Asymmetric synthesis of phenylbis(glycines)

Synthesis and applications of symmetric amino acid derivatives

Symmetric α-amino acid derivatives can be used for the synthesis of intermolecularly linked peptides such as dimer-type peptides, and modified peptides in which two amino acids are intramolecularly linked. They are also synthetic intermediates for the total synthesis of natural products and functional molecules. These symmetric amino acid derivatives must be prepared based on organic synthesis. It is necessary to develop an optimal synthetic strategy for constructing the target symmetric amino acid derivative. In this review, we will introduce strategies for synthesizing symmetric amino acid derivatives. Additionally, selected applications of these amino acids in the life sciences will be described.

Nitrogen positional scanning in tetramines active against HIV-1 as potential CXCR4 inhibitors

The paradigm, derived from bicyclams, by which it is necessary to use the p-phenylene moiety as the central core in order to achieve high HIV-1 antiviral activities has been reexamined for structures 4.
