Advances in drug design and therapeutic potential of selective or multitarget 5-HT1A receptor ligands. Med Res Rev 2024. [PMID: 38808959 DOI: 10.1002/med.22049] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Revised: 03/14/2024] [Accepted: 05/03/2024] [Indexed: 05/30/2024]
Abstract
5-HT1A receptor (5-HT1A-R) is a serotoninergic G-protein coupled receptor subtype which contributes to several physiological processes in both central nervous system and periphery. Despite being the first 5-HT-R identified, cloned and studied, it still represents a very attractive target in drug discovery and continues to be the focus of a myriad of drug discovery campaigns due to its involvement in numerous neuropsychiatric disorders. The structure-activity relationship studies (SAR) performed over the last years have been devoted to three main goals: (i) design and synthesis of 5-HT1A-R selective/preferential ligands; (ii) identification of 5-HT1A-R biased agonists, differentiating pre- versus post-synaptic agonism and signaling cellular mechanisms; (iii) development of multitarget compounds endowed with well-defined poly-pharmacological profiles targeting 5-HT1A-R along with other serotonin receptors, serotonin transporter (SERT), D2-like receptors and/or enzymes, such as acetylcholinesterase and phosphodiesterase, as a promising strategy for the management of complex psychiatric and neurodegenerative disorders. In this review, medicinal chemistry aspects of ligands acting as selective/preferential or multitarget 5-HT1A-R agonists and antagonists belonging to different chemotypes and developed in the last 7 years (2017-2023) have been discussed. The development of chemical and pharmacological 5-HT1A-R tools for molecular imaging have also been described. Finally, the pharmacological interest of 5-HT1A-R and the therapeutic potential of ligands targeting this receptor have been considered.

Basic Clin Pharmacol Toxicol 2023; 133:473-484.

Abstract
Fluorescence microscopy has revolutionized the visualization of physiological processes in live-cell systems. With the recent innovations in super resolution microscopy, these events can be examined with high precision and accuracy. The development of fluorescently labelled small molecules has provided a significant advance in understanding the physiological relevance of targeted proteins that can now be visualized at the cellular level. One set of physiologically important target proteins are the monoamine transporters (MATs) that play an instrumental role in maintaining monoamine signalling homeostasis. Understanding the mechanisms underlying their regulation and dysregulation is fundamental to treating several neuropsychiatric conditions such as attention deficit hyperactivity disorder (ADHD), anxiety, depression and substance use disorders. Herein, we describe the rationale behind the small molecule design of fluorescently labelled ligands (FLL) either as MAT substrates or inhibitors as well as their applications to advance our understanding of this class of transporters in health and disease.

Abstract
Five new derivatives were obtained utilizing 4-chloro-7-nitrobenzofurazan (NBD-chloride) in combination with furfurylamine, adamantylamine, aminohippuric acid, phenylalanine, and dehydroabietylamine. These derivatives were then subjected to a comparative analysis of their physical, chemical, and certain biological properties alongside two analogous and known compounds derived from the glycine and 4-amino-TEMPO free radical.

Environmentally sensitive photosensitizers enable targeted photodynamic ablation of Gram-positive antibiotic resistant bacteria. Theranostics 2023; 13:3814-3825.

Abstract
Bacterial infections remain among the biggest challenges to human health, leading to high antibiotic usage, morbidity, hospitalizations, and accounting for approximately 8 million deaths worldwide every year. The overuse of antibiotics and paucity of antimicrobial innovation has led to antimicrobial resistant pathogens that threaten to reverse key advances of modern medicine. Photodynamic therapeutics can kill bacteria but there are few agents that can ablate pathogens with minimal off-target effects. Methods: We describe nitrobenzoselenadiazoles as some of the first environmentally sensitive organic photosensitizers, and their adaptation to produce theranostics with optical detection and light-controlled antimicrobial activity. We combined nitrobenzoselenadiazoles with bacteria-targeting moieties (i.e., glucose-6-phosphate, amoxicillin, vancomycin) producing environmentally sensitive photodynamic agents. Results: The labelled vancomycin conjugate was able to both visualize and eradicate multidrug resistant Gram-positive ESKAPE pathogens at nanomolar concentrations, including clinical isolates and those that form biofilms. Conclusion: Nitrobenzoselenadiazole conjugates are easily synthesized and display strong environment dependent ROS production. Due to their small size and non-invasive character, they unobtrusively label antimicrobial targeting moieties. We envisage that the simplicity and modularity of this chemical strategy will accelerate the rational design of new antimicrobial therapies for refractory bacterial infections.

Abstract
Small molecule NSC243928 binds with LY6K, a potential target for the treatment of triple-negative breast cancer, and induces cancer cell death with an unclear mechanism. We have developed chemical tools to identify the molecular mechanisms of NSC243928-LY6K interaction. Herein, we report on the development and synthesis of biotinylated and fluorophore-tethered derivatives of NSC243928 guided by docking studies and molecular dynamics. Surface plasmon resonance assay indicates that these derivatives retained a direct binding with LY6K protein. Confocal analysis revealed that nitrobenzoxadiazole (NBD) fluorophore tagged NSC243928 is retained in LY6K expressing cancer cells. These novel modified compounds will be employed in future in vitro and in vivo studies to understand the molecular mechanisms of NSC243928 mediated cancer cell death. These studies will pave the path for developing novel targeted therapeutics and understanding any potential side-effects of these treatments for hard-to-treat cancers such as triple-negative breast cancer or other cancers with high expression of LY6K.

Abstract
Fluorescent chemical probes are used nowadays as a chemical resource to study the physiology and pharmacology of several important endogenous receptors. Different fluorescent groups have been coupled with known ligands of these receptors, allowing the visualization of their localization and trafficking. One of the most important molecular players of innate immunity and inflammation are the Toll-Like Receptors (TLRs). These Pattern-Recognition Receptors (PRR) have as natural ligands microbial-derived pathogen-associated molecular patterns (PAMPs) and also endogenous molecules called danger-associated molecular patterns (DAMPs). These ligands activate TLRs to start a response that will determine the host's protection and overall cell survival but can also lead to chronic inflammation and autoimmune syndromes. TLRs action is tightly related to their subcellular localization and trafficking. Understanding this trafficking phenomenon can enlighten critical molecular pathways that might allow to decipher the causes of different diseases. In this chapter, the study of function, localization and trafficking of TLRs through the use of chemical probes will be discussed. Furthermore, an example protocol of the use of fluorescent chemical probes to study TLR4 trafficking using high-content analysis will be described.
