Theoretical study of the effective Chemical Shielding Anisotropy (CSA) in peptide backbone, rating the impact of CSAs on the cross-correlated relaxations in L-alanyl-L-alanine.

Ladislav Benda et al.

The journal of physical chemistry. B, 113(15), 5273-5281 (2009-03-24)

The dependence of the effective chemical shielding anisotropy (effective CSA, Deltasigma(eff)) on the phi and psi peptide backbone torsion angles was calculated in the l-alanyl-l-alanine (LALA) peptide using the DFT method. The effects of backbone conformation, molecular charge including the

L-alanyl-L-alanine conformational changes induced by pH as monitored by the Raman optical activity spectra.

Jirí Sebek et al.

The journal of physical chemistry. A, 113(27), 7760-7768 (2009-06-17)

Fine effects of the hydration, charge, and conformational structural changes in L-alanyl-L-alanine (Ala-Ala) dipeptide were studied with the aid of Raman and Raman optical activity (ROA) spectra. The spectra were recorded experimentally and analyzed by means of density functional computations.

Determination of theoretical retention times for peptides analyzed by reversed-phase high-performance liquid chromatography.

Dependence of the L-alanyl-L-alanine conformation on molecular charge determined from ab initio computations and NMR spectra.

Vladimír Sychrovský et al.

The journal of physical chemistry. B, 112(6), 1796-1805 (2008-01-04)

The l-alanyl-l-alanine (AA) molecule behaves differently in acidic, neutral, and basic environments. Because of its molecular flexibility and strong interaction with the aqueous environment, its behavior has to be deduced from the NMR spectra indirectly, using statistical methods and comparison

Intestinal permeability of cyclic peptides: common key backbone motifs identified.

Johannes G Beck et al.

Journal of the American Chemical Society, 134(29), 12125-12133 (2012-06-29)

Insufficient oral bioavailability is considered as a key limitation for the widespread development of peptides as therapeutics. While the oral bioavailability of small organic compounds is often estimated from simple rules, similar rules do not apply to peptides, and even
