Protein phosphorylation is a fundamental regulatory mechanism governing a broad spectrum of cellular processes. In the nervous system, it is critical for modulating neurotransmitter release, synaptic plasticity, neuronal excitability, and cell survival. Dysregulation of protein kinase activity is closely linked to the pathogenesis of various neurological and psychiatric disorders, positioning several kinases as promising therapeutic targets. Although protein kinase inhibitors (PKIs), a major class of compounds that modulate kinase activity, have shown considerable therapeutic success in oncology, their application in neurological diseases remains in the early stages of exploration. Of the 82 PKIs approved by the Food and Drug Administration (FDA), 37 are now in various preclinical and clinical trials for neurological conditions, primarily targeting signaling pathways mediated by key protein kinases implicated in these diseases. This review examines the roles of critical protein kinases and the therapeutic effects of their inhibitors in neurodegenerative, psychiatric, and selected neurological disorders, such as autism spectrum disorders (ASD) and epilepsy. We focus on Abelson kinase I (ABL1), calmodulin-dependent kinase II (CaMKII), casein kinase 1δ (CK1δ), c-Jun N-terminal kinase (JNK), cyclin-dependent kinase 5 (CDK5), dual-specificity tyrosine-phosphorylated and regulated kinase 1A (DYRK1A), leucine-rich repeat kinase 2 (LRRK2), extracellular signal-regulated kinase 1/2 (ERK1/2), glycogen synthase kinase 3β (GSK3β), mammalian target of rapamycin (mTOR), p38 mitogen-activated protein kinase, and protein kinase C (PKC) in neurodegenerative diseases. Additionally, we discuss CaMKII, CDK5, ERK1/2, PI3K/AKT/GSK3, protein kinase A (PKA), and PKC in psychiatric disorders, focusing on schizophrenia and mood disorders, and analyze GSK3β, ERK1/2, and mTOR in ASD and epilepsy. This review underscores the therapeutic potential of PKIs in neurological disorders while highlighting ongoing challenges and the need for further research to refine kinase-targeted therapies.

Ischemic stroke (IS) is a leading cause of death globally. IS occurs due to a blockage of cerebral arteries, leading to neuronal injury, tissue death, and brain infarcts. This induces lack of oxygenation to the brain which induces neuroinflammation, characterised by interactions involving molecules which can exacerbate brain damage but also aid recovery through processes like microglial phagocytosis. Post-stroke depression (PSD) affects 30–33% of stroke survivors, complicating recovery with various symptoms. The pathophysiology of PSD involves disruptions in the glutamatergic and monoaminergic systems, the gut-brain axis, and neuroinflammation. Agomelatine, an atypical antidepressant, can potentially treat both IS and PSD. It acts as a melatonin receptor agonist and a serotonin receptor antagonist, enhancing dopamine and norepinephrine availability in the prefrontal cortex. Agomelatine’s neuroprotective, anti-inflammatory, antioxidative, and antiapoptotic properties have been demonstrated in research, where it reduces reactive oxygen species (ROS) levels and activates the Nrf2 pathway, promoting antioxidative enzyme expression. Additionally, it prevents microglial activation by inhibiting the toll-like receptor 4 (TLR4)/nucleotide-binding domain, leucine-rich-containing family, pyrin domain-containing-3 (NLRP3) pathway, thus reducing inflammation. This review examines the pathophysiology of IS and PSD, highlighting agomelatine’s multifaceted therapeutic potential. Agomelatine’s distinct pharmacological profile and minimal side effects make it a compelling candidate for IS and PSD treatment, necessitating further exploration to optimise stroke management and improve patient outcomes.

Over the last 60 years, only four new classes of antibiotics have been introduced, while the prevalence of antibiotic-resistant Gram-positive and Gram-negative bacteria has risen. This underscores the urgent need for new antibacterial therapeutics. This commentary leverages the recent exploration of γ-substituted-N-acylated-N-aminoethyl amino acid peptides (γ-AApeptides) to mimic the structures and function of natural antimicrobial peptides (AMPs), highlighting the promise and limitations for developing a new, effective treatment for antibiotic-resistant bacteria.

Antibiotic resistance is a significant threat to public health and drug development, driven largely by the overuse and misuse of antibiotics in medical and agricultural settings. As bacteria adapt to evade current drugs, managing bacterial infections has become increasingly challenging, leading to prolonged illnesses, higher healthcare costs, and increased mortality. This review explores the critical role of antibiotics in fighting infections and the mechanisms that enable bacteria to resist them. Key antibiotics discussed include carvacrol, dalbavancin, quinolones, fluoroquinolones, and zoliflodacin, each with unique actions against bacterial pathogens. Bacteria have evolved complex resistance strategies, such as enzyme production to neutralize drugs, modifying drug targets, and using efflux pumps to remove antibiotics, significantly reducing drug efficacy. Additionally, the review examines the challenges in antibiotic development, including a declining discovery rate of novel drugs due to high costs and regulatory complexities. Innovative approaches, such as structure-based drug design, combination therapies, and new delivery systems, are highlighted for their potential to create compounds with enhanced action against resistant strains. This review provides valuable insights for researchers and developers aiming to combat antibiotic resistance and advance the development of robust antibacterial therapies for future health security.

