Usage

General Description

FMOC-L-Phenylalanine Chloride, often abbreviated as Fmoc-L-Phe-Cl, is a chemical compound used primarily in peptide synthesis. It is an amino acid derivative and is characterized by the presence of a chlorine atom attached to it, hence the name. The FMOC (9-fluorenylmethyloxycarbonyl) group serves as a protective group for the amino acid during synthesis, preventing unwanted side reactions. FMOC-L-PHENYLALANYL CHLORIDE is typically used in laboratory settings, specifically in biochemical and pharmaceutical research, due to its fundamental role in creating complex proteins and peptides. Usage of this compound requires specialized knowledge and care due to its potential reactivity.

Bioinspired honokiol analogs and their evaluation for activity on the norepinephrine transporter

In traditional Asian medicinal systems, preparations of the root and stem bark of Magnolia species are widely used to treat anxiety and other nervous disturbances. The biphenyl-type neolignans honokiol and magnolol are the main constituents of Magnolia bark extracts. In the central nervous system, Magnolia bark preparations that contain honokiol are thought to primarily interact with -aminobutyric acid A (GABAA) receptors. However, stress responses inherently involve the noradrenergic system, which has not been investigated in the pharmacological mechanism of honokiol. We present here interactions of honokiol and other synthesized biphenyl-type neolignans and diphenylmethane analogs with the norepinephrine transporter (NET), which is responsible for the synaptic clearance of norepinephrine and the target of many anxiolytics. Of the synthesized compounds, 16 are new chemical entities, which are fully characterized. The 52 compounds tested show mild, non-potent interactions with NET (IC50 > 100 μM). It is thus likely that the observed anxiolytic effects of, e.g., Magnolia preparations, are not due to direct interaction with the noradrenergic system.

Enantiopure 5-CF3-Proline: Synthesis, Incorporation in Peptides, and Tuning of the Peptide Bond Geometry

The straightforward synthesis of enantiopure 5-(R)-and 5-(S)-trifluoromethylproline is reported. The key steps are a Ruppert-Prakash reagent addition on l-pyroglutamic esters followed by an elimination reaction and a selective reduction. The solution-phase and solid-phase incorporation of this unprotected enantiopure fluorinated amino acid in a short peptide chain was demonstrated. Compared to proline, the CF3 group provides a decrease of the trans to cis amide bond isomerization energy and an increase of the cis conformer population.

One-pot synthesis of Weinreb amides employing 3,3-dichloro-1,2-diphenylcyclopropene (CPI-Cl) as a chlorinating agent

The synthesis of Nα-protected amino alkyl Weinreb amides starting from the corresponding α-amino acids as well as carboxylic acids has been delineated through the in situ generation of acid chlorides using CPI-Cl as a chlorinating agent. The protocol is simple; the reaction conditions employed were mild, and compatible with all the three commonly used urethane protecting groups namely, Boc, Cbz and Fmoc groups. The resulting Weinreb amides are obtained in good yields as optically pure products.
