  • Publication number: 20030022866
    Abstract: Several lines of evidence have shown a role for the nitric oxide (NO)/cyclic guanosine monophosphate (cGMP) signaling pathway in the development of spinal hyperalgesia. However, the roles of effectors for cGMP are not fully understood in the processing of pain in the spinal cord. cGMP-dependent protein kinase (PKG) I&agr; but not PKGI&bgr; was localized in the neuronal bodies and processes, and was distributed primarily in the superficial laminae of the spinal cord. Intrathecal administration of an inhibitor of PKGI&agr;, Rp-8-[(4-Chlorophenyl)thio]-cGMPS triethylamine, produces significant antinociception. Moreover, PKGI&agr; protein expression was dramatically increased in the lumbar spinal cord after noxious stimulation. This upregulation of PKGI&agr; expression was completely blocked not only by a neuronal NO synthase inhibitor, and a soluble guanylate cyclase inhibitor, but also by an N-methyl-D-aspartate (NMDA) receptor antagonist, MK-801.

  • Publication number: 20020165202
    Abstract: Novel, heterocyclic compounds having at least one ring nitrogen, disclosed side chains and, in some embodiments, an oxygen ortho to the ring nitrogen inhibit inflammatory responses associated with TNF-&agr; and fibroblast proliferation in vivo and in vitro. The compounds of the invention neither appreciably inhibit the activity of cAMP phosphodiesterase nor the hydrolysis of phosphatidic acid, and are neither cytotoxic nor cytostatic. Preferred compounds of the invention are esters. Methods for the use of the novel compounds to inhibit ceramide-mediated intracellular responses in stimuli in vivo (particularly TN-&agr;) are also described. The methods are expected to be of use in reducing inflammatory responses (for example, after angioplasty), in limiting fibrosis (for example, of the liver in cirrhosis), in inhibiting cell senescence, cell apoptosis and UV induced cutaneous immune suppression. Compounds having enhanced water solubility are also described.

  • Patent number: 6462044
    Abstract: The present invention describes novel nitrosated and/or nitrosylated phosphodiesterase inhibitors, and novel compositions containing at least one nitrosated and/or nitrosylated phosphodiesterase inhibitor, and, optionally, one or more compounds that donate, transfer or release nitric oxide, elevate endogenous levels of endothelium-derived relaxing factor, stimulate endogenous synthesis of nitric oxide or is a substrate for nitric oxide synthase and/or one or more vasoactive agents. The present invention also provides novel compositions containing at least one phosphodiesterase inhibitor, and one or more compounds that donate, transfer or release nitric oxide, elevate endogenous levels of endothelium-derived relaxing factor, stimulate endogenous synthesis of nitric oxide or is a substrate for nitric oxide synthase and/or one or more vasoactive agents.

  • Publication number: 20020127208
    Abstract: The present invention provides a method of transplanting hematopoietic cells between genetically unrelated individuals, comprising administering to the recipient, in combination with the administration of the hematopoietic cells, an amount of mononuclear cells which are treated so as to substantially reduce their ability to cause graft versus host disease while they retain their ability to proliferate in the recipient. The treated mononuclear cells can facilitate engraftment of hematopoietic cells when transplanted in combination with hematopoietic cells, treat or prevent infections, and treat cancer.

  • Publication number: 20020128264
    Abstract: One aspect of the present invention is a method of treating a condition or disease associated with the activity of a multidrug transporter protein comprising administering to a mammal with a condition or disease associated with the activity of a multidrug transporter protein an effective quantity of a purine derivative or analogue, a tetrahydroindolone derivative or analogue, or a pyrimidine derivative or analogue. If the compound is a purine derivative, the purine moiety can be guanine or hypoxanthine. A particularly preferred bifunctional purine derivative is N-4-carboxyphenyl-3-(6-oxohydropurin-9-yl) propanamide. Methods according to the present invention can be used to treat cancer, a microbial or parasitic infection, HIV, infection, or a condition associated with inflammation such as asthma or rheumatic disease.

  • Publication number: 20020102296
    Abstract: The small particle liposome or lipid complex aerosol compounds and methods of treatment of the present invention involve lipid- or water soluble anti-cancer drugs incorporated into liposomes or other lipid complexes. The liposomes and complexes are administered in aqueous dispersions from a jet nebulizer to the respiratory tract of an individual. Various anti-cancer drugs may be used, including 20-S-Camptothecin, 9-Nitro-camptothecin, 9-Amino-camptothecin, 10,11 -methylenedioxy-camptothecin and taxol or its derivatives. Administration of these drugs by inhalation provides faster and more efficient absorption of the anticancer drug than does intramuscular administration or oral administration.
