摘要:
Pure -1,2,3,9-tetrahydro-9-methyl-3-[(2-methyl-1H-imidazol-1-yl)methyl]-4H-carbazol-4-one or a pharmaceutically acceptable salt thereof is prepared in a high yield by a simple process which reacts 1,2,3,9-tetrahydro-9-methyl-4H-carbazol-4-one with a 2-methylimidazole derivative in an organic solvent or in a mixture of an organic solvent and water in the presence of a halosilane compound.
摘要:
The present invention provides a novel amide derivative and a pharmaceutically acceptable salt thereof which selectively and effectively inhibits the growth of cancer cells induced by the overexpression of an epidermal growth factor receptor and also prevents the development of drug resistance caused by the mutation of EGFR tyrosine kinase, and a pharmaceutical composition comprising same as an active ingredient.
摘要:
The present invention elates to a process for preparing paclitaxel represented by formula (1) characterized in that: (a) an oxazolidine derivative represented by formula (2) or its salt in which X represents halogen, is coupled with a 7-trihaloacetyl-baccatin III represented by formula (3) in which R.sub.1 represents trihaloacetyl, in a solvent in the presence of a condensing agent to produce an oxazolidine substituent-containing taxane represented by formula (4) in which X and R.sub.1 are each as previously defined; (b) the oxazolidine ring is opened in a solvent in the presence of an acid, and the product thus obtained is reacted with benzoyl chloride in the presence of a base to produce a protected paclitaxel wherein the hydroxy group at 7-position is protected with trihaloacetyl group represented by formula (5) in which R.sub.1 is as previously defined; (c) then the protecting group at 7-position is removed by ammonia or a salt of ammonia with a weak acid in a solvent.
