The use of in-silico research in drug development is growing. Aspects of drug discovery and development, such as virtual ligand screening and profiling, target and lead finding, and compound library creation, are simulated by computational approaches. Databases, pharmacophores, homology models, quantitative structure–activity connections, machine learning, data mining, network analysis tools, and computer-based data analysis tools are examples of in-silico techniques. These techniques are mostly applied in conjunction with the production of in vitro data to build models that facilitate the identification and refinement of new compounds by providing insight into their features related to absorption, distribution, metabolism, and excretion.

Cowhide collagen hydrolysates (CCHs) are peptides and amino acids obtained from the partial hydrolysis of collagen. These have numerous potential applications in the food, biomedical, and pharmaceutical industries. The study analyzed the physicochemical, antioxidant, and anti-atherosclerosis properties of collagen hydrolysates (CCHs) from cowhide using in silico methods. Proteins were identified in silico based on their molecular weights and origin from the protein database (UniProtKB). Using bioinformatics tools, numerous physicochemical properties (toxicity and amino acid composition) were determined. The identified proteins were subsequently subjected to an in silico enzymatic hydrolysis using pepsin, thermolysin, and proteinase K. The peptides obtained were characterized. Molecular docking was conducted between the peptides generated in silico and the three target enzymes (3-Hydroxy-3-Methylglutaryl-CoA (HMG-CoA) reductase, cyclooxygenase-2, and Nicotinamide Adenine Dinucleotide Phosphate (NADPH) oxidase). Two cowhide collagens were identified, F1MJQ6 and G3MZI7, with molecular weights of 172,076 and 184,867 ​Da, respectively. A compositional analysis of F1MJQ6 and G3MZI7 revealed the significant presence of glycine residues at 25% and 23%, and proline residues at 16% and 18%, respectively. The G3MZI7 and F1MJQ6 proteins exhibited a high concentration of both essential and semi-essential amino acids. The molecular docking results indicate that the antioxidant peptides ADF, PHF, and LW (novel potential anti-atherosclerosis peptides released by enzymatic hydrolysis with pepsin, thermolysin, and proteinase K) are the most promising candidates for further development as inhibitors of HMG-CoA reductase, cyclo-oxygenase-2, and NADPH oxidase. In silico analysis revealed that cowhide collagen hydrolysates exhibited particularly significant antioxidant and anti-atherosclerosis properties.

Alzheimer's disease (AD) is a brain disorder that is known to be one of the deadliest diseases affecting humanity, especially adults from the age of sixty (60) years and above. It mostly affects thinking ability, behaviour and social skills, eventually, AD causes the brain to shrink and brain cells to die. To curb the menace of this disease, virtual screening of potent, non-toxic hybrid natural therapeutic inhibitors was performed on some inhibitors of AD. We performed simulations on the screened compounds and predicted their druggability. A model with satisfactory statistical properties was developed in this study. The ligands underwent molecular docking, C-19 exhibited the highest docked score of −12.8 ​kcal/mol against the target, while the referenced compound (harmine) indicated the lowest docked score of −8.2 ​kcal/mol. The docked complex was validated using molecular dynamic simulations. Trajectory plots of C-19 were obtained and found to be stable. C-19 was stable during the 100 ns intervals which implies that the compounds were better than the referenced compound. In addition, ADMET has demonstrated that these ligands have good pharmacokinetic properties. All the evaluations were more comprehensive and beneficial to researchers and the medical community as outstanding results were obtained.

The increasing quest for therapeutic alternatives in treating non-communicable chronic diseases like obesity has propelled research into bioactive peptides, with a particular focus on milk due to its rich protein composition and associated health benefits. Milk fermentation, a traditional process in dairy production, enhances the bioactivity of peptides, broadening their potential therapeutic uses. This study investigated the anti-obesity potential of peptides from bovine milk fermented by Lacticaseibacillus casei LBC 237, identifying 143 peptides, notably LGPV and EVPMP. In silico analyses revealed that LGPV and EVPMP biopeptides exhibited significant interactions with target proteins, employing various molecular interactions such as Van der Waals forces, hydrogen bonds, and electrostatic interactions. These peptides shared common binding sites in some enzymes, suggesting a similar mode of interaction between molecule and target protein, akin to key pharmaceuticals recommended for treating these pathologies. Furthermore, amino acid characteristics present in the peptides, including hydrophobic residues like Leucine, Glutamate, Valine, and Proline, proved essential for their bioactive and inhibitory activities. These findings highlight the potential of LGPV and EVPMP biopeptides as therapeutic agents in managing obesity and metabolic disorders. They provide important insights into their mechanisms of action, paving the way for future research to apply them practically in preventing and treating metabolic conditions.

