A novel A-77 compound of this invention is advantageously produced by cultivating the strain AI-77 mentioned above, but it can also be obtained as an isolate from the culture of other A-77 compound-producing microorganisms that belong to Bacillus. Common knowledge about the cultivation of microorganisms of Bacillus can be relied upon in the cultivation of the strain AI-77 and other A-77 compound-producing microorganisms of Bacillus. To be more specific, these microorganisms are cultivated aerobically about at 25.degree. to 40.degree. C. on a medium containing a nitrogen source, carbon source, inorganic salt, vitamin, amino acid, nucleic acid related substance and any other substance that is necessary for the growth of such microorganisms. Large-scale cultivation is advantageously performed under aeration agitation.
The mycological properties of strain AI-77 (FERM. P No. 4066, ATCC No. 31650) are indicated below:
Mycological Properties
(a) Nature of growth on the following various media:
(1) Bouillon: The medium becomes practically turbid throughout and forms no film.
(2) Bouillon agar plate culture: The colony is generally smooth, and sometimes a rough flat colony is formed. Opaque to translucent. First ivory, then white, finally cream-colored. No pigment is formed.
(3) Glucose bouillon agar medium: The microorganism grows better on this medium than on bouillon agar medium. The appearance of the colony is the same as on bouillon agar medium.
(4) Gelatin medium: Gelatin liquefies gradually.
(5) Peptone water: The growth of microorganism is slightly inhibited and the medium becomes slightly turbid.
(6) Litmus milk: The microorganism does not coagulates or peptonize milk. There is observed no change in litmus.
(7) Potato medium: The microorganism spreads in a tawny colony with small wrinkles.
The morphological properties of the microorganism on a glucose bouillon agar medium are such that the cell is a short rod 0.5.about.0.9.times.0.5.about.2.0.mu. in size, Gram variable, and forms elliptical to cylindrical shaped spores which are generally positioned in the center of the cell and whose sides do not appreciably bulge outward.
(b) Physiological properties
(1) Optimum growth conditions: pH 5 to 8, 27.degree. to 35.degree. C., aerobic
(2) Growth conditions: pH 5.0 to 10.0, 10.degree. to 55.degree. C.
(3) Gram staining: variable
(4) Acid resistance: none
(5) Methyl Red test: positive
(6) Voges-Proskauer reaction: positive
(7) Formation of indole not observed
(8) Formation of hydrogen sulfide little observed.
(9) Formation of ammonia not observed.
(10) Reduction of nitrate salt not observed.
(11) Formation of catalase is active.
(12) Gradually liquefies gelatin.
(13) Does not hydrolyze starch.
(14) Utilizes citric acid.
(15) Grows on 7% NaCl medium.
(16) Does not reduce methylene blue.
(17) Utilizes urea very slightly.
(c) Utilization of carbon sources
The microorganism forms an acid by utilizing fructose, saccharose, glucose and mannitol. It slightly utilizes mannose and trehalose to form an acid. It does not utilize arabinose, xylose, galactose, lactose, maltose, raffinose, sorbitol, inositol, glycerol, .alpha.-methylglycoside, inulin, dextrin, starch or cellulose. Neither carbon source generates a detectable gas.
Checking the above described properties against Bergey's Manual of Determinative Bacteriology, 7th and 8th Eds. shows that the microorganism under discussion has properties that generally agree with those of Bacillus pumilus in spite of a few differences (e.g. it does not form an acid from arabinose or xylose, or it does not peptonize or coagulate milk). Therefore the microorganism has been identified as a strain that belongs to Bacillus pumilus, and named it Bacillus pumilus AI-77 in the absence of a known strain indentical with it. The microorgansim has been deposited with the Fermentation Research Institute, Agency of Industrial Science and Technology, Japan, under FERM P No. 4066 on May 20, 1977, and also has been deposited with American Type Culture Collection, U.S.A., as ATCC No. 31650 on June 16, 1980. All natural and artificial variants of Bacillus pumilus AI-77 that have the ability to produce AI-77 compounds can be used in this invention.
