    $34,911.70 - $121,647.00
    Butyrolactone I is one of a family of three butyrolactones isolated from Aspergillus fumigatus, first reported in 1983. Butyrolactone I is a selective inhibitor of cyclin-dependent kinases CDK1/cyclin B, CDK2 and CDK5, and is an important bioprobe for understanding the cellular roles of CDKs.

    Butyrolactone I is soluble in ethanol, methanol, DMF and DMSO.
    Mechanism of ActionButyrolactone I inhibits the cell cycle at the G1/S and G2/M transitions.
