Currently, the synthesis of bioactive sulfonamides using amino acid as a starting reagent has become an area of research interest in organic chemistry. Over the years, an amine-sulfonyl chloride reaction has been adopted as a common step in traditional sulfonamide synthetic methods. However, recent developments have shown amino acids to be better precursors than amines in the synthesis of sulfonamides. Although amines and amino acids have some structural similarities, using amino acids rather than amines in the synthesis of sulfonamides minimizes several drawbacks. Comparatively, amino acids are preferred to amines as starting reagents in sulfonamide synthesis due to their biological relevance, chirality, stereochemistry, diversity of side chains, orthogonality in functional group manipulation, the potential for peptide and protein synthesis, mild reaction conditions, alignment with green chemistry principles, diverse synthetic applications, easy availability, and economic viability. Amino acids, having the aforementioned properties, offer a versatile platform for the synthesis of sulfonamides with tailored structures. The reaction mechanism of the synthesis of amino acid-derived sulfonamides involves a nucleophilic attack by the amino group on the activated sulfonyl species to produce a sulfonamide functional group. Amino acid-based sulfonamides have numerous pharmacological activities, including antibacterial, antiviral, anticancer, antioxidant, anti-inflammatory, anti-plasmodial, antimalarial, anti-trypanosomal, and insect growth regulatory properties. This review discusses several synthetic processes, emphasizing established ways, cutting- edge techniques, and novel approaches that emphasize the significance of amino acids in the synthesis of sulfonamides. The structure-activity relationship of amino acid-derived sulfonamides and their pharmacological activities are also highlighted.

Organic compounds containing azines, di-imines, or bis-Schiff-bases have two azomethine (-CH=N-) functional groups associated with a bridging component. These constituents have attracted attention from a diversity of disciplines, comprising coordination, medicinal, agriculture chemistry, and organic synthesis, because of their comprehensive chemical reactivity and nature. This study determines common synthetic approaches and various biological and pharmacological activities of several substituted bis-Schiff byproducts. The usefulness of bis-Schiff bases in synthetic chemistry and their potential as inhibitors of a number of enzymes have attracted research attention. We have examined different biological activities and common synthetic methods used to make bis- Schiff bases that have been published in the literature. A systematic search of the literature has been performed, and studies fitting the prearranged inclusion standards have been inspected. This review can open up new potentials for upcoming research in this area and advance our information on bis- Schiff bases.

Hydantoin, a five-membered heterocyclic scaffold, is regarded as a crucial scaffold in medicinal chemistry. Hydantoins have been useful in synthesizing medicines like nilutamide, enzalutamide, and apalutamide. Thiohydantoin and selenohydantoin have been discovered as two separate types of hydantoin. There are two hydrogen bond donors, two hydrogen bond acceptors, and four substitution sites. These characteristics have led to the design, synthesis, and expansion of hydantoin derivatives' biological and pharmacological effects against numerous types of malignancies. This study reviews the recent contributions of hydantoin and its isosteric variants to medicinal chemistry. To emphasize their significance, certain significant compounds based on hydantoins and their structure activity relationships (SAR) are briefly discussed. We thoroughly analyzed each scaffolds' structural characteristics and SAR, and these scaffolds may one day show potential anticancer activities.

Indole, a ubiquitous structural motif in bioactive compounds, has played a pivotal role in drug discovery. Among indole derivatives, indole-3-carboxaldehyde (I3A) has emerged as a particularly promising scaffold for the development of therapeutic agents. This review delves into the recent advancements in the chemical modification of I3A and its derivatives, highlighting their potential applications in various therapeutic areas. I3A derivatives have demonstrated a wide range of biological activities, including anti-inflammatory, anti-leishmanial, anti-cancer, anti-bacterial, antifungal, and anti-HIV properties. The structural modifications introduced to the I3A scaffold, such as substitutions on the indole ring (alkylation/arylation/halogenation), variations in the aldehyde group via condensation (Aldol/Claisen/Knoevenagel), and molecular hybridization with other reputable bioactive compounds like coumarins, chalcones, triazoles, and thiophenes, contribute to these activities. Beyond its therapeutic potential, I3A has also found applications as a ligand for Schiff base synthesis, a polymer, and a chromophore. This review provides a comprehensive overview of the latest research on I3A and its derivatives, focusing on the key reactions, modification pathways, reaction conditions, yields, and associated therapeutic activities. By understanding these advancements, researchers can gain valuable insights into the potential applications and future directions for I3A-based drug discovery.

Heterocyclic compounds are increasingly used in medicinal chemistry because they are the main components of many biological processes and materials. Benzimidazole remains the core center of the heterocyclic chemical group, with essential traits such as six-five-member connected rings and two nitrogen atoms at the 1,3 position in a six-membered benzene and five-membered imidazole- fused ring system. Molecules with benzimidazole derivatives serve important functions as therapeutic agents and have shown excellent results in clinical and biological research. In this comprehensive review, we summarize marketed medications that include the benzimidazole moiety. Here, we discuss two topics: PPIs and H1 receptor antagonists. Benzimidazole derivatives are important in all fields because they have the same isostructural pharmacophore as that of naturally occurring active biomolecules. While PPIs and H1 receptor antagonists are generally safe in the short term, accumulating data suggest that their long-term use may pose concerns. This systematic review aimed to assess global PPI use in the general population. This will help researchers, medicinal chemists, and pharmaceutical scientists to create breakthrough benzimidazole-based drugs. This review can help identify novel lead compounds and optimize existing benzimidazole derivatives to improve medicinal efficacy. Benzimidazole has attracted significant interest because of its high bioavailability, stability, and biological efficiency. This page reveals and discusses typical synthesis processes for marketed pharmaceuticals in the benzimidazole class of scaffolds, MOA, and therapeutic uses.

