  Synthesis, cytotoxicity and QSAR study of N-tosyl-1,2,3,4-tetrahydroisoquinoline derivatives

  摘要：

  利用改进的 Pictet-Spengler 反应合成了 1-取代-N-对甲苯磺酰基-1,2,3,4-四氢异喹啉类似物（4a-4l），并对其细胞毒性进行了评估。除对甲氧基类似物 4d 外，所有四氢异喹啉对 MOLT-3 细胞株都具有细胞毒性。有趣的是，邻羟基衍生物 4k 对 HuCCA-1、A-549 和 MOLT-3 细胞株的细胞毒性最强。在 MOLT-3 细胞中观察到的最低 IC50 值为 1.23 μM。三甲氧基类似物 4f 对 HepG2 的活性最强，其 IC50 值为 22.70 μM，低于参考药物依托泊苷。QSAR 研究表明，总对称性指数（Gu）、3D-MoRSE（Mor31v 和 Mor32u）和 3D Petitjean 指数（PJI3）是观察到的细胞毒性的最重要描述因子。对 MOLT-3 细胞毒性最强的化合物（4k）的 Gu 值最高，而无活性的对甲氧基类似物（4d）的 Gu 值最低。另一方面，分子质量最高的化合物（4f）对 HepG2 细胞的细胞毒性最强。这些研究表明，四氢异喹啉 4f 和 4k 可能是有趣的先导药性物质，值得进一步探索。QSAR 模型有助于深入了解所研究化合物的理化性质。

  An efficient, practical, and general method for conversions of N-tosyltetrahydroisoquinolines (N-tosyl-THIQs) into isoquinolines and of N-tosyltetrahydro-β-carbolines (N-tosyl-THBCs) into β-carbolines is described. Treatment of N-tosyl-THIQs or N-tosyl-THBCs with base in dimethyl sulfoxide afforded dihydroisoquinolines or dihydro-β-carbolines as intermediates, and these were then oxidized in situ by

  A Pd-catalyzed synthesis of 1,2,3,4-tetrahydroisoquinoline (THIQ) via cyclization of ortho-bromophenethyl tosylamides with aryl N-tosylhydrazones in the presence of base was developed. The reaction is believed to proceed via the oxidative addition of palladium with ortho-bromophenethyl tosylamides, followed by carbene insertion and cyclization. The carbene species were generated in-situ from the aryl

  1-Substituted-N-tosyl-1,2,3,4-tetrahydroisoquinoline analogs (4a–4l) were synthesized using the modified Pictet–Spengler reaction and evaluated for cytotoxicity. All tetrahydroisoquinolines displayed cytotoxicity against MOLT-3 cell lines, except for p-methoxy analog 4d. Interestingly, the o-hydroxy derivative 4k was shown to be the most potent cytotoxic against HuCCA-1, A-549 and MOLT-3 cell lines. The lowest IC50 value of 1.23 μM was observed for MOLT-3 cells. Trimethoxy analog 4f exerted the most potent activity against HepG2 with an IC50 of 22.70 μM, which is lower than the reference drug, etoposide. QSAR studies showed that total symmetry index (Gu), 3D-MoRSE (Mor31v and Mor32u) and 3D Petitjean index (PJI3) were the most important descriptors accounting for the observed cytotoxicities. The most potent cytotoxic compound (4k) against MOLT-3 had the highest Gu value, correspondingly the inactive p-methoxy analog (4d) had the lowest Gu value. On the other hand, the highest molecular mass compound (4f) was shown to be the most potent cytotoxic against HepG2 cells. The studies disclose that tetrahydroisoquinolines 4f and 4k are potentially interesting lead pharmacophores that should be further explored. The QSAR models provided insights into the physicochemical properties of the investigated compounds.
