A new series of 4-benzyl-6,7,8,9-tetrahydro[1]benzothieno[3,2-e][1,2,4]triazolo[4,3-a]pyrimidines was synthesized motivated by the widely reported anticancer activity of thieno[2,3-d]pyrimidines and triazolothienopyrimidines. The in vitro cytotoxic activity of some selected compounds was evaluated against two human cell lines: prostate cancer (PC-3) and colon cancer (HCT-116). A preliminary study of
Design, synthesis, in vitro and in vivo evaluation of novel pyrrolizine-based compounds with potential activity as cholinesterase inhibitors and anti-Alzheimer's agents
Novel series of pyrrolizine based compounds (4–6 and 9–11) were designed, synthesized and evaluated as potential anti-Alzheimer agents. Most of the tested compounds showed selectivity to hAChE over hBChE and effectively inhibited self–induced amyloid beta aggregation in vitro. Among these derivatives, compound 10 displayed high selectivity towards hAChE (Ki = 1.47 ± 0.63 μM for hAChE and Ki = 40.15 ± 3

This invention is directed to compounds and salts that are generally useful as anthelmintic agents or as intermediates in processes for making anthelmintic agents. This invention also is directed to processes for making the compounds and salts, pharmaceutical compositions and kits comprising the compounds and salts, uses of the compounds and salts to make medicaments, and treatments comprising the administration ofthe compounds and salts to animals in need of the treatments.
Six piperazine derivatives 6a – f containing 1,4-benzodioxan moiety have been synthesized and characterized by 1 H NMR, ESI-MS and elemental analysis. The structure of 6d was further confirmed by single crystal X-ray diffraction. All these novel compounds were screened for their in vivo anti-inflammatory activity employing classical para -xylene-induced mice ear-swelling model. The results revealed
已经合成了六个含有1,4-苯并二恶烷部分的哌嗪衍生物6a – f,并通过1 H NMR,ESI-MS和元素分析对其进行了表征。单晶X射线衍射进一步证实了6d的结构。使用经典的对二甲苯诱导的小鼠耳肿胀模型筛选所有这些新化合物的体内抗炎活性。结果表明,大多数目标化合物均具有显着的抗炎活性,特别是在苯基哌嗪环上具有邻位取代甲氧基的化合物6a表现出最佳的活性。

In this study, certain 3-substituted styrylquinoxalin-2( 1H)-ones (2a-d) and their 2-chloro (3a-d) and 2-piperazinyl derivatives (4a-g) were synthesized from 3-methylquinoxalin-2(lH)-one (1). In addition, a series of l-alkyl-3-substituted styrylquinoxalin-2(1H)-ones (5a-d) was also prepared. Moreover, 3-(N 2 -arylidenehydrazinocarbonyl)quinoxalin-2(1H)-ones (8a-c) as well as their cyclized oxadiazolinyl
