Hu, Jiyong;Chao, Tingting;Yuan, Bangpeng;Guo, Yan;Zhang, Junshuai;Zhao, Jin′an;Zhao, Xuemin;Hou, Hongwei research published 《 Benzimidazole-quinoline-based copper complexes: Exploration for their possible antitumor mechanism》, the research content is summarized as follows. In this study, we synthesized and characterised two benzimidazole-quinoline-based copper complexes, namely, [Cu(btmbq)Br]2 (1) and [Cu(btmbq)Cl]2 (2), (btmbq = 3-(1-(1H-benzotriazol-1-y-l)methyl)-6-bromo-1H-benzoimidazol-2-yl)isoquinoline). Both complexes showed strong antitumor abilities against the colon cancer cell line (HCT116) and low cytotoxicity against the normal liver cell line (L-02). The DNA binding affinity was evaluated using CD and fluorescence spectroscopy, and the Ksv and Kapp values were further quantified, revealing that the complexes bound to DNA in the intercalation mode, and caused oxidative damage to pBR322 DNA. Furthermore, complex 1 interfered with the steady-state balance of redox and Ca2+ in HCT116 cells, as well as induced cell mitochondrial membrane potential (Δψm) collapse, ATP dissipation, ultimately arrested the cell cycle in G2 phase and induced cell apoptosis. Further exploration demonstrated that the production of reactive oxygen species (ROS) might be the major contributors to the apoptotic death of HCT116 cells.

Hu, Lijun;Ren, Qiang;Deng, Liming;Zhou, Zongtao;Cai, Zongyu;Wang, Bin;Li, Zheng research published 《 Design, synthesis, and biological studies of novel 3-benzamidobenzoic acid derivatives as farnesoid X receptor partial agonist》, the research content is summarized as follows. Farnesoid X receptor (FXR), a bile acid-activated nuclear receptor, regulates the metabolism of bile acid and lipids as well as maintains the stability of internal environment. FXR was considered as a therapeutic target of liver disorders, such as drug-induced liver injury, fatty liver and cholestasis. The previous reported FXR partial agonist I was a suitable lead compound in terms of its high potent and low mol. size, while the docking study of compound I suggested a large unoccupied hydrophobic pocket, which might be provided more possibility of structure-activity relationship (SAR) study. In this study, we have performed comprehensive SAR and mol. modeling studies based on lead compound I. All of these efforts resulted in the identification of a novel series of FXR partial agonists. In this series, compound II revealed the best activity and strong interaction with binding pocket of FXR. Moreover, compound II protected mice against acetaminophen-induced hepatotoxicity by the regulation of FXR-related gene expression and improving antioxidant capacity. In summary, these results suggest that compound II is a promising FXR partial agonist suitable for further investigation.

Hu, Pan;Shen, Shaohang;Zhao, Donghua;Wei, Hua;Ge, Jun;Jia, Feiyue;Zhang, Xiangxiang;Yang, Hu research published 《 The influence of hydrophobicity on sludge dewatering associated with cationic starch-based flocculants》, the research content is summarized as follows. Coagulation/flocculation is an extensive and effective pretreatment technol. for improving the sludge dewaterability. A series of hydrophobically associated cationic starch-based flocculants (CS-DMRs) with different degrees of hydrophobicity but similar charge densities were designed and synthesized. The CS-DMRs exhibited excellent sludge dewatering performance. The dewaterability of sludge increased with the hydrophobicity of the CS-DMRs, and the filter cake moisture content (FCMC) and specific resistance to filtration (SRF) could be reduced from 95.47% and 7.09 x 10¹² m/kg to 79.26% and 2.258 x 10¹² m/kg, resp., at a constant pressure of 0.05 MPa after conditioned by the starch-based flocculant with the highest hydrophobicity at its optimal dose. Moreover, due to their amphiphilic structures, CS-DMRs could closely interact with the neg. charged extracellular polymeric substances (EPS), efficiently compress the protein and polysaccharide in EPS, and release the bound water. A second-order polynomial model was proposed according to the phenomenol. theory to quant. analyze the effect of hydrophobicity in these starch-based flocculants on the sludge dewaterability. The structure-activity relationship was built, and the optimal dose and corresponding FCMC could be theor. estimated accordingly. The results were in good agreement with the exptl. results. The dewatering mechanisms were also discussed in detail on the basis of the changes in the FCMC, SRF, capillary suction time, properties of sludge flocs, compression coefficient, microstructures of sludge cakes, EPS fractions and components, and spatial distributions of the proteins and polysaccharides. In addition to charge neutralization, the hydrophobic association effects of CS-DMRs played an important role in the formation of drainage channels and net-like porous structures in the sludge cake to improve its permeability and filterability. This study thus provided a good understanding of the structural effects of the starch-based flocculants on the sludge dewaterability. The results are greatly beneficial to the fabrication and utilization of environment-friendly and high-performance natural polymeric conditioners for sludge treatment.

