Patent CA-2227808-A1 (CA)
Inventor: ROBINSON BYRON
IPC: A61K41/00
Filed: 1996-07-23
Abstract: A broad class of photosensitive compounds having enhanced in vivo target tissue selectivity and versatility in photodynamic therapy. Many furocoumarin compounds, such as psoralens, exhibit cytostatic activity when photoactivated but exhibit little in vivo specificity for selectively accumulating in any particular target tissue such as atheromatous plaques. Reactive Oxygen Producing Photosensitizers ("ROPPs") are photoactivatable compounds having an affinity for hyperproliferating cells (such as atheromatous plaque cells), which when photoactivated, produce cytotoxic reaction products. The photoactivity of a ROPP, such as a porphyrin, may be reduced by metalating the porphyrin while the selective affinity of the metalized ROPP for hyperproliferating tissue remains substantially unchanged. By linking a furocoumarin compound to a ROPP to form a F-ROPP, the cytostatic properties of the furocoumarin portion of the F-ROPP can be exploited while the selective affinity of the ROPP portion of the compound for hyperproliferating cells such as atheromatous plaque provides enhanced tissue selectivity without cytotoxicity. In vivo, certain F-ROPPs may be forced to selectively accumulate in a target tissue by illuminating only the target tissue with light having a wavelength operable for photoactivating the F portion of the F-ROPP thereby causing the F-ROPP to either form a monoadduct with or cross-link the cellular DNA in the target tissue. Light of a second wavelength can then be delivered to the target tissue to photoactivate the ROPP portion causing further interference with cellular activity.

Abstract: BHRAM is a system of organizing Dynamic RAM memory for increased burst speeds by means of INFRACYCLE MULTIPLEXING.      Any technology of high speed DRAM may be employed, such as EDO RAM, or SDRAM, but synchronous DRAM is the preferred technology due to speed and timing regularity. Addressing of the DRAM and data READ and WRITE follows the conventional RAS and CAS cycles for that technology, including the banking structure for burst mode operation, but with an important variation, detailed in the SPECIFICATION.      What is added by BHRAM is the ability to read and write data multiple times during a single burst clock cycle, using infracycle multiplexing. Thus, if the SDRAM provides a burst speed of 100 Mhz. on a 100 Mhz. memory bus, then effectively BHRAM can provide a speed of, nominally, 400 Mhz, data access on the same bus. This can be extended to include DRAM on a chip with SRAM to provide very fast cacheing.

Inventor: DEMUTH HANS-ULRICH
IPC: A61K31/00

Abstract: The present invention relates to a novel method in which reduction of the activity of the enzyme Dipeptidyl Peptidase (DP IV or CD 26), or of DP IV - like enzyme activity, in the blood of mammals by specific enzyme effectors will result in a reduced degradation of the endogenous, or exogenously administrated, insulinotropic peptides (incretins), Gastric Inhibitory Polypeptide Glucose-dependent Insulinotropic Polypeptide 1-42 (GIP1-2) and Glucagon-like Peptide 1 7-36 amide (GLP-1 7-36) (or analogs of these peptides). The decrease in concentration of these peptides or their analogs, resulting from degradation by DP IV and DP IV-like enzymes, will be thus be reduced or delayed. As a consequence of the enhanced stability of the endogenous, or exogenously administered, incretins or their analogs, caused by a reduction in DP IV-activity, their insulinotropic effects are enhanced, resulting in a potentate stimulation of insulin secretion from the pancreatic islets of Langerhans, and more rapid removal of glucose from the blood. As a result, glucose tolerance is improved. As a consequence, metabolic abnormalities associated with Diabetes mellitus, including abnormalities of carbohydrate and lipid metabolism, glucosuria and severe metabolic acidosis, and chronic alterations such as microvascular and macrovascular disease and polyneuropathy, which are the consequence of prolonged, elevated circulating glucose concentrations, are prevented or alleviated. The present invention is a new approach to lowering elevated concentrations of blood glucose. It is simple, commercially useful, and is suitable to be used in the therapy, especially of human diseases, which are caused by elevated or extraordinary blood glucose levels.
