Pd. Davis et al., BISINDOLYLMALEIMIDE INHIBITORS OF PROTEIN-KINASE-C - FURTHER CONFORMATIONAL RESTRICTION OF A TERTIARY AMINE SIDE-CHAIN, Bioorganic & medicinal chemistry letters, 4(11), 1994, pp. 1303-1308
A pharmacophore model for the localisation of the cationic binding sit
e of bisindolylmaleimide PKC inhibitors is described. This model has b
een used to guide selection of further conformationally restricted ter
tiary amine analogues, culminating in the identification and synthesis
of the potent and highly selective PKC inhibitor, Ro 32-0557.
