Acridine-based compounds possess anticanceractivities by intercalating to DNA. Although they have chemotherapeutic potential, acridine-based compounds are not used to treat cancer. In this study, 2,N10-acridone derivatives are designed and synthesized based on acridone, a ketone derivative of acridine. Herein, acridone is functionalized with alkyl sidechainscontaining terminal nitrogen-based moieties
吖啶类化合物通过嵌入 DNA 具有抗癌活性。尽管它们具有化学治疗潜力,但基于吖啶的化合物不用于治疗癌症。本研究以吖啶酮衍生物吖啶酮为基础,设计合成了2,N10-吖啶酮衍生物。在本文中,吖啶酮被烷基侧链官能化,该侧链在 N10 位含有末端氮基部分并在 C2 位被取代。评估产品对四种癌细胞系的体外细胞毒性:Molt-3、HepG2、A549 和 HuCCA-1。在 C2 和 N10 位带有两个丁基哌啶侧链的衍生物是最活跃的,IC50 值范围为 2.96 到 9.46 µM。分子建模研究支持衍生物通过嵌入与 DNA 结合,

N-Alkylation of aromatic compounds involving nitrogen heterocycles such as carbazole and acridone with alkyl halide in the presence of caustic solution and benzyl triethyl ammonium chloride (BTEAC) as a phase-transfer catalyst readily proceeded under mild conditions. These results show that this procedure is effective for the preparation of the title compounds in high yields.

During a structure–activity relationship optimization campaign to develop an inhibitor of AraC family transcriptional activators, we discovered an unexpected transformation of a previously reported inhibitor that occurs under the assay conditions. Once placed in the assay media, the 3,4-disubstituted dihydroquinoline core of the active analogue rapidly undergoes a decomposition reaction to a quaternary 3-substituted biquinolinium. Further examination established an SAR for this chemotype while also demonstrating its resilience to irreversible binding of biologically relevant nucleophiles.

cells than N,N'-dialkyl-9,9'-biacridylidenes 7-12, revealing that conjugation of the heteroaromatic system plays a significant role on the effective distribution of the compound in the intracellular environment. Cellular investigation of longalkyl derivatives against cell migration exhibited 40-50% wound healing effects and cytoplasm diffusion, while compounds with shorter alkylchains were accumulated
The Buchwald–Hartwigamination allows an efficient and convenient synthesis of biologically and pharmaceutically important acridones by formation of a six-membered ring. With the described method, a number of derivatives have been synthesized in up to 95% yield by using a variety of anilines as well as benzylic and aliphatic amines.
