Structure of the catalytic domain of human protein kinase C beta II complexed with a bisindolylmaleimide inhibitor.[Pubmed:17115692]

Biochemistry. 2006 Nov 28;45(47):13970-81.

The conventional protein kinase C isoform, PKCII, is a signaling kinase activated during the hyperglycemic state and has been associated with the development of microvascular abnormalities associated with diabetes. PKCII, therefore, has been identified as a therapeutic target where inhibitors of its kinase activity are being pursued for treatment of microvascular-related diabetic complications. In this report, we describe the crystal structure of the catalytic domain of PKCbetaII complexed with an inhibitor at 2.6 A resolution. The kinase domain of PKCbetaII was cleaved and purified from full-length PKCbetaII expressed in baculovirus-infected insect cells. The overall kinase domain structure follows the classical bilobal fold and is in its fully activated conformation with three well-defined phosphorylated residues: Thr-500, Thr-641, and Ser-660. Different from the crystal structures of nonconventional PKC isoforms, the C-terminus of the PKCbetaII catalytic domain is almost fully ordered and features a novel alpha helix in the turn motif. An ATP-competitive inhibitor, 2-methyl-1H-indol-3-yl-BIM-1, was crystallized with the PKCbetaII catalytic domain as a dimer of two enzyme-inhibitor complexes. The bound inhibitor adopts a nonplanar conformation in the ATP-binding site, with the kinase domain taking on an intermediate, open conformation. This PKCbetaII-inhibitor complex represents the first structural description of any conventional PKC kinase domain. Given the pathogenic role of PKCbetaII in the development of diabetic complications, this structure can serve as a template for the rational design of inhibitors as potential therapeutic agents.

Transcriptional activity of the hamster CYP11B2 promoter in NCI-H295 cells stimulated by angiotensin II, potassium, forskolin and bisindolylmaleimide.[Pubmed:9584833]

J Mol Endocrinol. 1998 Apr;20(2):183-91.

We studied the regulation of the hamster CYP11B2 gene in the NCI-H295 cell line, which is known to produce aldosterone in response to stimulation by angiotensin II (AII) and KCl. Ten deletion plasmids harboring the 5'-untranslated region of the CYP11B2 gene were used for chloramphenicol acetyltransferase (CAT) assays. Transient transfections showed progressively increasing basal promoter activity by constructs beyond the TATA box, with a peak occurring with the -167 bp construct which contains putative Adl, Ad2, Ad5 and the newly reported -143/-161 cis-element sequences. The promoter activity was lower with the construct containing the putative Ad3 cis-element and increased with longer constructs. This indicates the presence of both inhibitory and stimulatory cis-elements in this area of the gene. Expression of the reporter gene of all constructs was stimulated by AII and KCl, with the exception of the construct containing only the TATA box, which showed 6-fold and 10-fold increases occurring with the -167 bp deletion plasmid. The patterns of increase in CAT activity with AII and KCI treatment were similar, showing that these two regulators can stimulate hamster CYP11B2 promoter activity through common cis-elements. The calcium channel antagonist nifedipine blocked the stimulatory effects of KCl on CAT activity, showing the involvement of calcium channels in the regulation of CYP11B2 gene transcription by KCl. 12-O-Tetradecanoylphorbol 13-acetate, a known stimulator of the protein kinase C (PKC) signaling pathway, was without significant effect on CAT activity. Bisindolylmaleimide, a specific inhibitor of PKC, had a significant enhancing effect (3.4- to 6-fold), indicating that PKC may negatively regulate the expression of the hamster CYP11B2 gene in NCI-H295 cells. A mutation was induced in the sequence -143/-161 of the - 350 bp construct in order to determine its importance in the regulation of hamster CYP11B2 promoter activity. The stimulatory effects of AII, KCl, forskolin and bisindolylmaleimide on CAT activity were significantly less in the mutant than in the wild type. These results confirm that this cis-element is necessary in maintaining a high level of transcriptional activity in stimulated NCI-295H cells. In conclusion, using NCI-295H transfected cells, we have found that the 5'-untranslated region of the hamster CYP11B2 gene possesses transcriptional activity with stimulatory and also inhibitory cis-elements; CYP11B2 promoter activity can be stimulated by AII, KCl, forskolin, dibutyryl cAMP and bisindolylmaleimide. Our results suggest that this gene is positively regulated through the protein kinase A signaling pathway and through calcium channels, whereas PKC may have a negative regulatory effect upon the transcription of the CYP11B2 gene. Furthermore, we have shown that the cis-element -143/-161 in the 5'-untranslated region of the hamster CYP11B2 gene is important in maintaining a high level of promoter activity in stimulated NCI-295H cells.

