Drzał W, Trotsko N. Review of Recent Advances in Thiazolidin-4-One Derivatives as Promising Antitubercular Agents (2021-Present). Molecules 2025; 30:2201. [PMID: 40430372 PMCID: PMC12114044 DOI: 10.3390/molecules30102201] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2025] [Revised: 05/12/2025] [Accepted: 05/15/2025] [Indexed: 05/29/2025] Open
Abstract
Tuberculosis (TB) remains one of the leading causes of mortality worldwide, exacerbated by the emergence of multidrug-resistant (MDR) and extensively drug-resistant (XDR) Mycobacterium tuberculosis strains. In the pursuit of novel therapeutic strategies, thiazolidin-4-one derivatives have gained significant attention due to their structural diversity and broad-spectrum biological activities. This review provides a comprehensive summary of recent advances (2021-present) in the synthesis, structure-activity relationship (SAR), and mechanisms of action of thiazolidin-4-one derivatives as promising antitubercular agents. A detailed discussion of synthetic pathways is presented, including classical and multi-component reactions leading to various subclasses such as thiazolidine-2,4-diones, rhodanines, and pseudothiohydantoins. The SAR analysis highlights key functional groups that enhance antimycobacterial activity, such as halogen substitutions and heterocyclic linkers, while molecular docking and in vitro studies elucidate interactions with key Mtb targets including InhA, MmpL3, and DNA gyrase. Several compounds demonstrate potent inhibitory effects with MIC values lower than or comparable to first-line TB drugs, alongside favorable cytotoxicity profiles. These findings underscore the potential of thiazolidin-4-one scaffolds as a valuable platform for the development of next-generation antitubercular therapeutics.

Design, Synthesis, and Anti-Tyrosinase, Anti-Melanogenic, and Antioxidant Activities of Novel (Z)-3-Benzyl-5-Benzylidene-2-Thioxothiazolidin-4-One Analogs. Molecules 2025; 30:517. [PMID: 39942621 PMCID: PMC11820736 DOI: 10.3390/molecules30030517] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2024] [Revised: 01/22/2025] [Accepted: 01/22/2025] [Indexed: 02/16/2025] Open
Abstract
To discover novel anti-melanogenic compounds with tyrosinase inhibitory activity, (Z)-3-benzyl-5-benzylidene-2-thioxothiazolidin-4-one ((Z)-BBTT) analogs 1-12, designed based on the hybrid structure of a β-phenyl-α,β-unsaturated carbonyl motif and a 3-benzyl-2-thioxothiazolidin-4-one scaffold, were synthesized as novel tyrosinase inhibitors. Of the 12 analogs, 2 (6 and 8) showed mushroom tyrosinase inhibitory activity similar to that of kojic acid, a representative tyrosinase inhibitor, and 3 analogs (1-3) exhibited mushroom tyrosinase inhibitory activity that was more potent than that of kojic acid. In particular, analog 3 revealed highly potent inhibition with an IC50 value of 90 nM, which was 214 times lower than that of kojic acid (IC50 value = 19.22 μM). A kinetic study using mushroom tyrosinase and analogs 1-3 and 6 demonstrated that these analogs were competitive inhibitors, which was further supported by in silico studies. Analogs 1 and 3 have strong anti-melanogenic potency in B16F10 mammalian cells owing to their anti-tyrosinase activity without perceptible cytotoxicity in melanoma cells (B16F10) and the main epidermal cells (HaCaT). Moreover, analog 3 exhibited strong antioxidant capacity, scavenging reactive oxygen species, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) cation radical, and 2,2-diphenyl-1-picrylhydrazyl radical, partially contributing to its anti-melanogenic effect. (Z)-BBTT analogs, including analog 3, may be promising candidates for inhibiting melanin production.

Abstract
This review article delves into the critical role of Enoyl acyl carrier protein reductase (InhA; ENR), a vital enzyme in the NADH-dependent acyl carrier protein reductase family, emphasizing its significance in fatty acid synthesis and, more specifically, the biosynthesis of mycolic acid. The primary objective of this literature review is to elucidate diverse scaffolds and their developmental progression targeting InhA inhibition, thereby disrupting mycolic acid biosynthesis. Various scaffolds, including thiourea, piperazine, thiadiazole, triazole, quinazoline, benzamide, rhodanine, benzoxazole, and pyridine, have been systematically explored for their potential as InhA inhibitors. Noteworthy findings highlight thiadiazole and triazole derivatives, demonstrating promising IC50 values within the nanomolar concentration range. The review offers comprehensive insights into InhA's structure, structure-activity relationships, and a detailed overview of distinct scaffolds as effective inhibitors of InhA.

