Reagents for Peptide Synthesis

Fmoc-Pro-OH is a proline derivative.

Fmoc-L-Val-OH is a valine derivative.

Fmoc-Ile-OH is an isoleucine derivative.

Fmoc-His(Trt)-OH is a histidine derivative with a trityl (Trt) group protecting the His side chain. Fmoc-His(Trt)-OH also has an Fmoc group protecting the α-NH₂ group. Fmoc-His(Trt)-OH can be used in solid-phase peptide synthesis to prevent racemization and byproduct formation. Fmoc-His(Trt)-OH acts as a protected histidine precursor in solid-phase peptide synthesis (SPPS), participating in peptide chain construction through amide bond formation. Fmoc-His(Trt)-OH can be precisely incorporated into the target peptide sequence, ensuring correct peptide chain synthesis and reducing impurity formation. Fmoc-His(Trt)-OH is mainly used in the solid-phase synthesis research of pharmaceutical peptides and bioactive peptides, and is particularly suitable for the preparation of peptide drugs requiring precise control of histidine configuration.

DL-Serine hydroxamate is a serine derivative.

tert-Butyl 2-aminoacetate is a Glycine (HY-Y0966) derivative.

4-Chloro-L-phenylalanine (L-PCPA) is a tryptophan hydroxylase inhibitor targeting TPH1 and TPH2, with the activity of blocking serotonin biosynthesis. 4-Chloro-L-phenylalanine reduces the levels of serotonin and its metabolites in the brain without impairing the survival of serotonergic neurons. 4-Chloro-L-phenylalanine enhances anhedonic, depression-like and anxiety-like behaviors in mice with depleted noradrenergic and dopaminergic neurons. 4-Chloro-L-phenylalanine acts as a decarboxylation substrate for aromatic L-amino acid decarboxylase from Bacillus atrophaeus. 4-Chloro-L-phenylalanine can be used in studies related to Parkinson's disease.

Nα,Nα-Bis(carboxymethyl)-L-lysine is a competitive inhibitor of bitter taste receptor 4, with an IC₅₀ of 59 nM. Nα,Nα-Bis(carboxymethyl)-L-lysine can be used in bitter receptors related study.

Fmoc-Lys-OH is a lysine derivative.

Fmoc-Pra-OH is a Glycine (HY-Y0966) derivative. Fmoc-Pra-OH is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

L-Cystine dihydrochloride is the dihydrochloride salt form of L-Cystine (HY-N0394). L-Cystine dihydrochloride elevates Nrf2 protein expression and activates Nrf2 transcription factor. L-cystine dihydrochloride reduces ROS generation and protects against oxidant- or Doxorubicin (HY-15142A)-induced apoptosis. L-Cystine dihydrochloride combined with L-theanine (HY-15121) enhances the production of antigen-specific IgG by increasing glutathione (GSH) levels and T helper 2 (Th2) mediated responses in mice. L-Cystine dihydrochloride is promising for research of cystinuria and kidney stones

Z-LYS-SBZL (monohydrochloride) is a lysine derivative.

Boc-Glycine is a Glycine (HY-Y0966) derivative.

Fmoc-Glu(OAll)-OH is a glutamic acid derivative.

Fmoc-Aib-OH is an alanine derivative.

Fmoc-His(Boc)-OH is a histidine derivative.

Fmoc-Lys(Mtt)-OH is a lysine derivative.

L-Selenocystine is a selenium-containing amino acid. L-Selenocystine has redox properties. L-Selenocystine is cytotoxic to various tumor cells and can induce the production of ROS and apoptosis. L-Selenocystine can block the Nrf2 and autophagy pathways. L-Selenocystine has anti-tumor activity.

Glycine tert-butyl ester hydrochloride is a Glycine (HY-Y0966) derivative.

Fmoc-α-Me-Leu-OH is a leucine derivative with an Fmoc protecting group, which can be used to synthesize peptides with oxytocin receptor agonist activity.
