N-Cycloamino substituent effects on the packing architecture of ortho-sulfanilamide molecular crystals and their in silico carbonic anhydrase II and IX inhibitory activities
摘要:
为了寻找具有治疗特性的新型 "磺胺药物",我们合成了邻硝基磺酰胺和 N-环氨基邻磺酰苯胺,并利用 1H NMR、13C NMR 和 FT-IR 光谱以及单晶 X 射线衍射(SC-XRD)等技术对其进行了表征。计算得出的密度泛函理论(DFT)优化的分子几何形状与 SC-XRD 得到的构象相似。N-piperidinyl-o-sulfanilamide 和 N-indolinyl-o-sulfanilamide 的分子对接支持了邻磺酰胺能够与人类碳酸酐酶 II 和 IX 抑制剂(hCA II 和 IX;PDB 条目 4iwz 和 5fl4)结合的观点。对三种邻硝基磺酰胺{1-[(2-硝基苯基)磺酰基]吡咯烷,C10H12N2O4S,1,1-[(2-硝基苯基)磺酰基]哌啶、1-[(2-硝基苯基)磺酰基]吡咯烷,C10H12N2O4S,1;1-[(2-硝基苯基)磺酰基]哌啶,C11H14N2O4S,2;和 1-[(2-硝基苯基)磺酰基]-2,3-二氢-1H-吲哚,C14H12N2O4S,3}以及三种 N-环氨基邻磺酰苯胺[2-(吡咯烷-1-磺酰基)苯胺,C10H14N2O2S,4、2-(哌啶-1-磺酰基)苯胺,C11H16N2O2S,5 和 2-(2,3-二氢-1H-吲哚-1-磺酰基)苯胺,C14H14N2O2S,6]表明,氢键和 π-π 相互作用等力将分子连接在一起,并进一步表明,电荷转移可促进生物活性以及在哌啶基和苯基上形成生物相互作用的能力。
