Source of validity: Scientific
Rating (out of 5): 4

Boronic acid analogues are scientifically validated as effective agents, particularly as alternatives or adjuncts to traditional antibiotics. Their primary mechanism involves the inhibition of serine β-lactamases, which are enzymes produced by certain bacteria to resist β-lactam antibiotics (such as penicillins and cephalosporins). Notably, the boronic acid-based compound vaborbactam, in combination with meropenem, has been approved for clinical use and demonstrates potent activity against carbapenem-resistant Enterobacteriaceae (CRE). The scientific justification for their use is robust; multiple peer-reviewed studies have shown that boronic acid derivatives can restore the efficacy of β-lactam antibiotics against resistant bacterial strains. They act as reversible, covalent inhibitors of the active site serine in β-lactamases, thereby protecting the antibiotic from degradation. While boronic acids themselves are not typically used as standalone antibiotics, their role as β-lactamase inhibitors is well established and supported by preclinical, clinical, and pharmacological evidence. As resistance to conventional antibiotics rises, boronic acid analogues represent a key innovation in antibiotic adjuvant therapy, with ongoing research exploring their utility against a broader spectrum of bacterial enzymes and pathogens.
