New series of furosalicylic acids 3a—c, furosalicylanilides 6a—n, furobenzoxazines 8a—f, 1-benzofuran-3-arylprop-2-en-1-ones 12a,b, 6-(aryl-3-oxoprop-1-enyl)-4H-chromen-4-ones 16a—c and 6-[6-aryl-2-thioxo-2,5-dihydropyrimidin-4-yl]-4H-chromen-4-ones 17a—c were synthesized. Anti-inflammatory activity evaluation was performed using carrageenan-induced paw edema model in rats and prostaglandin E2 (PGE2) synthesis inhibition activity. Some of the tested compounds revealed comparable activity with less ulcerogenic effect than Diclofenac at a dose 100 mg/kg. All the synthesized compounds were docked on the active site of cyclooxygenase-2 (COX-2) enzyme and most of them showed good interactions with the amino acids of the active site comparable to the interactions exhibited by Diclofenac.
合成了新系列的呋喃水杨酸 3a-c、呋喃水杨酰苯胺 6a-n、呋喃苯并恶嗪 8a-f、1-苯并呋喃-3-芳基丙-2-烯-1-酮 12a,b、6-(芳基-3-氧代丙-1-烯基)-4H-色烯-4-酮 16a-c 和 6-[6-芳基-2-硫酮-2,5-二氢嘧啶-4-基]-4H-色烯-4-酮 17a-c。使用卡拉胶诱导的大鼠爪水肿模型和前列腺素 E2(PGE2)合成抑制活性进行了抗炎活性评估。在剂量为 100 毫克/千克时,一些受测化合物的活性与双氯芬酸相当,且致溃作用较小。所有合成的化合物都与环氧合酶-2(COX-2)酶的活性位点对接,其中大多数化合物与活性位点的氨基酸之间表现出良好的相互作用,与双氯芬酸表现出的相互作用相当。
