Furocoumarins as multi-target agents in the treatment of cystic fibrosis

Abstract

Multi-target molecular entities, offer a path to progress both in understanding causes of disease and in defining effective small molecule treatments. Coumarin and its derivatives belong to an important group of natural compounds with diverse biological properties. They are found in vegetables and plants for which literature reports thousands of publications for the great variety of biological applications among which the photoprotective effects, thus being considered multi-targeting agents. Their furan condensed analogues constitute the family of furocoumarins, less represented in the literature, endowed with photosensitizing properties and often used for the treatment of skin diseases such as vitiligo and psoriasis. Despite the study of biological properties of linear and angular furocumarins dates back to ancient times, mainly as photosensitizers, these small molecules still represent an attractive scaffold for further development and applications in several therapeutic fields. The aim of the present review is to summarize the most promising chemical entities belonging to the class of furocumarins and coumarins, emerged in the last decades, and the methods used for their synthesis with a particular focus on main targets involved in the cystic fibrosis treatment.
