    We report here the synthesis of novel thymine biomimetic photo-adducts bearing an alkane spacer between nucleobases and characterized by antimelanoma activity against two mutated cancer cell lines overexpressing human Topoisomerase 1 (TOP1), namely SKMEL28 and RPMI7951. Among them, Dewar Valence photo-adducts showed a selectivity index higher than the corresponding pyrimidine-(6-4)-pyrimidone and cyclobutane counterpart and were characterized by the highest affinity towards TOP1/DNA complex as evaluated by molecular docking analysis. The antimelanoma activity of novel photo-adducts was retained after loading into UV photo-protective lignin nanoparticles as stabilizing agent and efficient drug delivery system. Overall, these results support a combined antimelanoma and UV sunscreen strategy involving the use of photo-protective lignin nanoparticles for the controlled release of thymine dimers on the skin followed by their sacrificial transformation into photo-adducts and successive inhibition of melanoma and alert of cellular UV machinery repair pathways.

    我们在此报告合成了一种新型嘧啶生物模拟光附加物,其在核碱基之间带有烷基间隔,并对过表达人类拓扑异构酶1(TOP1)的两种突变癌细胞系SKMEL28和RPMI7951表现出抗黑色素瘤活性。其中,Dewar价态光附加物的选择性指数高于相应的嘧啶-(6-4)-嘧啶酮和环丁烷对应物,并通过分子对接分析评估了其与TOP1/DNA复合物之间的最高亲和力。新型光附加物的抗黑色素瘤活性在载入UV光保护木质素纳米粒子作为稳定剂和高效药物输送系统后得以保留。总体而言,这些结果支持一种结合抗黑色素瘤和UV防晒策略,涉及使用光保护木质素纳米粒子对皮肤上的胸腺嘧啶二聚体进行控制释放,随后将其牺牲性转化为光附加物,并连续抑制黑色素瘤和警觉细胞UV机制修复途径。
