In this review we summarize the structure and biological effects of linear and angular psoralens. These compounds exhibit interesting biological effects on the cell cycle, apoptosis and differentiation. These molecules should be considered promising drugs in the therapy of several diseases, including psoriasis, mycosis fungoides and cancer. Also, preclinical data demonstrate a possible use of these molecules for the treatment of beta-thalassemia and other hematological disorders.

The aim of the present study was to identify molecular analogs of angelicin (ANG) able to increase erythroid differentiation of K562 cells and expression of gamma-globin genes in human erythroid precursor cells, with low effects on apoptosis. ANG-like molecules are well-known photosensitizers largely used for their antiproliferative activity in the treatment of different skin diseases (i.e., psoriasis, vitiligo, eczema, and mycosis fungoides). To verify the activity of these derivatives, we employed three experimental cell systems: (1) the human leukemic K562 cell line, (2) K562 cell clones stably transfected with a pCCL construct carrying green-EGFP under the gamma-globin gene promoter, and (3) the two-phase liquid culture of human erythroid progenitors isolated from normal donors and beta-thalassemia patients. The results of our study suggest that trimethyl ANG is a powerful inducer of erythroid differentiation, compared with known inducers, such as ANG, cytosine arabinoside, mithramycin, and cisplatin. These data could have practical relevance, because pharmacologically mediated regulation of human gamma-globin gene expression, with the consequent induction of fetal hemoglobin, is considered a potential therapeutic approach in hematological disorders including beta-thalassemia and sickle cell anemia.