In recent years, there has been a growing emphasis on the "back-to-nature" movement, which has brought biopolymers derived from natural sources into the spotlight. These biopolymers are gaining attention for their versatile surface-active properties, anti-adhesive capabilities, excellent biocompatibility, non-toxicity, biodegradability, and antimicrobial effectiveness against a wide range of oral microorganisms, including both bacteria and fungi. Researchers have been actively modifying these eco-friendly, nature-based biopolymers to enhance their interaction with surrounding cells and tissues, improving their performance in vivo. This has led to innovative applications in areas such as surface coatings, controlled drug delivery, tissue repair, and dental implant devices. These advancements hold the potential to pave the way for the development of novel drug delivery systems with enhanced therapeutic properties, ultimately supporting the creation of innovative formulations for clinical use. This review aims to provide an up-to-date overview of recent developments, explore potential future directions, and highlight the promising applications of nature-derived biopolymers in oral healthcare.

Globally, one of the most prevalent cancers is colorectal cancer (CRC). Chemotherapy and surgery are two common conventional CRC therapies that are frequently ineffective and have serious adverse effects. Thus, there is a need for complementary and different therapeutic approaches. The use of microbial metabolites to trigger epigenetic alterations as a way of preventing CRC is one newly emerging field of inquiry. Small chemicals called microbial metabolites, which are made by microbes and capable of altering host cell behaviour, are created. Recent research has demonstrated that these metabolites can lead to epigenetic modifications such as histone modifications, DNA methylation, and non-coding RNA regulation, which can control gene expression and affect cellular behaviour. This review highlights the current knowledge on the epigenetic modification for cancer treatment, immunomodulatory and anti-carcinogenic attributes of microbial metabolites, gut epigenetic targeting system, and the role of dietary fibre and gut microbiota in cancer treatment. It also focuses on short-chain fatty acids, especially butyrates (which are generated by microbes), and their cancer treatment perspective, challenges, and limitations, as well as state-of-the-art research on microbial metabolites-induced epigenetic changes for CRC inhibition. In conclusion, the present work highlights the potential of microbial metabolites-induced epigenetic modifications as a novel therapeutic strategy for CRC suppression and guides future research directions in this dynamic field.

Alzheimer's Disease (AD) is a progressive neurodegenerative disorder that leads to cognitive decline and memory impairment. It is characterized by the accumulation of Amyloid-beta (Aβ) plaques, the abnormal phosphorylation of tau protein forming neurofibrillary tangles, and is often accompanied by neuroinflammation and oxidative stress, which contribute to neuronal loss and brain atrophy. At present, clinical anti-AD drugs are mostly single-target, improving the cognitive ability of AD patients, but failing to effectively slow down the progression of AD. Therefore, research on effective multi-target drugs for AD has become an urgent problem to address. The main derivatives of hydroxycinnamic acid, caffeic acid, and ferulic acid, are widely present in nature and have many pharmacological activities, such as antimicrobial, antioxidant, anti-inflammatory, neuroprotective, anti-Aβ deposition, and so on. The occurrence and development of AD are often accompanied by pathologies, such as oxidative stress, neuroinflammation, and Aβ deposition, suggesting that caffeic acid and ferulic acid can be used in the research on anti-AD drugs. Therefore, in this article, we have summarized the multi-target anti-AD derivatives based on caffeic acid and ferulic acid in recent years, and discussed the new design direction of cinnamic acid derivatives as backbone compounds. It is hoped that this review will provide some useful strategies for anti-AD drugs based on cinnamic acid derivatives.

It is hoped that this review will provide some useful strategies for anti-AD drugs based on cinnamic acid derivatives.</p>","PeriodicalId":18548,"journal":{"name":"Mini reviews in medicinal chemistry","volume":" ","pages":"163-175"},"PeriodicalIF":3.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142109289","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}
Essential oils (EOs) are a volatile mixture of bioactive compounds extracted from aromatic plants. The composition of EOs varies, which majorly depends on the extraction methods and plant parts. Aromatherapy using EOs has been reported for its several beneficial effects in humans. Aromatherapy is considered a complementary and/ or adjuvant therapeutic approach for treating several illnesses, especially to improve mental health and well-being. The incidence of sleep disorders, specifically insomnia, is nowadays increased, possibly due to urbanization and lifestyle. The studies showed that EOs-based treatments using lavender EO, bergamot EO, cinnamon EO, and rosemary EO (alone or in combinations) could improve sleep quality, duration, and deprivation in healthy subjects and patients, those who suffer from sleep-related issues. The current manuscript details the outcomes of EO-based treatments on the sleep quality of humans and the possible mechanisms associated with the health-promoting properties of EOs. Also, the toxicity and adverse effects of EOs have been discussed. The study indicated that EOs are potent adjuvant therapeutic candidates to manage mood-associated complications in humans. Moreover, the aromatherapeutic field requires detailed studies on toxicity and dose determination, which could provide safe and effective therapeutic results.
