The present invention concerns the synthesis of compounds bearing the pyrrolo[2',3':3,4]cyclohepta[1,2-d]isoxazole structure, and their use for the treatment of pathologies having hyperproliferative features included those having neoplastic nature.
synthesized as a new class of tricyclic system in which the pyridine ring is annelated to a cycloheptapyrrole scaffold, with the aim of obtaining new photosensitizing agents with improved antiproliferative activity and lower undesired toxic effects. A versatile synthetic pathway was approached, which allowed the isolation of derivatives of the title ringsystem with a good substitution pattern on the
A new class of pyrrolo[2′,3′:3,4]cyclohepta[1,2-d][1,2]oxazoles was synthesized for the treatment of hyperproliferative pathologies, including neoplasms. The new compounds were screened in the 60 human cancer cell lines of the NCI drug screen and showed potent activity with GI50 values reaching the nanomolar level, with mean graph midpoints of 0.08–0.41 μM. All compounds were further tested on six
