摘要:
Compounds which are active against viruses have Formulas (1, 2, 3 and 4) wherein B is a purine or pyrimidine heterocyclic ring and is preferably selected from the group consisting of 6-aminopurine (adenine), 2,6-diaminopurine, 2-amino-6-azidopurine, 2-amino-6-cyclopropylaminopurine, 6-hydroxypurine (hypoxanthine), 2-amino-6-halo substituted purines, 2-amino-6-alkoxy substituted purines, 2-amino-6-hydroxypurine (guanine), 3-deazapurines, 7-deaza-purines, 8-azapurines, cytosine, 5-halo substituted cytosines, 5-alkyl substituted cytosines, thymine, uracil and 6-azapyrimidines; X is O; and, R1 and R2 are alkyl or aryl groups. The compounds of the present invention also include the R- and S-enantiomers of the above compounds. The R1X and/or R2X can also be amino acid residues with X as NH.
摘要:
Compositions and methods of use for treating hepatitis C virus-infected mammals are disclosed. The compositions include one or more thymosins alone or in combination with one or more interferons. Methods of treatment include use of thymosins alone, or together, or sequentially with interferon.
摘要:
Stable, enzymatically triggered chemiluminescent 1,2-dioxetanes with improved water solubility are provided. Dioxetanes further substituted with two or more water-solubilizing groups disposed on the dioxetane structure provide superior performance by eliminating the problem of reagent carryover when used in assays performed on capsule chemistry analytical systems. Compositions comprising a dioxetane with two or more water-solubilizing groups, a non-polymeric cationic surfactant enhancer and optionally a fluorescer, for providing enhanced chemiluminescence are also provided.
摘要:
A method and composition for treating a Hepatitis B patient having hepatic decompensation utilizes Hepatitis B virus-reducing amounts of T alpha 1, administered to a patient having decompensated liver disease so as to render the patient seronegative for Hepatitis B virus DNA.
摘要:
A method of treating Hepatitis C by administering an immune system-potentiating dose of at least one Thymosin or system-potentiating Thymosin fragment to a mammal infected with Hepatitis C virus, which Hepatitis C infection in the mammal is non-responsive to treatment with interferon alone.
摘要:
Dioxetanes which couple with organic and biological molecules of the formula:
wherein X is a leaving group which is removed by an activating agent to produce light, wherein A is a coupling substituent, Ar is a substituent selected from the group consisting of phenyl and naphthyl to provide a label are described. R₁ is an optional linker substituent and can have between 1 and 30 carbon atoms with some of the carbon atoms being oxygen, sulfur, nitrogen or phosphorus. Ar as phenyl is preferred. The dioxetane coupled molecules are useful in assays of all types where luminescence can be used as an indicator.
摘要:
Shaped synthetic diamond articles are fabricated by vapour deposition of synthetic diamond on releasable moulds. A process is also provided for forming a shaped synthetic diamond article by coating a mould with an etchable layer and then depositing synthetic diamond on the etchable layer; the etchable layer is thereafter removed in an etchant bath, releasing the diamond article from the mould. The synthetic diamond articles are useful as high-temperature, corrosion resistant vessels and as wear surfaces.
摘要:
The use of calcium channel blocker compounds as antitumor and antimetastatic agents in mammals in vivo and in standard laboratory experiments with tumor cells in vitro is described. In particular the use of nimodipine (Bay e 9736) or nifedipine (Bay a 1040) and structurally related compounds as described.
