Simple alcohols are found widely in nature. Ethanol is the most prominent because it is the product of fermentation, a major energy-producing pathway. 141699-55-0, formula is C8H15NO3, Other simple alcohols, chiefly fusel alcohols, are formed in only trace amounts. More complex alcohols however are pervasive, as manifested in sugars, some amino acids, and fatty acids. , Category: alcohols-buliding-blocks
Bai, Chengfeng;Wu, Shuangjie;Ren, Shengnan;Zhu, Meiqi;Luo, Guoshun;Xiang, Hua research published 《 Benzothiophene derivatives as selective estrogen receptor covalent antagonists: Design, synthesis and anti-ERα activities》, the research content is summarized as follows. Estrogen receptor α emerged as a well validated therapeutic target of breast cancer for decades. However, approx. 50% of patients who initially respond to the standard-of-care (SoC), such as undergo therapy of Tamoxifen, generally inevitably progress to an endocrine-resistance ER+ phenotype. Recently, selective estrogen receptor covalent antagonists (SERCAs) targeted to ERα have demonstrated potential as therapeutic alternatives. In the present study, a series of novel 6-OH-benzothiophene (BT) derivatives targeting ERα and derived from Raloxifene were designed, synthesized, and biol. evaluated as covalent antagonists. Driven by the antiproliferative efficacy in ER+ breast cancer cells, chem. optimization finally led to compound I having potent antagonistic activity in ER+ tumor cells while not showing agonistic activity in endometrial cells. Moreover, a docking simulation was carried out to elucidate the binding mode, revealing I as an antagonist and covalently binding to the cysteine residue at the 530 position of ER helix H11.
141699-55-0, Tert-butyl 3-hydroxyazetidine-1-carboxylate is a useful research compound. Its molecular formula is C8H15NO3 and its molecular weight is 173.21 g/mol. The purity is usually 95%.
Tert-butyl 3-hydroxyazetidine-1-carboxylate has been shown to be a good substrate for the preparation of N-protected amino alcohols and amines by the process of reductive amination. In this synthesis, tert-butyl azetidinium chloride is used as a catalyst in the reaction with sodium hydroxide. The tert-butyl group can be removed using ammonium hydroxide in the presence of a base such as triethylamine. This reaction can be performed on a large scale, making it useful in the manufacture of pharmaceuticals. The efficiency and solubility of this process make it suitable for use as an introduction to other processes involving N-protected amino alcohols or amines., Category: alcohols-buliding-blocks
