Stereoselective Heck-Matsuda arylations of chiral dihydrofurans with arenediazonium tetrafluoroborates; an efficient enantioselective total synthesis of (-)-isoaltholactone

The Heck-Matsuda arylation of chiral 2-(S)-hydroxymethyl dihydrofurans (endocyclic enolethers) and its derivatives, employing arenediazonium tetrafluoroborates, was developed into a highly efficient, practical and diastereoselective synthetic process. This methodology was applied to the total synthesis of the styryllactone (-)-isoaltholactone in seven steps with an overall yield of ?25%, from the readily available chiral 2-hydroxymethyldihydrofuran. The strategy permits the synthesis of several other aromatic analogues of isoaltholactone. Georg Thieme Verlag Stuttgart.

Synthesis and VEGF inhibitory activity of 16,17-pyrazo-annulated steroids

Eight 16,17-pyrazo-annulated steroidal derivatives were synthesized and evaluated in vitro vascular endothelial growth factor (VEGF) inhibitory activity with 2-methoxyestradiol (2-ME) as the reference compound. Most of the compounds showed potent VEGF inhibitory activity with EC50 values of micromolar or submicromolar range. Among them, the compounds 3 and 8 exhibited similar EC50 values and obviously better TI values compared with 2-ME.

African elephants use plant odours to make foraging decisions across multiple spatial scales

Mammalian herbivores are known to be extremely selective when foraging, but little is known about the mechanisms governing the selection of patches and, at a finer scale, individual plants. Visual examination and direct sampling of the vegetation have previously been suggested, but olfactory cues have seldom been considered. We examined the use of olfactory cues by foraging African elephants, Loxodonta africana, and asked whether they use plant odours to select specific patches or plants when making feeding decisions. Scent-based choice experiments between various preferred and nonpreferred plants were conducted across two spatial scales (between plants and between patches). We used coupled gas chromatography?mass spectrometry (GC?MS) analysis of headspace extracts of volatile organic compounds emitted by the different plant species to explore similarities among the overall odour profiles of each species. We found that elephants selected their preferred plant species across both spatial scales, probably using differences in plant odour profiles. The ability to differentiate between plant odours allowed elephants to reduce their search time by targeting preferred plant species both within a feeding station and between patches. This suggests that olfactory cues probably play an important role in driving herbivore foraging decisions across multiple spatial scales.

Design, synthesis, and structure-activity relationships of macrocyclic hydroxamic acids that inhibit tumor necrosis factor alpha release in vitro and in vivo

To search for TNF-alpha (tumor necrosis factor alpha) converting enzyme (TACE) inhibitors, we designed a new class of macrocyclic hydroxamic acids by linking the P1 and P2? residues of acyclic anti-succinate-based hydroxamic acids. A variety of residues including amide, carbamate, alkyl, sulfonamido, Boc-amino, and amino were found to be suitable P1 P1-P2? linkers. With an N-methylamide at P3?, the 13-16-membered macrocycles prepared exhibited low micromolar activities in the inhibition of TNF-alpha release from LPS-stimulated human whole blood. Further elaboration in the P3?-P4? area using the cyclophane and cyclic carbamate templates led to the identification of a number of potent analogues with IC50 values of ?0.2 muM in whole blood assay (WBA). Although the P3? area can accommodate a broad array of structurally diversified functional groups including polar residues, hydrophobic residues, and amino and carboxylic acid moieties, in both the cyclophane series and the cyclic carbamate series, a glycine residue at P3? was identified as a critical structural component to achieve both good in vitro potency and good oral activity. With a glycine residue at P3?, an N-methylamide at P4? provided the best cyclophane analogue, SL422 (WBA IC50 = 0.22 muM, LPS-mouse ED50 = 15 mg/kg, po), whereas a morpholinylamide at P4? afforded the most potent and most orally active cyclic carbamate analogue, SP057 (WBAIC50 = 0.067 muM, LPS-mouse ED50 = 2.3 mg/kg, po). Further profiling for SL422 and SP057 showed that these macrocyclic compounds are potent TACE inhibitors, with Ki values of 12 and 4.2 nM in the porcine TACE assay, and are broad-spectrum MMP inhibitors. Pharmacokinetic studies in beagle dogs revealed that SL422 and SP057 are orally bioavailable, with oral bioavailabilities of 11% and 23%, respectively.

Design, synthesis, and kinetic evaluation of high-affinity FKBP ligands and the X-ray crystal structures of their complexes with FKBP 12

The design and synthesis of high-affinity FKBP12 ligands is described. These compounds potently inhibit the cis-trans-peptidylprolyl isomerase (rotamase) activity catalyzed by FKBP12 with inhibition constants (Ki,app) as low as 1 nM, yet they possess remarkable structural simplicity relative to FK506 and rapamycin, from which they are conceptually derived. The atomic structures of three FKBP12-ligand complexes and of one unbound ligand were determined by X-ray crystallography and are compared to the FKBP12-FK506 and FKBP12-rapamycin complexes.

Porous nanomaterials as green catalyst for the conversion of biomass to bioenergy

Natural fossil fuel is the prime resource of energy and with the rapid technological development its reserve is depleting at an alarming rate. To overcome this concern bio-refinery is the most emerging and necessary approach, where liquid fuels and related demanding fine chemicals can be derived very effectively from biomass via platform chemical 5-hydroxymethylfurfural (HMF). HMF, furfural and 2,5-furandicarboxylic acid (FDCA) can be derived from biomass via several catalytic processes. Thus the objective of this review is to summarize various catalytic methods to produce 5-hydroxymethylfurfural (HMF) the precursor of 2,5-dimethylfuran (DMF) from a variety of monomeric bioresources such as glucose, fructose, dimeric (sucrose) and also polymeric carbohydrates like starch, cellulose and biomass derived carbohydrates (raw biomass). High surface acidity and porous nanostructures (high surface area) of the nanomaterials play crucial role in these heterogeneous catalytic processes. Several nanoporous solid acid catalysts like porous resin, micro/mesoporous carbons, microporous zeolites, mesoporous metal oxides, functionalized mesoporous silicas and porous organic polymers employed in the selective biomass conversion reactions are discussed in detail in this review. Bifunctional catalysts, MOFs and metal phosphonates with functionalised surfaces in comparison to those of the conventional solid acid catalysts are also discussed in-depth.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of (cis-Tetrahydrofuran-2,5-diyl)dimethanol, you can also check out more blogs about2144-40-3

Gas-phase Protonation of Unsaturated Ethers: Experimental and Theoretical Study of 2,3- and 2,5-Dihydrofuran and Related Compounds

The protonation of 2,3- and 2,5-dihydrofuran is examined in gas-phase equilibrium proton transfer reactions conducted in an ion cyclotron resonance spectrometer.The thermodynamically favoured site of protonation in the two compounds is seen to be different: whereas the first isomer forms a carbocation upon protonation, the second isomer protonates on the oxygen atom an oxonium ion.The results obtained with substituted derivatives and with linear analogues confirm these conclusions.Molecular orbital calculations on the various structures for protonated bases are performed at the 4-31G level with correction for configuration interaction effects and at the 4-31G* level.The latter basis set provides the best results owing to the introduction of d-type orbitals on the oxygen atom.The calculation results substantiate the experimental observations and provide details on the molecular structure of the protonated species.
