  NO-releasing STAT3 inhibitors suppress BRAF-mutant melanoma growth

  摘要：

  Constitutive activation of STAT3 can play a vital role in the development of melanoma. STAT3-targeted therapeutics are reported to show efficacy in melanomas harboring the BRAFV600E mutant and also in vemurafenib-resistant melanomas. We designed and synthesized a series of substituted nitric oxide (NO)-releasing quinolone-1,2,4-triazoleioxime hybrids, hypothesizing that the introduction of a STAT3 binding scaffold would augment their cytotoxicity. All the hybrids tested showed a comparable level of in vitro NO production. 7b and 7c exhibited direct binding to the STAT3-SH domain with IC50 of similar to 0.5 mu M. Also, they abrogated STAT3 tyrosine phosphorylation in several cancer cell lines, including the A375 melanoma cell line that carries the BRAFV600E mutation. At the same time, they did not affect the phosphorylation of upstream kinases or other STAT isoforms. 7c inhibited STAT3 nuclear translocation in mouse embryonic fibroblast while 7b and 7c inhibited STAT3 DNA-binding activity in the A375 cell line. Their anti-proliferating activity is attributed to their ability to trigger the production of reactive oxygen species and induce G1 cell cycle arrest in the A375 cell line. Interestingly, 7b and 7c showed robust cell growth suppression and apoptosis induction in two pairs of BRAF inhibitor-naive (-S) and resistant (-R) melanoma cell lines containing a BRAF V600E mutation. Surprisingly, MEL1617-R cells that are known to be more resistance to MEK inhibition by GSK1120212 than MEL1617-S cells exhibit a similar response to 7b and 7c. (C) 2019 Elsevier Masson SAS.

  新型喹啉/查尔酮杂化物作为抗癌剂：细胞毒性和PI3K抑制活性的设计，合成和评估。

  摘要：

  设计了一系列喹啉-查耳酮杂化物作为潜在的抗癌药，进行了合成和评估。不同的细胞毒性试验表明，化合物具有良好的活性。化合物9i和9j对所有测试的A549和K-562细胞的IC50 = 1.91-5.29 µM的细胞系最有效。从机理上讲，9i和9j诱导了A549和K562细胞的G2 / M细胞周期停滞和凋亡。此外，当针对两种提及的化合物进行测试时，所有PI3K亚型均被非选择性抑制，IC50为52-473 nM，其中9i对PI3K-γ最有效（IC50 = 52 nM）。9i和9j的对接显示可能在PI3K-γ同工型的活性位点与基本缬氨酸残基形成H键。同时，Western印迹分析显示9i和9j抑制了PI3K，Akt，mTOR，以及A549和K562细胞中的GSK-3β，提示阻断PI3K / Akt / mTOR途径与上述抗肿瘤活性相关。总之，我们的发现通过抑制PI3K / Akt / mTOR途径，支

  In continuation of our study of novel quinolines with anti-inflammatory activity using the Pfitzinger reaction, several new quinoline derivatives were synthesized and tested for their anti-inflammatory and ulcerogenic effect. A docking study on the COX-2 binding pocket was carried out for the target compounds to rationalize the possible selectivity of them against COX-2 enzyme. The most active compounds
