Abstract: The present invention relates to a 2,7-substituted pyrrolo[2,1-f][1,2,4]triazine compound having a protein kinase inhibitory activity, a pharmaceutically acceptable salt thereof, and a pharmaceutical composition for the prevention, alleviation, or treatment of diseases induced by abnormal cell growth containing the compounds as active ingredients, and the novel cyclic 2,7-substituted pyrrolo[2,1-f][1,2,4]triazine compounds of the present invention exhibit excellent inhibitory effects on various protein kinases involved in growth factor signaling pathways. Therefore, they are useful as preventives, alleviators, or therapeutics for diseases characterized by abnormal cell growth induced by these protein kinases.

Abstract: The present invention relates to the use of a 2,3,5-substituted thiophene compound for the prevention, amelioration or treatment of gastrointestinal stromal tumor. The 2,3,5-substituted thiophene compound exhibits high inhibitory activity against the growth of gastrointestinal stromal tumor, and thus may be effectively used for the prevention, amelioration or treatment of gastrointestinal stromal tumor.

Abstract: Disclosed is a polypropylene resin composition having superior mechanical properties. More particularly, the polypropylene resin composition includes glass fiber and talc as fillers under an optimized condition and includes an ethylene-butene elastomer. The polypropylene resin composition exhibits no cracking, even when exposed to aromatic compounds or various chemicals, because of its superior chemical resistance, is easily processable because of its excellent mechanical properties such as impact strength, rigidity, etc., and is useful for use in automotive interior parts because of its superior scratch resistance, molding shrinkage, etc.
