INDUSTRIAL APPLICATION FIELD The present invention relates to a novel compound that inhibits protein kinase C (hereinafter referred to as C-kinase) and has various pharmacological actions, and a method for producing the same. BACKGROUND OF THE INVENTION C-kinase is a protein kinase that is activated depending on phosphalipids and calcium, and is widely distributed in tissues and organs within the body. In recent years, it has become known that this enzyme plays an extremely important role in the cell membrane receptor and transmission mechanisms for many hormones and neurotransmitters. Examples of physiological reactions induced by such information transduction mechanisms involving C-kinase include serotonin release in platelets, lysosomal enzyme release and aggregation reactions, neutrophil superoxide production and lysosomal enzyme release, and adrenal medulla. Release of epinephrine from the kidneys, aldosterone secretion from the renal glomeruli, insulin secretion from the islets of Langerhans, histamine release from mast cells, acetylcholine release from the ileum, contraction of vascular smooth muscle, etc. have been reported. Furthermore, C-kinase is thought to be involved in cell proliferation and carcinogenesis [References: Y. Nishizuka, Science, 225 ,

Cyclic Nucleotide and Protein
Phosphorylation Research, Vol.18, P159,
edited by P.Greengard and GARobison,
Raven Press, New York, 1984]. In this way, it has become clear that this enzyme is involved in many important physiological reactions and various pathological conditions within the body. Therefore,
If C-kinase activity can be artificially inhibited by using its specific inhibitor, it is thought that it will be possible to prevent and treat a wide variety of diseases of the circulatory system, inflammation, allergies, tumors, and the like. On the other hand, antipsychotic drugs such as trifluoperazine and chloropromazine, dibenamine and tetracaine known as local anesthetics, and the calmodilin inhibitor W-7 [N-(6-aminohexyl)-5-
Although it has been found that drugs such as chloro-1-maphthalenesulfonamide have C-kinase inhibitory activity, the C-kinase inhibitory effect is not the main effect of each drug and has low specificity, and Activity is also low [Y. Nishizuka et al., J. Biol.
Chem., 255 , 8378 (1980); RCSchatzman et
al., Biochem.Biophys.Res.Commun., 98 , 669
(1981); BCWise et al., J.Biol.Chem., 257 ,
8489 (1982)]. On the other hand, there are applications for K-252 and KT-5556 represented by the following formulas, and the applications for K-252 have already been published (Japanese Patent Application Laid-Open No. 60-41489, JP-A No. 60-17531). K-252: R A = CH 3 , R B = H KT-5556: R A = H, R B = H K-252 has antihistamine-releasing action and anti-allergic action in JP-A-60-41489. is listed. Recently, a compound presumed to be the same as K-252 and KT-5556 was reported as an antibacterial substance [M. Senzaki et al., J. Antibiotics, 38
(10), 1437 (1985)]. In this document, R A =
CH 3 , R B = AC NO compounds are also disclosed. Furthermore, Staurosporine, which has the following structure and has an antibacterial effect, is known as a compound with a structure relatively similar to that of K-252 [S.Omura et al.
al., J. Antibiotics, 30 (4), 275 (1977), A.
Furusaki et al., J.Chem.Soc.Chem.Commun.
800 (1978)]. Problems to be Solved by the Invention K-252 and KT-5556 also have C-kinase inhibitory activity, but in order to search for a compound with better C-kinase inhibitory activity, a K-252 derivative was created. Means for solving the problems The present invention is based on the formula [] {wherein R is hydrogen, lower alkyl, aralkyl, or acyl. Y is OR 1 (wherein R 1 is selected from hydrogen, lower alkyl and aralkyl. However, when R is hydrogen, R 1 is not hydrogen or methyl; when R is acetyl, R 1 is not methyl. ),or

