  2,4-Bis(octadecanoylamino)benzenesulfonic acid sodium salt as a novel scavenger receptor inhibitor with low molecular weight

  摘要：

  In order to investigate the effect of the fixation of the orientations of the two long chains, three types of novel derivatives of scavenger receptor inhibitor I were synthesized, and their biological activities were evaluated. Among the novel derivatives, 2,4-bis(octadecanoylamino)benzenesulfonic acid sodium salt (4d) showed the most potent inhibitory activity against the incorporation of 1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate-labeled acetyl-LDL (DiI-acetyl-LDL) into macrophages. 2,5-Bis(octadecanoylamino)benzenesulfonic acid sodium salt (4c), a regioisomer of 4d, did not exhibit as potent an inhibitory activity as 4d, meaning that the substitution pattern of two long chains on the benzene ring must be important. Compound Q exhibited 10 times more potent inhibitory activity against the binding of 121 I-labeled acetyl-LDL to the surface of macrophages than compound 1. (C) 2004 Elsevier Ltd.

  through small molecule inhibition of RAD51, thereby sensitizing tumor cells to DNA damaging irradiation and/or chemotherapy. Here we report structure-activity relationships for a library of quinazolinone derivatives. A novel RAD51 inhibitor (17) displays up to 15-fold enhanced inhibition of cell growth in a panel of TNBC cell lines compared to compound B02, and approximately 2-fold increased inhibition

  RAD51是同源重组DNA修复途径的重要组成部分，在耐药性癌症（包括侵袭性三阴性乳腺癌（TNBC））中过表达。提出的改善患者治疗效果的策略是通过小分子抑制RAD51，从而使肿瘤细胞对DNA破坏性辐射和/或化学疗法敏感。在这里，我们报告喹唑啉酮衍生物库的结构活性关系。与化合物B02相比，新型RAD51抑制剂（17）在一组TNBC细胞系中对细胞生长的抑制作用提高了15倍，对辐射诱导的RAD51灶形成的抑制作用则提高了约2倍。此外，化合物17 显着抑制TNBC细胞对DNA损伤的敏感性，这意味着潜在的靶向疗法可用于癌症治疗。
