  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.

Design of disease modifying multi target directed ligand (MTDL) has been performed, which disable PPI on the one hand and on the other hand, act as procognitive antagonists at the histamine H3 receptor (H3R). The synthetized compounds are structurally based on peptidomimetic amino acid-like structures mainly as keto, diketo-, or acyl variations of a piperazine moiety connected to