(7) is synthesized by the following steps. [Step 6] Compound (7) can be obtained by alkali hydrolysis of compound (6) (6-1) in which R is acyl. The reaction is carried out in a mixed solvent of water and an alcohol such as methanol or ethanol, using 1.5 to 3 equivalents of sodium hydroxide or potassium hydroxide based on compound (6-1).
The reaction is usually carried out at room temperature and is completed within several hours. Examples Examples and experimental examples of the present invention are shown below. Example 1 O-methyl-methyl ester (1a) A solution of K-252, 184 mg (0.4 mmol) in DMF (2 ml) was cooled on ice, and 19.2 mg of 50% oily sodium hydride was added.
(0.4 mmol) was added. After 20 minutes, methyl iodide
25 μl (0.4 mmol) was added, and the mixture was further stirred for 1 hour.
20 ml of chloroform was added to the reaction mixture, and the solution was washed with water and dried over anhydrous sodium sulfate. The residue obtained by removing the solvent under reduced pressure was purified by silica gel column chromatography (chloroform) to obtain 65 mg (34%) of 1a as a pale yellow powder. ○Melting point 250-252℃ (recrystallized from CH2Cl2 - CH3OH ) ○1H-NMR ( CDCl3 ) δ9.42 (d, 1H , J=8

Add 10ml of 3N sodium hydroxide aqueous solution to the solution,
Stir overnight at room temperature. The solvent in the reaction mixture was removed under reduced pressure, and 50 ml of 1N hydrochloric acid was added to the residue, followed by stirring.
Insoluble matter was removed and washed with 1N hydrochloric acid and then with methanol. It was dried under reduced pressure to obtain 9.83 g (87%) of carboxyl compound [1B] as a pale yellow powder. Add 1.42 ml (15 mmol) of acetic anhydride to a solution of 4.53 g (10 mmol) of compound [1B] in anhydrous pyridine (50 ml).
was added and stirred at room temperature for 1 hour. The solvent in the reaction mixture was removed under reduced pressure, and 50 ml of 1N hydrochloric acid was added to the residue and stirred. Insoluble matter was removed and washed with 1N hydrochloric acid and then with water. Drying under reduced pressure gave 4.79 g (97%) of 3a as a pale yellow powder. ○Melting point 267-270℃ ○1H-NMR (DMSO-d 6 + CDCl 3 ) δ9.36 (d,

The concentration of the test compound was varied, and the compound concentration that inhibited the enzyme activity by 50% (IC 50 ) was determined. The results are shown in Table 1.

Heparin) was injected intraperitoneally at 6 ml/animal.
After 2 minutes of abdominal surgery, the abdomen was opened and intraperitoneal exudate was collected. The exudate collected from 6 animals was heated to 4°C.
After centrifugation at 100 x g for 5 minutes, pour an appropriate amount of cooling water onto the sediment.
After adding MCM and washing three times, a cell suspension (abbreviated as peritoneal exudate cells PEC) was finally prepared so that the number of mast cells was about 3 x 104 cells/ml. Note that mast cells were identified by staining intracellular granules with 0.05% toluidine blue. After pre-incubating 1 ml of the PEC obtained in this way at 37°C for 10 minutes, 0.1 ml of test drug solutions of various concentrations were added and incubated for 10 minutes. 0.1 ml was added and incubated for an additional 15 minutes. After adding 3 ml of ice-cold physiological saline to stop the reaction, 4℃, 1100×
The supernatant and precipitate were obtained by centrifugation at g for 10 minutes. The amount of histamine in the supernatant and sediment was measured by a fluorescence method according to Komatsu's method [Allergy 27 , 67 (1978)]. Histamine release rate was expressed as a percentage of the amount of histamine in the supernatant relative to the total amount of histamine in the cells. In addition, the histamine release inhibition rate of the test drug solution was calculated using the following formula. Release inhibition rate (%) = (1 - histamine release in the presence of drug - spontaneous release / histamine release in the absence of drug - spontaneous release) x 100 By changing the concentration of the test compound, histamine release was reduced to 50
The compound concentration (IC 50 ) that inhibits the results by % was determined. The results are shown in Table 2. Table 2 Synthetic compounds that inhibit histamine release Compound IC 50 , ng/ml 4b 290 6f 76 Effects of the invention The compound [ ] and its salts have a C-kinase inhibitory effect and are widely used to treat diseases of the circulatory system, inflammation, etc. It has the potential to be used for the prevention and treatment of allergies, tumors, etc.
