Ethers are a class of organic compounds that contain an ether group—an oxygen atom connected to two alkyl or aryl groups. 73724-45-5, formula is C18H17NO5, Name is Fmoc-Ser-OH.They have the general formula R–O–R′, where R and R′ represent the alkyl or aryl groups. Formula: C18H17NO5.
Wolf, Philipp;Beck-Sickinger, Annette G. research published 《 The ring size of monocyclic ET-1 controls selectivity and signaling efficiency at both endothelin receptor subtypes》, the research content is summarized as follows. Cardiovascular diseases (CVDs) like hypertension are a major cause for death worldwide. In the cardiovascular tissue, the endothelin system-consisting of the receptor subtypes A (ETAR) and B (ETBR) and the mixed agonist endothelin 1 (ET-1)-is a major key player in the regulation of vascular tone and blood pressure. Tight control of this system is required to maintain homeostasis; otherwise, the endothelin system can cause severe CVDs like pulmonary artery hypertension. The high sequence homol. between both receptor subtypes limits the development of novel and selective ligands. Identification of small differences in receptor-ligand interactions and determination of selectivity constraints are crucial to fine-tune ligand properties and subsequent signaling events. Here, we report on novel ET-1 analogs and their detailed pharmacol. characterization. We generated simplified ET-1-derived monocyclic peptides to provide an accessible synthesis route. By detailed in vitro characterization, we demonstrated that both G protein signaling and the subsequent arrestin recruitment of activated ETBR remain intact, whereas activation of the ETAR depends on the intramol. ring size. Increasing of the intramol. ring structure reduces activity at the ETAR and shifts the peptide toward ETBR selectivity. All ET-1 analogs displayed efficient ETBR-mediated signaling by G protein activation and arrestin 3 recruitment. Our study provides in-depth characterization of the ET-1/ETAR and ET-1/ETBR interactions, which has the potential for future development of endothelin-based drugs for CVD treatment. By identification of Lys9 for selective labeling, novel analogs for peptide-mediated shuttling by ET-1 are proposed.
Formula: C18H17NO5, Fmoc-Ser-OH, also known as Fmoc-Ser-OH, is a useful research compound. Its molecular formula is C18H17NO5 and its molecular weight is 327.3 g/mol. The purity is usually 95%.
Fmoc-L-Ser-OH is a synthetic peptide that belongs to the group of glycopeptides. It is used as a model for such compounds and has been shown to have antimicrobial activity in vitro against gram-positive bacteria, especially Staphylococcus epidermidis. This compound was synthesized from 3-mercaptopropionic acid and chloride in the presence of hydroxyl groups and epidermal growth factor. The synthetic pathway can be divided into three steps: (1) condensation of 3-mercaptopropionic acid with hydrochloric acid to yield 3-mercaptoacrylic acid; (2) esterification of 3-mercaptoacrylic acid with glycine to form Fmoc-L-Ser; and (3) deprotection of Fmoc protecting group., 73724-45-5.
