Summary: A new tetracyclic ring system with strong antiproliferative activity towards several haematological cell lines has been identified through a multistep sequence. These compounds exhibit high activity in cell lines expressing the mutant FLT3/ITD, potentially inhibiting FLT3 kinase. Molecular modelling and Molecular Dynamics simulation support the mechanism of action, with compound 9c reducing phosphorylation of FLT3 and downstream targets, leading to cell cycle arrest and apoptosis. In a mouse model, compound 9c significantly reduces tumor growth without obvious toxicity.

Summary: Antibiotic resistance is a major threat to public health, with Gram-negative bacteria presenting unique challenges due to their low permeability and efflux pumps. Limited understanding of the chemical rules for overcoming these barriers hinders antibacterial drug discovery. Efforts to address this issue, such as screening compound libraries and using cheminformatic analysis, have led to the design of sulfamidoadenosines with diverse substituents, showing potential utility in accumulation in Escherichia coli.
