Two copper(II) complexes with ligands derived from β-amino acids, 2-(1-aminocyclohexyl)acetic acid L1 and 2-(1-amino-4-(tert-butyl)cyclohexyl)acetic acid L2, were synthesized and characterized by microanalysis, infrared, UV–Vis and EPR spectra. The spectr

The present study describes the solid-state conformation of αβ hybrid peptides, Boc-Leu-β3, 3-Ac6c-OH, P1; Boc-Leu-β3, 3-Ac6c-Leu-β3, 3-Ac6c-OMe, P2; and Boc-Leu-β3, 3-Ac6c-Leu-β3, 3-Ac6c-Leu-OMe, P3. The dipeptide P1 adopts extended conformations, whereas tetrapeptide P2 and pentapeptide P3 favor a helical conformation stabilized by mixed types of C11/C9 intramolecular hydrogen bonds. In peptide P3, the amino group of β3, 3-Ac6c(2) and β3, 3-Ac6c(4) residues occupies axial orientation, whereas in P2 it occupies axial and equatorial orientations for residues β3, 3-Ac6c(2) and β3, 3-Ac6c(4), respectively. The self-assembly of P3 forms channels filled with solvent molecules that present interesting patterns.

The present work describes the anti-invasive effect of conjugate BC06, a novel conjugate of EPA, (2E,4E)-4-(benzo[d][1,3]dioxol-5-ylmethylene) hex-2-enoic acid with β,β-disubstituted-β-amino acid, β3,3-Pip-OH (2-(4-aminopiperidin-4-yl)acetic acid), in human pancreatic carcinoma. The conjugate BC06 inhibited invasion and migration of PANC-1 cells in wound healing, matrigel invasion, and gelatin degradation assays. Apart from suppressing PI3K/Akt/NF-kB signaling, which is involved in the up-regulation of matrix metalloproteinases, our study also demonstrated that dose-dependent treatment of BC06 results in the upregulation of TIMP-1 and E-cadherin expression. Further, BC06 was found to be inhibiting the metastatic ability of PANC-1 cells by reducing MMP-2 and MMP-9 expression. These findings suggest that EPA conjugate with β3,3-Pip-OH, BC06, may be used as an anti-invasive agent against human pancreatic carcinoma.

The Rodionov reaction of 49 available aliphatic and aromatic aldehydes with malonic acid and ammonium acetate in alcoholic medium, resulting in formation of β-amino acids, propenoic, and ylidenemalonic acids, was studied. Certain regioselectivity regularities of the reaction were revealed. Among the variety of ketones studied, cyclohexanone is the only whose reaction yields a β-amino acid. Unusual dehydrofluorination of 6-chloro-2-fluorocinnamic acid under the Rodionov reaction was discovered. 2005 Pleiades Publishing, Inc.

, (2008/06/13)
β-Aminopenicillins, Salts and Esters are described having a wide spectrum of activity against Gram-positive and Gram-negative organisms. The β-aminopenicillins are derivatives of 6-amino-penicillanic acid and the procedure for preparing the β-aminopenicillins is set forth. β-aminopenicillins are characterized by having in the 6-position side chain a cycloalkyl ring of 5 - 7 carbon atoms particularly cyclopentyl, cyclohexyl or cycloheptyl.
