  New pharmaceutical compounds of general formula (I): F-(X)q where q is an integer from 1 to 5, preferably 1; -F is chosen among drugs described in the text, -X is chosen among 4 groups -M, -T, -V and -Y as described in the text. The compounds of general formula (I) are nitrate prodrugs which can release nitric oxide in vivo in a controlled and selective way and without hypotensive side effects and for this reason they are useful for the preparation of medicines for prevention and treatment of inflammatory, ischemic, degenerative and proliferative diseases of musculoskeletal, tegumental, respiratory, gastrointestinal, genito-urinary and central nervous systems.

  通式（I）的新药物化合物：F-（X）q，其中q是1到5的整数，最好是1；-F是在文本中描述的药物中选择的，-X是在文本中描述的4个组-M，-T，-V和-Y中选择的。通式（I）的化合物是硝酸盐前药，可以在体内以受控和选择性的方式释放一氧化氮，而不会产生降压副作用，因此它们非常适用于制备用于预防和治疗肌肉骨骼，皮肤，呼吸，消化，泌尿和中枢神经系统的炎症，缺血，退行性和增生性疾病的药物。
