methylsulfone group. The potential of this methodology has been demonstrated by the successful radiosynthesis of carbon-11 analogues of several highly selective cyclooxygenase-2 (COX-2) inhibitors such as Rofecoxib, Etoricoxib, and 3-(4-methylsulfonylphenyl)-4-phenyl-5-trifluoromethyl isoxazole in high yield. The chemical and radiochemical purities obtained for the 11C-labeled COX-2 inhibitors are >99%
已经开发了一种通用的一锅法,用于将被掩蔽为丁酸酯的芳基硫醇部分转化为相应的11C-标记的甲基砜基团。这种方法的潜力已通过成功放射性合成几种高选择性环氧合酶2(COX-2)抑制剂(如罗非考昔,依托昔布和3-(4-甲基磺酰基苯基)-4-苯基-5)的11碳类似物得到了证明。 -三氟甲基异恶唑,收率高。11C标记的COX-2抑制剂获得的化学和放射化学纯度> 99%,比活度> 1000 Ci / mmol。
