Quantitative Structure-Activity Relationship (QSAR) studies gained a foothold in the mid-1960s to rationalise the biological activity of medicinally important compounds. Since then, the advancements in computer hardware and software added many new techniques and areas to this field of study. Molecular dynamics (MD) simulations are one such technique in direct drug design approaches. MD simulations have a special place in drug design studies because they decode the dynamics of intermolecular interactions between a biological target and its potential ligands/inhibitors...

Multi-target drug development (MTDD) is the demand of the recent era, especially in the case of multi-factorial conditions such as cancer, depression, neurodegenerative diseases (NDs), etc. The MTDD approaches have many advantages; avoidance of drug-drug interactions, predictable pharmacokinetic profile, and less drug resistance. The wet lab practice in MTDD is very challenging for the researchers, and the chances of late-stage failure are obvious. Identification of an appropriate target (Target fishing) is another challenging task in the development of multi-target drugs...

BACKGROUND: Cannabis is the most widely used illicit substance. Numerous scientific evidence confirm the strong association between cannabis and psychosis. Exposure to cannabis can induce the development of psychosis and schizophrenia in vulnerable individuals. However, the neurobiological processes underlying this relationship are unknown. Neurotrophins are a class of proteins that serve as survival factors for central nervous system (CNS) neurons. In particular, nerve growth factor (NGF) plays an important role in the survival and function of cholinergic neurons while brain-derived neurotrophic factor (BDNF) is involved in synaptic plasticity and the maintenance of midbrain dopaminergic and cholinergic neurons...

The COVID-19 pandemic was the most significant public healthcare crisis worldwide. It was estimated that 80% of infected patients with COVID-19 have not fully recovered and developed one or more long-term symptoms, referred to as post-acute sequelae of COVID-19 (PASC). Seeking a treatment strategy for PASC has become a concerning topic since the sequelae can cause irreversible multiple organ damage and can severely compromise quality of life. It is indicated that PASC may be closely related to lung injury-induced hypoxia, excessive immune response, cytokine storm, gut bacteria imbalance, and endothelial dysfunction...

Cardiac fibrosis is known as the expansion of the cardiac interstitium through excessive deposition of extracellular matrix proteins; this process is performed by a multifunctional cell known as the cardiac fibroblast. After the myocardial injury, these cells are activated as a repair program, increase, and switch to a contractile phenotype, which is evidenced by an increase in alpha-smooth muscle actin. Likewise, there is an increase in type I and III collagen, which are considered profibrotic biomarkers. It is believed that one of the proteins involved in cardiac remodeling is METTL3, which is the enzyme responsible for N6-methyladenosine (m6A) methylation, the most common and abundant epigenetic modification of eukaryotic mRNA...

BACKGROUND: DNA methyltransferases (DNMTs) have been reported to be potential drug targets in various cancers. The major hurdle in inhibiting DNMTs is the lack of knowledge about different DNMTs and their role in the hypermethylation of gene promoters in cancer cells. Lack of information on specificity, stability, and higher toxicity of previously reported DNMT inhibitors is the major reason for inadequate epigenetic cancer therapy. DNMT1 and DNMT3A are the two DNMTs that are majorly overexpressed in cancers...

Hyperglycemia resulting from over-gluconeogenesis is a prominent feature of type 2 diabetes mellitus (T2DM). Therefore, it is very important to reduce glucose output, especially liver glucose output, and maintain blood glucose homeostasis in the treatment of T2DM. It has been found that small molecules of natural flavonoids are able to act on various targets in the gluconeogenic pathways, interfering with rate-limiting enzyme activity or regulating the cascade of hormonal signaling and affecting all levels of transcription factors by limiting the transport of non-sugar substrates...
