Schaffner, Arnaud-Pierre;Sansilvestri-Morel, Patricia;Despaux, Nicole;Ruano, Elisabeth;Persigand, Thierry;Rupin, Alain;Mennecier, Philippe;Vallez, Marie-Odile;Raimbaud, Eric;Desos, Patrice;Gloanec, Philippe research published 《 Phosphinanes and Azaphosphinanes as Potent and Selective Inhibitors of Activated Thrombin-Activatable Fibrinolysis Inhibitor (TAFIa)》, the research content is summarized as follows. Selective and potent inhibitors of activated thrombin activatable fibrinolysis inhibitor (TAFIa) have the potential to increase endogenous and therapeutic fibrinolysis and to behave like profibrinolytic agents without the risk of major hemorrhage, since they do not interfere either with platelet activation or with coagulation during blood hemostasis. Therefore, TAFIa inhibitors could be used in at-risk patients for the treatment, prevention, and secondary prevention of stroke, venous thrombosis, and pulmonary embolisms. In this paper, we describe the design, the structure-activity relationship (SAR), and the synthesis of novel, potent, and selective phosphinanes and azaphosphinanes as TAFIa inhibitors. Several highly active azaphosphinanes display attractive properties suitable for further in vivo efficacy studies in thrombosis models.

Sayer, James R.;Wallden, Karin;Koss, Hans;Allan, Helen;Daviter, Tina;Gane, Paul J.;Waksman, Gabriel;Tabor, Alethea B. research published 《 Design, synthesis, and evaluation of peptide-imidazo[1,2-a]pyrazine bioconjugates as potential bivalent inhibitors of the VirB11 ATPase HP0525》, the research content is summarized as follows. Helicobacter pylori (H. pylori) infections were implicated in the development of gastric ulcers and various cancers: however, the success of current therapies is compromised by rising antibiotic resistance. The virulence and pathogenicity of H. pylori is mediated by the type IV secretion system (T4SS), a multiprotein macromol. nanomachine that transfers toxic bacterial factors and plasmid DNA between bacterial cells, thus contributing to the spread of antibiotic resistance. A key component of the T4SS is the VirB11 ATPase HP0525, which is a hexameric protein assembly. The authors have previously reported the design and synthesis of a series of novel 8-amino imidazo[1,2-a]pyrazine derivatives as inhibitors of HP0525. In order to improve their selectivity, and potentially develop these compounds as tools for probing the assembly of the HP0525 hexamer, the authors have explored the design and synthesis of potential bivalent inhibitors. The authors used the structural details of the subunit-subunit interactions within the HP0525 hexamer to design peptide recognition moieties of the subunit interface. Different methods (cross metathesis, click chem., and cysteine-malemide) for bioconjugation to selected 8-amino imidazo[1,2-a]pyrazines were explored, as well as peptides spanning larger or smaller regions of the interface. The IC₅₀ values of the resulting linker-8-amino imidazo[1,2-a]pyrazine derivatives, and the bivalent inhibitors, were related to docking studies with the HP0525 crystal structure and to mol. dynamics simulations of the peptide recognition moieties.

Sayed, Mohammed A.;Saini, Rajesh K.;AlAli, Eyad;Kalgaonkar, Rajendra;Arnous, Ahmed research published 《 Safer Dual-Functional Gas Hydrate Dissolver and Inhibitor to Replace Methanol》, the research content is summarized as follows. In the presence of free water and under certain conditions of temperature and pressure, low-mol.-weight gases such as methane and ethane present in the fluid stream flowing in pipelines cause the formation of gas hydrate crystals. These gas hydrate crystals may accumulate and cause a partial or complete plugging of pipelines in the vertical or horizontal section. Methanol has been used in the industry as an effective gas hydrate dissolver and inhibitor, but its low flashpoint temperature makes it unsafe to be stored and pumped in large volumes The objective of the current work is to develop a safer dissolver and inhibitor for gas hydrate plugs that form in pipelines. Methanol has a very low f.p. (-90°C) and it is completely miscible with water, which can shift the hydrate phase equilibrium to lower temperatures Solvent- and aqueous-based formulations were selected as alternatives to methanol, keeping in mind parameters such as higher flashpoint, miscibility with water, f.p., viscosity, and local availability. The performance of these formulations was evaluated in a see-through gas hydrate reactor. Representative gas and water compositions were used in the experiments to form the gas hydrate inside the reactor. Hydrate formation was detected by the change in torque or by visual inspection through the see-through window of the reactor. Methanol was able to mobilize the hydrate plug when used at 10 vol %, while complete dissolution was achieved at 30 vol %. In comparison, the potassium formate saturated solution achieved complete dissolution of the hydrate plugs at 10 vol % in a lesser time compared to methanol. The tested formulations worked not only as a dissolver but also as an inhibitor to prevent the formation of hydrates once they are melted or dissolved. These formulations enable safer operations in the field and improve the performance when it comes to melting gas hydrate plugs.

