摘要：
Chronic infection is considered a risk factor for atherosclerosis. The link between infectious agents and atherosclerosis is manifested by the presence of infection-induced pyroptotic cells in atherosclerotic lesions. Pyroptosis is an inflammatory form of programmed cell death that occurs most frequently upon infection. However, inflammation is not the only cause by which pyroptosis involved in atherosclerosis. During pyroptosis, a large amount of microparticles are released from pyroptotic cells, which not only transfer inflammatory mediators to arterial vessel, but also mediate the interaction between a variety of cells, leading to endothelial injury, macrophage infiltration, vascular smooth muscle cell migration and proliferation, thereby accelerating atherosclerosis. Thus, we proposed hypothesis that pyroptotic cell-derived microparticle is an atherogenic factor in infectious diseases.

摘要：
Triple-negative breast cancer (TNBC) is insensitive to endocrine therapies and targeted therapies to human epidermal growth factor receptor-2 (HER2), estrogen receptor (ER) and progesterone receptor (PR). New targets and new targeted therapeutic drugs for TNBC are desperately needed. Our study confirmed that DCC-2036 inhibited the proliferation, invasion, migration and epithelial-mesenchymal transition (EMT) of TNBC cells as well as induced apoptosis. Moreover, the antiproliferative activity of DCC-2036 was more efficient than that of most clinical drugs. In addition, the combination of DCC-2036 and cisplatin or lapatinib had synergistic effects on TNBC cells. Mechanistically, DCC-2036 targeted AXL/MET, especially AXL, and regulated the downstream PI3K/Akt-NFkappaB signaling to exert its antitumor effect in TNBC. DCC-2036 also inhibited the growth and metastasis of xenografted MDA-MB-231 cells (AXL/MET-high TNBC cells) but not MDA-MB-468 cells (AXL-low TNBC cells) in NSG mice in vivo. Furthermore, DCC-2036 significantly inhibited tumor growth and invasion of AXL/MET-high TNBC PDX tumors but not AXL/MET-low TNBC PDX tumors. These results highlighted the roles of AXL/MET in cancer growth and metastasis and further verified that the critical targets of DCC-2036 are AXL and MET, especially AXL. In addition, there was no significant toxicity of DCC-2036 even at a high dosage. Therefore, DCC-2036 may be a potential compound to treat TNBC, especially for tumors with AXL/MET overexpression.

摘要：
Macrophage colony-stimulating factor (M-CSF), a tumour marker, is related to tumour cell anti-apoptosis and drug resistance. However, the role of M-CSF in MCF-7 cells is unknown. In the present study, the effect and mechanism of M-CSF on hypoxia-inducible factor-1 (HIF-1)/BCL2/adenovirus E1B 19 kDa-interacting protein 3 (BNIP3)/Apoptosis Regulator BAX signalling in human breast cancer MCF-7 cells were investigated. Western blotting revealed that the expression of HIF-1, BNIP3, Bax, caspase-3 and caspase-9 was lower in MCF-7-M cells compared to MCF-7 and MCF-7-C cells treated with adriamycin (ADM). Immunoprecipitation combined with western blotting was used to detect the interaction between Bcl-2 and BNIP3 or Bax protein. MCF-7-M cells had a higher amount of Bax binding to Bcl-2 compared to MCF-7 cells or MCF-7-C cells, while the amount of BNIP3 binding to Bcl-2 was decreased in MCF-7-M cells. Hoechst 33342 staining and flow cytometry were utilized to evaluate the effect of M-CSF on apoptosis in MCF-7 cells treated with ADM. Compared to ADM-treated MCF-7 cells, the apoptotic rate of MCF-7-M cells was significantly decreased. These effects were dependent on the concentration of ADM. In conclusion, cytoplasmic M-CSF suppressed apoptosis by inhibiting the HIF-1/BNIP3/Bax signalling pathway, which potentiated the dissociation of Bcl-2 from Bcl-2-BNIP3 compounds and the formation of Bcl-2-Bax compounds.

摘要：
A series of tryptamine salicylic acid derivatives were synthesized and their antiproliferative activity against MGC-803, MCF-7, HepG2, A549 and HeLa cell lines was evaluated. The structure-activity relationship (SAR) study revealed that different substitutions of the C5 and C3'-C5' positions have certain effects on the anti-proliferation activity. The growth assay revealed that N-[2-(5-bromo-1H-indol-3-yl)-ethyl]-2-hydroxy-3-methyl-benzamide (E20) showed the most potent and broad-spectrum anticancer inhibition of all the cell lines evaluated, and was only more potent than 5-Fu for the gastric cancer cell line. Preliminary studies indicated that compound E20 could inhibit colony formation and migration of MGC-803 cells. The flow cytometry (FCM) results showed that compound E20 arrested the cell cycle in the G2/M phase and induced apoptosis of MGC-803 cells in a concentration-dependent manner. In addition, the western blot results showed that E20 can down-regulate the expression of hexokinase 2. Our studies suggest that the framework of N-[2-(5-bromo-1H-indol-3-yl)-ethyl]-2-hydroxy-3-methyl-benzamide may be consider as a new type of chemical for designing effective anti-cancer drugs targeting gastric cancer cells.

摘要：
According to the pharmacophore combination principle, a set of new 3,4,5-trimethoxy flavonoid salicylate derivatives were designed, synthesized, and evaluated for biological activity. The cytotoxicity evaluation revealed that compound 10v exhibited higher potency than 5-Fu against HCT-116 cells. Preliminary biological activity studies showed that compound 10v could inhibit the colony formation and migration of HCT-116 cells. Besides, the Hoechst 33258 staining assay and flow cytometry revealed that treatment with compound 10v induced the apoptosis of HCT-116 cells in a concentration-dependent manner, while it had no effect on their cell cycle. The WB analysis suggested that HIF-1, tubulin, HK-2, and PFK might be the potential pharmacophore targets of compound 10v. Tubulin was a potential drug target for compound 10v, which was explained by analyzing the crystal structure of compound 10v complexed with tubulin. These results indicated that compound 10v might be a promising anti-tumor agent candidate, deserving further optimization and evaluation.
摘要：
A series of chrysin salicylate derivatives as potential antitumour agents were synthesised and evaluated their antitumour activities in vitro and in vivo. Most of the compounds exhibited moderate to good activities against MCF-7 cells, HepG2 cells, MGC-803cells and MFC cells. Among them, compound 3f showed the most potent activity against MGC-803 cells and MFC cells with IC50 values of 23.83 ± 3.68 and 27.34 ± 5.21 μM, respectively. The flow cytometry assay reconfirmed that compound 3f promoted the occurrence of tumour cells’ G1/S block under the inhibiting effect of compound 3f. Compound 3f possessed higher antitumour efficacy in tumour-bearing mice, compared with the positive control 5-Fu and the blank control saline.

摘要：
A series of chrysin benzimidazole derivatives were synthesised and evaluated for their anticancer activity in the search for potential anticancer agents. Among them, compound 18 displayed the most potent anti-proliferative activity against MFC cells with IC50 values of 25.72 ± 3.95 μM. The flow cytometry results displayed that compound 18 induced apoptosis of MFC cells in a dose-dependent manner and caused the cell cycle to be arrested in the G0/G1 phase. Furthermore, the preliminary anticancer activity in vivo was also studied in tumour-bearing mice, and the compound 18 exerted good inhibition effect on tumour growth. These results suggested that compound 18 had good anticancer activity, which could be a potential anticancer agent after further optimisation and evaluation.
