Die Erfindung betrifft durch Chinazolin, Chinoxalin, Cinnolin, Indazol, Phthalazin, Naphthyridin, Benzothiazol, Dihydroindolon, Dihydroisoindolon, Benzimidazol oder Indol substituierte Pentanolderivate der allgemeinen Formel (I) ein Verfahren zu ihrer Herstellung und ihre Verwendung als Entzündungshemmer.
The present invention describes 2-methyl-quinazoline compounds of general formula (I), methods of preparing said compounds, intermediate compounds useful for preparing said compounds, pharmaceutical compositions and combinations comprising said compounds, and the use of said compounds for manufacturing pharmaceutical compositions. The 2-methyl substituted quinazoline compounds of general formula(I) effectively and selectively inhibit the Ras-Sos interaction without significantly targeting the EGFR receptor. They are therefore useful for the treatment or prophylaxis of diseases, in particular of hyperproliferative disorders, such as cancer as a sole agent or in combination with other active ingredients.
Novel compounds useful for inhibiting the 90 kDa heat shock proteins containing a quinone-like moiety and a di-hydroxy phenol like moiety, similar to geldanamycin and radicicol.
The invention provides compounds of the formula:
