Novel type 1 phototherapeutic agents based on compounds containing S–N bonds (sulfenamides) were synthesized, assessed for free radical generation, and evaluated in vitro for cell death efficacy in four cancer cell lines (U937, HTC11, KB, and HT29). All of the compounds were found to produce copious free radicals upon photoexcitation with UV-A and/or UV-B light, as determined by electron spin resonance
合成了基于含有 S-N 键的化合物(次磺酰胺)的新型 1 型光治疗剂,评估了自由基的产生,并在体外评估了四种癌细胞系(U937、HTC11、KB 和 HT29)的细胞死亡功效。经电子自旋共振光谱测定,发现所有化合物在用 UV-A 和/或 UV-B 光进行光激发时都会产生大量自由基。在所有四种癌细胞系中,次磺酰胺中最有效的化合物来自二苯并氮杂7b和二氢吖啶8b。
