Functionalized Calixarenes as Promising Antibacterial Drugs
Since the discovery of polyphenolic resins 150 years ago, the study of polymeric compounds named calix[n]arene has continued to progress, and those skilled in the art perfectly know now how to modulate this phenolic ring. Consequently, calix[n]arenes are now used in a large range of applications and notably in therapeutic fields. In particular, the calix[4]arene exhibits multiple possibilities for regioselective polyfunctionalization on both of its rims and offers researchers the possibility of precisely tuning the geometry of their structures. Thus, in the crucial research of new antibacterial active ingredients, the design of calixarenes finds its place perfectly. Out of all the work of the community, there are some excellent activities emerging that could potentially place these original structures in a very good position for the development of new active ingredients.

Food-Based Carbon Dots for Biomedical Applications
Thermal treatment is one of the common methods used in food processing to reduce microbial activity and control the presence of foodborne pathogens. During thermal processing, carbonization reactions are often observed in foods, which could result in the formation of carbon dots (CDs). Typical CDs are regarded as organic carbonization products with sizes less than 20 nm, exhibiting excitation-dependent fluorescence properties. They possess sp2/sp3 carbon skeletons and feature an abundance of functional groups and polymer chains within their structures. The surface of CDs is rich in hydrophilic compounds, including carboxyl, hydroxyl, and amine groups, contributing to their excellent water dispersibility.

Polydynamic Biological Activity of Quercetin
Quercetin is one of those natural products. It belongs to the family of flavonoids and, more specifically, flavonols. Quercetin is an organic compound that belongs to the family of flavonoids, with a wide range of medical properties. Some of these include anti-allergy, anti-inflammatory, anticancer, anti-tumor, and antiviral properties as well as cardiovascular protection. It has also been found that quercetin plays a vital role in plants. Specifically, quercetin has antioxidant and antimicrobial activities, and as a result, it contributes to photosynthesis, growth, and seed germination. Moreover, the presence of quercetin in various regions of the brain contributes to combatting against various neurological diseases such as Alzheimer’s and Parkinson’s.

2-Substituted Benzimidazoles as Photo-Protective Agents
The modern trend in sunscreen products is towards the development of UV filters with multi-functional properties, to provide a broad shielding against ultraviolet radiation, antioxidant activity, and the prevention of skin cancer. Additionally, they should also be safe for humans as well as the environment. The benzimidazole heterocycle is a suitable platform for the development of such multifunctional molecules with potential application in cosmetic formulations, due to their ability to act as both UV protectors and reactive pharmacophores.

Radiolabeled Peptoids and Peptoid/Peptide Hybrids for Cancer-Targeted Imaging
Peptoids (N-substituted glycine oligomers) are a relatively new class of peptidomimetics, being highly versatile and capable of mimicking the architectures and the activities of the peptides but with a marked resistance to proteases and a propensity to cross the cellular membranes over the peptides themselves. For these properties, they have gained an ever greater interest in applications in bioengineering and biomedical fields.

Molecular Hybridization of Alkaloids Using 1,2,3-Triazole-Based Click Chemistry
Alkaloids found in multiple species, known as ‘driver species’, are more likely to be included in early-stage drug development due to their high biodiversity compared to rare alkaloids. Many synthetic approaches have been employed to hybridize the natural alkaloids in drug development. Click chemistry is a highly efficient and versatile reaction targeting specific areas, making it a valuable tool for creating complex natural products and diverse molecular structures. It has been used to create hybrid alkaloids that address their limitations and serve as potential drugs that mimic natural products.
