The emergence of multidrug-resistant (MDR) pathogens is a major problem in the therapeutic management of infectious diseases. Among the bacterial resistance mechanisms is the development of an enveloped protein and polysaccharide-hydrated matrix called a biofilm. Polyphenolics have demonstrated beneficial antibacterial effects. Phenolic compounds mediate their antibiofilm effects via disruption of the bacterial membrane, deprivation of substrate, protein binding, binding to adhesion complex, viral fusion blockage and interactions with eukaryotic DNA. However, these compounds have limitations of chemical instability, low bioavailability, poor water solubility and short half-lives. Nanoformulations offer a promising solution to overcome these challenges by enhancing their antibacterial potential. This review summarizes the antibiofilm role of polyphenolics, their underlying mechanisms and their potential role as resistance-modifying agents.

Millions of people worldwide suffer from cancer, facing challenges such as treatments affecting healthy cells, suboptimal responses, adverse effects, recurrence risk, drug resistance, and nonspecific targeting. Chemoresistance leads to fatalities, but phytoactives show promise in cancer management despite limitations such as high metabolism, poor absorption, and high dosage requirements. Challenges in the large-scale isolation of phytoactive compounds, solubility, bioavailability, and targeting limit their development.

Alzheimer's disease (AD), a progressiveneurodegenerative condition is marked by extensive damage in the brain and dementia. Among the pathological hallmarks of AD is beta-amyloid (Aβ). Production of toxic Aβ oligomers production and accumulation in the brain is among the characteristic features of the disease.

Infectious acute pneumonia caused by bacteria has been a great challenge to human health for long time, and the rapid clearance of aerosolized antibiotics in the lungs restricts their clinical application. The development of nanoformulations with facile preparation and mucoadhesive properties for the pulmonary delivery of antibiotics is thus significant for the treatment of infectious acute pneumonia. In this study, FDA (Food and Drug Administration)-approved tannic acid (TA) was used to construct mucoadhesive nanoformulations through the facile coating of chitosan (CS) to achieve long-lasting anti-infection effects against infectious acute pneumonia.

Theaflavins, powerful antioxidants found in black tea (Camellia sinensis), have garnered increasing interest for their promising therapeutic potential. Experimental studies have contributed to enlightening about the advantages of theaflavins, including their antioxidant, anti-inflammatory, anticancer, antiosteoporosis, and antimicrobial properties. Theaflavin and its derivatives, particularly theaflavin-3,3'-digallate, have been particularly noted for their enhanced action in different areas.
