  • Publication number: 20100310540
    Abstract: Provided are methods of screening compounds for any aspirin-related activity other than TAFI inhibition, and also for non-inhibition of TAFI. Compounds identified by the screening methods can be used to treat, prevent or manage in a patient pain, fever, colon cancer, pancreatic cancer or an inflammatory, platelet aggregation, fibrinolytic or hemorrhagic disease or disorder. Also provided is a method of evaluating test compounds for TAFI inhibitory activity wherein the TAFI inhibitory activity of these test compounds is compared to the TAFI inhibitory activity of aspirin or its derivatives or metabolites. Further provided is a method of treating, preventing or managing in a patient, a hemorrhagic or thrombotic disease or disorder with high dose aspirin or aspirin derivatives or metabolites.

  • Patent number: 7316900
    Abstract: The present invention provides a method of regulating the expression of the urokinase type plasminogen activator (“uPA”) gene in a mammalian cell comprising the steps of: identifying a target nucleotide sequence in a gene of interest, obtaining a methylated antisense oligonucleotide sequence complementary to the target sequence, said oligonucleotide sequence having 5 methylated cytosine in place of unmethylated cytosine in the region complementary to the CpG region in the target nucleotide sequence, and exposing the cell to copies of the oligonucleotide sequence under suitable conditions, such that the oligonucleotide sequence enters the nucleus and interacts with the target sequence to promote methylation of the target nucleotide sequence.

  • Patent number: 6703504
    Abstract: There are provided novel chemical compounds and their uses in the preparation of polymers and oligomers, and the preparation of such compounds. In certain embodiments there are provided dendritic polymers and oligomers, of a type having at least four polymeric or oligomeric organic chains emanating from a single chemical core, each of the chains being of substantially equal length and substantially the same chemical composition. Such compounds may be referred to as dendrimers. Also provided are novel chemical entities useful as core entities in the preparation of dentrimers. Dendrimers can recognize a core substructure to which the polymeric/oligomeric chains (“dendrons”) are covalenty attached and from which they extend with systematic branching radially outward in a three dimensional fashion, to approximately the same extent to each other. Together, core and dendrons constitute macromolecules possessing a high degree of internal structural replication attributable to the branches.

  • Patent number: 6677453
    Abstract: Polymorphic Form (I) finasteride is prepared by first forming a substantially insoluble complex of finasteride and a Group (I) or Group (II) metal salt, such as lithium bromide, and then dissociating the complex by dissolving away the salt component with water, so as to obtain substantially pure Form (I) polymorphic crystalline finasteride.

  • Patent number: 5932709
    Abstract: The present invention relates to chemotherapeutic agents, and more particularly, to novel analogs of camptothecin. The camptothecin analogs display increased solubility through the hydrophilicity of added non-ionic sugar substituents. In accordance with the present invention, a member from the class of novel camptothecin analogs is to be delivered in vivo as a chemotherapeutic agent to fight cancer growth in the body.

  • Patent number: 5783702
    Abstract: Cisapride, i.e. cis-4-amino-5-chloro-N-?1-?3-(4 fluoro-phenoxy)propyl!-3-methoxy-4-piperidinyl!-2-methoxy-benzamide, and similar benzamide derivatives, are prepared from novel 1-aryloxyalkyl- or 1-aralkyl-3-arylcarbonyloxy-4-oxo-piperidines, by nuclear substituent re arrangement involving acyl transfer under animal forming conditions, to give the corresponding 1-aryloxyalkyl- or 1-aralkyl-3-hydroxy-4-lower alkoxy-4-arylamido piperidine. This in turn is readily converted to the corresponding 3-oxo-4-arylamido-piperidine by reaction with strong organic acid, which can then be reduced, deprotected and 3-methylated to give the final compound, e.g. cisapride.

  • Patent number: 5371240
    Abstract: 3-substituted thiophene compounds contaminating the analogous 2-substituted thiophene compounds, e.g. 3-acetylthiophene contaminating 2-acetyl thiophene, are removed by a selective electrophilic substitution process, e.g. bromination, followed by fractional distillation. It has been found that electrophilic substitution as exemplified by bromination is highly selective towards the 3-substituted thiophenes, yielding compounds of significantly higher molecular weights for separation purposes, to give high purity 2-substituted thiophene compounds.
