| 1 | Synergistic Combination of Biodegradable Peptide Polymer and Curcumin as Promising Antibiotic Substitution in Aquaculture to Alleviate the Global Challenge of Antimicrobial Resistance显示文摘The massive use of antibiotics in aquaculture and resulted antibacterial resistance problem urgently need antibiotic substitutions. Herein, we report a promising substitution of aquaculture antibiotics using a synergistic combination of biodegradable peptide polymers and curcumin, a natural compound from plant. The synergistic combination shows strong antibacterial activity against V. fluvialis and some other common bacteria in aquaculture. The membrane-damaging antibacterial mechanism echoes our finding that the synergistic combination will not induce bacteria to develop resistance after continuous use. The synergistic combination also displays effective cure on V. fluvialis-infected zebrafish. The biodegradability of the peptide polymer enables the combination to lose antibacterial activity and will not cause selective pressure on bacterial in the environment. Our study indicates potential application of synergistic composition, biodegradable peptide polymer and curcumin, as promising antibiotic substitution in aquaculture, which represents a promising strategy to address the global challenge of antimicrobial resistance. | Pengcheng Ma Yuan Chen Ning Shao Junyu Zhang Yueming Wu Runhui Liu | 2022 | Chinese Journal of Chemistry2022，40，24： | 1 |
| 2 | Open-vessel Synthesis of Poly-N-methoxyethylglycine显示文摘Polypeptoids are widely used in biological applications owing to their diverse functions and proteolytic stability.One type of polypeptoids,poly-N-methoxyethylglycine(P-Nmeg),has been found to possess remarkable hydrophilicity and notable properties in terms of protein,cell,and bacterial antifouling.However,the currently known synthesis methods of P-Nmeg include solid-phase synthesis,which is time-consuming and difficult to scale up,and N-substituted N-carboxyanhydride(NNCA)ring-opening polymerization,whose monomers were difficult to store.In this study,we used the chemical stable Nmeg N-phenoxycarbonyl(NPC)as the monomer,which was obtained without the use of highly toxic reactants,such as phosgene or phosphorus halide,to synthesize P-Nmeg under open-vessel conditions.By adding BnNH_(2) as an initiator at 80℃,we can obtain controllable short chain length P-Nmeg with narrow dispersity. | LIU Guojan MA Ke CHEN Qi ZHANG Donghui LIU Runhui | 2024 | Chemical Research in Chinese Universities2024，40，1： | 0 |
| 3 | Apigenin, a natural flavonoid, promotes autophagy and ferroptosis in human endometrial carcinoma Ishikawa cells in vitro and in vivo显示文摘Apigenin,a natural flavonoid has been reported against a variety of cancer types.However,it is unclear whether apigenin can promote autophagy and ferroptosis in Ishikawa cells.There are few reports on the mechanism of apigenin on autophagy and ferroptosis of endometrial cancer Ishikawa cells.We found that iron accumulation,lipid peroxidation,glutathione consumption,p62,HMOX1,and ferritin were increased,while,solute carrier family 7 member 11 and glutathione peroxidase 4 were decreased.Ferrostatin-1,an iron-death inhibitor could reverse the effects of apigenin in Ishikawa cells.On the other hand,apigenin could promote autophagy via up-regulating Beclin 1,ULK1,ATG5,ATG13,and LC3B and down-regulating AMPK,mTOR,P70S6K,and ATG4.Furthermore,apigenin could inhibit tumor tissue proliferation and restrict tumor growth via ferroptosis in vivo. | Yancui Liang Qian Zhong Runhui Ma Zhijing Ni Kiran Thakur Jianguo Zhang Zhaojun Wei | 2023 | Food Science and Human Wellness2023，12，6： | 0 |
