Several heterocyclic scaffolds are considered privileged structures. The term Thiadiazole comes from the \"Hantzsch-Widman\" nomenclature and falls within the category of azole chemicals. These are heterocyclic compounds with 5-membered rings that contain 2 nitrogen atoms and 1 sulfur atom. It exists in 4 isomeric forms, namely 1,2,4-thiadiazole, 1,2,3-thiadiazole, 1,3,4-thiadiazole, and 1,2,5- thiadiazole. The thiadiazole nucleus shows a broad spectrum of biological activities, including antimicrobial, anticonvulsant, anticancer, antiviral, antituberculosis, anti-inflammatory and analgesic, diuretic, antidiabetic, anti-ulcer, antimalarial, and anti-leishmanicidal properties, as well as effects against influenza, hypolipidemia, hyperlipidemia, and hypertension. The most studied of these scaffolds is the 1,3,4-thiadiazole scaffold, and the synthesis of 1,3,4-thiadiazole proceeds through wellestablished reaction pathways, including the intramolecular cyclization of thioacylated intermediates, including acylhydrazide or thiosemicarbazide derivatives, which are either acid- or basecatalyzed and often facilitated by harsh dehydrating agents. The review also addresses the chemical reactivity, substitution behaviour, and stability of the scaffold under various conditions, thereby making it more adaptable for molecular design. Aromatic stability, unique electron distribution, and bioisosteric physicochemical and electronic characteristics of the 1,3,4-thiadiazole core result in improved pharmacodynamic and pharmacokinetic performance, and the use of the 1,3,4-thiadiazole ring is currently and, in the future, a major structural motif in drug discovery.

However, FMTs are not merely miniature versions of ETs; they represent an innovative dosage form that delivers health benefits and offers numerous advantages that traditional ETs cannot provide. Fast-melt tablets (FTs), which may resemble FMTs, are also discussed in comparison with both ETs and FMTs. This review aims to explore the functional similarities and differences among FMTs, conventional ETs, and FTs, as well as the mechanisms underlying these variations. For example, FMTs have a higher active load and a quicker release of active ingredients than FTs due to their higher specific surface area (SSA). FMTs can also combine incompatible actives into a single dose, delivering synergistic health benefits from a mixture of different tablets. Multiple means of consumption are another key and distinct attribute of FMTs, as they can be consumed either by dissolving in water and drinking or by taking them directly to the mouth. In contrast, ETs can only be consumed after complete disintegration in water, whereas FTs are taken directly in the mouth. It is also noted that FTs disintegrate more quickly than FMTs and ETs, which are easier for people with swallowing difficulties. The mechanism for rapid disintegration of FTs is quite different: the dry tablet is placed in the mouth, where it disintegrates rapidly. This is primarily due to the use of superdisintegrants in the base FT formulation rather than the effervescent mix used in ETs and FMPs. This paper provides a detailed examination of the advantages and limitations of FMTs, ETs, and FTs, providing the first comprehensive review of these three dosage forms.</p>","PeriodicalId":18548,"journal":{"name":"Mini reviews in medicinal chemistry","volume":" ","pages":""},"PeriodicalIF":4.0,"publicationDate":"2026-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149012614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The majority of diabetes-related amputations are attributable to complications of diabetic wounds. In conditions characterized by impaired wound healing, macrophage polarization is dysregulated, primarily due to the persistence of M1 macrophages and a delayed switch to the reparative M2 phenotype. This article reviews the molecular, signalling, and epigenetic mechanisms that regulate macrophage function in diabetic wound healing. The key signalling pathways PI3K/AKT, NF-κB, and Notch play essential roles in determining the balance between inflammatory and reparative processes, whereas DNA methyltransferases, histone-modifying enzymes, and non-coding RNAs control the transcriptional programs that drive macrophages toward either the M1 inflammatory or the M2 reparative phenotype. This review examines how emodin and Astragalus Polysaccharides (APS) modulate these mechanisms to promote M2 polarization and reduce oxidative stress in diabetic wounds. Immunomodulatory hydrogels, extracellular vesicles, and genetargeted nanoparticles can deliver this reprogramming potential directly to the wound site; however, clinical translation remains difficult because macrophage phenotype shifts unpredictably in the in vivo wound environment, and no current platform achieves reliable targeted delivery to wound macrophages. Future research should combine such delivery vehicles with epigenetic and gene-editing tools to restore immune equilibrium and tissue regeneration.

Resistance arises through multiple interconnected mechanisms, including overexpression of ATP-binding cassette (ABC) transporters, activation of pro-survival signaling pathways, persistence of cancer stem cells (CSCs), epigenetic alterations, and protective interactions within the tumor microenvironment (TME). These mechanisms collectively reduce drug accumulation, promote tumor survival, and contribute to disease recurrence and treatment failure. Natural molecules have emerged as promising modulators of drug resistance because of their ability to simultaneously target multiple resistance pathways. Polyphenols, flavonoids, alkaloids, terpenoids, saponins, and marine-derived compounds have demonstrated the capacity to inhibit ABC transporters, suppress CSC-associated signaling, regulate apoptotic pathways, and remodel the TME. Structure-activity relationship studies have identified key molecular features, including planarity, lipophilicity, and specific substitution patterns, that influence transporter inhibition and resistance- modulating activity. Furthermore, natural compounds have shown synergistic effects with conventional anticancer agents, enhancing chemosensitivity and therapeutic efficacy in preclinical models. Despite encouraging experimental evidence, clinical translation remains challenging due to poor bioavailability, pharmacokinetic variability, limited clinical validation, potential herb-drug interactions, and batch-to-batch inconsistencies in natural product preparations. Advances in nanotechnology- based delivery systems, artificial intelligence-assisted drug design, and biomarker-guided precision medicine are providing new opportunities to overcome these limitations.

These molecules have demonstrated promising biological activities, including potent antibacterial and antifungal properties, significant inhibition of phosphodiesterase type 5 (PDE5), and other activities. Moreover, analogous molecules have shown potential applications as antioxidants, anti-inflammatory agents, antitumor compounds, regulators of the vasopressin receptor AVPR1b, among others.

Furthermore, this work identifies an existing research gap through the lack of systematic studies on the pyrazolo[3,4-e] isomer.
