Some novel α,β-unsaturated aromatic sulfone analogs (5a–5m) and their Tempol conjugates (6a–6e) have been synthetically prepared, characterized and evaluated for their radioprotective activity under γ-ray radiation. The Tempol conjugates were characterized by X-ray single crystal diffraction. In vitro studies showed that 5a, 5b and 6b had superior activities to Ex-Rad pre-treated before 5 Gy irradiation
已经合成了一些新颖的α,β-不饱和芳族砜类似物(5a-5m)和它们的Tempol共轭物(6a-6e),表征并评估了它们在γ射线辐射下的辐射防护活性。Tempol共轭物通过X射线单晶衍射进行表征。体外研究表明,5a,5b和6b的活性优于5Gy辐照前的Ex-Rad,5a,6a和6b的活性比5Gy辐照后的Ex-Rad更好,而5a,6a和6b同时显示出预防和缓解作用,表明将α,β-不饱和芳族砜与Tempol氮氧化物结合使用的优势。在化合物处理的细胞中,p53和磷酸化p53的水平均显着低于未处理的辐照细胞。缀合物提供改善的放射防护能力,这是治疗方案中的优点。
