“…The basis set 6-311G(d,p) augmented by "d" polarization function on heavy atom and "p" polarization function on hydrogen atoms were used for better description of polar bonds of molecules [14,15]. The UV-vis spectrum, electronic transitions, vertical excitation energies and oscillator strength were computed with time dependent DFT (TD-DFT) method [16,17].…”

In this work an attempt is made to analysis of the possible different conformers of p-coumaric acid (PCA) by using density functional method. The total energy of four possible conformers were calculated by using B3LYP/6-311G(d,p) method. Computational result identifies that the most stable conformer of PCA is C2. The formation of inter-and intra-molecular hydrogen bonding between -OH and -COOH group gave the evidence for dimer formation for PCA molecule. The highest occupied-lowest unoccupied molecular orbital analysis shows that the negative electrostatic region situated over the -COOH group and positive electrostatic potential region are localized on ring system and all hydrogen. The PCA has been screened to anti-microbial activity and found to exhibit antibacterial effects. Molecular docking results suggest that PCA may exhibit inhibitory activity against lung cancer protein and may act as potential against lung cancer.

New metalloporphyrazines (MgPz, ZnPz) containing peripheral tetrasubstitutions derived from 7,8dihydro6H,14H,19Hdibenzo[bj] [1,12,5,8]dioxadithiacyclopentadecine16,17dicarbonitrile (6) have been synthesized by a multistep reaction sequence and characterized. Compound 6 has been prepared by the reaction of 1,3di(2bromomethyl phenoxy) propane (3) or 1,3di(2iodomethylphenoxy) propane (4) which were prepared via bromination or iodination of {2[3(2hydroxymethylphenoxy) propoxy]phenyl} methanol (2) and cis1,2dicyano1,2ethylenedithiolate (5). The novel magnesium porphyrazine was prepared by the cyclotetramerization reaction of 6 with magnesium butoxide. The onestep synthesis of porphyrazinato zinc complex has been achieved without a reaction sequence by using dicyano compound (6) and zinc butoxide. The prediction of the geometry optimization, normal mode frequencies, 1 H, 13 C NMR, UV absorption spectra, chemical shifts, electronic properties and NBO analysis of the compound were examined by using B3LYP method with a 631G(d, p) basis set. These novel compounds were characterized by a combination of elemental analysis, 1 H, 13 C NMR, FTIR, UVvis and MS spectral data. An Xray crystal structure of dicarbodinitrile compound (6) was also investigated.
