摘要：
In this study, we describe the combined effects of bedaquiline (BDQ) and the natural product curcumin (CUR) on Mycobacterium abscessus. In both in vitro and in vivo experiments, CUR enhanced BDQ's inhibitory effect. This combination reduced M. abscessus survival under nutrient-deprived, hypoxic, and acidic conditions, accelerated ATP depletion, mitigated BDQ-induced respiratory compensation, and effectively improved infection outcomes in both normal and immunosuppressed mice. Metabolomics analysis revealed that adding CUR to BDQ exacerbated BDQ-dependent downregulation of purine and pyrimidine metabolism and amino acid synthesis. Thus, BDQ-CUR combination therapy could potentially be applied to treat M. abscessus infections.
