摘要:
The present invention relates to a crystalline form of 2-(2-hydroxyphenyl) benz [e] [1, 3] oxazin-4-one, a process for production thereof and its use in the preparation of 4- (3, 5-bis (2-hydroxyphenyl)-1H-1, 2, 4-triazol-1-yl) benzoic acid. The improved process for the preparation 4-(3,5-bis (2-hydroxyphenyl)-1H-1,2,4-triazol-1-yl) benzoic acid (Deferasirox), wherein salicylic chloride is reacted with salicylamide in presence of a solvent to give acyl compound, which is heated to higher temperature in-situ to undergo cyclization to obtain crystalline form of 2-(2-hydroxyphenyl) benz [e] [1, 3] oxazin-4-on and further reaction with hydrazino benzoic acid to give 4-(3,5- bis(2-hydroxyphenyl)-1H-1,2,4-triazol-1-yl)benzoic acid.

摘要:
The present invention relates to novel ultraviolet light absorbers of the benzoxazinone, oxanilide, benzylidene malonate, quinazoline and benzotriazole classes. The invention also relates to polymer and photographic compositions stabilized against the deleterious effects of light induced degradation which comprise the novel ultraviolet light absorbers.
摘要:
Novel fluorescent derivitization reagents are described that are suitable for coupling to biomolecules that contain aldehyde or ketone functional groups. The method of treating a sample with the derivativization reagents is described. The reagents are particularly useful for labeling glycoproteins or glycopeptides, nucleic acids, and lipopolysaccharides in electrophoresis gels.
摘要:
The use of compounds of general formula (I) as factor VII-tissue factor inhibitors as well as novel benzoaxin derivatives are disclosed. The compounds of general formula (I) and pharmaceutical acceptable salts thereof have been shown to be inhibitors of factor VIIa-tissue factor activity. The compounds show anticoagulant properties. The compounds are useful for the treatment of deficiencies of blood clotting factors or the effects of inhibitors to blood clotting factors. Methods for inhibiting clotting activity are disclosed.
摘要:
Compounds represented by general formula (I) and pharmacologically acceptable salts and solvates thereof. The compounds inhibit the biosynthesis of triglycerides in the liver and also inhibit the secretion of lipoproteins containing apolipoprotein B from the liver. They are hence useful for the prevention/treatment of hyperlipemia (especially hyper-VLDL-emia) and diseases caused thereby, such as arteriosclerotic diseases, e.g., myocardial infarct, and pancreatitis. Wherein A represents -CR R -(CH2)i- (wherein R and R each represents hydrogen or alkyl), -CH=CH-, -O-CH2-, or -S(O)j-CH2-; B represents hydrogen or halogen; X represents -CR R R , -NR R , -(CH2-CH=C(CH3)-CH2)p-CH2CH=C(CH3)2, alkyl, cycloalkyl, phenyl, cinnamyl, or heteroaryl; Y represents -(CH2)q-, -CH=CH-, -NR -, oxygen, or a bond; Z represents carbonyl or a bond; K represents alkylene or a bond; L represents -CH=CH- or a bond; and M represents hydrogen, alkyl, cycloalkyl, phenyl, heterocycle, biphenyl, or diphenymethyl.
