Synthesis and antitrichinellosis activity of some bis(benzimidazol-2-yl)amines
摘要:
Novel bis(benzimidazol-2-yl)a mines were synthesized using two methods and studied for antitrichinellosis activity. DFT calculations were performed in order to determine the geometry of molecules. All derivatives of 2-aminobenzimidazole exhibited higher activity in vitro against Trichinella spiralis larvae in regard to the activity of albendazole, moreover compounds 4f-i manifested antitrichinellosis effect, which surpassed five times the activity of albendazole. The in vivo screening of intestinal phase of the T spiralis revealed 100% effectiveness of compounds 4g-i at oral dosages of 50 and 100 mg/kg mw, while albendazole possesses 100% efficacy only at a dose of 100 mg/kg mw.

某些新的含苯并咪唑环的噻吩并[2,3 - d ]嘧啶-4(3H)-的合成,抗旋毛虫病和抗原生动物活性
摘要:
合成了一些新颖的噻吩并[2,3 - d ]嘧啶-4(3H)-在嘧啶环的第二个位置上含有苯并咪唑-2-基-硫乙基和苯并咪唑-2-基-甲硫基乙基部分。抗旋毛虫病和抗原生动物作用。化合物的结构通过IR,1 H NMR和元素分析确认。 抗寄生虫药筛选显示,噻吩并[2,3 - d ]嘧啶-4(3H)-的苯并咪唑衍生物在体外对旋毛虫的活性高于阿苯达唑。活性最高的化合物2- [2-(2-(5-硝基-1H-苯并咪唑-1-基)乙基] -5,6,7,8-四氢[1]苯并噻吩并[2,3 - d ]嘧啶-4( 3H)-一22在24 h后以5 mg / kg mw的剂量显示95%的活性,而以相同剂量施用的化合物8和10在48 h后显示90%的功效。化合物2- {2-[((5(6)-硝基-1H-苯并咪唑-2-基)硫代]乙基] -5,6,7,8-四氢[1]-苯并噻吩并[2,3- d ]嘧啶4(3H)-一11在24小时后显示90%的功效。