The production of Compounds A to G by cultivation and their recovery from the culture are performed with the specific means that will be described hereunder. When A- to G-producing microorganisms are cultivated aerobically for a period of time on a liquid medium containing nutrient sources required by the microorganisms, compounds A to G are accumulated in the culture. The compounds are recovered from the culture with combinations of purifying means that utilize the physicochemical properties of the compounds. Nutrient sources used in the fermentation are carbon sources, nitrogen sources, inorganic salts, as well as vitamins and amino acids (optional) and other nutrient elements necessary for the growth of the microorganism used. Examples of the carbon source are glucose, sucrose, fructose, mannitol, organic acid, molasses, starch and glycerin. Examples of the nitrogen source are corn steep liquor, soybean meal, pharmamedia, yeast extract, meat extract, protein hydrolyzates such as peptone and Casamino acid, amino acid and ammonium salt. Examples of the inorganic salt are those that contain metal ions such as sodium, potassium, calcium, magnesium and iron, as well as ion-containing salts of ammonia, phosphoric acid, sulfuric acid, hydrochloric acid, carboxylic acid, etc. The medium must also contain essential nutrient elements necessary for the growth of the microorganism concerned. Vitamins, amino acids and nucleic acid related elements are incorporated in the medium as required. AI-77 compound-producing microorganisms grow under various conditions. For example, they are capable of growing on a variety of media having a wide range of initial pHs. However, the medium on which a fermentation starts has a pH of 6 to 8, preferably from 6 to 7, and the pH of the medium generally varies over a narrow range as the microorganism grows. Cultivation is performed aerobically at 25.degree. to 40.degree. C. for a period of 12 to 168 hours. The incubation period is set suitably according to which compound is to be produced. For the incubation period suitable to a specific compound, see below. The AI-77 compound-producing microorganism can be incubated on a slant agar, in a shake flask, or within a medium- to large-size fermentation tank. Fermentation under aeration-agitation is preferred for large-scale production. For incubation with aeration-agitation under aerobic conditions, a defoaming agent such as silicone or polypropylene glycol derivative may be added to the medium with advantage, and this is effective for achieving a greater accumulation of compounds A to G. The total accumulation of compounds A to G can be monitored by the increase in the UV absorption of the culture filtrate at 314 m.mu.. The production of each of the compounds A to G can be monitored by performing TLC or HPLC (high pressure liquid chromatography) on the culture filtrate or the organic extract thereof.
The compounds A to G produced under aerobic fermentation conditions can be substantially isolated from the fermentation broth by combining proper means such as ion exchange resin, macro-reticulate resin, gel filtration agent, chromatography on adsorbent and solvent extraction, using the respective physicochemical properties of the compounds. Compound A is isolated as follows: the filtrate of the culture obtained by a 12- to 48-hr incubation under aerobic conditions is adsorbed on a weak acidic cation exchange resin, e.g., IRC-50 (H type) produced by Rohm and Haas, eluted with a dilute acid, and the eluate is adsorbed on a macro-reticulate resin, e.g., Amberlite XAD-2 or XAD-4 of Rohm and Haas or Dia-ion HP resins of Mitsubishi Chemical Industries Limited, and eluted with water or an organic solvent or a mixture thereof. Suitable organic solvents are those having affinity for water such as alcohols of C.sub.1 to C.sub.4, acetone, dioxane and tetrahydrofuran. Compound A can be desorbed from the macro-reticulate resin with water containing more than 10% of methanol. Hence, by concentrating the eluate in vacuum and freeze-drying the concentrate, compound A can be obtained as a white powder of a salt of the acid used in the eluation of the ion exchange resin. Repeated purification with the macro-reticulate resin gives compound A of higher purity. Compounds B to G are isolated as follows: the filtrate of the culture obtained by a 24- to 168-hr incubation under aerobic conditions is adsorbed on a macro-reticulate resin and subjected to gradient elution with a mixture of water and increasing concentrations of organic solvent. The macro-reticulate resin and organic solvent used may be the same as those used in the recovery of compound A. Compound G is most easily desorbed from the macro-reticulate resin, then comes B followed by C, D, E and F in that order. Therefore, the respective compounds can be isolated and purified by properly selecting the polarity of the macro-reticulate resin and the eluting solvent. To be more specific, Compound G is desorbed with water containing 0 to 10% of an organic solvent; B is desorbed with water contining 20 to 40% of an organic solvent; and C to F are sequentially eluted with higher concentrations of the solvent. The eluates containing G and B are again chromatographed to obtain the respective compounds separately. Another effective method for isolating compounds C to F is to first elute them all together from a macro-reticulate resin with at least 80% of an organic solvent, concentrate the eluate into a powder which is then chromatographed on a column of adsorbent such as silica gel or magnesium silicate. Illustrative eluting solvents are ethyl ether, acetate ester, chloroform and alcohols; they are mixed in suitable proportions and by gradually increasing the polarity of the solvent system, independent elution fractions of F, E, D and C are obtained. Concentating the respective fractions gives compounds F to C. It is to be understood that these compounds can be isolated separately by preparative TLC or preparative HPLC on the same theory of operation.
