifications to this binding region include mutations such as an elongation or insertion which will be sufficient to disrupt the trace metal binding which is highest at this site. The modified albumin of the present invention is advantageous in that its binding to trace metals is reduced or eliminated, and it can thus be used more safely and effectively than unmodified albumin with a reduced or eliminated likelihood of causing an allergic reaction to the trace metal in the human being treated with the albumin composition.Type: GrantFiled: September 7, 2004Date of Patent: August 7, 2007Assignee: New Century Pharmaceuticals, Inc.Inventor: Daniel C.

Patent number: 7179838Abstract: The present invention relates to the albumin-guided development of coumarin analogs and the analogs developed thereby. The coumarin analogs of the present invention are identified and isolated by the fact that they have binding sites to albumin which are different than the binding sites of conventional coumarin analogs such as sodium warfarin, and as a result will be less prone to be displaced since the binding site of sodium warfarin is shared by numerous drugs such as aspirin. The coumarin analogs of the invention are advantageous because they can achieve the effects of the prior coumarin analogs with a minimum of metabolic complications and undesirable side effects.Type: GrantFiled: July 30, 2003Date of Patent: February 20, 2007Assignee: New Century Pharmaceuticals, Inc.Inventor: Daniel C.

Publication number: 20030015132Abstract: An apparatus and method for growing protein crystals or performing other chemical or biological processes, such as the culturing of cells, fungi or bacteria, is provided wherein a stackable tray containing sealable wells for housing a coverslip and a protein solution or other desired biological materials has side walls which extend to provide a base so that the tray may be stacked upon a tray below it, but wherein the sealable wells have a raised bottom which does not extend the same distance and thus are raised above the upper surface of the tray below it. By virtue of the present apparatus, the need to provide a plastic lid on the tray upon which another tray will be stacked is eliminated, and this makes these trays cheaper and more efficient, and allows them to be far more readily handled using robotics or other automated systems to stack, unstack, or manipulate the trays.Type: ApplicationFiled: July 23, 2001Publication date: January 23, 2003Inventor: Daniel C.

Publication number: 20020193318Abstract: The present invention provides methods and formulations for optimizing the anti-cancer and anti-HIV activities of a camptothecin drug, including camptothecin and its related analogs including 9-aminocamptothecin and 9-nitrocamptothecin. The invention involves methodologies and formulations that limit human serum albumin-mediated reduction of the anti-cancer and anti-HIV effects of the camptothecins, and the methods and formulations provide combination therapies in which binding of the camptothecin agent to human serum albumin can be modulated by the administration of a competing agent that also binds human serum albumin. Reduced camptothecin drug binding to human serum albumin can result in elevated camptothecin free drug levels and thus improve the effectiveness of treatment regimens involving these drugs. Further agents such as methotrexate and AZT can also be used in cancer and HIV-positive patients employing camptothecin drugs.Type: ApplicationFiled: March 20, 2002Publication date: December 19, 2002Inventors: Thomas G. Burke, Daniel C. Carter

Patent number: 5948609Abstract: A recombinant serum albumin is provided which has been modified in the heme binding region so as to have the ability when bound to heme to be capable of reversibly binding oxygen. The modifications are directed to replacing at least one of several hydrophobic binding residues in the natural heme binding region with a hydrophilic residue such as histidine, or by inserting a histidine into these regions, and the resulting recombinant hemealbumin complex, or hemalbumin, is able to reversibly transport oxygen in a manner not possible using natural albumin. The resulting oxygen-transporting recombinant hemalbumin compositions of the invention can be utilized as safe and effective blood replacement compositions, or in other applications such as preservation of organs for transplantation which presently use serum albumin, and these compositions will be advantageous because they can function both as blood volume expanders and as oxygen transport systems at the same time.Type: GrantFiled: December 3, 1997Date of Patent: September 7, 1999Inventors: Daniel C. Carter, Joseph X. Ho, Florian Ruker

Patent number: 5780594Abstract: In accordance with the present invention, biologically active protein fragments can be constructed which contain only those specific portions of the serum albumin family of proteins such as regions known as subdomains IIA and IIIA which are primarily responsible for the binding properties of the serum albumins. The artificial serums that can be prepared from these biologically active protein fragments are advantageous in that they can be produced much more easily than serums containing the whole albumin, yet still retain all or most of the original binding potential of the full albumin proteins. In addition, since the protein fragment serums of the present invention can be made from non-natural sources using conventional recombinant DNA techniques, they are far safer than serums containing natural albumin because they do not carry the potentially harmful viruses and other contaminants that will be found in the natural substances.Type: GrantFiled: May 23, 1995Date of Patent: July 14, 1998Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventor: Daniel C.
