Several nimesulide preparations (i.e., tablet form, gels) have been marketed, but no parenteral solution has achieved the market because of their low wettability and unsatisfactory chemical−physical properties required for parenteral use. In this paper we describe the synthesis of the nimesulide prodrug 1 and its anti-inflammatory and antihyperalgesic properties. Pharmacological studies, carried out
几种尼美舒利制剂(即片剂,凝胶剂)已经上市销售,但由于其低润湿性和肠胃外使用所需的化学-物理特性不令人满意,因此没有肠胃外解决方案能够进入市场。在本文中,我们描述了尼美舒利前药1的合成及其抗炎和抗痛觉过敏特性。进行药理研究以评估化合物1和尼美舒利的体内抗炎和镇痛活性,结果表明氨基磺酸钠1尼美舒利前药是一种有效的尼美舒利前药,可以通过肠胃外途径给药,经过令人满意的吸收并广泛转化为活性尼美舒利化合物。而且,在用化合物1大鼠处理后对尼美舒利的血浆浓度的评估显示尼美舒利的释放增加且呈剂量依赖性。相反,在“天然”药物给药后,尼美舒利的血浆浓度仍基本保持不变。这些初步结果促使人们对该药物作为肠胃外药物的候选药物进行进一步研究。