Next, methods of synthesizing compounds of (I) other than compounds A, B, C, D, F and G are described. First, methods (1) to (23) for producing compounds of (I) wherein X is O are described. Methods (1) to (21) produce compounds of the formula (IIIa) wherein R.sub.1, R.sub.3 and R.sub.5 are the same as defined above. ##STR20##

The product can be typically identified by comparing the UV absorption, IR absorption, NMR and mass spectrum data of the starting material with that of the product. This identification technique is also employed in the methods of synthesis to be described hereunder. A typical method of acylation uses an acid anhydride [(RCO).sub.2 O] or an acid chloride (RCOCl) or both acid (RCOOH) and a dehydration-condensation agent (e.g. dicyclohexyl carboimide).

If an acid chloride is used as an acylating agent, the reaction is performed at a temperature in the range of from room temperature to 40.degree.

C. By so doing, a carbobenzoxy group is introduced in the alcoholic OH group with high selectivity. The product is then acylated in a conventional manner, for example, it is reacted with an excess (1- to 30-times mols) of an acid anhydride [(RCO).sub.2 O] at 40.degree. to 100.degree. C. in pyridine or tertiary amine and a non-protonic solvent.

C. (in vacuum, if necessary) for a period of 10 minutes to 5 hours. By so doing, compounds of (Vb-1) other than AI-77-A are produced. ##STR23##
(26) Compounds of (Va-1) to (Va-27) can be synthesized from AI-77-Ba wherein X is O as well as from (IIIa-10) through (IIIa-35) by the following reaction: a corresponding starting material is dissolved or dispersed in dichloromethane, 3- to 6-fold mols of triethyloxonium tetrafluoroborate in dichloromethane is added to the solution or dispersion, and the mixture is heated at room temperature for a period of 1 to 24 hours. After distilling dichloromethane off, the residual iminoether is reacted with 1.5- to 100-times mols of ammonia or primary amine (NH.sub.2 R) by stirring the mixture at room temperature for 2 to 5 days in the presence of a solvent in a minimum required amount to dissolve both amines and iminoether. Instead of using the solvent, primary amine may be directly added to the reaction system. As a result, the corresponding compounds (Va-1) to (Va-27) are formed. A preferred solvent is a non-protonic polar solvent, and acohols may be used depending on the case.
In a like manner, compounds of (Vb-1) through (Vb-27) can be synthesized from AI-77-B and compounds of (IIIb-10) through (IIIb-35), and compounds of (Vc-1) through (Vc-27) from AI-77-Bc (AI-77-G) and from compounds of (IIIc-10) through (IIIc-35). In an identical manner, compounds of (VIa-1) through (VIa-9) can be synthesized from AI-77-F and from compounds of (IVa-1) through (IVa-8), compounds of (VIb-1) through (VIb-9) from AI-77-Fb and from compounds of (IVb-1) through (IVb-8), and compounds of (VIc-1) through (VIc-9) from AI-77-Fc and from compounds of (IVc-1) through (IVc-8). These compounds are shown in Table 11 below.