Hu, Qiang;Wang, Kesi;Qiu, Liyan research published 《 The 6-Aminocaproic acid as a linker to improve near-infrared fluorescence imaging and photothermal cancer therapy of PEGylated indocyanine green》, the research content is summarized as follows. Clin. extensive application of indocyanine green (ICG) is limited by several drawbacks such as poor bioenvironmental stability, aggregate propensity, and rapid elimination from the body, etc. In this study, we construct a novel amphiphilic mPEG-ACA-ICG conjugate by modifying synthetic heptamethine cyanine derivative ICG-COOH with a hydrophobic linker 6-aminocaproic acid (ACA) and amino-terminal poly(ethylene glycol) (mPEG-NH2). The as-prepared mPEG-ACA-ICG conjugate has the ability to self-assemble into micellar aggregates in an aqueous solution with a lower CMC value than mPEG-ICG conjugate without ACA linker. More importantly, compared with free ICG and mPEG-ICG conjugate, mPEG-ACA-ICG nanomicelles exhibited better stability and higher photothermal conversion efficiency upon near-IR light irradiation due to the intramol. introduction of a hydrophobic ACA segment. In our in vivo experiment, mPEG-ACA-ICG nanomicelles ensured the formidable effect on tumor photothermal therapy (PTT) and the maximum tumor inhibition rate reached 72.6%. In addition, real-time determination ability for fluorescence image-guided surgery (FIGS) of mPEG-ACA-ICG nanomicelles was also confirmed on tumor xenograft mice model. Taken together, mPEG-ACA-ICG conjugate may hold great promise for non-invasive cancer theranostics.

Hu, Rong;Wang, Wan-Li;Yang, Ying-Yue;Hu, Xia-Tong;Wang, Qi-Wei;Zuo, Wei-Qiong;Xu, Ying;Feng, Qiang;Wang, Ning-Yu research published 《 Identification of a selective BRD4 PROTAC with potent antiproliferative effects in AR-positive prostate cancer based on a dual BET/PLK1 inhibitor》, the research content is summarized as follows. BRD4-targeted proteolysis targeting chimera (PROTAC) have exhibited promising in vitro and in vivo anticancer activity in a number of cancer models. However, the clin. development of current reported BRD4-PROTACs have stagnated, largely due to the safety risks caused by their poor degradation selectivity. In this study, we designed and synthesized a series of PROTACs based on our recently reported dual BET/PLK1 inhibitor WNY0824, which led to the discovery of an isoform-selective and potent BRD4-PROTAC 12a (WWL0245).

It could also efficiently induce ubiquitin-proteasomal degradation of BRD4 in AR-pos. prostate cancer cell lines, with sub-nanomolar half-maximal degrading concentration (DC50) and maximum degradation (Dmax) > 99%. Moreover, WWL0245 induced cell cycle arrest at the G0/G1 phase and apoptosis in AR-pos. prostate cancer by downregulation of the protein levels of AR, PSA and c-Myc as well as transcriptionally suppressed AR-regulated genes. WWL0245 was thus expected to be developed as a promising drug candidate for AR-pos. prostate cancer and a valuable tool compound to study the biol. function of BRD4.

Hollmann, Tim;Berkhan, Gesche;Wagner, Lisa;Sung, Kwang Hoon;Kolb, Simon;Geise, Hendrik;Hahn, Frank research published 《 Biocatalysts from biosynthetic pathways: Enabling stereoselective, enzymatic cycloether formation on a gram scale》, the research content is summarized as follows. Biosynthetic pathways of natural products contain many enzymes that contribute to the rapid assembly of mol. complexity. Enzymes that form complex structural elements with multiple stereocenters, like chiral saturated oxygen heterocycles (CSOH), are of particular interest for a synthetic application, as their use promises to significantly simplify access to these elements. Here, the biocatalytic characterization of AmbDH3, an enzyme that catalyzes intramol. oxa-Michael addition (IMOMA) is reported. This reaction essentially gives access to various types of CSOH with adjacent stereocenters, but it is not yet part of the repertoire of preparative biocatalysis. An in-depth study on the synthetic utility of AmbDH3 was performed, which made extensive use of complex synthetic precursor surrogates. The enzyme exhibited stability and broad substrate tolerance in in vitro experiments, which was in agreement with the results of mol. modeling. Its selectivity profile enabled kinetic resolution of chiral tetrahydropyrans (THPs) under control of up to four stereocenters. A systematic optimization of the reaction conditions enabled gram-scale conversions yielding preparative amounts of chiral THP. The synthetic utility of AmbDH3 was finally demonstrated by its successful application in the key step of a chemoenzymic total synthesis to the THP-containing phenylheptanoid (-)-centrolobine. These results highlight the synthetic potential of AmbDH3 and related IMOMA cyclases as a biocatalytic alternative that further develops the available chem.-synthetic IMOMA methodol.

The thermal behavior, including the cold crystallization, of alkyl-derivatized Sudan III (1-[4-(phenylazo)phenylazo]-2-naphthol), SD3-OCn, was investigated. Its structural flexibility due to the two azo groups caused the formation of plural crystal structures, which further resulted in complex cold crystallization A metastable nonflat structure and a thermodynamically stable flat structure resulted in the two sets of crystallization and melting behavior during the heating process. Further, the change in the alkyl chain length caused variations in the crystallization rate and crystallinity, thus systematically changing the cold crystallization behavior. It was proven that the high mobility of the Ph group triggered supercooling and cold crystallization and that the alkyl chain correspondingly controlled the thermal behavior.
