Abstract: This invention relates to certain novel 2'-halomethylidene, 2'-ethenylidene and 2'-ethynyl cytidine, uridine and guanosine derivatives, and compositions thereof, which are useful in the treatment of patients afflicted with neoplastic or viral disease states.

Abstract: Ligand inhibitors for increasing levels of free corticotropin-releasing factor (CRF) in the brain. Such ligand inhibitors cause release of CRF from the CRF/CRF-binding protein complex. Administration of the ligand inhibitors provide improvement in learning and memory, result in decreased food intake and/or provide treatment for diseases associated with low levels of CRF in the brain, notably Alzheimer's disease.

Abstract: Antagonists of neurokinin A which are derivatives of naturally occurring neurokinin A in which the amide bond connecting the two amino acids on the carboxy terminal end is modified are described. The antagonism is confirmed using conventional competitive binding and biochemical assays as well as conventional physiological tests and the use of these derivatives in a variety of conditions in which neurokinin A is implicated is also described.

Abstract: CRF receptor antagonists are disclosed. Such receptor antagonists are thiadiazole-, pyrimidine-, triazine-, and triazole-containing compounds substituted with both a C3-C14 monocyclic or fused, homoaryl or heteroaryl group and a substituted amine group. The CFR receptor antagonists have utility in the treatment of a variety of disorders, including disorders associated with the hypersecretion of CRF.

Abstract: The present invention is directed toward a novel process of preparing 2'-exocyclic vinylfluoride derivatives of cytidine analogues for use as ribonucleotide reductase inhibitors.

Abstract: This invention relates to certain novel 2'-halomethylidene, 2'-ethenylidene and 2'-ethynyl cytidine, uridine and guanosine derivatives, and compositions thereof, which are useful in the treatment of patients afflicted with neoplastic or viral disease states.

Abstract: The present invention is directed toward a novel process of preparing 2'-exocyclic vinylfluoride derivatives of cytidine analogues for use as ribonucleotide reductase inhibitors. The novel process of the present invention utilizes a cytidine derivative as the required starting material and provides the ribonucleotide reductase inhibitor in a more efficient than the reaction sequence. The process is more efficient than the process disclosed by McCarthy et al. in European Patent Application Publication No. 0 372 268 published Jun. 13, 1990, in that it requires fewer chromatographies and results in an overall yield of greater than 25% for the five steps. The present invention further provides the ribonucleotide reductase inhibitor in a four step reaction sequence and results in an overall yield of greater than 35%.

Abstract: This invention relates to certain aristeromycin/adenosine derivatives which are useful in inhibiting AdoMet-dependent transmethylation and in the treatment of patients afflicted with neoplastic or viral disease states.

Abstract: The present invention provides novel 5-(1-fluorovinyl)-1H-pyrimidine-2,4-dione derivatives which are useful as antineoplastic agents by themselves or in conjunctive therapy with the antineoplastic agent 5-fluorouracil.

Abstract: There is disclosed a process for preparation of L-carnitine from (S)-3-hydroxybutyrolactone. The process is a two-step preparation in which (S)-3-hydroxybutyrolactone is first converted to a hydroxy-activated form and subsequently transformed to L-carnitine by treatment of the hydroxy-activated (S)-3-hydroxybutyrolactone with trimethylamine in water.

Abstract: The present invention relates to a method of effecting immunosuppression in a patient in need thereof comprising administering to said patient an effective immunosuppressive amount of certain 5'-vinylhalo-aristeromycin/adenosine analogs.

Abstract: This invention relates to certain novel 2'-halomethylidene, 2'-ethenylidene and 2'-ethynyl cytidine, uridine and guanosine derivatives, and compositions thereof, which are useful in the treatment of patients afflicted with neoplastic or viral disease states.

Abstract: The present invention relates to certain novel piperidyl ethers and thioethers which are useful as inhibitors of cholesterol biosynthesis and as agents which lower total serum cholesterol in patients in need thereof.

Abstract: The present invention relates to a group of compounds which are novel substituted alkyl piperidines and which act to inhibit the synthesis of cholesterol in mammals and in fungi.

Abstract: Imidazole-2-thione derivatives useful as antihypertensive agents are described herein. The compounds are obtained by cyclization of an appropriate open-chain compound such as an appropriately substituted thiourea.

Abstract: This invention relates to a process for making di-fluoro analogs of squalene.

Abstract: This invention relates to novel derivatives of 2,2'-bi-1H-imidazoles, to the processes and intermediates used in their preparation, to their ability to exert the pharmacologic effects of lowering high blood pressure and of increasing heart contractile force and to their use as chemotherpauetic agents useful in treating cardiac insufficiency and hypertension.

Abstract: This invention relates to certain inhibitors of lysyl oxidase and their use in the treatment of diseases and conditions associated with the abnormal deposition of collagen.
