10,11-Dehydrocurvularin (CAS 1095588-70-7)

10,11-Dehydrocurvularin, cataloged under CAS number 1095588-70-7, is a structural analog of curvularin, a macrocyclic lactone with notable biological properties. This compound features a distinctive modification: the removal of a hydrogen atom to introduce a double bond between the 10th and 11th carbon atoms in the lactone ring, enhancing its biochemical activity. 10,11-Dehydrocurvularin acts primarily by interfering with the cell cycle of fungi and possibly other cells by inhibiting proper spindle formation during mitosis. This disruption prevents the chromosomes from aligning and segregating correctly during cell division, leading to cell cycle arrest and potentially cell death. In research contexts, 10,11-Dehydrocurvularin is particularly valuable for studying the mechanisms of cell division and mitotic regulation. It provides insights into how alterations in the molecular structure of such compounds affect their interaction with biological targets involved in critical cellular processes. Researchers employ this compound to probe the dynamics of spindle assembly and to understand the pathways that regulate cell cycle progression in various organisms. These investigations help delineate the fundamental aspects of cell biology and contribute to the broader field of molecular biology by elucidating how natural substances can influence complex cellular functions.
