The increase in drug-resistant , which has become resistant to existing standard-of-care agents, is a major concern, and new antibacterial agents are strongly needed. In this study, we introduced etamycin that showed an excellent activity against . We found that etamycin significantly inhibited the growth of wild-type strain, three subspecies, and clinical isolates in vitro and inhibited the growth of that resides in macrophages without cytotoxicity. Furthermore, the in vivo efficacy of etamycin in the zebrafish () infection model was greater than that of clarithromycin, which is recommended as the core agent for treating infections. Thus, we concluded that etamycin is a potential anti- candidate for further development as a clinical drug candidate.

Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive sarcomas and the primary cause of mortality in patients with neurofibromatosis type 1 (NF1). These malignancies develop within preexisting benign lesions called plexiform neurofibromas (PNs). PNs are solely driven by biallelic loss eliciting RAS pathway activation, and they respond favorably to MEK inhibitor therapy.

Purpose: Breast cancer ranks as the most prevalent cancer in women, characterized by heightened fatty acid synthesis and glycolytic activity. Fatty acid synthase (FASN) is prominently expressed in breast cancer cells, regulating fatty acid synthesis, thereby enhancing tumor growth and migration, and leading to radioresistance. This study aims to investigate how FASN inhibition affects cell proliferation, migration, and radioresistance in breast cancer, as well as the mechanisms involved.

MTDH-SND1 protein-protein interaction (PPI) plays an important role in the initiation and development of tumors, and it is a target for the treatment of breast cancer. In this study, we identified and synthesized a series of novel small-molecule inhibitors of MTDH-SND1 PPI. The representative compound showed potent activity against MTDH-SND1 PPI with an IC of 487 ± 99 nM and tight binding to the SND1-purified protein with a value of 279 ± 17 nM.
