Fatty acids as molecular carriers in cleavable antifungal conjugates

Trimethyl Lock Based Tools for Drug Delivery and Cell Imaging - Synthesis and Properties

Trimethyl lock (TML) systems have become increasingly important in medicinal and bioorganic chemistry, particularly for their roles in the targeted delivery of therapeutic agents and as integral components in fluorogenic probes for cellular imaging. The simplicity and efficiency of their synthesis have established TML systems as versatile platforms for the controlled release of active molecules under particular physiological conditions. This review consolidates recent advancements in the application of TML systems, with a focus on their use in drug delivery, cellular imaging, and other areas where precise molecular release is crucial. Additionally, we discuss the synthetic strategies employed to construct TML-based conjugates, underscoring their potential to enhance the specificity and efficacy of bioactive compounds in various biomedical applications.

Searching for Conjugates as New Structures for Antifungal Therapies

The progressive increase in fungal infections and the decrease in the effectiveness of current therapy explain research on new drugs. The synthesis of compounds with proven antifungal activity, favorable physicochemical and pharmacokinetic properties affecting their pharmaceutical availability and bioavailability, and limiting or eliminating side effects has become the goal of many studies. The publication describes the directions of searching for new compounds with antifungal activity, focusing on conjugates. The described modifications include, among others, azoles or amphotericin B in combination with fatty acids, polysaccharides, proteins, and synthetic polymers. The benefits of these combinations in terms of activity, mechanism of action, and bioavailability were indicated. The possibilities of creating or using nanoparticles, "umbrella" conjugates, siderophores (iron-chelating compounds), and monoclonal antibodies were also presented. Taking into account the role of vaccinations in prevention, the scope of research related to developing a vaccine protecting against fungal infections was also indicated.
