Pektas, Bercis;Sagdic, Gokhan;Daglar, Ozgun;Luleburgaz, Serter;Gunay, Ufuk Saim;Hizal, Gurkan;Tunca, Umit;Durmaz, Hakan research published 《 Ultrafast synthesis of dialkyne-functionalized polythioether and post-polymerization modification via click chemistry》, the research content is summarized as follows. Herein, we prepare a polythioether with double “clickable” alkyne groups in each repeating unit via an extremely rapid polymerization method and combine it with Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) “click” reaction to construct new topol. polymers. A monomer having both electron-deficient and electron-rich dual alkyne functionalities was synthesized and subsequently reacted with 1,6-hexanedithiol (HDT) using 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) as a catalyst, and the reaction proceeded at room temperature for 1 min to give polythioether P1. The obtained polymer was then used as a polymer platform and reacted with a variety of azide compounds to modify the pendant alkynes via CuAAC reaction. The post-polymerization modification (PPM) studies have also been shown to be rapid as the reactions reached completion in 1 h. All synthesized polymers were analyzed using various spectroscopic methods and the results confirmed that quant. “click” reaction efficiency was achieved in each reaction. It is believed the presented strategy not only provides a time-saving approach for both polymer synthesis and PPM, but also brings a new insight to impart the desired functionalities to a polymer chain with CuAAC “click” chem. Thus, a new type of polymer structure that can be prepared rapidly and undergoes fast PPM has been introduced to polymer chem. with this study.

Water transport rate in network membranes is inversely correlated to thickness, thus superior permeance is achievable with ultrathin membranes prepared by complicated methods circumventing nanofilm weakness and defects. Conferring ultrahigh permeance to easily prepared thicker membranes remains challenging. Here, a tetrakis(hydroxymethyl) phosphonium chloride (THPC) monomer is discovered that enables straightforward modification of polyamide composite membranes. Water permeance of the modified membrane is ≈6 times improved, give rising to permeability (permeance x thickness) one magnitude higher than state-of-the-art polymer nanofiltration membranes. Meanwhile, the membrane exhibits good rejection (RNa₂SO₄ = 98%) and antibacterial properties under crossflow conditions. THPC modification not only improves membrane hydrophilicity, but also creates addnl. angstrom-scale channels in polyamide membranes for unimpeded transport of water. This unique mechanism provides a paradigm shift in facile preparation of ultrapermeable membranes with unreduced thickness for clean water and desalination.

The identification and removal of all gross and microscopic tumor to render the patient disease free represents a huge challenge in ovarian cancer treatment. The presence of residual disease is an independent neg. prognostic factor. Herein, we describe the synthesis and the “in vitro” evaluation of compounds as cyclooxygenase (COX)-1 inhibitors, the COX-1 isoform being an ovarian cancer biomarker, each bearing fluorochromes with different fluorescence features. Two of these compounds N-[4-(9-dimethylimino-9H-benzo[a]phenoxazin-5-ylamino) butyl]-2-(3,4-bis(4-methoxyphenyl)isoxazol-5-yl)acetamide chloride (RR11) and 3-(6-(4-(2-(3,4-bis(4-methoxyphenyl)isoxazole-5-yl)acetamido)butyl)amino-6-oxohexyl)-2-[7-(1,3-dihydro-1,1-dimethyl-3-Et 2H-benz[e]indolin-2-yl-idene)-1,3,5-heptatrienyl]-1,1-dimethyl-3-(6-carboxilato-hexyl)-1H-benz[e]indolium chloride, 23 (MSA14) were found to be potent and selective inhibitors of cyclooxygenase (COX)-1 “in vitro”, and thus were further investigated “in vivo”. The IC₅₀ values were 0.032 and 0.087 μM for RR11 and 23 (MSA 14), resp., whereas the COX-2 IC₅₀ for RR11 is 2.4 μM while 23 (MSA14) did not inhibit COX-2 even at a 50 μM concentration Together, this represented selectivity index = 75 and 874, resp. Structure-based virtual screening (SBVS) performed with the Fingerprints for Ligands and Proteins (FLAP) software allowed both to differentiate highly active compounds from less active and inactive structures and to define their interactions inside the substrate-binding cavity of hCOX1. Fluorescent probes RR11 and 23 (MSA14), were used for preliminary near-IR (NIR) fluorescent imaging (FLI) in human ovarian cancer (OVCAR-3 and SKOV-3) xenograft models. Surprisingly, a tumor-specific signal was observed for both tested fluorescent probes, even though this signal is not linked to the presence of COX-1.

Peter Ventura, Alejandra M.;Haeberlein, Simone;Konopka, Leonie;Obermann, Wiebke;Gruenweller, Arnold;Grevelding, Christoph G.;Schlitzer, Martin research published 《 Synthesis and antischistosomal activity of linker- and thiophene-modified biaryl alkyl carboxylic acid derivatives》, the research content is summarized as follows. Schistosomiasis is a neglected tropical disease caused by blood flukes of the genus Schistosoma and causes severe morbidity in infected patients. In 2018, 290.8 million people required treatment, and 200,000 deaths are reported per yr. Treatment of this disease depends on a single drug, praziquantel (PZQ). However, in the past few years, reduced sensitivity of the parasites toward PZQ has been reported. Therefore, there is an urgent need for new drugs against this disease. In the past few years, we have focused on a new substance class called biaryl alkyl carboxylic acid derivatives, which showed promising antischistosomal activity in vitro. Structure-activity relationship (SAR) studies of the carboxylic acid moiety led to three promising carboxylic amides (morpholine, thiomorpholine, and Me sulfonyl piperazine) with an antischistosomal activity down to 10μM (morpholine derivative) and no cytotoxicity up to 100μM. Here, we show our continued work on this substance class. We investigated, in extended SAR studies, whether modification of the linker and the thiophene ring could improve the antischistosomal activity. We found that the exchange of the alkyl linker by a pentadienyl or benzyl linker was tolerated and led to similar antischistosomal effects, whereas the exchange of the thiophene ring was not tolerated. Our data suggest that the thiophene ring is important for the antischistosomal activity of this compound class.

Peterson, Gregory I.;Noh, Jinkyung;Ha, Min Young;Yang, Sanghee;Lee, Won Bo;Choi, Tae-Lim research published 《 Influence of Grafting Density on Ultrasound-Induced Backbone and Arm Scission of Graft Copolymers》, the research content is summarized as follows. The influence of grafting d. on polymer conformations and ultrasonic degradation of polynorbornene-g-polystyrene (PS) or poly(Me acrylate) (PMA) graft copolymers was explored. Multi-angle light scattering anal., at. force microscopy imaging, and mol. dynamics simulations supported that graft copolymers exhibited increased backbone and arm extension and increased arm-arm interactions at higher grafting d. In regard to backbone scission, faster scission rates were observed at higher grafting d., which was further supported by the generation of master curves that account for the rate enhancement due to the polymer being in an extended conformation. The grafting d. also influenced arm scission rates, with PS and PMA arms exhibiting opposite trends. Specifically, arm scission was faster for PS at higher grafting d. and faster for PMA at lower grafting d., which was attributed to differences in arm extension and arm-arm interactions between the two arm types.
