H-Arg(Pbf)-OH (cas: 200115-86-2) belongs to benzofurans derivatives. Benzofuran is a core structural unit found in many naturally occurring compounds with multidirectional biological activities. As benzofurans are prone to undergo ring opening of the heterocycle, examples of reduction of this type of aromatics by using dissolving metals are rather scarce.Electric Literature of C19H30N4O5S

And the article was included in Angewandte Chemie, International Edition in 2011.Electric Literature of C19H30N4O5S This article mentions the following:

The authors report the design and evaluation of amphipathic homochiral L-cyclic peptides for potential applications as cell-penetrating peptides or mol. transporters of bioactive compounds To examine the potential application of the cyclic peptides as mol. transporters, a model experiment was performed with lamivudine. In the experiment, the researchers used many compounds, for example, H-Arg(Pbf)-OH (cas: 200115-86-2Electric Literature of C19H30N4O5S).
