The present invention concerns the synthesis of new analogs of angelicins, pyrrolo [3,2-h]quinoline, for the treatment of pathologies having hyperproliferative character included those having neoplastic nature. The treatment is based on the combined action of pyrrolo [3,2-h]quinolines and UV-A light, through a clinical approach defined as PUVA (psoralen-UVA light). The most important feature of these compounds is that they exert their remarkable photoxicity without any DNA damage, which is the main origin of the side effects of the PUVA therapy.
In the search for newphotochemotherapeuticagents, a series of derivatives of the ring system pyrrolo[3,2-h]quinoline—bioisosters of the angular furocoumarin angelicin—were synthesized through a four-step synthetic approach, in reasonable overall yields. Eight of the synthesized derivatives showed a remarkable phototoxicity against a panel of four human tumor cell lines and a great dose UV-A dependence
