Design, Synthesis, and Antimicrobial Activity of Novel 6-Oxopyrimidin-1(6H)-yl Benzamide Derivatives

A series of novel 1-(benzamide)-N-cyclopropyl-2-(amino substituted)-6-oxo-1,6-dihydropyrimidine-5-carboxamide derivatives is synthesised and characterized by IR, 1H and 13C NMR, and mass spectra. The synthesized compounds 6a-6j and 8a-8j are screened for their in vitro antimicrobial activity against two Grampositive (Staphylococcus aureus, Bacillus subtilis) and two Gram-negative bacteria (Escherichia coli, Klebesiella aerogenes), and two pathogenic fungi (Aspergillus flavus, Fusarium oxysporum). Most of the compounds demonstrate good to excellent antimicrobial activity in comparison with the standard drugs ciproflaxin and hymexazole. Among the screened compounds morpholine substituted dihydropyrimidone carboxamide 8j is determined to be the most potent anti-bacterial agent.

A novel class of geldanamycin derivatives as HCV replication inhibitors targeting on Hsp90: Synthesis, structure-activity relationships and anti-HCV activity in GS4.3 replicon cells

A novel class of geldanamycin (GA) derivatives as hepatitis C virus (HCV) replication inhibitors has been synthesized and their anti-HCV activities were evaluated in GS4.3 HCV replicon cells. Most of the synthesized compounds demonstrated potential activities against HCV in vitro. Substitution with an aliphatic cyclic group (2b) and polar phosphate group (2f) at the 17 position of GA resulted in more potent inhibitory activity. The configurations of the tetrahydrofurfurylamino (THFM) substituents obviously affected their antiviral activities. The 2b with a 2?-(R)-THFM group at the 17 position showed much potent activity and higher selectivity than its 2?-(S) and 2?-(R, S) epimers. In the tested GA derivatives, 2b and 2f show the most potential leading compounds for development of novel anti-HCV agents.

Efficient hydrogenolysis of 5-hydroxymethylfurfural to 2,5-dimethylfuran over a cobalt and copper bimetallic catalyst on N-graphene-modified Al2O3

2,5-Dimethylfuran (DMF) is an important candidate for liquid fuels and can be produced from biomass derived 5-hydroxymethylfurfural (HMF). Efficient transformation of HMF to DMF has not been achieved over a non-noble catalyst under milder conditions. Herein, we developed a copper and cobalt bimetallic nanoparticle catalyst supported on N-graphene-modified Al2O3 (CuCo/NGr/alpha-Al2O3). It was found that CuCo/NGr/alpha-Al2O3 could catalyze the conversion of HMF to DMF effectively and the yield of DMF could reach 99%. The catalyst was completely not active for the hydrogenation of the C=C bond in furan and thus no 2,5-bis(hydroxymethyl)tetrahydrofuran (DHTHF) and 2,5-dimethyltetrahydrofuran (DMTHF) were detected.

Identification of volatile organic compounds in human cerumen

We report here the initial examination of volatile organic compounds (VOCs) emanating from human earwax (cerumen). Recent studies link a single nucleotide polymorphism (SNP) in the adenosine triphosphate (ATP) binding cassette, sub-family C, member 11 gene (ABCC11) to the production of different types of axillary odorants and cerumen. ABCC11 encodes an ATP-driven efflux pump protein that plays an important function in ceruminous apocrine glands of the auditory canal and the secretion of axillary odor precursors. The type of cerumen and underarm odor produced by East Asians differ markedly from that produced by non-Asians. In this initial report we find that both groups emit many of the same VOCs but differ significantly in the amounts produced. The principal odorants are volatile organic C2-to-C6 acids. The physical appearance of cerumen from the two groups also matches previously reported ethnic differences, viz., cerumen from East Asians appears dry and white while that from non-Asians is typically wet and yellowish-brown.

One of the oldest and most widely used commercial enzyme inhibitors is aspirin, SDS of cas: 105-21-5, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 105-21-5

THE EFFECTS OF SUBSTITUENS AND SOLVENT POLARITY ON PHOTOCHEMICAL <1.3> SIGMATROPIC SHIFTS. EXPERIMENTAL EVIDENCE IN FAVOUR OF THE OCCURRENCE OF SUDDEN POLARIZATION IN ACYCLIC ALKENES

Furher experimental evidence regarding the occurence of sudden polarization in acyclic alkenes is presented.It is shown that the yield of formation of the product derived from an intramolecular photochemical <1,3>-OH shift in the 1 is dependent only on the polarity of the solvent employed.This result could be well explained in terms of a stabilization of the zwitterionic intermediate formed upon irradiation of 1 by reorientation polarization of the dipole solvent molecules.Besides this, it was found that replacement of the alkyl group at the terminal carbon atom of the C3-C9 exocyclic double bond in 1 by a phenyl substituent led to the occurence of a photochemical <1.3>-H shift.This directive effect of the substituents at the exocyclic double bond could be well explained on the basis of the sudden polarization model.

Preparation of amines

Disclosed is a process for the preparation of an amine by contacting in a reaction zone a water-soluble aldehyde, water, ammonia and hydrogen in the presence of a supported ruthenium catalyst at elevated temperature and pressure. The process is particularly useful for the preparation of 3-(aminomethyl)tetrahydrofuran by contacting an aqueous solution of 3-formyltetrahydrofuran with ammonia and hydrogen at elevated temperature and pressure in the presence of a supported ruthenium catalyst. The use of a supported ruthenium catalyst has been found to avoid the problem of catalyst leaching encountered when a nickel catalyst is used.

Hydrogenation of furfural to butanol and pentanols for renewable gasoline blendstocks

Butanols and pentanols can be prepared in high selectivity from furfural reduction in a catalyzed continuous hydrogenation process. The catalyst should have bifunctional activity with both hydrogenation and acidic sites. A co-solvent is necessary to mitigate furfural plugging during extended operation. Both ethanol and hydroxymethyl tetrahydrofuran are suitable co-solvents. Hydroxymethyl tetrahydrofuran is an intermediate in the reduction of furfural to alcohols and higher overall yields from furfural can be obtained by recycling unreacted hydroxymethyl tetrahydrofuran for use as the reaction solvent.

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 15833-61-1, help many people in the next few years.Formula: C5H10O2
