Abstract
Three-arm helices (TA16, TA8), in which three hydrophobic helical peptides were tethered together at their C-terminals, were synthesized, and self-assembling property in water was investigated. TA16 (m.w. = 5228) was dispersed easily in water even though this compound has no explicit hydrophilic moiety in the molecule. Dynamic light scattering measurement and transmission electron microscopy images of water dispersions of TA16 and TA8 revealed that spherical assemblies with diameter of 70 nm (TA16) and 100 nm (TA8) were formed. The central tertiary amine moiety in TA16 and TA8 should act as a hydrophilic part due to the convergent point of the three negatively polarized C-terminals of helices.
