摘要:
The present invention provides compounds of formula I and pharmaceutically acceptable salts thereof. The formula I compounds inhibit tyrosine kinase activity of Trk receptors such as TrkA, TrkB, TrkC or Flt-3 thereby making them useful as antiproliferative agents.
摘要:
The present invention provides compounds of formula (I): and pharmaceutically acceptable salts thereof. The compounds of the invention inhibit tyrosine kinase activity of growth factor receptors such as HER1, HER2 and HER4 thereby making them useful as antiproliferative agents. The compounds are also useful for the treatment of other diseases associated with signal transduction pathways operating through growth factor receptors.

摘要:
The present invention relates to a process of producing Ala-Gln dipeptide, comprising of: the amino acid protected at N-end reacts with triphenyl phosphine and hexachloroethane in an organic solvent, forming an active ester; the active ester reacts with glutamine in an organic solvent and an aqueous inorganic base solution, acidizing the result reaction mixture with an inorganic acid, deprotected the protection group at N-end. The raw materials are inexpensive. The synthesis process is not difficult. It is not necessary to separate the intermediate, or to purify it. It is easy to separate and purify the product. The reagents used in the process are less toxicity so that it is suit for environment.
