Novel Modified GLP-1 Derivatives with Prolonged Glucose-Lowering Ability In Vivo

The rapid degradation of native glucagon-like peptide 1 (GLP-1) by dipeptidyl peptidase-IV (DPP-IV) has advanced new approaches to the generation of degradation-resistant GLP-1 analogs. Chemical coupling of GLP-1 analog to HSA is innovatively achieved by solid-phase peptide synthesis in this study and shows prolonged glucose-lowering ability in vivo. GLP-1(7-37)(Ala8Aib)-Cys-HSA was constructed by solid-phase peptide synthesis through two levels of modification: mutation of Ala8 to aminoisobutyric acid (Aib) to decrease DPP-IV degradation, and conjugation to large serum protein HSA by chemical modification to decrease renal filtration. Glucose tolerance test and insulin secretion assay were performed to examine the biological activity of GLP-1(7-37)(Ala8Aib)-Cys-HSA in vivo in the present research. Long-lasting glucose-lowering and insulin-releasing effects were evaluated up to 4 weeks in T2DM rats. GLP-1(7-37)(Ala8Aib)-Cys-HSA lowered blood glucose in normal mice and T2DM rats. Twice administration of GLP-1(7-37)(Ala8Aib)-Cys-HSA to T2DM rats daily significantly reduced glycemic excursion following IP glucose challenge (P < 0.01 to 0.05) and greatly increased insulin secretion during the 4-week study period. These findings demonstrate that the albumin-conjugated GLP-1 analog mimics the function of native GLP-1 with prolonged activity. Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.

A comparative study of warheads for design of cysteine protease inhibitors

The effects on potency of cruzain inhibition of replacing a nitrile group with alternative warheads were explored. The oxime was almost an order of magnitude more potent than the corresponding nitrile and has the potential to provide access to the prime side of the catalytic site. Dipeptide aldehydes and azadipeptide nitriles were found to be two orders of magnitude more potent cruzain inhibitors than the corresponding dipeptide nitriles although potency differences were modulated by substitution at P1 and P3. Replacement of the alpha methylene of a dipeptide aldehyde with cyclopropane led to a loss of potency of almost three orders of magnitude. The vinyl esters and amides that were characterized as reversible inhibitors were less potent than the corresponding nitrile by between one and two orders of magnitude. (C) 2017 Elsevier Ltd.

Highly chemoselective and efficient production of 2,6-difluorobenzamide using Rhodococcus ruber CGMCC3090 resting cells

Chemoselective biocatalytic hydrolysis of nitriles is a valuable alternative to chemical hydrolysis that operates under harsh conditions. 2,6-Difluorobenzamide (DFBAM) is an essential intermediate derived from synthesis of benzoyl urea insecticide from 2,6-difluorobenzonitrile (DFBN). High yield of DFBAM was achieved, and the method using resting cells of Rhodococcus ruber CGMCC3090 exhibited excellent product specificity. The reaction parameters for DFBAM biosynthesis were also investigated. The resting cells effectively converted DFBN at high concentrations of up to 3.5 mol L-1 without forming acids or other by-products. Therefore, biological production of DFBAM features high yield, chemoselectivity, low cost, and environment friendliness and is more suitable to the industry than chemical synthesis techniques.

Direct Vicinal Difunctionalization of Thiophenes Enabled by the Palladium/Norbornene Cooperative Catalysis

Herein we report a direct vicinal difunctionalization of thiophenes via the palladium/norbornene (Pd/NBE) cooperative catalysis. A series of mono- and disubstituted thiophenes can be difunctionalized site-selectively and regioselectively at the C4 and CS positions in good yields, enabled by an arsine ligand and a unique amide-based NBE. The synthetic utility has been shown in derivatizations of complex bioactive compounds and an open-flask gram-scale preparation. Preliminary results have been obtained in the difunctionalization of furans and a direct C4-selective arylation of 2-substituted thiophenes.

A time-course investigation of resistance to the carboxylic acid amide mandipropamid in field populations of Plasmopara viticola treated with anti-resistance strategies

BACKGROUND Despite anti-resistance strategies being recommended to reduce selection pressure on insensitive strains, no information is available on fungal population dynamics following their application in real field conditions. In this study, the effects on Plasmopara viticola populations of two identical spray programs, differing only in including or not the carboxylic acid amide (CAA) mandipropamid in mixture and in alternation with an anti-resistance partner, were compared in terms of downy mildew control efficacy and mandipropamid sensitivity in two commercial vineyards for four seasons. RESULTS CONCLUSION Both programs effectively and similarly protected grapevine from downy mildew, despite different starting sensitivity levels of the P. viticola populations. In the vineyard where resistant strains were initially present, the frequency of mutations associated with resistance (G1105S/V) fluctuated within seasons in both programs and a shift towards sensitivity occurred after 3 years of the mandipropamid-free program. Where sensitivity was initially present, no changes occurred in the mandipropamid-free program and resistant strains were selected in the mandipropamid program in high disease pressure conditions. The anti-resistance strategy including mandipropamid in mixture showed a good field performance, but did not completely prevent an increase in the frequency of insensitive strains. This supports the need for appropriate planning to determine which mixtures should be used in the field. (c) 2018 Society of Chemical Industry

