pancreatic, lung and colorectal cancers, thereby representing a relevant target for the treatment of these diseases. The KRAS P1 promoter contains a nuclease hypersensitive, guanine-rich sequence able to fold into a G-quadruplex motif (G4). The stabilization of this G4 structure by small molecules is emerging as a feasible approach to downregulate KRAS expression. Here, a set of novel stabilizing molecules

The synthesis of benzimidazoquinazoline derivatives bearing different alkylamino side chains is reported. All new compounds tested by means of an in vitro assay exhibit. antiproliferative activity toward human tumor cell lines. The cytotoxic effect depends on the type of side chain inserted in the planar nucleus and in some cases it is comparable to that of the well-known drug ellipticine. In order to understand the mechanism of action of these compounds, the interaction with DNA has been investigated. Linear flow dichroism measurements allowed us to verify the formation of a molecular complex with DNA and the corresponding geometry of interaction. Intrinsic binding constants have also been evaluated by performing fluorimetric titrations. (C) 2001 Elsevier Science S.A..All rights reserved.

The synthesis of new derivatives of the planar tricyclic pyrimido[1,2-a]benzimidazole system featuring protonable sidechains in the 3 and/or 10 positions is described. The reported literature procedures for the preparation of the intermediate 3-ethoxycarbonylpyrimido[1,2-a]benzimidazol-4(10H)-one 15, starting from 2-aminobenzimidazole 18 and diethyl ethoxymethylenemalonate, were revised. The interaction
