Figure 2From: Antiviral activity of α-helical stapled peptides designed from the HIV-1 capsid dimerization domainCircular dichroism (CD) spectroscopy study of NYAD-201, its linear analog NYAD-209 and a double mutant (W184A and M185A) of NYAD-201 (NYAD-233) to determine their secondary structure. NYAD-201 and NYAD-233 showed characteristic minima at 208 and 222 nm indicating its α-helical structure whereas the linear analog displayed no minima in those regions.Back to article page
