Notable optimization strategies included the strategic use of five- and sixmembered nitrogen-containing heterocycles as cyclic bioisosteres and solubilizing groups. For the kinase inhibitor golidocitinib, the unique position of a solubilizing group within the binding pocket achieved dual benefits, i.e., enhanced target selectivity and physicochemical properties. When developing central nervous system-penetrant drugs such as zorifertinib, careful control of rotatable bonds, hydrogen bond donors, and molecular lipophilicity was critical for optimizing blood-brain barrier penetration while remaining suitable for oral administration.

However, its non-selective action can cause serious side effects that negate the therapeutic benefits. Efforts have thus been made to identify pharmacological agents that can selectively protect normal tissues from exposure to ionizing radiation. Seven decades of study, however, have shown that the desired success has not been achieved in obtaining an ideal radioprotective agent. Moreover, even at optimal doses, the FDA-approved drug, amifostine (also known as WR-2721 [S-2- (3-aminopropyl-amino) ethyl phosphorothioic acid], exhibits significant toxicity. An ideal radioprotective agent can also be beneficial in environments where individuals are exposed to prolonged, low-dose radiation. Considering this, there is a pressing need to develop methods of shielding cells and patients from the deleterious effects of radiation, and a non-toxic radioprotective drug can be useful in both clinical and occupational contexts. Studies have shown that the fruits of Emblica officinalis and its cardinal phytochemicals, such as gallic acid, ellagic acid, quercetin, geraniin, corilagin, and kaempferol, have been demonstrated to mitigate radiationinduced side effects. Research has also demonstrated that fruits can reduce the severity of radiationinduced mucositis in head and neck cancer patients undergoing curative treatment. Currently, there are no clinically effective non-toxic medications that are beneficial in mitigating radiation-induced ill effects. In lieu of this, for the first time, this review compiles the positive effects of fruits, phytochemicals, and their byproducts, chyawanprash and triphala, on radiation-induced damage, the mechanisms by which these effects occur, and the gaps that must be filled in order for future research to help people and the agricultural and nutraceutical industries.</p>","PeriodicalId":18548,"journal":{"name":"Mini reviews in medicinal chemistry","volume":" ","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144675266","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 past 10 years, we have witnessed intense research activity on the biological potential of human monoamine oxidase (hMAO) inhibitors that have been associated with the prevention of oxidative stress and inflammation. These inhibitors have emerged as promising therapeutic agents, especially in the treatment of neurodegenerative diseases (NDs), where their core activity may help mitigate disease progression. An overview of the current state of numerous scaffolds, such as chromones, coumarins, chalcones, propargylamines, benzothiazoles, aminoisoquinolines, and the natural compounds, including ferulic acid, resveratrol, and chrysin, which combine antioxidant capability and hMAO inhibition is given in this review, with particular attention given to each scaffold's mechanism of action and structure-activity relationships (SARs), which are thoroughly discussed. Focusing on the dual mechanism of action, combining inhibition and antioxidant properties, as a potential therapy for neurodegenerative diseases, we have reviewed the different chemical classes of multi-targetdirected ligand (MTDL) inhibitors developed within this framework. Other central nervous system (CNS)-related enzymes, such as cholinesterases, carbonic anhydrases, and BACE-1, have also been explored as targets in the MTDL strategy. By understanding their biological activity, medicinal chemists can better comprehend biological activity and recommend more effective and specific ND treatments.</p>","PeriodicalId":18548,"journal":{"name":"Mini reviews in medicinal chemistry","volume":" ","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144600965","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}
