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.

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

Inhibitors of the protease from human immunodeficiency virus: Synthesis, enzyme inhibition, and antiviral activity of a series of compounds containing the dihydroxyethylene transition-state isostere

A number of potential HIV protease inhibitory peptides that contain the dihydroxyethylene isostere were prepared and evaluated for their enzyme binding affinity and antiviral activity in cell cultures. From the template of a previously reported active peptide A, modifications at the N- and C- terminal groups were assessed for potential maintenance of good inhibitory activity of the resulting peptides. Among the active peptides found, peptide XVIII exhibited potent enzyme inhibitory activity. Interestingly, the previously reported, effective 1(S)-amino-2(R)-hydroxyindan C-terminal group for the preparation of very active HIV protease inhibitory peptides could not be applied to the template of peptide XVIII. Molecular modeling of peptide XVIII was studied using the X-ray crystal structure of peptide A as a starting point in order to study the likely conformation of peptide XVIII in the active-site cleft. Relative binding conformations of peptide A and XVIII were obtained, although the reason for poor binding affinity for a number of congeneric peptides in this report was not straightforwardly apparent. More importantly, however, peptide XVIII was found to exhibit more effective antiviral activity in the HIV-1/PBMC assay than the reference peptide A which was previously reported to be approximately equal in efficacy to the reverse transcriptase inhibitor AZT in this assay.
