Usage

General Description

Fmoc-3-chloro-L-phenylalanine is a chemical compound used in the synthesis of peptides and proteins. It is a derivative of the amino acid phenylalanine, in which a 3-chloro substituent is attached to the phenyl ring. The Fmoc (9-fluorenylmethyloxycarbonyl) group is commonly used as a protective group for amino acids in peptide synthesis. Fmoc-3-chloro-L-phenylalanine is often used in solid-phase peptide synthesis as a building block for incorporating the 3-chloro-L-phenylalanine residue into the peptide chain. Fmoc-3-chloro-L-phenylalanine plays a crucial role in the development of new drug molecules and in the study of peptide-ligand interactions in biochemical research.

Novel selective inhibitors of the interaction of individual nuclear hormone receptors with a mutually shared steroid receptor coactivator 2

Nuclear hormone receptor (NR) signaling, currently a therapeutic target in multiple diseases, involves an ordered series of protein interactions to regulate transcription in response to changing hormone levels. Later steps in the process of ligand-dependent signaling are driven by a highly conserved interaction between the NRs and the steroid receptor coactivators (SRCs) that is effected by a conserved interaction motif (L1XXL2L3), known as an NR box. Using computational design and combinatorial chemistry, we have produced novel ∞-helical proteomimetics of the second NR box of SRC2 that exploit structural differences between human estrogen receptor ∞ (hER∞), human estrogen receptor β (hERβ), and human thyroid hormone receptor β (hTRβ). The resulting library sequentially replaced each leucine with non-natural side chains. Screening this library using a quantitative competition assay revealed compounds that selectively inhibit the interaction of SRC2-2 with each individual NR in preference to its interaction with the other NR. This approach generated highly selective compounds from one that had no specificity for a particular family member. These compounds represent the first family-member-selective competitive inhibitors of the protein interactions of transcription factors. Copyright
