2-Acetylfuran

2-Acetylfuran (CAS No.: 1192-62-7) is a furan-derived small molecule widely utilized as a versatile intermediate and fragment scaffold in biomedical research and drug discovery. It can be obtained from natural sources or generated through Maillard-type reactions between reducing sugars and amino acids, and its heterocyclic framework supports diverse chemical modifications for structure–activity relationship exploration. In pharmaceutical research contexts, it serves as a key building block in the synthesis of β-lactam antibiotic intermediates, including those related to cefuroxime, and its derivatives have been investigated as foundational motifs in the development of compounds with antiparasitic activity, such as those targeting amoebic organisms. Although it is not associated with a single well-defined biological target, 2-acetylfuran functions as a reactive scaffold enabling the generation of libraries that can be screened against enzymatic pathways or microbial systems, with observed bioactivities of derived compounds often falling within the nanomolar to micromolar range depending on structural elaboration. It is commonly applied in early-stage drug design, fragment-based screening, and synthetic route development, as well as in vitro assays and exploratory studies in cell-based or biochemical models, where experimental concentrations vary according to specific assay requirements and optimization strategies.
