Description

a-Trifluoromethyl substituted amino acids are very attractive compounds for the design of biologically active compounds [1]. The incorporation of trifluoromethyl groups carrying building blocks into peptides can result in increase chemical and thermal stability, increased resistance to degradation by proteases [2], and enhanced lipophilicity, i.e. better affinity to lipid membranes. Stabilization of particular conformations and auto-assembly [3] can be induced. Also useful as label for 19F-NMR studies [4]. References: [1] V. P. Kukhar, V. A.
