Design, Synthesis, and Pharmacological Evaluation of Novel Hybrid Compounds To Treat Sickle Cell Disease Symptoms
摘要:
A novel series of thalidomide derivatives (4a-f) designed by molecular hybridization were synthesized and evaluated in vitro and in vivo for their potential use in the oral treatment of sickle cell disease symptoms. Compounds 4a-f demonstrated analgesic, anti-inflammatory, and NO-donor properties. Compounds 4c and 4d were considered promising candidate drugs and were further evaluated in transgenic sickle cell mice to determine their capacity to reduce the levels of the proinflammatory cytokine tumor necrosis factor alpha (TNF alpha). Unlike hydroxyurea, the compounds reduced the concentrations of TNF alpha to levels similar to those induced with the control dexamethasone (300 mu mol/kg). These compounds are novel lead drug candidates with multiple beneficial actions in the treatment of sickle cell disease symptoms and offer an alternative to hydroxyurea treatment.

The present invention refers to the use of phthalimide and/or sulphonamide derivatives with nitric oxide donor properties, which have important activities in increasing the gamma-globin gene expression and anti-inflammatory and analgesic activities, effective in the treatment of hematologic diseases which require reducing the TNF-α levels and an exogenous source of nitric oxide. More particularly, the present invention describes the use of such phthalimide and/or sulphonamide derivatives for the treatment of sickle-cell disease. The invention also has as a novel characteristic the disclosure of new functionalized phthalimide derivatives designed from the prototypes thalidomide and hydroxyurea, and designed rationally through the strategy of molecular hybridization for the treatment of said diseases. The invention still discloses a new method for obtaining a specific sulphonamide derivative which can be used in the preparation of a drug for the treatment of diseases which require reducing the levels of the TNF-α factor and an exogenous source of nitric oxide.
