In this paper we report the design, synthesis, antinociceptive and anti-inflammatory activities of a series of benzothiazine N-acylhydrazones 14a–h, planned by structural modification of piroxicam (1), a non steroidal anti-inflammatory drug. Among the synthesized analogues, compounds 14f (LASSBio-1637) and 14g (LASSBio-1639) were identified as novel antinociceptive and anti-inflammatory prototypes, active by oral administration, acting by a mechanism of action that seems to be different from that of piroxicam, since they were inactive as an inhibitor of cyclooxygenase (COX-1 and COX-2) at concentrations of 10 mM.
本文报告了一系列苯并噻嗪 N-酰肼 14a-h 的设计、合成、抗痛觉和抗炎活性,这些化合物是通过对非甾体抗炎药物吡罗昔康 (1) 进行结构改造而设计的。在合成的类似物中,化合物 14f (LASSBio-1637) 和 14g (LASSBio-1639) 被确定为新型抗痛觉和抗炎原型,口服具有活性,其作用机制似乎不同于吡罗昔康,因为它们在 10 毫摩尔浓度下作为环氧化酶(COX-1 和 COX-2)抑制剂没有活性。
