activity, is obtained. Besides indole substituents, which were used for the synthesis of staurosporinone, substituted indole-, phenyl-, and pyridyl- as well as enantiomerically pure (S)-proline derivatives were used. Here, considerably high diastereoselectivity and enantioselectivity ((S)-pyrrolidine) could be detected. Just like the total synthesis of staurosporinone within three steps, the easiest and shortest

The design and synthesis of a series of novel inhibitors of protein kinase C (PKC) is described. These 2,3-bisarylznaleimides were derived from the structural lead provided by the indolocarbazoles, staurosporine and K252a. Optimum activity required the imide NH, both carbonyl groups, and the olefinic bond of the maleimide ring. 2,3-Bisindolylmaleimides were the most active, and the potency of these was improved by a chloro substituent at the 5-position of one indole ring (compound 28, IC50 0.11-mu-M). In a series of (phenylindolyl)maleimides, nitro compound 74 was most active (IC50 0.67-mu-M). Naphthalene 19 and benzothiophene 21 showed greater than 100-fold selectivity for inhibition of PKC over the closely related cAMP-dependent protein kinase (PKA).
