Design, synthesis and structure?activity relationship studies of GPR40 agonists containing amide linker

Free fatty acid receptor 1 (FFAR1/GPR40) attracted significant attention as a potential target for developing novel antidiabetic drugs because of its unique mechanism in glucose homeostasis. Several reports have expressed concerns about central nervous system (CNS) penetration of GPR40 agonists, which is possibly attributed to their high lipophilicity and low total polar surface area. Herein, we report our efforts to improve the physicochemical properties and pharmacokinetic profiles of LY2881835, a GPR40 agonist that had undergone Phase I clinical trial, through a series of structural optimizations. We identified an orally efficacious compound, 15k, which possessed increased plasma exposure, prolonged half-life and reduced CNS exposure and liver to plasma distribution ratio compared with LY2881835. 15k is a potentially valuable lead compound in the development of safe and efficacious GPR40-targeted drugs to treat type 2 diabetes mellitus.

Facilely Synthesizing Ethynyl Terminated All-Aromatic Liquid Crystalline Poly(esterimide)s with Good Processability and Thermal Resistance under Medium-Low Temperature via Direct Esterification

Developing a facile strategy to synthesize thermosetting all-aromatic liquid crystalline poly(esterimide)s (LCPEIs) at medium-low temperature and endowing LCPEIs with good processability and high thermal resistance are still two big challenges. Herein, a new solution polymerization based on direct esterification under 120 C is developed, overcoming bottlenecks of traditional melt and solution polymerizations. Besides, two new reactive LCPEIs (LCPEI-1 and LCPEI-2) terminated with 3-ethynylaniline (3-EA) were synthesized, and their structures and properties were compared with two control samples without 3-EA end groups. LCPEI-1 and LCPEI-2 not only show good processing characteristics including low melting temperature (Tm = 200 C), low melting viscosity, and good solubility in solvent, but their cured samples also have high glass transition temperature (Tg = 192 and 225 C) and high storage modulus, whereas control samples, even treated with similar thermal history as curing procedure for LCPEI-1 and LCPEI-2, have poor performances. Cured-LCPEI-2 exhibits the highest Tg among polyesters with low Tm values (<250 C) reported. The mechanism behind outstanding performances of LCPEIs is discussed. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 18959-30-3, help many people in the next few years.Quality Control of 4,5-Difluorophthalic Anhydride

Base-free nickel-catalysed decarbonylative Suzuki?Miyaura coupling of acid fluorides

The Suzuki?Miyaura cross-coupling of organoboron nucleophiles with aryl halide electrophiles is one of the most widely used carbon?carbon bond-forming reactions in organic and medicinal chemistry1,2. A key challenge associated with these transformations is that they generally require the addition of an exogenous base, the role of which is to enable transmetallation between the organoboron nucleophile and the metal catalyst3. This requirement limits the substrate scope of the reaction because the added base promotes competitive decomposition of many organoboron substrates3?5. As such, considerable research has focused on strategies for mitigating base-mediated side reactions6?12. Previous efforts have primarily focused either on designing strategically masked organoboron reagents (to slow base-mediated decomposition)6?8 or on developing highly active palladium precatalysts (to accelerate cross-coupling relative to base-mediated decomposition pathways)10?12. An attractive alternative approach involves identifying combinations of catalyst and electrophile that enable Suzuki?Miyaura-type reactions to proceed without an exogenous base12?14. Here we use this approach to develop a nickel-catalysed coupling of aryl boronic acids with acid fluorides15?17, which are formed in situ from readily available carboxylic acids18?22. This combination of catalyst and electrophile enables a mechanistic manifold in which a ?transmetallation-active? aryl nickel fluoride intermediate is generated directly in the catalytic cycle13,16. As such, this transformation does not require an exogenous base and is applicable to a wide range of base-sensitive boronic acids and biologically active carboxylic acids.

Anhydrides of Arylfuran and Arylpyran Pseudoacids: Formation and Structures; C?O Bond Lengths Trends in Pseudo o-Formylbenzoic Acid Derivatives

Abstract: Three methods for producing anhydrides of arylfuran and arylpyran pseudoacids were explored. These included thermal dehydration, phosgene or thionly chloride activation and decomposition, and dicyclohexylcarbodiimide activation and coupling. Derivatives of the cyclic forms of o-formylbenzoic acid, o-acetylbenzoic acid, 2-carboxyphenylacetaldehyde and of 4,4-dimethyl-3,4-dihydro-3-hydroxy-[1H]-isobenzopyran-1-one were formed including dipseudoanhydides and normal-pseudo anhydrides. Crystal and molecular structures for meso and (R,R/S,S)-bis(1[3H]-isobenzofuranone-3-yl)ether, (R,R/S,S)-bis(3-methyl-1[3H]-isobenzofuranone-3yl)ether, meso (3,4-dihydro-[1H]-isobenzopyran-1-one-3-yl)ether, 3-benzoyloxy-1[3H]-isobenzofuranone, 3-benzoyloxy-3-methyl-1[3H]isobenzofuranone, 3-(4?-nitrobenzoyloxy)-4,4-dimethyl-3,4-dihydro-[1H]-isobenzopyran-1-one, and (1[3H]-isobenzofuranone-3-yl)(4,4,dimethyl-3,4-dihydro-[1H]-isobenzopyran-1-one-3-yl)ether are reported. Endocyclic pseudoacyl C?O bonds are always longer than the exocyclic pseudoacyl C?O bonds. It is possible to refine the previously established C?O bond length dependencies on the pKa (of the conjugate acids) of the leaving groups for 3-substituted 1-[3H]-isobenzofuranones. Of six dipseudoanhydrides studied, conformations are found with exocyclic C?O(ether) linkages synclinal to the endocyclic C?O and away from the ring (exo conformation) in two meso structures, two of three RR/SS forms and in a chiral unsymmetrical form. An endo conformation is observed in one of the RR/SS forms. In three normal-pseudo anhydrides, both endo and exo conformations are observed. Graphic Abstract: Synthetic methods for formation of anhydrides of several arylfuran and arylpyran pseudoacids are described, and the pseudoacyl C?O bond length trends are determined for leaving groups spanning over 30 pKa units.[Figure not available: see fulltext.]

Effect of catalytic vapour cracking on fuel properties and composition of castor seed pyrolytic oil

In this work, catalytic upgrading was carried out to enhance the yield and quality of castor seed pyrolytic oil. The influence of catalytic vapour cracking of castor seed was performed over Kaolin, CaO and ZnO catalysts at various weight percentage of loading. This study confirmed that the yield varied with catalyst type and its amount of loading. The maximum pyrolysis yield of oil was obtained about 66.4 wt.%, 64.9 wt.% and 65.8 wt.% at 15 wt.% CaO and Kaolin and 10 wt.% ZnO respectively. The effect of catalyst on fuel properties were studied at that catalyst loading where the yield of pyrolytic liquid was higher. The fuel properties of castor seed thermal and catalytic pyrolytic oil were compared. The cracking of castor seed pyrolytic vapour over the bed of catalysts proved to enhance the fuel properties of pyrolytic oil for all catalysts. In comparison with ZnO, CaO and Kaolin found to have significant effect on enhancing the fuel properties in terms of viscosity, pH, calorific value and pour point. It was observed that in catalytic pyrolytic oil the number of acidic groups significantly reduced as they got converted to esters compared to thermal pyrolytic oil. The increase in the formation of nitriles and aromatics content in the catalytic pyrolytic oil was also noticed which were comparatively less in the thermal pyrolytic oil.
