TL;DR: The progress made in the stereoselective synthesis of spiro-β-lactams, a unique class of heterocycles, their biological evaluation, and their applications in various related fields are reviewed.
Abstract: β-Lactam rings containing compounds are a group of antibiotics of unparalleled importance in chemotherapy. Considerable effort has been reported in the development of novel, more effective β-lactam compounds as well as their biological evaluation. This article reviews the progress made in the stereoselective synthesis of spiro-β-lactams, a unique class of heterocycles, their biological evaluation, and their applications in various related fields. The introductory paragraph highlights the significance of the β-lactam chemistry and is followed by an overview of monocyclic-, bicyclic-, and tricyclic-β-lactams. The other sections of the article deal with the stereoselective synthesis and biological evaluation of spiro-β-lactams, including their use as synthetic intermediates for β-turn mimics and β-turn nucleators. The potential of spiro-β-lactams as cholesterol absorption inhibitors, β-lactamase inhibitors, and antiviral, antibacterial, and antimicrobial agents has also been described.

TL;DR: The less fluorescence quenching efficiency of quercetin-PLA nanoparticles than free quercETin on BSA confirms the controlled release of quERCetin from PLA nanoparticles and pave way for encapsulating various therapeutically less useful highly active antioxidant molecules towards the development of better therapeutic compounds.
