In this study, a novel series of oxazoline and thiazoline were designed as inhibitors of cytochrome P450 14 alpha-sterol demethylase (CYP51) from Candida albicans and peptide deformylase (PDF) of Escherichia coli. The long chain dibromo derivative of fatty acid esters on reaction with urea and thiourea gave their corresponding oxazolines and thiazolines, respectively. All the compounds were characterized
在这项研究中,设计了一系列新的恶唑啉和噻唑啉作为白色念珠菌的细胞色素P450 14α-甾醇脱甲基酶(CYP51)和大肠杆菌的肽去甲酰基酶(PDF)的抑制剂。脂肪酸酯的长链二溴衍生物与尿素和硫脲反应后,分别得到了相应的恶唑啉和噻唑啉。所有化合物均通过其光谱数据(IR,1 H NMR,13NMR和MS),并通过圆盘扩散测定法测试其抗菌和抗真菌活性,并通过肉汤微稀释法测定其对革兰氏阳性和革兰氏阴性菌以及真菌菌株的最低抑菌浓度。抗菌筛选研究表明,所有化合物均为有效的抗菌剂。通过物质活性谱预测软件计算出化合物的相似药物特性后,Discovery Studio 2.5会计算与ADMET相关的描述符,以预测活性和生物利用度化合物的药代动力学特性。在大肠杆菌PDF和白色念珠菌CYP 450-14DM上进行了分子对接研究了解分子在受体活性位点的结合方式。化合物(2-氨基-5-(羰甲氧基辛基)-1,3-恶唑啉,2-氨基-5-(羧甲氧基辛基)-1

Abstract Bromination of alkenes with sodiumbromide in the presence sodium perborate provides a simple, high yield route to dibromoalkanes.
field at the intersection of mechanical forces and chemical reactions. Herein, we have reported a vicinal dibromination of unsaturated hydrocarbons using piezoelectric material (Li2TiO3) as a redox catalyst. Furthermore, the reaction can be efficiently scaled up to 10 mmol and performed under an air atmosphere at room temperature without solvents or external reductants, and Li2TiO3 can be reused multiple
机械氧化还原化学是机械力和化学反应交叉领域的一个快速发展的领域。在此,我们报道了使用压电材料(Li 2 TiO 3 )作为氧化还原催化剂的不饱和烃的邻位二溴化。此外,该反应可以有效地放大至10mmol,并且在室温下在空气气氛下进行,无需溶剂或外部还原剂,并且Li 2 TiO 3可以多次重复使用而不改变结构。
