Safety of Ethyl 3-bromo-2-oxopropanoate. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Ethyl 3-bromo-2-oxopropanoate, is researched, Molecular C5H7BrO3, CAS is 70-23-5, about Elastase inhibitor cyclotheonellazole A: Total synthesis and in vivo biological evaluation for acute lung injury.

Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) is one of the most common complications in COVID-19. Elastase has been recognized as an important target to prevent ALI/ARDS in the patient of COVID-19. Cyclotheonellazole A (CTL-A) is a natural macrocyclic peptide reported to be a potent elastase inhibitor. Herein, we completed the first total synthesis of CTL-A in 24 linear steps. The key reactions include three-component MAC reactions and two late-stage oxidations We also provided seven CTL-A analogs and elucidated preliminary structure-activity relationships. The in vivo ALI mouse model further suggested that CTL-A alleviated acute lung injury with reductions in lung edema and pathol. deterioration, which is better than sivelestat, one approved elastase inhibitor. The activity of CTL-A against elastase, along with its cellular safety and well-established synthetic route, warrants further investigation of CTL-A as a candidate against COVID-19 pathogeneses.
There is still a lot of research devoted to this compound(SMILES：O=C(OCC)C(CBr)=O)Safety of Ethyl 3-bromo-2-oxopropanoate, and with the development of science, more effects of this compound(70-23-5) can be discovered.
