two partners for halogen bond interactions: the backbone carbonyl oxygen atoms of E493 and T497. Additionally, compounds with heavier halogen atoms were found to bind with the SERT via a distinctly different binding mode, a result not presented elsewhere. The subsequent analysis of the prepared XSAR sets showed that E493 and T497 participated in the largest number of formed halogen bonds. The XSAR library
作用于血清素转运蛋白 (SERT) 的选择性血清素再摄取抑制剂 (SSRI) 是处方最广泛的抗抑郁药物之一。所有五种获批的 SSRI 都含有氟或氯原子,并且描述它们与较重卤素(即溴和碘)类似物的报告数量有限。为了阐明卤素原子在 SSRIs 与 SERT 结合中的作用,我们设计了一系列 22 种氟西汀和氟伏沙明类似物,它们被氟、氯、溴和碘原子取代,它们在苯环上的排列不同。获得的生物活性数据,得到了全面的计算机支持结合模式分析,允许识别卤素键相互作用的两个伙伴:E493 和 T497 的骨架羰基氧原子。此外,发现具有较重卤素原子的化合物通过明显不同的结合模式与 SERT 结合,这一结果未在别处介绍。对制备的 XSAR 集的后续分析表明,E493 和 T497 参与形成的卤键数量最多。XSAR 库分析导致合成了两种最活跃的化合物(3,4-diCl-氟西汀42、SERT K i = 5 nM 和 3

A novel class of molecules with structure N‐(3‐arylpropyl)‐9,10‐dihydro‐9‐oxoacridine‐4‐carboxamides (20–29) were designed by generating a pharmacophore for potent MDR reversal activity using phase drug design software. The designed molecules were synthesized by a novelsynthesis route and evaluated for their inhibitory effects on the transport activity of P‐glycoprotein (P‐gp) by standard Hoechst

The present invention provides isolated N-methyl-3-(3-methylphenoxy)-3-phenylpropylamine hydrochloride, and preparation thereof as well as of N-methyl-3-(4-methylphenoxy)-3-phenylpropylamine hydrochloride and of N-methyl-3-phenoxy-3-phenylpropylamine hydrochloride. The invention further provides the use of the above compounds as reference markers and/or reference standards during the synthesis of Atomoxetine. Also provided is a method of limiting the amounts of the impurities 3FT (3-fluorotoluene), 4FT (4-fluorotoluene), and FB (fluorobenzene) in the 2-fluorotoluene starting material used in the synthesis of Atomoxetine Hydrochloride. The purity of the Atomoxetine Hydrochloride product is ensured by determining the amounts of 3FT, 4FT, and FB in the 2-fluorotoluene starting material with the marker 3-ATM HCl.
