  • Publication number: 20220000840
    Abstract: The invention provides a pharmaceutical composition for injection comprising a NL-101 type compound and a preparation method thereof. The composition uses the NL-101 type compound as an active pharmaceutical ingredient, and the stability of the NL-101 type compound is improved by adding a chloride-containing stabilizing agent or using a co-solvent containing hydrochloric acid, so that the formulation can be stably produced and meet the requirements for clinical safe use.

  • Patent number: 9499530
    Abstract: A class of quinazoline derivatives or pharmaceutically acceptable salts or solvates thereof with novel structures is provided; meanwhile, a pharmaceutical composition comprising a pharmaceutically effective amount of said quinazoline derivatives or pharmaceutically acceptable salts or solvates thereof, and pharmaceutically acceptable excipients or additives is also provided. By modifying and transforming the quinazoline and screening of the transformed compounds on the activity of tyrosine kinase inhibition, most of the compounds have been found to possess inhibitory activity against one or several of EGFR, VEGFR-2, c-erbB-2, c-erbB-4, c-met, tie-2, PDGFR, c-src, lck, Zap70 and fyn kinases. The present invention has the advantages of reasonable design, broad source of and easy access to the raw materials, simple and easy operation of the preparation methods, mild reaction conditions, high yield of the products and being beneficial for industrial-scale production.
