1Synthesis and Characterization of Photosensitive Poly(imide sulfonates) for Fuel Cell Application显示文摘The novel sulfonated polyimide membranes were successfully synthesized by thermal imidization with monomers of 4,4'-(hexafluoroisopropylidene)diphthalic anhydride (6FDA), 4,4'-diamino-diphenyl ether-2,2'-disulfonic acid (SODA) and 3,3'-diaminochalcone (3DAC). Photosensitive chalcone moiety was introduced to the main chain of copolymers, and the photocrosslinking of resulting copolymer in aqueous electrolyte was attempted. A series of sulfonated copolyimide precursors containing chalcone functional groups in the main chain were prepared with different sulfonation degrees by controlling the molar ratio of SODA, 6FDA and 3DAC. The polymer membranes were prepared from these sulfonated aromatic precursors by solution casting and subsequent thermal imidization. The crosslinking with UV irradiation was attempted in the presence or absence of distilled water. The characterizations of the resulting membrane such as the ion-exchange capacity, water absorption and ionic conductivity were performed with respect to the copolymer compositions and the photocrosslinking conditions.文璞山 LIU Hui KIM Jae Hoon LI Xiangdan LEE Myong-Hoon 2013Journal of Wuhan University of Technology(Materials Science)2013,28,4:1

3Transformable peptide nanoparticles inhibit the migration of N-cadherin overexpressed cancer cells显示文摘About 90%cancer-related mortality results from the cancer metastasis,which generally undergoes after epithelial-mesenchymal transition(EMT)process.N-Cadherin,overexpressed on cancer cell surface during EMT,can enhance the migration of cancer cells.He rein,we design and synthesize a transformable peptide BP-KLVFF-SWTLYTPSGQSK(BFS)that can block N-cadherin for inhibiting cancer migration and metastasis.The peptide BFS consists of three modules including(1)the hydrophobic bis-pyrene(BP)unit for forming and locating nanoparticles,(2)the KLVFF peptide sequence for forming and stabilizing fibrous structures and(3)the targeting peptide sequence SWTLYTPSGQSK that can specifically bind to Ncadherin.The peptide BFS can form nanoparticles in PBS,which can transform to nanofibers when targeting and binding to N-cadherin.The nanofibers inhibit the migration of N-cadherin overexpressed MDA-MB-436 cancer cells.The peptide BFS shows 83.6%inhibiting rate in cells wound healing assay.In addition,the inhibition rate is 67.9%when the BFS applied in transwell migration assay.These results indicate that the BFS has excellent ability to inhibit migration of cancer cells.This self-assembly strategy could be potentially utilized to regulate the key protein during EMT for inhibiting the tumor metastasis.Jiaqi Fan Yu Fan Zijin Wei Yijing Li Xiangdan Li Lei Wang Hao Wang 2020Chinese Chemical Letters2020,31,7:1
