2-[5-(Pyridin-2-yl)-4H-1,2,4-triazol-3-yl]sulfanyl}acetic acid (H2L) with manganese(II), zinc(II) and cadmium(II) acetate in CH3OH/H2O mixture result in the corresponding metal complexes. All the obtained complexes were characterized by IR spectroscopy, elemental analyses, ESI-MS, and single-crystal X-ray diffraction. Structural analyses reveal the dinuclear complexes with the compositions [Mn2L2(CH3OH)2(H2O)2]·2CH3OH
摘要 2-[5-(吡啶-2-基)-4H-1,2,4-三唑-3-基]硫烷基}乙酸( H 2 L )与锰(II)、锌(II)和CH 3 OH/H 2 O 混合物中的乙酸镉 (II)生成相应的金属络合物。所有获得的配合物均通过红外光谱、元素分析、ESI-MS 和单晶 X 射线衍射表征。结构分析表明双核配合物的组成为[Mn 2 L 2 (CH 3 OH) 2 (H 2 O) 2 ]·2CH 3 OH ( 1 ), [Zn 2 L 2 (CH 3 OH)2 (H 2 O) 2 ]·2CH 3 OH ( 2 ) 和一维链结构 [CdL(H 2 O)] n ( 3 ) 在所有配合物中,H 2 L被双重去质子化 (L 2- ) 并用作平衡阴离子。羧酸盐在1和2 中充当单齿配体,而在3 中充当μ 1,1 -桥连配体。杰克豆脲酶抑制活性的测定表明,1和3对杰克豆脲酶具有相当大的抑制作用,IC50值分别为 12
Not Every Hit‐Identification Technique Works on 1‐Deoxy‐d‐Xylulose 5‐Phosphate Synthase (DXPS): Making the Most of a Virtual Screening Campaign
Hitidentification in drug discovery is not always straightforward: A virtualscreening against Mycobacterium tuberculosis 1-deoxy-d-xylulose 5-phosphate synthase (DXPS) did not result in a suitable on-target hit, but testing against pathogenic bacteria revealed promising growth inhibition of Gram-negative Escherichia coli of one compound class. Establishing a robust synthetic route made quick investigation