Chromaffin cell catecholamine secretion: bisindolylmaleimide compounds exhibit novel and potent antagonist effects at the nicotinic cholinergic receptor in pheochromocytoma cells.[Pubmed:12021395]

Mol Pharmacol. 2002 Jun;61(6):1340-7.

Activation of protein kinase C (PKC) stimulates nicotine-induced catecholamine secretion. PKC down-regulation by prolonged pretreatment with phorbol 12-myristate 13-acetate diminished nicotine-induced catecholamine secretion only slightly (approximately 16%), suggesting substantial PKC independence of nicotinic receptor activation. However, we found that bisindolylmaleimide compounds (which are also putative PKC chemical inhibitors) dramatically inhibited nicotine-induced catecholamine secretion (IC(50) values of approximately 24-37 nM). This inhibition was specific for the nicotinic cholinergic receptor. Catecholamine secretion induced by other nicotinic agonists (such as epibatidine, anatoxin, or cytisine) was also powerfully antagonized by Bisindolylmaleimide II (IC(50) values of approximately 60-90 nM). Even high-dose nicotinic agonists failed to overcome the inhibition by Bisindolylmaleimide II, suggesting noncompetitive nicotinic antagonism by this class of compounds. Nicotinic inhibition by bisindolylmaleimide seemed not to be readily reversible. Structure-activity studies of bisindolylmaleimide compounds revealed that bisindolylmaleimides I through III are the most potent nicotinic antagonists at the nicotinic cholinergic receptor in PC-12 cells (IC(50) < or =37 nM), whereas bisindolylmaleimide IV and V have far less nicotinic antagonist activity (IC(50) >1 microM); the active compounds I through III have cationic tails at an indole nitrogen, whereas the least potent compounds IV and V do not. By contrast, a free NH within the maleimide ring is crucial for PKC inhibition by this class of compounds. We conclude that bisindolylmaleimides I through III are some of the most potent noncompetitive neuronal nicotinic antagonists, indeed the most potent such antagonists we have observed in PC-12 cells. Nicotinic antagonism of these compounds seems to be independent of PKC inhibition.

The bisindolylmaleimide GF 109203X is a potent and selective inhibitor of protein kinase C.[Pubmed:1874734]

J Biol Chem. 1991 Aug 25;266(24):15771-81.

Staurosporine is the most potent inhibitor of protein kinase C (PKC) described in the literature with a half-maximal inhibitory concentration (IC50) of 10 nM. Nevertheless, this natural product is poorly selective when assayed against other protein kinases. In order to obtain specific PKC inhibitors, a series of bisindolylmaleimides has been synthesized. Structure-activity relationship studies allowed the determination of the substructure responsible for conferring high potency and lack of selectivity in the staurosporine molecule. Several aminoalkyl bisindolylmaleimides were found to be potent and selective PKC inhibitors (IC50 values from 5 to 70 nM). Among these compounds GF 109203X has been chosen for further studies aiming at the characterization of this chemical family. GF 109203X was a competitive inhibitor with respect to ATP (Ki = 14 +/- 3 NM) and displayed high selectivity for PKC as compared to five different protein kinases. We further determined the potency and specificity of GF 109203X in two cellular models: human platelets and Swiss 3T3 fibroblasts. GF 109203X efficiently prevented PKC-mediated phosphorylations of an Mr = 47,000 protein in platelets and of an Mr = 80,000 protein in Swiss 3T3 cells. In contrast, in the same models, the PKC inhibitor failed to prevent PKC-independent phosphorylations. GF 109203X inhibited collagen- and alpha-thrombin-induced platelet aggregation as well as collagen-triggered ATP secretion. However, ADP-dependent reversible aggregation was not modified. In Swiss 3T3 fibroblasts, GF 109203X reversed the inhibition of epidermal growth factor binding induced by phorbol 12,13-dibutyrate and prevented [3H] thymidine incorporation into DNA, only when this was elicited by growth promoting agents which activate PKC. Our results illustrate the potential of GF 109203X as a tool for studying the involvement of PKC in signal transduction pathways.
