The current therapeutic approaches are insufficient and primarily focus on alternative symptoms rather than disease modification. Acetylcholinesterase (AChE) inhibitors are a class of drugs that have shown promise in alleviating the cognitive symptoms of AD by preventing the breakdown of acetylcholine, thereby enhancing cholinergic transmission. This study presents the design, synthesis, and assessment of ten novel naphthalene-pyrazoline derivatives as AChE inhibitors. Each compound was synthesized using a rational drug design approach, targeting key structural features necessary for effective AChE inhibition. The inhibitory activities of the synthesized compounds were assessed by <em>in vitro</em> study where out of all compounds <strong>AJ-a</strong> showed potency with IC<sub>50</sub> value of 56.15 ± 1.84 μM. The <em>in vivo</em> studies were also performed using zebrafish model, behavior parameters such as T-maze and Novel diving test. Molecular docking studies were performed to analyse the binding interactions between the inhibitors and the active site of AChE. The docking results provided insights into the key binding interactions and conformations contributing to the inhibitory activity.

Considering the presence of a mixture of metal oxides in low-cost bauxite ore, its catalytic activity towards the quality and quantity of PO and the composition of syngas has been explored experimentally. A positive selectivity towards the reduced temperature (about 10 °C) degradation of PPW with catalysts has been identified during the thermogravimetric (TGA) study. A batch reactor study was conducted with PPW with varied proportions of catalyst, temperatures (525 °C–600 °C), and heating rates (5, 10, and 15 °C/min) to quantify the effects of process conditions on end products’ characteristics and to identify the optimal process parameters. The pyrolysis temperature of 575 °C at 15 °C/min with 10 % catalyst produced the superior quality PO. The corresponding yields of PO and gaseous products were 75.14 % and 17.16 %, respectively. The analysis of PO by FTIR and GC-MS showed higher concentrations of lighter hydrocarbons suitable for gasoline range fuel, namely 2, 4-dimethyl heptane, 2, 6-dimethyl-nonane, and 2, 4-dimethyl-1-heptene, in addition to aromatics. The GC test of gaseous products showed that the presence of bauxite ore significantly enhanced the hydrogen recovery in gaseous products compared to thermal pyrolysis alone. Under optimum conditions, the hydrogen content in the gaseous product reached up to 9.8 %, fulfilling the primary aim of the study.

The details of gas adsorption were examined through the density functional theory (DFT) approach at the M08HX/LanL2DZ level of theory. The energy gap was reduced upon adsorption, with the <strong>PSB1</strong> complex attributed with the least energy of 3.677 eV, and the greatest energy gap of 4.491 eV to the <strong>PB1</strong> complex. Again, the highest perturbation energy of 382.42 kcal/mol for the <strong>PSB1</strong> complex and a relatively high energy of 229.81 kcal/mol for <strong>PTB1</strong> indicate that these surfaces are more stabilized upon adsorption. In most cases, chemisorption phenomena of adsorption were observed, with the adsorption energy values within a relatively small range of −0.8042 to −0.9459 eV. Hence, this study gives a conclusive scientific report that Bi@SiCNT, Se–Bi@SiCNT, and Te–Bi@SiCNT surfaces are potential candidates for coupling future working sensor devices for PDBE.</div></div>","PeriodicalId":17276,"journal":{"name":"Journal of the Indian Chemical Society","volume":"102 7","pages":"Article 101800"},"PeriodicalIF":3.2,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144170125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