Green synthesis, in vivo and in vitro pharmacological studies of Tamarindus indica based gold nanoparticles

The current investigation aims to synthesize gold nanoparticles (AuNPs) from aqueous extract of Tamarindus indica and to evaluate the in vitro anti-bacterial and in vivo sedative and anelgescic activities of crude extract as well as synthesized AuNPs. Several methods have been reported to synthesize AuNPs; however, most of them were not ecofriendly. In the present study, the green synthesis of AuNPs has been carried out. Using the green synthesis method, AuNPs of T. indica were synthesized at room temperature (25 degrees C) by mixing 5 mL of HAuCl4 (1 mM) with 1 mL of T. indica seed extract solution. This extract solution was prepared by taking 5 gm dry seeds in 100 mL of double deionized water with continuous stirring for up to 24 h at 80 degrees C. The stability of AuNPs was confirmed with the help of relevant experimental techniques including ultraviolet-visible (UV/Vis) showing maximum absorbance at 535-540 nm, Fourier transform infrared showing a broad signal at 3464 cm(-1) which can be attributed to either amide or hydroxyl functionalities and atomic force microscopy analysis showed that the biomaterial surrounding AuNPs was agglomerated which proves the formation of discrete nanostructutres. These AuNPs have been evaluated for their antibacterial potential. The results revealed good antibacterial activity of the samples against. Klebsiella pneumonia, Bacillus subtilis and Staphylococcus epidermidis with 10-12 mm zone of inhibition range. The AuNPs were also found stable at high temperature, over a range of pH and in 1 mM salt solution. Moreover, the crude extract and respective AuNPs also exhibited interesting sedative and analgesic activities. Hence, we focused on phytochemicals-mediated synthesis of AuNPs considered as greatest attention in the treatment of anti-bacterial, analgesic, and sedative.

Variously substituted 2-oxopyridine derivatives: Extending the structure-activity relationships for allosteric modulation of the cannabinoid CB2 receptor

We previously reported the 2-oxopyridine-3-carboxamide derivative EC21a as the first small synthetic CB2R positive allosteric modulator which displayed antinociceptive activity in vivo in an experimental mouse model of neuropathic pain. Herein, we extended the structure-activity relationships of EC21a through structural modifications regarding the p-fluoro benzyl moiety at position 1 and the amide group in position 3 of the central core. The characterization in vitro was assessed through radioligand binding experiments and functional assays (GTP gamma S, cAMP, beta arrestin2). Among the new compounds, the derivatives Al (SV-10a) and A5 (SB-13a) characterized respectively by fluorine atom or by chlorine atom in ortho position of the benzylic group at position 1 and by a cycloheptane-carboxamide at position 3 of the central core, showed positive allosteric behavior on CB2R. They enhanced the efficacy of CP55,940 in [S-35]GTP gamma S assay, and modulated CP55,940-dependent beta arrestin2 recruitment and cAMP inhibition. The obtained results extend our knowledge of the structural requirements for interaction with the allosteric site of CB2R. (C) 2020 Elsevier Masson SAS. All rights reserved.

Reusable Fe2O3-nanoparticle catalysed efficient and selective hydroboration of carbonyl compounds

The first Fe2O3-nanoparticle catalysed hydroboration of aromatic and aliphatic aldehydes and ketones with HBpin (pin = OCMe2CMe2O) is reported. The reaction proceeds under mild conditions (room temperature) and is moderately sensitive to air. This process is applicable to a broad range of substrates with high functional group compatibility. Moreover, aldehydes are selectively hydroborated over other reducible functional groups, such as ketone, nitrile, hydroxide, alkene, amide, ester, nitro and halide groups.

Prolinamides of Aminouracils, Organocatalyst Modifiable by Complementary Modules

We report the synthesis and evaluation of prolinamide organocatalysts that incorporate aminouracils. The features of these catalysts are enhanced NH acidity of the amide because of the electron-withdrawing nature of the heterocycle, an additional hydrogen-bond donor at the alpha or beta positions of this functional group (using 6-aminouracil or 5,6-diaminouracil respectively), and it can be recovered due to its low solubility and used again without decreasing the enantioselectivity. A unique feature of these systems is the self-assembly capability with complementary modules by Watson-Crick interactions. These supramolecular adducts behave differently from the catalyst alone, some of them have lower performance but others improve the selectivity of the product. Therefore, this approach avoids the synthesis of many catalysts.
