Patent PT-832096-E (PT)
Inventor: KENT STEPHEN B H
IPC: C08L89/00
Filed: 1995-05-04
Abstract: Proteins of moderate size having native peptide backbones are produced by a method of native chemical ligation. Native chemical ligation employs a chemoselective reaction of two unprotected peptide segments to produce a transient thioester-linked intermediate. The transient thioester-linked intermediate then spontaneously undergoes a rearrangement to provide the full length ligation product having a native peptide bond at the ligation site. Full length ligation products are chemically identical to proteins produced by cell free synthesis. Full length ligation products may be refolded and/or oxidized, as allowed, to form native disulfide-containing protein molecules. The technique of native chemical ligation is employable for chemically synthesizing full length proteins.

IPC: A61K9/00
Filed: 1996-06-04
Abstract: A- and/or B-ring substituted camptothecin derivatives, which are poorly water soluble (less than 5 micrograms per milliliter of water), are highly lipophilic camptothecin derivatives (HLCD) and are very active against a variety of human cancers. Because of their very poor water solubility, HLCD have not been used to treat human patients with cancer due to the inability to administer sufficient quantities of the HLCD dissolved in a pharmaceutical formulation. This invention overcomes these limitations by teaching novel pharmaceutically acceptable HLCD formulations for the direct administration of HLCD to human patients with cancer. The claimed invention also describes the methods to create solutions of HLCD and antitumor compositions of HLCD to allow the administration of HLCD in sufficient amounts to treat human patients with various types of cancer. This invention is also directed to injectable sterile solutions, antitumor compositions, solutions and suspensions comprising N-methyl-2-pyrrolidinone and a highly lipophilic camptothecin derivative.

Abstract: A fuel conditioning assembly, structured to be positioned between a fuel supply and a fuel combustion assembly, and including an elongate tubular housing having an inlet end, an outlet end, and a flow through passage extending therebetween. The inlet end is coupled with the fuel supply so as to receive fuel flow therethrough into the flow through passage, wherein a turbulent flow of the fuel is initiated and the fuel is influenced by a combination of metallic elements which chemically condition the fuel flowing through the flow through passage by rearranging the molecular bonds of the fuel with a catalytic effect and separating the fuel particles into a plurality of subatomic particles, thereby reducing a density of the fuel and substantially increasing a fuel burn efficiency. Further, the outlet end of the housing is coupled directly with the fuel combustion assembly so as to provide for the flow of conditioned fuel therebetween without a substantial risk of a diminishing of the effects of the conditioning.
