Chemical composition and in vitro anti-algal activity of Potamogeton crispus and Myriophyllum spicatum extracts

The aim of this work was to investigate and compare the phytochemical constituents and anti-algal activities of crude extracts from dry macrophytes species, Potamogeton crispus and Myriophyllum spicatum. Organic solvents differed in polarity including petroleum ether, methylene chloride, chloroform, acetone and methanol were used to extract the phytochemical compounds and gas chromatograph?mass spectrometry (GC?MS) analyzer was used for the detection of these compounds. Generally, the results indicated that the composition and mass fraction of phytochemical constituents varied with plant species and extraction solvents. The growth inhibition effects of separate and mixed plants extracts on Pseudokirchneriella subcapitata were studied. In addition, the effects of mixed extracts on ten taxonomically different freshwater microalgae species, using the single-species and mixed culture species tests were also studied. Among the five different extracts tested chloroform extract and mixed extracts of the two plant species showed the highest anti-algal potential with P. subcapitata. The sensitivity of microalgae species tested in single-species cultures to P. crispus and M. spicatum extracts found to be group-specific, in which cyanophyte Anabaena flos-aquae var. treleasei and the diatoms Gomphoneis eriense var. apiculate and Tryblionella hungarica were more sensitive compared to the tested green microalgae species. In addition, the inhibitory effects of macrophyte extracts decreased for the mixed microalgae cultures. The extracts of P. crispus and M. spicatum showed the presence of some bioactive compounds that could contribute toward the phyto-algicidal properties of these plants.

Intramolecular Photocyclization of N-<(2-Haloaryl)methyl>pyridinium and N-(Arylmethyl)-2-halopyridinium Salts

Various N-<(2-haloaryl)methyl>pyridinium, N-(arylmethyl)-2-halopyridinium and N-(2-halobenzyl)isoquinolinium salts have been synthesized and their intramolecular photocyclization reactions studied.Upon irradiation the aqueous solution of N-<(2-haloaryl)methyl>pyridinium and N-arylmethyl-2-halopyridinium salts 1, 2 were cyclized to give isoindolium salts.In contrast to the pyridinium salts 1, 2, the aqueous solution of N-(2-halobenzyl)isoquinolinium salts 3 appear not to undergo photocyclization.N-Benzyl-2-chloropyridinium salts 1c is more reactive than N-(2-chlorobenzyl)pyridinium salt 1a in the photocyclization.N-(2-Chlorobenzyl)-2-chloropyridinium salt 1d is three times more reactive than 1c.A mechanism of ?-complex formation of the halogen moiety of the pyridinium ring with the phenyl ring is suggested for the reactive pyridinium salt.The triplet energy of the isoquinolinium salts 3 is too low to photocyclize.

Fluoride anion recognition by a multifunctional urea derivative: An experimental and theoretical study

In this work we demonstrate the ability of a multifaceted N,N?-disubstituted urea to selectively recognize fluoride anion (F?) among other halides. This additional function is now added to its already reported organocatalytic and organogelator properties. The signaling mechanism relies on the formation of a charge-transfer (CT) complex between the urea-based sensor and F? in the ground state with a high association constant as demonstrated by absorption and fluorescence spectroscopy. The nature of the hydrogen bonding interaction between the sensor and F? was established by 1H-NMR studies and theoretical calculations. Moreover, the recovery of the sensor was achieved by addition of methanol.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 126456-43-7, and how the biochemistry of the body works.Electric Literature of 126456-43-7

Lobelane analogues as novel ligands for the vesicular monoamine transporter-2

A series of lobelane analogues has been synthesized and their structure-activity relationships at the vesicular monoamine transporter-2 (VMAT2) have been evaluated. The most potent analogues in this series were the cis-2,6-piperidino analogues, 25b, 27b, 28b, and 30b, with Ki values ranging from 430 to 580 nM.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Conformational stability of oligoferrocene oligoamide foldamers

Organometallic oligoamides built from three to four ferrocene amino acid units (H-Fca-OH, 1-amino-1′-ferrocene carboxylic acid) fold into hydrogen bonded secondary structures featuring eight-membered rings by cooperative hydrogen bonds. NMR studies and DFT calculations (CAM-B3LYP, LANL2DZ, IEFPCM (THF)) reveal that the organometallic zigzag foldamer structures are highly resistant toward denaturation by hydrogen bond acceptors such as dimethyl sulfoxide and 2,4-lutidine. Replacing one ferrocene amino acid unit by the organic alpha-amino acid glycine at the C-terminal end (Fca ? Gly) significantly destabilizes the secondary zigzag structure facilitating denaturation by DMSO. Highly stabilized ordered poly(Fca) architectures are very attractive for future applications of switchable hydrogen-bonded redox-active materials.

Dynamic kinetic resolution and desymmetrization processes: A straightforward methodology for the enantioselective synthesis of piperidines

A straightforward procedure for the synthesis of enantiopure polysubstituted piperidines is reported. It involves the direct generation of chiral non-racemic oxazolo[3,2-a]piperidone lactams that already incorporate carbon substituents on the heterocyclic ring and the subsequent removal of the chiral auxiliary. The key step is a cyclocondensation reaction of (R)-phenylglycinol or other amino alcohols with racemic or prochiral delta-oxo (di)acid derivatives in highly stereoselective processes involving dynamic kinetic resolution and/or desymmetrization of diastereotopic or enantiotopic ester groups.

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.Quality Control of (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol, you can also check out more blogs about126456-43-7
