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.

A novel bicyclic prostaglandin analogue, [1S-[1 alpha, 2 alpha (Z), 3 alpha, 4 alpha]]-7-[3-[[[[(1- Oxoheptyl)amino]acetyl]amino]-methyl]-7-oxabicyclo[2.2.1]hept-2- yl]-5-heptenoic acid [-)-7) was found to be a potent and selective thromboxane A2 (TxA2) receptor antagonist. Unlike the related series of omega-chain allylic alcohols, amide 7 and its congeners were uniformly free of direct contractile
<i>N</i>-Hydroxy Amides. II.<i>N</i>-Benzyloxy α-Amino Acid<i>N</i>-Hydroxysuccinimide Esters and Synthesis of a Hexapeptide Having an Alternating<i>N</i>-Hydroxy Amide–Amide Sequence
Acylation of a series of N-benzyloxy α-amino acid derivatives with N,N-phthaloyloglycine shows that the yield decreases with increasing bulkiness of the substituent even by the acyl chloride or mixed anhydride procedure, and that the use of an excess reagent or a double acylation technique is needed to attain a good yield. The low reactivity of the benzyloxyamino group enables us to utilize N-benzyloxy α-amino acid N-hydroxysuccinimide esters without N-protection in the acylation of the usual amino group. In an attempt to lengthen the chain of an N-hydroxy peptide, a hexapeptide anilide having an N-hydroxy-Dl-alanylglycyl sequence was synthesized via N-benzyloxy peptides. The complex forming tendency of the hexapeptide with iron(III) is examined.
