Electrophysiology of Epithelial Sodium Channel (ENaC) Embedded in Supported Lipid Bilayer Using a Single Nanopore Chip
Nanopore-based technologies
are highly adaptable supports for developing
label-free sensor chips to characterize lipid bilayers, membrane proteins,
and nucleotides. We utilized a single nanopore chip to study the electrophysiology
of the epithelial Na<sup>+</sup> channel (ENaC) incorporated in supported
lipid membrane (SLM). An isolated nanopore was developed inside the
silicon cavity followed by fusing large unilamellar vesicles (LUVs)
of DPPS (1,2-dipalmitoyl-<i>sn</i>-glycero-3-phosphoserine)
and DPPE (1,2-dipalmitoyl-<i>sn</i>-glycero-3-phosphoethanolamine)
to produce a solvent-free SLM with giga-ohm (GΩ) sealed impedance.
The presence and thickness of SLM on the nanopore chip were confirmed
using atomic force spectroscopy. The functionality of SLM with and
without ENaC was verified in terms of electrical impedance and capacitance
by sweeping the frequency from 0.01 Hz to 100 kHz using electrochemical
impedance spectroscopy. The nanopore chip exhibits long-term stability
for the lipid bilayer before (144 h) and after (16 h) incorporation
of ENaC. Amiloride, an inhibitor of ENaC, was utilized at different
concentrations to test the integrity of fused ENaC in the lipid bilayer
supported on a single nanopore chip. The developed model presents
excellent electrical properties and improved mechanical stability
of SLM, making this technology a reliable platform to study ion channel

Synthesis, structure elucidation, SC-XRD/DFT, molecular modelling simulations and DNA binding studies of 3,5-diphenyl-4,5-dihydro-1<i>H</i>-pyrazole chalcones
Deoxyribonucleic acid (DNA) acts as the most important intracellular target for various drugs. Exploring the DNA binding interactions of small bioactive molecules offers a structural guideline for designing new drugs with higher clinical efficacy and enhanced selectivity. This study presents the facile synthesis of pyrazoline-derived compounds (4a)-(4f) by reacting substituted chalcones with hydrazine hydrate using formic acid. The structure elucidation of substituted pyrazoline compounds was carried out using 1H-NMR, FT-IR and elemental analyses. While the crystal structures of two compounds (4a) and (4b) have been resolved by single-crystal X-ray diffraction (SC-XRD) analysis. Hirshfeld surface analysis also endorsed their greater molecular stability. Computational calculations at DFT/B3LYP/6-311++G(d,p) were executed to compare the structural properties (bond angle and bond length) and explore reactivity descriptors, frontier molecular orbitals (FMO), Mulliken atomic charges (MAC), molecular electrostatic potential (MEP) and electronic properties. All the compounds were evaluated for DNA binding interactions by UV-Vis spectrophotometric analysis. The results revealed that compounds (4a)-(4f) bind to DNA via non-covalent binding mode having binding constant values ranging from 1.22 × 103 to 6.81 × 104 M−1. The negative values of Gibbs free energy also proved the interaction of studied compounds with DNA as a spontaneous process. The findings of molecular docking simulations depicted that these studied compounds showed significant binding interactions with DNA and these results were consistent with experimental findings. Compound (4b) was concluded as the most potent compound of the series with the highest binding constant (4.95 × 104) and strongest binding affinity (-8.48 kcal/mol). Communicated by Ramaswamy H.
