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...
This paper reports the synthesis of 4-methoxymethyl and 4-acetoxymethyl-6,9-dimethyl-2H-thieno[3,2-g]-1-benzopyran-2-one as well as 4-methoxymethyl- and 4-acetoxymethyl-6,9-dimethyl-2H-thieno[2,3-h]-1-benzopyran-2-one. The synthesized derivatives were tested on human cells in UVA irradiation conditions. Skin phototoxicity and cross-link formation in DNA were also studied. Results indicate that...
