Studies have reported the potential role of Boswellic acids (BAs), bioactive pentacyclic triterpenes from (BS), in treating rheumatoid arthritis (RA). However, poor water solubility and limited oral absorption are restricting factors for its better therapeutic efficacy. Based on these assumptions, the current study aimed to develop naturosomal delivery of BAs to boost their extremely low bioavailability, colloidal stability, and water solubility.

Article Synopsis
  • Alzheimer's disease (AD) is a complex neurodegenerative disorder characterized by memory loss and cognitive decline, with no effective treatments currently available to stop or slow its progression.
  • Research focused on plant-derived polyphenols, which show potential therapeutic effects against Alzheimer’s by targeting key pathological factors like β-amyloid and neuroinflammation; among 120 polyphenols studied, amygdalin demonstrated the best drug potency.
  • These polyphenols exhibited better stability and lower toxicity compared to traditional treatments, but further in vivo studies are necessary to confirm their effectiveness in treating Alzheimer's disease.

The present research demonstrates the formation of zinc oxide nanoparticles facilitated by Cissus quadrangularis (CQ-ZnONPs) and subsequent synthesis of chitosan-conjugated nanocomposites (CQ-CS/ZnONCs) along with their biological assessment. The biosynthesized nanoparticles and nanocomposites were physicochemically characterized and therapeutically assessed for their antioxidant, antibacterial, and antidiabetic potential. The formation of CQ-ZnONPs and CQ-CS/ZnONCs was preliminarily validated by the change in color and subsequently by UV-visible spectroscopic analysis.

The present study intends to formulate, characterize and appraise the phospholipid-based nanovesicular system for enhanced delivery of Hesperetin (HT). The quality by design (QbD) approach was employed to prepare Hesperetin naturosomes (HTN) using the solvent evaporation technique and assessed for physicochemical and pharmacological attributes. The FTIR, DSC, and PXRD studies confirmed the successful formation of a vesicular drug-phospholipid complex, while photomicroscopy, SEM, and TEM analysis revealed the morphology of HTN.
