Usage

General Description

BOC-ALA-OBZL, also known as tert-Butyloxycarbonyl-L-alanine benzyl ester, is a chemical compound with the molecular formula C17H21NO4. It is used as a building block in peptide synthesis, which is crucial in the production of proteins and enzymes. It essentially serves as a protective group for the acid sensitive amino acid L-alanine during chemical reactions. Its BOC group prevents unwanted side reactions, ensuring the correct formation of peptide bonds. Once the desired synthesis is achieved, the BOC group can be removed. The OBZL or benzyl ester group on the other end of the molecule also serves a protective role, guarding the carboxyl group of the amino acid against premature reactions.

Transition Metal-Free N-Arylation of Amino Acid Esters with Diaryliodonium Salts

A transition metal-free approach for the N-arylation of amino acid derivatives has been developed. Key to this method is the use of unsymmetric diaryliodonium salts with anisyl ligands, which proved important to obtain high chemoselectivity and yields. The scope includes the transfer of both electron deficient, electron rich and sterically hindered aryl groups with a variety of different functional groups. Furthermore, a cyclic diaryliodonium salt was successfully employed in the arylation. The N-arylated products were obtained with retained enantiomeric excess.

Identification of a 4-fluorobenzyl L-valinate amide benzoxaborole (AN11736) as a potential development candidate for the treatment of Animal African Trypanosomiasis (AAT)

Novel L-valinate amide benzoxaboroles and analogues were designed and synthesized for a structure-activity-relationship (SAR) investigation to optimize the growth inhibitory activity against Trypanosoma congolense (T. congolense) and Trypanosoma vivax (T. vivax) parasites. The study identified 4-fluorobenzyl (1-hydroxy-7-methyl-1,3-dihydrobenzo[c][1,2]oxaborole-6-carbonyl)-L-valinate (5, AN11736), which showed IC50 values of 0.15 nM against T. congolense and 1.3 nM against T. vivax, and demonstrated 100% efficacy with a single dose of 10 mg/kg against both T. congolense and T. vivax in mouse models of infection (IP dosing) and in the target animal, cattle, dosed intramuscularly. AN11736 has been advanced to early development studies.
