Vibrational spectroscopic studies, Fukui functions, HOMO-LUMO, NLO, NBO analysis and molecular docking study of (E)-1-(1,3-benzodioxol-5-yl)-4,4-dimethylpent-1-en-3-one, a potential precursor to bioactive agents

The FT-IR and FT-Raman spectra of (E)-1-(1,3-benzodioxol-5-yl)-4,4-dimethylpent-1-en-3-one were recorded and analyzed experimentally and theoretically. The observed experimental and theoretical wavenumbers were assigned using potential energy distribution. The NLO properties were evaluated by the determination of first and second hyperpolarizabilities of the title compound. From the frontier molecular orbital study, the HOMO centers over the entire molecule except the methyl groups, while the LUMO is over the entire molecule except the CH2 group with the dioxole ring and one of the methyl groups. From the MEP plot, it is evident that the negative region covers the carbonyl and [Formula presented] groups and the positive region is over CH2 groups. The Fukui functions are also reported. The calculated geometrical parameters are in agreement with the XRD results. From the molecular docking study, the docked ligand title compound forms a stable complex with the androgen receptor and gives a binding affinity value of??8.1?kcal/mol and the results suggest that the compound might exhibit inhibitory activity against androgen receptor.

Epilepsy affects approximately 50 million individual worldwide but only 70% thereof are adequately controlled by the clinically used antiepileptic agents. The chemical structure of stiripentol (STP) is significantly different from any other marketed antiepileptic drug and it is approved as an add-on medication to control the childhood epilepsy. Detailed vibrational spectroscopic features of stiripentol aided by density functional theory (DFT) computations have been explored in the current study. Furthermore, the frontier molecular orbital (FMO) analysis, distribution of electric charges on the STP molecule and natural bond orbital (NBO) analysis were investigated using DFT computations. Also, Hirshfeld surface maps of STP and its 2D fingerprint plots were studied to gain insight into different patterns of its intermolecular interactions. Moreover, molecular docking simulations were conducted to manifest the probable binding pose of stiripentol to an anticonvulsant target protein.

A series of stiripentol (STP) analogues namely, 2-[(1E)-1-(1,3-benzodioxol- 5-yl)-4,4-dimethylpent-1-en-3-ylidene]-N-(aryl/H)hydrazinecarboxamides 7a-h, (±)-(5RS)-N-(aryl/H)-(1,3-benzodioxol-5-yl)-3-tert-butyl-4, 5-dihydro-1H-pyrazole-1-carboxamides (±)-8a-h, and (±)-[(5RS)-(1, 3-benzodioxol-5-yl)-3-tert-butyl-4,5-dihydro-1H-pyrazol-1-yl](aryl)methanones (±)-13a-f was synthesized by adopting appropriate synthetic routes and was pharmacologically evaluated in the preliminary anticonvulsant screens. The selected bioactive new chemical entities were subjected to ED50 determination and neurotoxicity evaluation. The most active congeners are 7h in MES screen and (±)-13b in scPTZ screen which displayed ED50 values of 87 and 110 mg/kg, respectively, as compared to that of STP (ED 50 = 277.7 and 115 mg/kg in MES and scPTZ, respectively).

The Wittig-Horner and Claisen-Schmidt syntheses of acyclic α-enanes bearing a 2-furyl or 3,4-methylenedioxyphenyl group in the β-position have been achieved using activated barium hydroxide C-200 with good yields.The Wittig-Horner reaction in homogeneous phase is shown to be more efficient than the Claisen-Schmidt condensation under interfacial solid-liquid conditions.The 1H and the 13C megnetic parameters of compounds 5 and 6 are described.The use of 1H-13C correlation spectra helped in the unambiguous assignment of the olefinic and aromatic carbons of α-enones 5a and 6a.
