Summary: Oxazolidinone derivatives are a potential new class of antimicrobial agents with activity against multidrug-resistant Gram-positive pathogens, but are associated with significant adverse events and emerging resistance. Hybridization of oxazolidinones with other antibacterial pharmacophores can interact with multiple targets or counterbalance known side effects.

Summary: This study developed a novel PLA-PEG NPs for the delivery of Linezolid against MRSA. The encapsulation efficiency of LNZ in PLA-PEG NPs was 15% with a 10:3 polymer to drug mass ratio, and sustained release kinetics with 65% of the antibiotic released within 80 h. The NPs exhibited antimicrobial activity against various Gram-positive bacteria including MRSA, and showed inhibitory activity on both planktonic growth and preformed biofilm of MRSA.

Summary: This study proposes a novel nanoplatform based on the autophagy cascade to overcome the obstacles in chemo-immunotherapy. The platform combines chemotherapy and starvation therapy to initiate pro-death autophagy and enhance antigen presentation, while also remodeling the immunosuppressive tumor microenvironment. Furthermore, the study discovers a new therapeutic direction for the respiration inhibitor 3-bromopyruvic acid (3BP) in cancer treatment. Overall, this study offers an opportunity to improve antitumor efficacy and boost immune responses.

Summary: Breast cancer is a common malignant tumor in women, and drug resistance remains a clinical challenge. In this study, a novel compound, G-5b, was developed with potent antagonistic and degradation activities comparable to the current drug fulvestrant. G-5b also showed improved stability and solubility. Mechanistically, G-5b engages the proteasome pathway to degrade ER, inhibiting the ER signaling pathway and inducing apoptosis and cell cycle arrest. In animal models, G-5b exhibited superior pharmacokinetics and pharmacodynamics properties. Overall, G-5b is a promising long-acting SERD worthy of further investigation and optimization.

Summary: A series of hybrid inhibitors combining pharmacophores of known kinase inhibitors and benzohydroxamate HDAC inhibitors were synthesized and evaluated for their anticancer activity and pharmacokinetic properties. Compounds 4d-f exhibited promising cytotoxicity against hematological cells and moderate activity against solid tumor models. Compound 4d showed potent inhibition of multiple kinase targets and had stable interactions with HDAC and members of the JAK family. These compounds showed selective cytotoxicity with minimal effects on non-tumorigenic cells and favorable pharmacokinetic profiles.