Lutein, a natural dihydroxy carotenoid and a member of the non-vitamin A carotenoids family, is abundant in yellow-colored fruits and green leafy vegetables such as spinach and lettuce. As the second most common type of carotenoid found in human serum, lutein offers a plethora of medicinal benefits, including anti-cancer, anti-inflammatory, and anti-oxidative properties. It is well-absorbed and systemically localized to the liver, lung, and retina, where it can cross the blood-retina barrier and accumulate in the macular pigment. Due to its anti-oxidative and singlet oxygen quenching properties, lutein is reported to reduce the risk of age-related macular degeneration (AMD). Higher concentrations of fasting plasma carotenoids and enhanced skin yellowing after lutein consumption indicate its presence in various regions of the human body, including the skin, breast, brain, and cervix. Lutein has remarkable benefits for neurodegenerative diseases, cardiovascular health, liver protection, and bone disease prevention. In the central nervous system (CNS), lutein supports brain homeostasis through its antioxidant and anti-inflammatory properties, increasing interleukin-10 (IL-10) and reducing tumor necrosis factor-α (TNF-α). It reduces the risk of coronary artery disease and exerts anti-inflammatory effects on peripheral blood mononuclear cells (PBMCs). Lutein protects against alcohol-induced liver damage by modulating the nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) signaling pathway. Additionally, lutein promotes bone health by enhancing mineralized bone nodule development and inhibiting osteoclast production, reducing bone resorption, and suppressing soluble receptor activator of nuclear factor kappa B ligand (RANKL). These multifaceted benefits make lutein a valuable agent in disease prevention and health promotion. This review discusses the comprehensive profile of lutein as a phytochemical activity, including anti-inflammatory, antioxidant, anti-cancer, hepatoprotective, neurological, and cardioprotective effects. Additionally, it discusses lutein’s beneficial impact on macular degeneration and eye diseases, showcasing its potential as a natural, plant-based therapeutic agent.

Microbial biotransformations are valuable tools from “green chemistry” and involve converting parental molecules into new daughter ones with unique physical, chemical, or pharmacological properties. These reactions are often carried out by cells grown under a planktonic phenotype. However, microbial cells grown under a phenotype of biofilm can improve biotransformation bioprocesses once they form more biomass per volume, are more resistant to extreme conditions (pH, temperature, and toxic substances), remain active for extended periods, are less prone to cell washouts, and reduce re-inoculation demands, leading to increased production rates due to their unique physiological features. In addition, experience has shown that biofilms may furnish a broader array of new daughter molecules. This review highlighted the benefits of using biofilms in microbial biotransformations to obtain a variety of bioactives.

The integration between the tumor-suppressive and oncogenic signaling pathways controls various cellular activities of cancer cells, including cell growth and apoptosis. While the activation of oncogenes fuels cancer progression and escape mechanisms, tumor suppressors regulate and counterbalance the negative effects of oncogenic signaling. Notably, phosphatase and tensin homolog (PTEN) constitute one of the important family members of tumor suppressor genes, which play critical roles in regulating the activities of tumor cells. Thus, an impaired, mutated, or loss of PTEN is associated with low survival or high tumor recurrence rates in cancer patients. Importantly, high tumor expression of a G-protein coupled platelet-activating factor-receptor (PAFR) is associated with increased tumor progression as well as decreased overall survival and poor prognosis in malignancies such as non-small cell lung cancer (NSCLC). Along similar lines, overactivation or mutations in epidermal growth factor receptor (EGFR) signaling are detected in various human malignancies and associated with poor prognosis. The goal of the current minireview was to highlight the significance of the mechanistic insights between the PTEN and PAFR as well as the PAFR and EGFR pathways in impacting cancer growth and/or efficacy of therapeutic agents in experimental model systems.

Sirtuins are a family of NAD⁺-dependent class III histone deacetylases that regulate histones and other proteins. The mammalian sirtuins comprise seven members that have a role in energy metabolism, DNA repair, inflammation, cell survival, apoptosis, cellular senescence, oxidative stress, and mitochondrial production. Sirtuin modulation may have beneficial effects on aging and age-related diseases; thus, attracting a growing interest in discovering small molecules modifying their activity. A class of compounds both natural and chemically synthesized has emerged as sirtuin activators. This review discusses mammalian sirtuins in aging, the small molecules that activate sirtuins, modulation of sirtuin activity, and its impact in alleviating the effects of aging.
