Grupos de protecção
Os grupos de proteção são usados na síntese orgânica para mascarar temporariamente grupos funcionais reativos, permitindo que reações seletivas ocoam sem interferência. Esses grupos são essenciais para processos de síntese em várias etapas, garantindo que partes específicas da molécula permaneçam não reativas enquanto outras reações são realizadas. Nesta seção, você encontrará uma variedade de grupos de proteção adequados para diferentes grupos funcionais, juntamente com reagentes para sua introdução e remoção. Na CymitQuimica, oferecemos uma gama abrangente de grupos de proteção de alta qualidade para facilitar suas estratégias sintéticas.

CAS:Boc-D-Tyr(tBu)-OH is a natural product that is an amphipathic molecule with a cyclic structure. It has been shown to be able to inhibit the growth of bacteria, such as Staphylococcus aureus and Escherichia coli, by acting as an antibiotic. Boc-D-Tyr(tBu)-OH inhibits the synthesis of peptides by binding to the ribosome and blocking peptide elongation. This molecule also inhibits peptide synthesis by interacting with the aminoacyl site on the ribosome and preventing it from binding with amino acids. Boc-D-Tyr(tBu)-OH is synthesized in two stages: solid phase peptide synthesis and nucleophilic activation. The decapeptides are then purified and characterized based on their function.Fórmula:C18H27NO5Pureza:Min. 95%Cor e Forma:PowderPeso molecular:337.41 g/mol4-tert-Butyl-L-phenylalanine
CAS:4-tert-Butyl-L-phenylalanine is a synthetically created antigen with the ability to interact with red blood cells. It has been shown to be a potent probe for the detection of P. falciparum, and can be used as an affinity reagent for the isolation and identification of mutations in the c-terminal region of this protein. 4-tert-Butyl-L-phenylalanine also interacts with P. falciparum apical membrane proteins, which are specific to this type of parasite. This interaction may play a role in its invasion into red blood cells, which is what causes malaria infection.Fórmula:C13H19NO2Pureza:Min. 95%Cor e Forma:White PowderPeso molecular:221.3 g/molBenzene, 1-(chlorodiphenylmethyl)-4-methoxy-

CAS:Fmoc-glycinol is a synthetase that is used to synthesize glycinol conjugates. It binds to the receptor on Gram-positive bacteria and blocks the synthesis of bacterial cell wall, leading to cell death. Fmoc-glycinol has been shown to have high binding constants with amines and an acyl chain, which allows it to bind with antigen. Fmoc-glycinol also has strong nucleophilic properties that allow it to react with chloride ions in water and other polar solvents. This reaction mechanism leads to the formation of a new bond between two molecules, which is called a glycinol linkage.Fórmula:C17H17NO3Pureza:Min. 95%Cor e Forma:White PowderPeso molecular:283.32 g/molSilane, chlorodimethyloctyl-

CAS:Fmoc-L-Cys(StBu)-OH is a synthetic molecule that is used in pharmaceutical formulations. It can be synthesized from Fmoc-L-Cys and L-serine methyl ester by the chemical ligation of the two molecules. The chloride group at the end of this molecule provides a functional group for conjugation with other biomolecules, such as fatty acids. This molecule has been shown to have high purity with an isolated yield of about 98%.Fórmula:C22H25NO4S2Pureza:Min. 98 Area-%Cor e Forma:PowderPeso molecular:431.57 g/molAllyltriethylsilane

CAS:Boc-L-prolinal is a stereoselective enolate that has been used in the synthesis of organometallic compounds. It is also used in the preparation of monoclonal antibodies, which are proteins that are produced by the immune system to help fight off infections. Boc-L-prolinal has been shown to be an effective agent for treating many cancers, including breast cancer and melanoma. In addition, it has been shown to inhibit epidermal growth factor (EGF) and other growth factors, which may be due to its ability to induce apoptotic signaling. Boc-L-prolinal also contains a carbonyl group, which can undergo acidolysis reactions with nucleophiles such as water or alcohols.Fórmula:C10H17NO3Pureza:Min. 95%Cor e Forma:Colorless Clear LiquidPeso molecular:199.25 g/molN-(9-Fluorenylmethoxycarbonyloxy)succinimide
