3190-70-3, Name is (S)-4-Isobutyloxazolidine-2,5-dione, belongs to oxazolidine compound, is a common compound. name: (S)-4-Isobutyloxazolidine-2,5-dioneIn an article, once mentioned the new application about 3190-70-3.
Amphiphilic block copolymers of poly(L-leucine-co-ethylene glycol) (PLeum-PEGn) having three different compositions, m:n = 80:23, 57:46, and 66:114, were prepared and spread at an air-water interface to form a stable monolayer. The alpha-helical conformation of PLeu segment in the monolayers was confirmed by FT-IR and circular dichroism measurements. The molecular orientation of PLeu helix rods in the monolayer was estimated by surface pressure-area isotherm and FT-IR reflection absorption spectroscopy measurements. As a result, we confirmed that alpha-helix rod of PLeu segment oriented slightly normal to the membrane plane. Furthermore, it was indicated that each alpha-helical rod in the PLeu57-PEG46 monolayer is effectively oriented normal to the interface compared to that in the PLeu80-PEG23 and PLeu66-PEG114 monolayers.