Sawicki, Tomasz;Ruszkowska, Monika;Shin, Jessica;Starowicz, Malgorzata research published 《 Free and conjugated phenolic compounds profile and antioxidant activities of honeybee products of polish origin》, the research content is summarized as follows. In this study, the profile of free and conjugated phenolic compounds and antioxidant activity of bee bread, bee pollen, honey and beeswax samples from the same beehive was analyzed. The contents of free phenolic compounds and those released from the esters and glycosides bounds were analyzed by HPLC-TOF-MS/MS method. In the obtained extracts, the total of phenolic (TP) and flavonoid (TF) contents was measured using spectrophotometric methods, while antioxidant activity was determined by DPPH and ABTS in vitro assays. Therefore, in the tested honeybee products 23 phenolic compounds were identified, constituting of 14 phenolic acids and nine flavonoids. Among the phenolic acids, ferulic (bee bread), protocatechuic (bee pollen) and m-coumaric acids (honey and beeswax) were predominant. In case of flavonoids, the major compounds were vitexin in bee bread, orientin in bee pollen, and apigenin in honey. The highest TP and TF contents were detected in the bee pollen, and was 4.11 mg GAE/g and 0.41 mg Q/g, resp. Moreover, these compounds were mostly present in bound form. Honeybee product extracts had high scavenging ability against radicals, and their antioxidant activity differed significantly across samples (p < 0.05). Overall, this study demonstrates that selected honeybee products are an abundant source of the bioactive compounds with the characteristic profile of phenolic compound as well as antioxidant activity.

Saridas, Mehmet Ali;Ag am, Erdal;Akbas, Furkan Cihad;Akyildiz, Asiye;Paydas Kargi, Sevgi research published 《 Comparison of superior bred strawberry genotypes with popular cultivars in terms of fruit bioactive compounds during the wide harvest dates》, the research content is summarized as follows. Secondary compounds of fruit are among the essential concerns due to their pos. effects on human health. Many studies have attempted to improve these compounds by applying different genotype or cultivation practices such as irrigation and fertilization. This study aimed to find out the effect of different harvest dates on strawberry genotypes in terms of total phenolic (TP), total antioxidant activity (TAA), total monomeric anthocyanin (TMA), and some crucial individual phenolic compounds during the five-month growing season (Jan. – May periods) with one month intervals. Besides, superior bred lines (′33′, ′36′ and ′61′) were compared with widely grown cultivars (′Rubygem′, ′Festival′ and ′Fortuna′) under the Mediterranean climate conditions. Regarding the genotypes, it was observed that TMA, TP, TAA, (-) epicatechin, (-) epicatechin gallate, pelargonidin 3- glucoside (P3G), and pelargonidin 3- rutinoside (P3R) values were the highest values in the 33-bred line, while the 36-bred line standed out in terms of ferulic acid and cyanidin 3- glucoside (C3G). This study also has shown that the chlorogenic acid and sinapic acid contents of the 61-bred line were found in the highest level comparing with the others. Regarding the harvest date, fruit antioxidant activity, total phenolic compounds, and individual phenols such as gallic, syringic, ferulic, (-) epicatechin and ellagic acid were measured the highest in May-harvested fruits, whereas these values were observed at the lowest level in March, except for syringic and (-) epicatechin. On the other hand, rutin, quercetin, sinapic acid, chlorogenic and caffeic acids, and P3G and P3R levels of fruits were the highest in Apr., when it was the most intense harvest period in Mediterranean climate conditions. These observations indicated that these compounds could be increased by choosing the right genotype and suitable environmental conditions.

Despite considerable advances in recent years, challenges in delivery and storage of biol. drugs persist and may delay or prohibit their clin. application. Though nanoparticle-based approaches for small mol. drug encapsulation are mature, encapsulation of proteins remains problematic due to destabilization of the protein. Reverse micelles composed of decylmonoacyl glycerol (10MAG) and lauryldimethylamino-N-oxide (LDAO) in low-viscosity alkanes have been shown to preserve the structure and stability of a wide range of biol. macromols. Here, we present a first step on developing this system as a future platform for storage and delivery of biol. drugs by replacing the non-biocompatible alkane solvent with solvents currently used in small mol. delivery systems. Using a novel screening approach, we performed a comprehensive evaluation of the 10MAG/LDAO system using two preparation methods across seven biocompatible solvents with anal. of toxicity and encapsulation efficiency for each solvent. By using an inexpensive hydrophilic small mol. to test a wide range of conditions, we identify optimal solvent properties for further development. We validate the predictions from this screen with preliminary protein encapsulation tests. The insight provided lays the foundation for further development of this system toward long-term room-temperature storage of biologics or toward water-in-oil-in-water biol. delivery systems.
