摘要
Polycyclic aromatic compounds encompass a diverse array of molecules that exhibit remarkable chemical activity and play pivotal roles across various scientific domains. Coumarins represent a diverse class of heterocyclic compounds, which exhibit a wide range of significant biological and pharmacological activities, while containing at least two aromatic rings in their structure. Because chemical, biological, as well as pharmacological properties and activities are highly dependent on the structural characteristics of the molecule, in this paper a detailed structural investigation of the monocrystal structure of newly synthesized (E)-N ' -(1-(2,4-dioxochroman-3-ylidene)ethyl)-3,4,5-trimethoxybenzohydrazide was performed. The DFT model that is best suited for describing the structural parameters of coumarin-benzohydrazides was determined. Out of three tested models which were previously proven to be excellent in describing structures of organic compounds, B3LYP-D3BJ was found to be the best in describing the structure of investigated coumarin derivative in regard to the obtained X-ray and spectroscopic data. Determination of the best theoretical model allows for better structural characterization of the coumarin-benzohydrazides for which monocrystals and consequently X-ray structure cannot be obtained. Finally, both experimental and computational analysis indicated (with high mutual correlation) that investigated compound showed excellent binding potential toward the albumin, indicating good distribution through the organism.
