Synthesis and evaluation of molecular structure from torsional scans, study of molecular characteristics using spectroscopic and DFT methods of some thiosemicarbazones, and investigation of their anticancer activity
rotating bonds were made to get approximate dihedral angles. UV–Vis spectra were measured for APHT and 2-((2-aminopyridin-3-yl) methylene)-N-methylhydrazinecarbothioamide (APMHT). Their anticancer activity was determined experimentally, for human carcinoma cell lines pertaining to liver, colorectal, and lung. For both APHT and APMHT, frontier molecular orbital parameters, NLO behaviour, and NBO characteristics
尝试合成2-((2-氨基吡啶-3-基)亚甲基)肼基甲硫基酰胺(APHT)。使用元素分析和NMR光谱确定其形成。对其所有五个旋转键的扭转势能扫描进行扫描,以获得近似的二面角。测量了APHT和2-((2-氨基吡啶-3-基)亚甲基)-N-甲基肼甲硫代酰胺(APMHT)的UV-Vis光谱。他们的抗癌活性是通过实验确定的,涉及与肝,结直肠和肺有关的人类癌细胞系。对于APHT和APMHT,都使用DFT / B3LYP / 6-311 ++ G(d,p)的理论水平确定了前沿分子轨道参数,NLO行为和NBO特性。TD-DFT来计算的吸收最大值(λ最大)在DMSO- d 6溶剂中两个分子的电子跃迁。前沿分子轨道用于了解UV-Vis光谱的起源和这两种分子的化学反应性。在测量和计算的结构参数之间发现了很好的一致性。实验和理论UV-Vis光谱也是如此。计算结果表明,这两种分子均适用于NLO应用,这一点已通过NBO
