摘要
(Chemical Equation Presented) The carborane framework gives analogues able to induce 20S proteasome activities. A series of ortho-carboranylphenoxy derivatives were synthesized as 20S proteasome agonists, and carborane derivatives 11 a and 11 b were found to be potent inducers of the β1 and β2 activities of the 20S proteasome. Since small-molecule proteasome activators have not been developed, the carboranes described here have potential as chemical probes for the investigation of proteasome-dependent degradation pathways. © 2010 Wiley-VCH Verlag GmbH& Co.
