N-(9-Fluorenilmetoxicarbonil)-O-terc-butilserina

Descripción:

N-(9-Fluorenilmetoxicarbonil)-O-terc-butilserina, comúnmente conocido como Fmoc-O-t-Bu-Ser, es un derivado de aminoácido protegido ampliamente utilizado en la síntesis de péptidos. Este compuesto presenta un grupo 9-fluorenilmetoxicarbonilo (Fmoc), que sirve como un grupo protector para la funcionalidad amino, permitiendo reacciones selectivas durante el ensamblaje de péptidos. El grupo tert-butilo en la cadena lateral de serina proporciona una hindrance estérica adicional, mejorando la estabilidad de la molécula y previniendo reacciones prematuras. Fmoc-O-t-Bu-Ser se utiliza típicamente en la síntesis de péptidos en fase sólida, donde su estabilidad en condiciones básicas facilita la adición secuencial de aminoácidos. El compuesto es generalmente soluble en disolventes orgánicos como el diclorometano y el dimetilformamida, lo que lo hace adecuado para varios protocolos sintéticos. Su estructura permite la fácil eliminación del grupo Fmoc en condiciones básicas suaves, lo que permite el acoplamiento subsiguiente de otros aminoácidos. En general, Fmoc-O-t-Bu-Ser es un bloque de construcción valioso en el campo de la química de péptidos, contribuyendo a la síntesis eficiente de péptidos y proteínas complejas.

Fmoc-Ser(tBu)-OH

CAS: 71989-33-8

Fmoc-Ser(tBu)-OH is a synthetic peptide that is used in the synthesis of peptides and proteins. It is synthesized by using a stepwise procedure, which involves the use of morpholine as an organic base to deprotonate the carboxylic acid group and then reacting it with trifluoroacetic acid (TFA) to form the corresponding chloroformate ester. The amide bond is formed by reaction with ammonia or an amine. Finally, it can be reacted with hydrochloric acid to form the corresponding hydrochloride salt, which is insoluble in water. Impurities such as thionyl chloride and chloroformate can be removed by washing with methylene chloride or chloroform, respectively. Fmoc-Ser(tBu)-OH has been shown to be selective for the formation of hydrophobic bonds between amino acids and is not reactive toward other side chains on the protein.

Fmoc-Ser(tBu)-OH

CAS: 71989-33-8

Fmoc-Ser(tBu)-OH is a synthetic amino acid that is used in the synthesis of degarelix acetate, an amide ester of the vasodilator, prostaglandin F2α. Degarelix acetate binds to the fibrinogen receptor on the surface of cells and inhibits platelet aggregation. This drug has been shown to be effective in treating prostate cancer by inhibiting epidermal growth factor receptor signaling. It also has immune modulating effects by binding to monoclonal antibodies and altering antibody responses. Fmoc-Ser(tBu)-OH is synthesized from the amino acid serine and t-butyl alcohol, which are combined with trifluoroacetic acid (TFA) and hydroxyl group. The resulting product is then reacted with dansyl chloride or benzoyl chloride (BzCl), which cleaves off one carboxylic acid group from serine, forming an
