(COX‐2)‐specific fluorescent cancer biomarkers were synthesized by linking the anti‐inflammatory drugs ibuprofen, (S)‐naproxen, and celecoxib to the 7‐nitrobenzofurazan (NBD) fluorophore. In vitro COX‐1/COX‐2 inhibition studies indicated that all of these fluorescent conjugates are COX‐2 inhibitors (IC50 range: 0.19–23.0 μM) with an appreciable COX‐2 selectivity index (SI≥4.3–444). In this study the celecoxib–NBD
通过将抗炎药布洛芬,(S)-萘普生和塞来昔布与7-硝基苯并呋喃山(NBD)荧光团连接,合成了一组特定于环氧合酶2(COX-2)的荧光癌生物标记。体外COX-1 / COX-2抑制的研究表明,所有这些荧光缀合物的是COX-2抑制剂(IC 50范围:0.19-23.0μ中号)与可感知的COX-2选择性指数(SI≥4.3-444)。在这项研究中,塞来昔布-NBD共轭N-(2-((7-硝基苯并[ c ] [1,2,5]恶二唑-4-基)氨基)乙基)-4-(5-(对甲苯基)- 3-(三氟甲基)-1 H-吡唑-1-基)苯磺酰胺(14),其显示的最高COX-2抑制的效力和选择性(COX-2的IC 50 = 0.19μ中号;使用COX-SI = 443.6),被认定为即将发生的COX-2特异性的生物标记用于癌症的荧光成像2表达人类结肠癌细胞系(HCA-7)。
