Electrophilic fluorine-mediated dearomative spirocyclization has been developed to synthesize a range of fluoro-substituted spiro-isoxazoline ethers and lactones. The in vitro biological assays of synthesized compounds were probed for anti-viral activity against human cytomegalovirus (HCMV) and cytotoxicity against glioblastomas (GBM6) and triple negative breast cancer (MDA MB 231). Interestingly,
亲电氟介导的脱芳香螺环化已被开发用于合成一系列氟取代的螺异恶唑啉醚和内酯。对合成化合物进行体外生物学测定,探讨其对人巨细胞病毒 (HCMV) 的抗病毒活性以及对胶质母细胞瘤 (GBM6) 和三阴性乳腺癌 (MDA MB 231) 的细胞毒性。有趣的是,化合物4d和4n显示出显着的抗HCMV活性(IC 50 ∼ 10 μM),而4l和5f显示出最高的细胞毒性,IC 50 = 36 〜 80 μM。合成功效和生物学相关性为进一步开发氟螺螺异恶唑啉作为新型抗病毒和抗癌药物提供了机会。
