To match the current needs of the community, industries and in particular chemical industry is looking for novel and cheap strategies that have less adverse effects on the environment. Heterocyclic compounds are one particular motif, which is prevalent in nature. It is found in a wide range of synthetic and natural compounds, both established and in development as potent therapeutic candidates. According to the US retail market in 2014-2015, heterocyclic moieties constitute the basic skeletons for 80% of marketed pharmaceuticals. However, majority of the synthetic methodologies still uses classical approaches with toxic solvents, stoichiometric reagents, reactions with less atom economy etc. Thus, there is an urgent need for green, sustainable alternatives of the classical reactions. In recent years, an array of diverse approaches and technologies have been discovered by the scientific community to address the issue of eco-friendly manufacture of various pharmaceutically and medicinally important heterocyclic molecules. In this context, the current review will summarize various reported green pathways to the heterocyclic architecture, particularly O, N, and S-heterocyclic compounds. The methods highlighted in this article includes reaction in environment friendly nonconventional media, solvent-free approaches, heterogeneous catalysis, organocatalysis, electrochemical reactions, microwave-mediated reactions, ultrasound-based reactions, enzymatic reactions, biocatalysis, and others.</p>","PeriodicalId":18548,"journal":{"name":"Mini reviews in medicinal chemistry","volume":" ","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143008279","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}

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.

The effectiveness of PDT primarily relies on the quality of the photosensitizers employed. When exposed to appropriate light irradiation, these photosensitizers absorb energy and transition to an excited state, eventually transferring energy to nearby molecules and generating Reactive Oxygen Species (ROS), including singlet oxygen [<sup>1</sup>O<sub>2</sub>]. The ability to absorb light in visible and nearinfrared wavelengths makes porphyrins and derivatives useful photosensitizers for PDT. Chemically, Porphyrins, composed of tetra-pyrrole structures connected by four methylene groups, represent the typical photosensitizers. The limited water solubility and bio-stability of porphyrin photosensitizers and their non-specific tumor-targeting properties hinder PDT effectiveness and clinical applications. Therefore, a wide range of modification and functionalization techniques have been used to maximize PDT efficiency and develop multidimensional porphyrin-based functional materials. Recent progress in porphyrin-based functional materials has been investigated in this review paper, focusing on two main aspects including the development of porphyrinic amphiphiles that improve water solubility and biocompatibility, and the design of porphyrin-based polymers, including block copolymers with covalent bonds and supramolecular polymers with noncovalent bonds, which provide versatile platforms for PDT applications. The development of porphyrin-based functional materials will allow researchers to significantly expand PDT applications for cancer therapy by opening up new opportunities. With these innovations, porphyrins will overcome their limitations and push PDT to the forefront of cancer treatment options.</p>","PeriodicalId":18548,"journal":{"name":"Mini reviews in medicinal chemistry","volume":" ","pages":"259-276"},"PeriodicalIF":3.3,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142372308","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}

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.

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.
