This review summarizes progress and key advances reported over the past 5 years in the development of bioactive boron\u2010based heterocycles and related systems, including BN\u2010indoles, azaborines, benzoxazaborines, benzodiazaborines, benzoxaborinines, benzoxaboroles, and boronic acid derivatives. These motifs act as bioisosteres of carbon frameworks and impart distinct physicochemical properties such as increased polarity, improved solubility, and enhanced hydrogen\u2010bonding capabilities. Several examples highlight their therapeutic relevance. Azaborine\u2010based histone deacetylase (HDAC) inhibitors and BN\u2010indole derivatives show potent nanomolar enzyme inhibition. Benzoxaboroles have reached clinical relevance, including antifungal drugs such as tavaborole and crisaborole, as well as late\u2010stage candidates like epetraborole and acoziborole. Benzoxaborinines and olaparib isosteres exhibit activity against carbonic anhydrases and PARP enzymes, while boronic acid drugs such as bortezomib and ixazomib are established proteasome inhibitors used in cancer therapy. Additional applications include antiviral, antibacterial, antiparasitic, and anti\u2010inflammatory activities, for example Leishmania CPSF3 inhibitors and P2X7 receptor antagonists. Despite these advances, challenges remain regarding potency, pharmacokinetics, and mechanistic understanding of boron\u2013target interactions. Overall, boron\u2010based bioisosteres represent a versatile platform for developing new therapeutics across diverse disease areas.<\/jats:p>","DOI":"10.1002\/cmdc.70455","type":"journal-article","created":{"date-parts":[[2026,8,26]],"date-time":"2026-08-26T02:51:27Z","timestamp":1787712687000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Boron\u2010Based
