Employing a synergistic combination of theoretical density functional theory (DFT) and experimental techniques, we conducted a comprehensive analysis elucidating the structural and pharmacological attributes of 5-(adamantan-1-yl)-4-butyl-2,4-dihydro-3-1,2,4-triazole-3-thione (5A4BT) as a potent COX inhibitor. The X-ray crystallographic data of 5A4BT showed the pivotal role played by weak interactions, notably π-π and C-H-π interactions, alongside hydrogen bonding, in orchestrating the intricate supramolecular architectures within the crystalline lattice. A quantitative analysis of the arrangement of the crystal structure, as well as both inter- and intramolecular interactions, was conducted using Hirshfeld surfaces and 2D fingerprint plots.

Microbial fuel cells have emerged as a technique that can effectively treat wastewater with simultaneous electricity generation. The present study explored the performance of microbial fuel cell for decolorizing and degradation of azo dyes including, remazol brilliant blue (RBB), mordant blue 9 (MB9), acid red1 (AR1), and orange G (OG), while, simultaneously generating electricity. Wheat straw and its hydrolysate was used as a potential substrate in MFC.

Microbial fuel cell is one of the most convenient and cost-effective technology for producing the clean energy. This study explores the exoelectrogenic behavior of Pichia fermentans in a microbial fuel cell. Two different reactor designs (double- and single-chambered) were tested in the presence and in the absence of a mediator (methylene blue).

Selective lignin degrading white rot fungi viz. Phanerochaete chrysosporium, Phlebia brevispora, and Phlebia floridensis were selected to evaluate antioxidant potential and auxin (indole acetic acid) production in complex and synthetic medium. Antioxidant potential of these fungi was tested against different free radicals including 2, 2-diphenyl-1-picrylhydrazyl (DPPH), nitric oxide, ferrous ion, and ferric ion along with total phenolic content.

This study demonstrated the protective efficiency of extracts of the Indian variety of Ophiocordyceps sinensis (=Cordyceps sinensis) (CSEs) in HT22 (murine hippocampal) cells under hypoxic conditions. Various parameters such as cell viability, reactive oxygen species, levels of endogenous antioxidants, inflammatory cytokines, transcription factors, and oxidation of macromolecules were analyzed. In addition, the radical scavenging abilities of hydroxyl radicals, nitric oxide, and superoxide radicals were also studied.

In the present study, we aimed to elucidate the antioxidant property and anti-inflammatory activity of the aqueous extract of the Indian species of Ophiocordyceps sinensis (AECS), which demonstrates medicinal activity against numerous diseases. The chemical composition of AECS was quantified using a colorimeteric technique to determine the total phenolic and flavonoid contents. Antioxidant activity was determined by assays for 2,2'-azinobis(3-ethylbenzothiazoline-6-sulphonic acid)diammonium salt (ABTS); 2,2-diphenyl-1-picryl-hydrazyl (DPPH); and ferric reducing antioxidant power (FRAP).
