In this study, a series of twenty-five ring-substituted 4-arylamino-7-chloroquinolinium chlorides were prepared and characterized. The compounds were tested for their activity related to inhibition of photosynthetic electron transport (PET) in spinach (Spinacia oleracea L.) chloroplasts and also primary in vitro screening of the synthesized compounds was performed against mycobacterial species. 4-
在本研究中,制备并表征了一系列二十五个环取代的 4-芳基氨基-7-氯喹啉氯化物。测试了这些化合物与抑制菠菜 (Spinacia oleracea L.) 叶绿体中光合电子传递 (PET) 相关的活性,并且还针对分枝杆菌物种对合成的化合物进行了初步体外筛选。4-[(2-Bromophenyl)amino]-7-chloroquinolinium chloride 对 M. marinum、M. kansasii、M. smegmatis 和 7-chloro-4-[(2-methylphenyl)amino]quinolinium chloride 显示出高生物活性对耻垢分枝杆菌和鸟分枝杆菌亚种的生物活性。副结核病。最有效的化合物表现出相当低的毒性(LD₅₀ > 20 μmol/L) 在初步体外细胞毒性筛选中针对人单核细胞白血病 THP-1 细胞系。发现测试的化合物在光系统 II 中抑制 P

class of nonimidazolehistamineH(3) receptor ligands were developed that simultaneously possess strong inhibitory activity on the main histamine metabolizing enzyme, histamine N-methyltransferase (HMT). The novel compounds contain an aminoquinoline moiety, which is an important structural feature for HMT inhibitory activity, connected by different spacers to a piperidino group (for H(3) receptor antagonism)
