Design and synthesis of furoxan-based nitric oxide-releasing glucocorticoid derivatives with potent anti-inflammatory activity and improved safety

Abstract

A series of furoxan-based nitric oxide-releasing glucocorticoid derivatives was synthesized. The pharmacological assays indicated that three compounds, including I(4), I(5), and I(6), had anti-inflammatory activity. Furthermore compared with the leading compound hydrocortisone the safety of I(6) was greatly improved. Due to releasing NO in vivo the side effects of glucocorticoids, including hypertension and osteoporosis, were effectively avoided.
