Discovery of potential anticancer multi-targeted ligustrazine based cyclohexanone and oxime analogs overcoming the cancer multidrug resistance

Zha, Gao-Feng,Qin, Hua-Li,Youssif, Bahaa G.M.,Amjad, Muhammad Wahab,Raja, Maria Abdul Ghafoor,Abdelazeem, Ahmed H.,Bukhari, Syed Nasir Abbas

, p. 34 - 48 (2017)

The drug research and development nowadays is focusing on multi-target drugs. In the treatment of cancer, therapies using drugs inhibiting one numerous targets signify a novel viewpoint. In comparison with traditional therapy, multi-targeted drugs directly aim cell subpopulations which are involved in progression of tumor. The current study comprises the synthesis of 34 novel ligustrazine-containing α, β-unsaturated carbonyl-based compounds and oximes. The growth of 5 various cancer cell types was strongly inhibited by ligustrazine-containing oximes as revealed by biological evaluation. A strong SAR was provided by the antiproliferative activity. The mechanistic effects of most active antiproliferative compounds on tubulin polymerization, EGFR TK kinases, KAF and BRAFV600E were investigated, followed by in?vitro investigation of reversal of efflux-based resistance developed by cancer cells. EGFR was strongly inhibited by two oximes 7e and 8o. Out of all linkers including positive control, 1-isopropyl-piperidin-4-one linker-bearing compounds showed best inhibition of FAK. The strongest inhibitory activity of BRAFV600E was showed by compound 5e with an IC50 of 0.7?μM. Analogs such as 5 and 7 (b,e,f) exhibited a dual role as anticancer as well as MDR reversal agents. For understanding the target protein integrations with new compounds, molecular docking studies were also carried out.

Synthesis and relationship of stability and biological activity of new DSS and TMP conjugates

Sun, Yewei,Tan, Zicheng,Liang, Zhibin,Wang, Liang,Shan, Luchen,Yu, Pei,Lee, Simon Mingyuen,Wang, Yuqiang

, p. 586 - 591 (2015)

A series of novel conjugates of danshensu (DSS) and tetramethylpyrazine (TMP) were designed and synthesized. Their stability toward hydrolysis by carboxylesterase and cardioprotective effect against t-BHP- and doxorubicin-induced damage were evaluated in H9c2 cells. The results revealed that increasing steric hindrance with bulky groups at the linkage position between DSS and TMP prolonged the half-life and also markedly increased the protective effect. Compound 7 was the most potent in protecting against t-BHP- and doxorubicin-induced damage. The protective effect of compound 7 may in part be attributed to its promotion of mitochondrial biogenesis.

Synthesis and biological evaluation of ligustrazine derivatives

Zhang, Chao,Chen, Lang-Di,Liang, Xin-Tong,Liu, Wei-Xiong,Wu, Wen-Hao

, p. 114 - 117 (2017)

Synthesized ligustrazine derivatives (1a, 1b, 1c (novel)) were structurally confirmed by mass spectrometry,1H NMR, and 13C NMR. The cytotoxic activities of all derivatives were evaluated by MTS assay in three human prostate cancer cell lines (PC-3, LNCaP, and DU145) and in the A549 human lung cancer cell line. Compound 1a exhibited strong cytotoxic activity against PC-3 cells (IC50 3.63μM). In addition, compounds 1-1c showed moderate α1-adrenergic receptor (AR) subselective antagonistic and β2-AR agonistic effects, indicating potential use for the treatment of chronic obstructive pulmonary disease. Molecular docking results showed 1b bound to one region of the active site in β2-AR, but 1, 1a, and 1c bound to a different region.

Discovery of a new tetramethylpyrazine based chalcone with α, β-unsaturated ketone moiety as a potential anticancer agent

Bukhari, Syed Nasir Abbas

, p. 826 - 829 (2020/02/25)

In this study, a new ligustrazine-based chalcone molecule has been synthesized that contains an extra α, β-Unsaturated ketone moiety along with α, the β-Unsaturated carbonyl group of chalone. A new tetramethylpyrazine (TMP) based aldehyde was synthesized to make the TMP (ligustrazine) as part of chalcone and then it was reacted with newly synthesized ketone containing additional α, β-Unsaturated ketone moiety. After characterization, this new compound was evaluated for its effect on different types of cancer cell lines and very promising results were obtained. The growth of these cancer cells was inhibited by newly designed and synthesized compounds, especially for colon and pancreatic cancer cells with IC50 0.04-0.05 μM.

Novel Ligustrazine-Based Analogs of Piperlongumine Potently Suppress Proliferation and Metastasis of Colorectal Cancer Cells in Vitro and in Vivo

Zou, Yu,Zhao, Di,Yan, Chang,Ji, Yanpeng,Liu, Jin,Xu, Jinyi,Lai, Yisheng,Tian, Jide,Zhang, Yihua,Huang, Zhangjian

, p. 1821 - 1832 (2018/03/21)

Piperlongumine 1 increases reactive oxygen species (ROS) levels and preferably induces cancer cell apoptosis by triggering different pathways. However, the poor solubility of 1 limits its intensive investigation and clinical application. Ligustrazine possesses a water-soluble pyrazine skeleton and can inhibit proliferation and metastasis of cancer cells. We synthesized compound 3 by replacement of the trimethoxyphenyl of 1 with ligustrazine moiety and further introduced 2-Cl, -Br, and -I to 3 for synthesis of 4-6, respectively. Compound 4 possessed 14-fold greater aqueous solubility than 1 and increased ROS levels in colorectal cancer HCT-116 cells. Additionally, 4 preferably inhibited proliferation, migration, invasion, and heteroadhesion of HCT-116 cells. Treatment with 4 suppressed tumor growth and lung metastasis in vivo and prolonged the survival of tumor-bearing mice. Furthermore, 4 mitigated TGF-β1-induced epithelial-mesenchymal transition and Wnt/β-catenin activation by inhibiting the Akt and GSK-3β phosphorylation in HCT-116 cells. Collectively, 4 displayed significant antiproliferation and antimetastasis activities, superior to 1.
