From: Chiral Sulfoxide-Induced Single Turn Peptide α-Helicity
(a) CD spectra of (R)-diastereomer 19B-24B. (b) CD spectra of sulfone-containing peptides 25 and 26 show minimal helix contents. (c) CD spectroscopy was performed for (R)-19B at increasing temperatures. Its helicity decreased slightly as temperature increased (d) At 65 °C, (R)-19B retained 75% of the helicity that it showed at 30 °C. CD spectroscopy was performed in 10 mM PBS (pH = 7.4) buffer at 25 °C.
