CAS 3978-80-1

BOC-L-tyrosine

Description:

BOC-L-tyrosine, with the CAS number 3978-80-1, is a derivative of the amino acid tyrosine, characterized by the presence of a tert-butyloxycarbonyl (BOC) protecting group on the amino group. This modification enhances its stability and solubility, making it useful in peptide synthesis and other biochemical applications. BOC-L-tyrosine is typically a white to off-white crystalline powder, and it is soluble in organic solvents such as methanol and dimethyl sulfoxide (DMSO), but less soluble in water. The BOC group can be easily removed under acidic conditions, allowing for the regeneration of the free amino group for further reactions. This compound is often utilized in the synthesis of peptides and proteins, as it allows for the selective protection of functional groups during chemical reactions. Additionally, BOC-L-tyrosine can serve as a building block in the development of pharmaceuticals and biochemicals, contributing to research in medicinal chemistry and drug design.

N-Boc-L-tyrosine

Controlled Product

CAS: 3978-80-1

Applications N-Boc-L-tyrosine is an N-Boc-protected form of L-Tyrosine (T899975). L-Tyrosine is an essential amino acid that exhibits in vitro antioxidant and antiradical activities. L-Tyrosine is used as a precursor to synthesize catecholamines (e.g. Norepinephrine HCl [N674500]) in human keratinocytes, and also for the synthesis of proteins and thyroid hormones.

Boc-Tyr-OH

CAS: 3978-80-1

Boc-Tyr-OH is a tyrosinase inhibitor that binds to the active site of the enzyme and prevents the oxidation of tyrosinase into dopa. It is an enantiopure, cyclic peptide with a chemical stability suitable for use in biological assays. Boc-Tyr-OH has been shown to inhibit the synthesis of melanin by binding to the active site of tyrosinase, which is found in skin cells called melanocytes. The amino function of this compound allows it to be synthesized from amines and hydroxyl group, which can be obtained from trifluoroacetic acid or chromatographic techniques.
