We synthesized various 6-nitroquinazolines by modifying the structure of compound 1 and evaluated their inhibitory activities toward both TNF-α production and T cell proliferation responses. The presence of the unsubstituted piperazine ring at the C(7)-position was required for both inhibitory activities. In this series of compounds, 5d and 5f, containing the 4-fluorophenyl and 3,4-difluorophenyl moiety, respectively, at the C(4)-position, showed the suppressing effects toward both responses with low cell growth inhibition. Furthermore, the oral administration of these compounds mentioned above at doses of 30 and 100 mg/kg also resulted in significant inhibition of TNF-α production induced by LPS in vivo.
我们通过修改化合物1的结构合成了多种6-硝基喹唑啉,并评估了它们对TNF-α产生和T细胞增殖反应的抑制活性。在C(7)位上,需要存在未取代的哌嗪环才能发挥这两种抑制活性。在这一系列化合物中,5d和5f分别在C(4)位包含了4-氟苯基和3,4-二氟苯基,它们对这两种反应显示出抑制效果,同时对细胞生长的抑制较低。此外,口服给予上述化合物的剂量为30和100 mg/kg时,在体内也显著抑制了LPS诱导的TNF-α产生。
