Virtual screening of the ChemDiversity and ChemBridge compound databases against dynamin I (dynI) GTPase activity identified 2,5-bis-(benzylamino)-1,4-benzoquinone 1 as a 273 ± 106 μM inhibitor. In silico lead optimization and focused library-led synthesis resulted in the development of four discrete benzoquinone/naphthoquinone based compound libraries comprising 54 compounds in total. Sixteen analogues
针对dynamin I(dynI)GTPase活性对ChemDiversity和ChemBridge化合物数据库进行的虚拟筛选确定了2,5-双-(苄氨基)-1,4-苯醌1为273±106μM抑制剂。在计算机上进行了铅优化和以库为主导的合成,开发了四个基于苯醌/萘醌的化合物库,总共包含54种化合物。16种类似物比铅1更有效,其中2,5-双-(4-羟基苯胺基)-1,4-苯醌(45)和2,5-双(4-羧基苯胺基)-1,4-苯醌(49) IC 50最活跃值分别为11.1±3.6和10.6±1.6μM。分子建模表明,dynI GTP结合位点内49个分子的稳定化涉及许多氢键和疏水相互作用。评价了六个活性最高的抑制剂对网格蛋白介导的内吞作用(CME)的潜在抑制作用。醌45是最有效的CME抑制剂,IC 50(CME)为36±16μM。

Certain aziridin-1-yl-quinones are converted by the action of sodium iodide and aluminium halides into 2-halogenoethylamino-quinones. The behaviour of the latter on catalytic reduction has been studied. The reaction of 3,6-diaziridin-1-yl-p-xyloquinone with concentrated sulphuric acid is reported.
