In the present work, we describe the synthesis and the temperature-dependent behavior of photoreactive membrane lipids as well as their capability to study peptide-lipid interactions. The modified phospholipids contained an azide group either in the middle part or at the end of an alkyl chain and also differed in the linkage (ester vs. ether) of the 2nd alkyl chain. The temperature-dependent aggregation behavior of the azidolipids was studied using differential scanning calorimetry (DSC), FTIR spectroscopy, and SAXS. Aggregate structures were visualized by stain and cryo-transmission electron microscopy (TEM) and were further characterized by dynamic light scattering (DLS). We showed that the position of the azide group and the type of linkage of the alkyl chain at the sn-2 position of the glycerol influenced the type of aggregates formed as well as their long-term stability: azidolipids P10AzSPC and r12AzSHPC showed the formation of extrudable liposomes, which were stable in size during storage. In contrast, azidolipids that carry a terminal azido moiety either formed extrudable liposomes, which showed time-dependent vesicle fusion (P15AzPdPC), or self-assembled in large sheet-like, non-extrudable aggregates (r15AzPdHPC) where the lipid mols. were arranged in an interdigitated orientation at temperatures below the Tm (L灏?/sub>I phase). Finally, a P10AzSPC:DMPC mixture was used for photochem.-induced crosslinking experiments with a transmembrane peptide (WAL-peptide) to demonstrate the applicability of the azidolipids for the anal. of peptide/lipid interactions. The efficiency of photocrosslinking was monitored by attenuated total reflection IR spectroscopy and mass spectrometry. In the experiment, the researchers used many compounds, for example, 15-Bromopentadecanoic acid (cas: 56523-59-2Computed Properties of C15H29BrO2).
15-Bromopentadecanoic acid (cas: 56523-59-2) belongs to organobromine compounds. Organo bromine compounds are versatile compounds and are widely used in diverse fields. Organo bromine derivatives are used in the dye sector, as an indicator in analytical chemistry (Bromothymol blue is a popular indicator). Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin.
