Glioma is a brain tumor associated with a poor therapeutic outcome with an average life expectancy of 14 months. Cyclooxygenase‐2 (COX‐2) expression is associated with the progression of the tumor and is considered a therapeutic target of chemo agents. Para‐[18F]Fluorofenbufen octylamide ([18F]FFOA) was obtained with the radiochemical yield of 16% and specific activity of 4 GBq/μmol, and the IC50 values
脑胶质瘤是一种脑肿瘤,治疗效果差,平均预期寿命为14个月。环氧合酶2(COX-2)的表达与肿瘤的进展有关,被认为是化学药物的治疗靶标。获得对-[ 18 F]氟苯芬辛酰胺([ 18 F] FFOA),放射化学产率为16%,比活度为4 GBq /μmol,COX-1和COX-2的IC 50值为26.5和32.7。分别为μM。血浆冷FFOA的稳定性显着改善,半衰期为30分钟,吸收率[ 18根据脑肿瘤中3.9%注射剂量(ID / g)和脑中2.5%ID / g的积累确定,患有脑肿瘤的大鼠的F] FFOA为1.5。具有COX-2微摩尔亲和力的[ 18 F] FFOA可用于区分脑肿瘤和正常区域。