Abstract
Mycobacterium tuberculosis (M. tb) is a remarkably versatile pathogen that possesses a unique ability to counteract the host's defence mechanisms to control the infection. Several mycobacterial protein kinases and phosphatases were found to play a key role in impeding phagosome maturation in macrophages and accordingly blocking the phagosome-lysosome fusion, therefore allowing the bacteria to survive. During phagocytosis, both M. tb and the host's phagocytic cells develop mechanisms to fight each other, resulting in pathogen elimination or survival. In this respect, M. tb uses a phosphorylation-based signal transduction mechanism, whereby it senses extracellular signals from the host and initiates the appropriate adaptation responses. Indeed, the ability of M. tb to exist in different states in the host (persistent quiescent state or actively replicating mode) is mainly mediated through protein phosphorylation/dephosphorylation signalling. The M. tb regulatory and defensive responses coordinate different aspects of the bacilli's physiology, for instance, cell wall components, metabolic activity, virulence, and growth. Herein, we will discuss the implication of M. tb kinases and phosphatases in hijacking the host immune system, perpetuating the infection. In addition, the role of PknG, MPtpA, MPtpB, and SapM inhibitors in resetting the host immune system will be highlighted.

Abstract
With the rise of multidrug-resistant tuberculosis, the imperative for an alternative and superior treatment regimen, incorporating novel mechanisms of action, has become crucial. In pursuit of this goal, we have developed and synthesized a new series of rhodanine-linked enamine-carbohydrazide derivatives, exploring their potential as inhibitors of mycobacterial carbonic anhydrase. The findings reveal their efficacy, displaying notable selectivity toward the mycobacterial carbonic anhydrase 2 (mtCA 2) enzyme. While exhibiting moderate activity against human carbonic anhydrase isoforms, this series demonstrates promising selectivity, positioning these compounds as potential antitubercular agents. Compound 6d was the best one from the series with a Ki value of 9.5 µM toward mtCA 2. Most of the compounds displayed moderate to good inhibition against the Mtb H37Rv strain; compound 11k showed a minimum inhibitory concentration of 1 µg/mL. Molecular docking studies revealed that compounds 6d and 11k show metal coordination with the zinc ion, like classical CA inhibitors.

Abstract
Rhodanine-3-acetic acid derivatives are attractive compounds with versatile effects. What is very important is that compounds of this type have many biological properties. They are tested, among others, as fluorescent probes for bioimaging and aldose reductase inhibitors. Rhodanine-3-acetic acid derivatives also have antibacterial, antifungal and anticancer activity. The presented work demonstrates that a slight change in the five-membered heterocyclic substituent significantly affects the properties of the compounds under consideration. Three rhodanine-3-acetic acid derivatives (A-1-A-3) were obtained in the Knoevenagel condensation reaction with good yields, ranging from 54% to 71%. High thermal stability of the tested compounds was also demonstrated above 240 °C. The absorption and emission maxima in polar and non-polar solvents were determined. Then, the possibility of using the considered derivatives for fluorescence bioimaging was checked. Compounds A-1 and A-2 were successfully used as fluorescent dyes of fixed cells of mammalian origin. In addition, biological activity tests against bacteria and fungi were carried out. Our results showed that A-1 and A-2 showed the most excellent antimicrobial activity among the newly synthesized compounds, especially against Gram-positive bacteria.

Abstract
Antibiotic resistance associated with various microorganisms such as Gram-positive, Gram-negative, fungal strains, and multidrug-resistant tuberculosis increases the risk of healthcare survival. Preliminary therapeutics becoming ineffective that might lead to noteworthy mortality presents a crucial challenge for the scientific community. Hence, there is an urgent need to develop hybrid compounds as antimicrobial agents by combining two or more bioactive heterocyclic moieties into a single molecular framework with fewer side effects and a unique mode of action. This review highlights the recent advances (2013-2023) in the pharmacology of rhodanine-linked quinoline hybrids as more effective antimicrobial agents. In the drug development process, linker hybrids acquire the top position due to their excellent π-stacking and Van der Waals interaction with the DNA active sites of pathogens. A molecular hybridization strategy has been optimized, indicating that combining these two bioactive moieties with an arylidene and an amino spacer linker increases the antimicrobial potential and reduces drug resistance. Moreover, the structure-activity relationship study is discussed to express the role of various functional groups in improving and decrementing antimicrobial activities for rational drug design. Also, a linker approach may accelerate the development of dynamic antimicrobial agents through molecular hybridization.
