Throughout history, biopharmaceuticals have been essential in addressing health crises and enhancing human well-being. With advancements in genetic engineering, biotechnology, and bioinformatics, the development and approval rates of new biopharmaceuticals have surged, placing them at the forefront of the pharmaceutical field. Modern manufacturing processes and streamlined regulatory pathways have further expedited approval timelines, providing hope for previously untreatable conditions and significantly improving patients’ quality of life worldwide. However, despite these advancements, ambiguity persists regarding the definition of biopharmaceuticals due to the use of varied terms and a lack of standardized definitions. This article addresses this confusion by proposing a clear and comprehensive definition of biopharmaceuticals. Additionally, we present a reclassification of biopharmaceuticals into seven distinct verticals based on their functions. We assert that biopharmaceuticals not only offer superior therapeutic benefits for human health but also contribute to environmental sustainability, promoting a healthier planet. Thus, this article aims to clarify the scope of biopharmaceuticals and advocate for their broader adoption in the pursuit of global health and environmental integrity.

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.

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.

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.
