检测炎症生物标志物(例如环氧合酶-2 (COX-2))的临床成像方法可能有助于炎症性疾病的诊断和治疗。为此,我们报告了N-[(罗丹明-X-基)丁-4-基]-2-[1-(4-氯苯甲酰基)-5-甲氧基-2-甲基-1H-吲哚-3-基]乙酰胺氯化盐(氟考昔布D)的发现,氟考昔布D是氟考昔A的亲水类似物。氟考昔布D在纯化的酶制剂和细胞中选择性抑制COX-2。它表现出足够的光物理特性,能够在角叉菜胶诱导的急性足垫炎症小鼠模型和骨关节炎小鼠模型炎症中检测完整细胞中的 COX-2。 COX-2 选择性通过用塞来考昔阻断酶的活性位点或通过使用非靶向 5-羧基-X-罗丹明染料进行分子成像来验证。这些数据表明,氟考昔 D 是早期检测 COX-2 水平升高的炎症或肿瘤病变的理想候选药物。
Clinical imaging approaches to detect inflammatory biomarkers, such as cyclooxygenase-2 (COX-2), may facilitate the diagnosis and therapy of inflammatory diseases. To this end, we report the discovery ofN-[(rhodamin-X-yl)but-4-yl]-2-[1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-yl]acetamide chloride salt (fluorocoxib D), a hydrophilic analog of fluorocoxib A. Fluorocoxib D inhibits COX-2 selectively in purified enzyme preparations and cells. It exhibits adequate photophysical properties to enable detection of COX-2 in intact cells, in a mouse model of carrageenan-induced acute footpad inflammation and inflammation in a mouse model of osteoarthritis. COX-2-selectivity was verified either by blocking the enzyme’s active site with celecoxib or by molecular imaging with nontargeted 5-carboxy-X-rhodamine dye. These data indicate that fluorocoxib D is an ideal candidate for early detection of inflammatory or neoplastic lesions expressing elevated levels of COX-2.
