Synthesis and anti-inflammatory effects of certain furo[3′,2′:3,4]naphtho[1,2-d]imidazole derivatives 12–18 were studied. These compounds were synthesized from naphtho[1,2-b]furan-4,5-dione (10) which in turn was prepared from the known 2-hydoxy-1,4-naphthoquinone (7) in a one pot reaction. Furo[3′,2′:3,4]naphtho[1,2-d]imidazole (12) was inactive (IC50 value of >30 μM) while its 5-phenyl derivative 13
合成和某些呋喃并抗炎作用[3',2':3,4]萘并[1,2- d ]咪唑衍生物12 - 18进行了研究。这些化合物是由萘并[1,2 - b ]呋喃-4,5-二酮(10)合成的,后者又由已知的2-羟基-1,4-萘醌(7)在一锅反应中制备。呋喃并[3',2':3,4]萘并[1,2- d ]咪唑(12)处于非活性状态(IC 50值> 30μM),而其5-苯基衍生物13的IC 50为溶菌酶和β-葡萄糖醛酸苷酶释放的分别为16.3和11.4μM的值与阳性三氟哌嗪相当。对于5-呋喃衍生物16观察到了相同的效力,其IC 50值分别为19.5和11.3μM,可抵抗溶菌酶和β-葡萄糖醛酸苷酶的释放。如在14和17的情况下,在5-苯基或5-呋喃基上取代的吸电子NO 2导致缺乏活性。其中,化合物15表现出显着的抑制作用,对溶菌酶和β-葡萄糖醛酸苷酶释放的IC 50值分别为7.4和5.0μM。 对于LPS诱导的N