Breast cancer remains a significant global health concern, necessitating the exploration of novel preventive and therapeutic strategies. Dietary interventions have gained substantial attention due to their potential to modulate cancer risk and progression. Millets, a group of small-seeded grasses, have emerged as promising candidates in this regard, owing to their rich nutritional composition and diverse bioactive compounds. Among these bioactive compounds, phytate antinutrients have garnered considerable interest for their potential health benefits. This review aims to unravel the intricacies of phytate antinutrients in millets and their therapeutic implications in breast cancer. Phytates are naturally occurring compounds present in various plant-based foods, including millets, and are known for their ability to chelate minerals and inhibit their bioavailability. However, recent research has shed light on the multifaceted properties of phytates, highlighting their potential as functional bioactive molecules. Phytates exhibit various anticancer properties, including “antioxidant, anti-inflammatory, and antiproliferative effects”, which have been shown to inhibit the growth and progression of breast cancer cells. Additionally, phytates have been reported to modulate key signaling pathways involved in cancer development, such as PI3K/Akt, MAPK, and NF-κB, thereby exerting their anticancer effects. Moreover, phytates demonstrate the potential to enhance the efficacy of conventional breast cancer treatments, such as chemotherapy and radiation therapy, while mitigating their adverse effects. Furthermore, the bioavailability and metabolism of phytates are complex processes influenced by factors such as food processing, gut microbiota composition, and genetic variations. Understanding these intricacies is crucial for harnessing the full potential of phytates in breast cancer prevention and treatment. In conclusion, this review provides a comprehensive overview of the intricate roles of phytate antinutrients in millets and their therapeutic implications in breast cancer. The findings suggest that millets, as a rich source of phytates, could be incorporated into dietary strategies to reduce breast cancer risk and complement existing therapeutic approaches. However, further research is warranted to elucidate the precise mechanisms of action, optimal dosage, and potential synergistic effects with other bioactive compounds. The information that is given here is supported by accurate facts and arguments that have undergone rigorous scrutiny.

Background

The COVID-19 pandemic significantly affects patients with RA and other rheumatic diseases. Our study aims to explore the factors associated with COVID-19-related fatality among Rheumatoid Arthritis (RA) patients, especially immunomodulatory therapies, using the international Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS).

Methods

Reportes from FAERS were extracted from February 2020 to September 2022, and uesd for this cross-sectional analysis. The investigative outcome was COVID-19-related death. Age, sex, region, event date, and immunomodulatory medications classies were included as co-variates in multivariable logistic regression. In view of the different targeting and affinity of individual JAKi, Tofacitinib, Upadacitinib and Baricitinib was respectively analyzed.

Results

In all, 3808 cases (mean age 58.85 years, 82.8% female), 267 (7.0%) died. JAKi therapies (41.2%), followed by TNFi (37.7%), IL-1i (12.2%), IL-6i (4.1%) and Anti-CD20 (3%) were reported. Risk factors associated with COVID-19-related death in RA patients were age (odds ratio [OR]: 1.06; 95% confidence interval [CI]: 1.05–1.08; p ​< ​0.01), male sex (1.71, 1.26–2.33; p ​= ​0.01) and anti-CD20 therapies (5.05; 1.40–18.19; p ​= ​0.013). With TNFi conference, anti-CD20 was still a risk predictor (4.29; 2.39–7.70; p ​< ​0.01). Other DMARDs except for anti-CD20, did not confer a significant association with mortality, compared with csDMARDs or TNFi. Individual JAKi showed no obvious difference in the risk of death, compared with csDMARDs or TNFis.

Conclusions

Conclusions Using FAERS open access data for risk prediction of death, anti-CD20 therapies were recognized as a risk factor for COVID-19-related fatalities among RA patients, other immunomodulatory therapies were not associated with mortality, compared with csDMARDs or TNFis.

The field of oral drug delivery has witnessed significant advancements, with a focus on developing innovative formulations to address challenges associated with traditional dosage forms, especially for patients with difficulties in swallowing. Fast Dissolving Tablets (FDTs) have emerged as a promising class of tablets designed to rapidly disintegrate or dissolve in saliva, providing a convenient and patient-friendly alternative for various populations.

This article explores the unique properties, advantages, and potential applications of FDTs, emphasizing their role in overcoming challenges posed by conventional oral drug delivery systems. FDTs offer rapid dissolution within 15-120 seconds in the buccal cavity, facilitating direct absorption through the buccal mucosa and ensuring quick therapeutic effects. This characteristic proves particularly beneficial for individuals facing swallowing challenges, such as pediatric and geriatric patients, or those with conditions like dysphagia.

Recognizing the significance of FDTs, the European Pharmacopoeia (EP) has officially recognized them as “oral dissolving tablets," highlighting their acceptance in both academic and industrial settings. The article delves into the anatomical and physiological characteristics of the oral cavity, shedding light on the buccal epithelium, oral mucosa vascularization, and salivary flow, which play crucial roles in drug absorption.

The ideal features of FDTs include rapid dissolution or disintegration, high drug load capacity, masking of bitter taste, positive mouth feel, ease of transport, and reduced sensitivity to environmental factors. The advantages of FDTs extend to their administration for patients unable to swallow, convenient treatment for bedridden and mobile patients, enhanced mouth feel and taste masking, ease of administration, and precise dosing.

Despite their advantages, FDTs come with limitations, including issues related to mechanical strength, hygroscopic nature, brittleness, and challenges with bitter drugs or unpleasant odors. Overcoming these challenges requires a careful formulation approach to balance rapid disintegration with mechanical strength and taste masking.

The article also discusses the salient characteristics of Fast Dissolving Dosage Forms (FDDDS) and various techniques for preparing FDTs, such as freeze-drying, tablet molding, and spray drying. Additionally, it explores the role of non-invasive drug delivery systems in addressing pharmaceutical industry needs, including improving drug half-life, solubility/stability, and bioavailability.
