Inhibitors of protein kinase C (PKC)α, PKCδ and PKCζ are provided which are selective for those PKC isotypes. Combinatorial libraries for identifying protein kinases are also provided, as are methods of identifying protein kinases using those libraries. Additionally, methods of treating a mammal having a deleterious condition, where the condition is dependent on a protein kinase for induction or severity, are provided. Methods of inhibiting protein kinases are also provided.
A new stereoselective synthesis of (+)-taxodione () from (−)-abietic acid () via the iron carbonyl complex is described.
