Abstract
An effective and straightforward method for the synthesis of 1-aminoanthracene-9,10-dione carboxamides by coupling a weakly reactive amine, 1-aminoanthracene-9,10-dione, and sterically hindered carboxylic acids was achieved using COMU as the coupling agent. Furthermore, making use of the advantages associated with the super-critical fluid chromatography (SFC) technique, a simplified and straightforward method for the chiral separation of optically active amide derivatives from the impurities associated with the reaction mixture, in a single step, was demonstrated. The antimicrobial activity of selected 1-aminoanthracene-9,10-dione carboxamides was studied. Advanced NMR and other spectral techniques were used for the thorough characterization of all the compounds. This study provides a general and simplified method for coupling a weak amine with a sterically hindered acid using COMU as a coupling agent, and demonstrates the separation of optically pure compounds from reaction related impurities in a single step using SFC, and identification of amide derivatives of 1-aminoanthracene-9,10-dione as potential antimicrobial agents.

Antitumor copper(II) complexes with hydroxyanthraquinones and N,N-heterocyclic ligands. J Inorg Biochem 2023; 241:112121.

Abstract
Five ternary copper(II) complexes, [Cu2(phen)2(L1)(ClO4)2] (1), [Cu2(phen)2(L1)(DMSO)2](PF6)2 (2), [Cu2(bpy)2(L1)(ClO4)2(H2O)2] (3), [Cu2(dmp)2(L1)(ClO4)2(H2O)2] (4), and [Cu(phen)(L2)]2(ClO4)2 (5), in which phen = 1,10-phenanthroline, bpy = 2,2'-bipyridine, dmp = 2,9-dimethyl-1,10-phenanthroline, H2L1 = 1,4-dihydroxyanthracene-9,10-dione and HL2 = 1-hydroxyanthracene-9,10-dione, DMSO = dimethylsulfoxide, were synthesized and fully characterized. Complex 2 was obtained through the substitution of perchlorate for DMSO. When two hydroxyquinone groups are present, L1 makes a bridge between two Cu(II) ions, which also bind two nitrogens of the respective diimine ligand. The compounds bind to calf thymus DNA and oxidatively cleave pUC19 DNA according to the following order of activity 1 > 4-5 > 3. Furthermore, complexes 1, 3, 4 and 5 inhibit topoisomerase-I activity and the growth of myelogenous leukemia cells with the IC50 values of 1.13, 10.60, 0.078, and 1.84 μmol L-1, respectively. Complexes 1 and 4 are the most active in cancer cells and in DNA cleavage.

Journey of anthraquinones as anticancer agents - a systematic review of recent literature. RSC Adv 2021; 11:35806-35827. [PMID: 35492773 PMCID: PMC9043427 DOI: 10.1039/d1ra05686g] [Citation(s) in RCA: 41] [Impact Index Per Article: 13.7] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Accepted: 10/06/2021] [Indexed: 12/19/2022] Open
Abstract
Anthraquinones are privileged chemical scaffolds that have been used for centuries in various therapeutic applications. The anthraquinone moiety forms the core of various anticancer agents. However, the emergence of drug-resistant cancers warrants the development of new anticancer agents. The research endeavours towards new anthraquinone-based compounds are increasing rapidly in recent years. They are used as a core chemical template to achieve structural modifications, resulting in the development of new anthraquinone-based compounds as promising anticancer agents. Mechanistically, most of the anthraquinone-based compounds inhibit cancer progression by targeting essential cellular proteins. Herein, we review new anthraquinone analogues that have been developed in recent years as anticancer agents. This includes a systematic review of the recent literature (2005-2021) on anthraquinone-based compounds in cell-based models and key target proteins such as kinases, topoisomerases, telomerases, matrix metalloproteinases and G-quadruplexes involved in the viability of cancer cells. In addition to this, the developments in PEG-based delivery of anthraquinones and the toxicity aspects of anthraquinone derivatives are also discussed. The review dispenses a compact background knowledge to understanding anthraquinones for future research on the expansion of anticancer therapeutics.

The phenolics from the roots of Livistona chinensis show antioxidative and obsteoblast differentiation promoting activity. Molecules 2013; 19:263-78. [PMID: 24378966 PMCID: PMC6270904 DOI: 10.3390/molecules19010263] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2013] [Revised: 12/10/2013] [Accepted: 12/13/2013] [Indexed: 02/07/2023] Open
Abstract
This study investigated the antioxidative and obsteoblast differentiation promoting activity of the phenolics isolated from the 70% ethanol extract of the roots of Livistona chinensis. Two new phenolics, (2R,3R)-3,5,6,7,3',4'-hexahydroxyflavane (1), and phenanthrene-2,4,9-triol (2), together with six known phenolics 3-8, were isolated and identified on the basis of extensive spectroscopic analysis. The antioxidative and obsteoblast differentiation promoting abilities of the compounds 1-3, 7-8 were tested, the phenolics 1-3, 7 showed effects on proliferation of osteoblastic cells and antioxidative activity of 3.125-50 µg/mL. In addition, the phenolics 1-3 observably increased alkaline phosphatase activity, osteocalcin content and hydroxyproline content in osteoblastic cells. Phenolic 1 at 12.5 µg/mL concentration significantly increased the area of nodules by about 9.35-fold. The antioxidative activity results indicated that the anti-osteoporosis effects of these phenolics may be linked to a reduction of oxidative stress. The observed effects of these phenolics on bone formation by rat osteoblastic cells suggest that these phenolics may have beneficial effects on bone health.

Abstract
Chromenopyrazolediones have been designed and synthesized as anticancer agents using the multi-biological target concept that involves quinone cytotoxicity and cannabinoid antitumor properties. In cell cytotoxicity assays, these chromenopyrazolediones have antiproliferative activity against human prostate cancer and hepatocellular carcinoma. It has been shown that the most potent, derivative 4 (PM49), inhibits prostate LNCaP cell viability (IC₅₀ = 15 μM) through a mechanism involving oxidative stress, PPARγ receptor and partially CB₁ receptor. It acts on prostate cell growth by causing G₀/G₁ phase arrest and triggering apoptosis as assessed by flow cytometry measurements. In the in vivo treatment, compound 4 at 2 mg/kg, blocks the growth of LNCaP tumors and reduces the growth of PC-3 tumors generated in mice. These studies suggest that 4 is a good potential anticancer agent against hormone-sensitive prostate cancer.

Abstract
Aminoanthraquinones were successfully synthesized via two reaction steps. 1,4-Dihydroxyanthraquinone (1) was first subjected to methylation, reduction and acylation to give an excellent yield of anthracene-1,4-dione (3), 1,4-dimethoxyanthracene-9,10-dione (5) and 9,10-dioxo-9,10-dihydroanthracene-1,4-diyl diacetate (7). Treatment of 1, 3, 5 and 7 with BuNH2 in the presence of PhI(OAc)2 as catalyst produced seven aminoanthraquinone derivatives 1a, b, 3a, and 5a–d. Amination of 3 and 5 afforded three new aminoanthraquinones, namely 2-(butylamino)anthracene-1,4-dione (3a), 2-(butylamino)anthracene-9,10-dione (5a) and 2,3-(dibutylamino)anthracene-9,10-dione (5b). All newly synthesised aminoanthraquinones were examined for their cytotoxic activity against MCF-7 (estrogen receptor positive human breast) and Hep-G2 (human hepatocellular liver carcinoma) cancer cells using MTT assay. Aminoanthraquinones 3a, 5a and 5b exhibited strong cytotoxicity towards both cancer cell lines (IC50 1.1–13.0 µg/mL).
