摘要:
Described is a new process for producing temozolomide, comprising the reaction between 5-aminoimidazole-4-carboxamide and N-succinimidyl-N′-methyl carbamate and the subsequent reaction of the thus obtained carbamoyl 5-aminoimidazole-4-carboxamide with sodium nitrite. Temozolomide is then purified by chromatography on adsorbent polymeric resin and subsequent crystallization from water and acetone.

The invention relates to a compound of formula wherein R1, R2, X, L, W, n, and o are defined herein and to pharmaceutically suitable acid addition salts thereof, with the exception of the following compounds 6-(4-methyl-piperazin-1-yl)-N-phenethyl-nicotinamide (CAS 199478-31-4), N-(3,4-dichloro-benzyl)-3-fluoro-benzamide (CAS 424815-98-5), N-(4-chloro-benzyl)-3-fluoro-benzamide (CAS 544661-83-8), N-(3-chloro-benzyl)-3-fluoro-benzamide (CAS 796051-07-5), and N-phenethyl-6-phenylamino-nicotinamide (CAS 571913-74-1). The compounds of formula I have a good affinity to the trace amine associated receptors (TAARs), especially for TAAR1 and are useful for the treatment of CNS disorders.
摘要:
A novel selenium-containing compound, a method of producing the selenium-containing compound, an analysis method using the selenium-containing compound, and use of the selenium-containing compound as an antioxidant, are disclosed. A novel selenium-containing compound shown by any of chemical formulas 1 to 4 is obtained by extracting a selenium-containing compound from a sample using an organic solvent or water, and purifying the selenium-containing compound. The novel selenium-containing compound may be used for a novel analysis method, or may be used as an antioxidant.
摘要:
The present invention provides a process for the preparation of imidazoles by reacting a cyano compound with a silylalkylisocyanide compound. Such imidazoles are useful pharmacologically-active compounds and/or intermediates for the preparation of pharmacologically-active compounds.
摘要:

摘要:
This invention describes novel tricyclic-bis-enone derivatives (TBEs), such as TBE-31, TBE-34, TBE-45 and water-soluble TBEs. The methods of preparing these compounds are also disclosed. The inventors demonstrate the ability of these new TBEs to inhibit proliferation of human myeloma cells, inhibit the induction of iNOS in cells stimulated with interferon-γ, induce heme oxygenase-1 (HO-1), induce CD11b expression—a leukemia differentiation marker, inhibit proliferation of leukemia cells, induce apoptosis in human lung cancer, and induce apoptosis in other cancerous cells. The TBEs of this invention are expected to be useful agents for the treatment and prevention of many diseases, including cancer, neurological disorders, inflammation, and pathologies involving oxidative stress.
