Solid Nano dispersions were developed using the \"Box-Behnken Design\" and emulsion solvent evaporation procedure to improve the solubility and bioavailability. Streptozotocin (SPZ) and Nicotinamide (NA) caused diabetes in Wistar rats. DN developed 30-45 days after disease induction. All rat groups underwent histological, biochemical and pharmacokinetic evaluation. The optimized batch of Cilostazol Loaded Novel Curcumin Tagged Solid Nanodispersion (CLT-15 SND) estimated renal, lipid, and cytokine profiles better than the conventional batch. CLT-15 SND, given orally to diabetic rats for 45 days, significantly lowered fasting BGL and IL-6 levels and improved lipid and kidney-profile markers and body weight compared to plain Cilostazol Loaded Solid Nanodispersion (CLT-15 WC SND). CLT-15 SND treatment groups showed decreased blood glucose by 3.38 and 9.71 percent, increased body weight by 2.81 and 5.27 percent, improved Interleukin-6 (IL-6) by 21.36 and 18.36 percent, improved urine albumin levels by 5.67 and 14.19 percent and creatinine levels by 3.125 and 37.5 percent, improved serum urea by 30.48 percent, increased serum albumin by 2.59 and 11.18 percent, and decreased creatinine and 5.03 and 8.12 percent, respectively as compared to CLT-15 WC and MP treatment animal groups.

Despite extensive research, effective treatments addressing the multifaceted pathophysiology of AD remain elusive. This study investigates the therapeutic potential of twenty-seven prolinamides (P1 - P27), with the focus on their interactions with key proteins implicated in AD pathogenesis. Four of the compounds, namely; 10-((4-nitrophenyl)prolyl)-10 H-phenothiazine (P14), 2-((4-nitrophenyl)prolyl)isoindoline (P19), 1-(4-formylphenyl)-<i>N</i>-(p-tolyl)pyrrolidine-2-carboxamide (P22), and <i>N</i>,1-bis(4-nitrophenyl)pyrrolidine-2-carboxamide (P27) showed promising potential as Alzheimer's drug. In-silico approaches including molecular docking, molecular dynamic (MD) simulation, post md study, physicochemical and drug-likeness parameters were employed to ascertain the potential of these compounds as inhibitors of certain proteins implicated in the pathophysiology of Alzheimer's disease. Molecular docking and dynamics simulations demonstrated that P14, P19, P22 and P27 exhibited promising binding affinities towards crucial AD-associated proteins, including Beta-Secretase 1 (BACE1), Butyrylcholinesterase (BuChE), and Tau-tubulin kinase 2 (TTBK2). Structural stability analyses revealed that prolinamides, particularly P22 and P27 for BACE1 and P14 and P19 for BuChE, exhibited greater stability than their reference ligands, indicated by lower RMSD, RoG, and RMSF values. For BuChE, Rivastigmine had a docking score of -7.0 kcal/mol, a binding free energy (ΔG_bind) of -22.19 ± 2.44 kcal/mol, RMSD of 1.361 ± 0.162 Å, RMSF of 9.357 ± 3.212 Å, and RoG of 22.919 ± 0.064 Å, whereas P19 exhibited a superior docking score of -10.3 kcal/mol, a significantly better ΔG_bind of -33.74 ± 2.84 kcal/mol, RMSD of 1.347 ± 0.132 Å, RMSF of 8.164 ± 2.748 Å, and RoG of 22.868 ± 0.070 Å. Physicochemical and pharmacokinetic assessments affirmed the drug-likeness and bioavailability of P19 notably capable of penetrating the blood-brain barrier. Compounds P19 and P22, emerged as multi-targeted ligands, offering the potential for simultaneous modulation of multiple AD-related pathways. These findings highlight the possibilities of these compounds to be explored as novel therapeutic agents for AD. They also highlight the need for further experimental validation to confirm their efficacy and safety profiles, advancing them toward clinical application in AD management.</p><p><strong>Graphical abstract: </strong></p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s40203-024-00250-z.</p>","PeriodicalId":94038,"journal":{"name":"In silico pharmacology","volume":"12 2","pages":"80"},"PeriodicalIF":0.0,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11365881/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142121435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated the in vitro antibacterial activity of 16 flavonoids against bovine mastitis pathogens. Two flavones: 2-(4-methoxyphenyl)chromen-4-one (<b>1</b>) and 2-(3-hydroxyphenyl)chromen-4-one (<b>4</b>) showed inhibition of the growth of <i>Klebsiella oxytoca</i> with MIC values range (25-50 µg mL^- 1) followed by a structure-activity relationship (SAR) study indicating that the presence of a hydroxyl group at C-3` or methoxy at C-4` increases the activity against <i>Klebsiella oxytoca</i> while the presence of hydroxyl group at C-7 decreases the activity. Furthermore, a structure-based drug development approach was applied using several in silico tools to understand the interactions of active flavones at the active site of the DNA gyrase protein. Compound (<b>4</b>) showed a higher docking score than quercetin (standard) which is known to have antibacterial activity by inhibiting the DNA gyrase. In addition, the structure-based pharmacophores of compound (<b>4</b>) and quercetin showed similar pharmacophoric features and interactions with DNA gyrase.

This study investigated the antiviral potential of balsaminol, a bioactive compound from <i>Momordica balsamina</i>, and its inhibitory activities against SARS-CoV-2 receptor proteins. In this study, three Food and Drug Administration (FDA) COVID-19 approved drugs namely; nirmatrelvir, ritonavir and remdesivir were used as positive control. Molecular docking was performed to determine the predominant binding mode (most negative Gibbs free energy of binding/ΔG) and inhibitory activity of balsaminol against SARS-CoV-2 receptor proteins. The pharmacokinetics, toxicity, physicochemical and drug-like properties of balsaminol were evaluated to determine its potential as an active oral drug candidate as well as its non-toxicity in humans. The results show that balsaminol E has the highest binding affinity to the SARS CoV-2 papain-like protease (7CMD) with a free binding energy of - 8.7 kcal/mol, followed by balsaminol A interacting with the spike receptor binding domain (6VW1) with - 8.5 kcal/mol and balsaminol C had a binding energy of - 8.1 kcal/mol with the main protease (6LU7) comparable to the standard drugs namely ritonavir, nirmatrelvir and remdesivir.