In Table 11, the Roman numerals III, IV; V and VI are each a generic symbol for the three states of the respective formulae, i.e. (IIIa), (IIIb) and (IIIc); (IVa), (IVb) and (IVc); (Va) (Vb) and (Vc); and (VIa), (VIb) and (VIc). The symbol R.sub.6 is equivalent to R.sub.6 in appending Claim 1 and represents H or R.
(27) The final reaction products of the methods (1) through (26) may be purified by the following procedures; the final liquid reaction product is concentrated, dissolved in dried methanol or dried ethanol through which hydrogen chloride gas has been passed, and the solution is concentrated to dryness. Repeating this procedure several times gives a lactone compound of the formula (IIIa), which is then adsorbed on a column of a macro-reticulate resin, such as Amberlite XAD-2 (trademark of Rohm & Hass Co), and chromatographed using an eluting solvent comprising water or a hydrophilic organic solvent which is preferably methanol, ethanol, propanol, isopropanol or tetrahydrofuran, or a mixture thereof with water.
The compounds synthesized by the methods (25) and (26) and the compounds converted to each other by the method (24) can be purified from the liquid reaction product by adsorbing them on a column of a macro-reticulate resin, say, XAD-2, and performing chromatography using an eluting solvent comprising an alcohol of C.sub.1 to C.sub.4 or tetrahydrofuran or a mixture of such organic solvent with water.
The synthesis of the compounds of the formula (II) is described hereunder. The method of synthesizing a compound of the formula (VII) below (wherein R.sub.1, R.sub.3, R.sub.5 and R.sub.7 are the same as defined above) is described first [method (28)]. Then, the method of synthesizing a compound of the formula (VIII) below (wherein R.sub.1, R.sub.3 and R.sub.7 are the same as defined above) is described [method (29)]. ##STR24##
(28) A compound of the formula (IIIa) is reacted with amonia or dried primary amine (NH.sub.2 R.sub.3). To react 1.5- to 100-fold mols of free amine or 2.5-to 100-fold mols of an amine salt, a liquid amine is used as a solvent or a gaseous or solid amine is dissolved in a non-protonic solvent (or an alcohol if the case requires) that dissolves both the compound and amine. By heating the reaction mixture at 0.degree. to 30.degree. C. under stirring for a period of 1 to 72 hours, a compound of the formula (VII) wherein the amine has reactes with a 5-membered lactone is produced.
(29) A compound of the formula (VIII) is prepared from a compound of (IVa) under the same reaction conditions as in the method (28) using a non-protonic polar solvent such as dimethylformamide or dimethylsulfoxide.
Alternatively, a compound of the formula (VIII) can be synthesized from a compound of the formula (IV) or (V) by hydrolyzing a six-membered lactone in a weak alkaline solution.
The compounds produced by the methods (28) and (29) as well as the materials from which they are derived are set forth in Table 12 below.

Typical examples of the compounds synthesized by the methods (1) through (29) are given in Table 13. As mentioned before, these compounds exhibit an appreciable pharmaceutical effect. Tables 13, 14 and 15 show the effect of these compounds to inhibit the occurrence of ulcer and edema. The anti-ulcer and anti-edema activity of the compounds was evaluated in efficacy tests described below. The first two symbols that appear in each of the compound names in Tables 13 and 15 represent the compounds synthesized in the methods (1) through (29); for example, IIIa-1 of a compound IIIa-1-1 represent the compound (IIIa-1).
Test 1. Anti-ulcer test
Male Wistar rats weighing about 150 g on average were not fed for 24 hours before the test. Then a solution or suspension of a predetermined concentration of the test compound in physiological saline was administered to them intraperitoneally. One hour after the administration, each rat was restrained in a net cage and submerged in a water both (21.degree. C.) from the tail to xiphistrenun for 6 hours. Test animals were then killed (by dislocation of the cervical vertebrae), the stomach was removed and incised along the curvatura ventriculi major, and the inside wall of the stomach was pathologically examined under microscopic observation. Rats in which the occurrence of an ulceration was substantially not observed were rated O, while others were rated 0.5, 1, 2 or 3, depending on the severity of the ulcer development. The percent inhibition of ulcer was calculated by the following formula: ##EQU1##
Table 13 shows the percent ulcer inhibition for each compound when it was administered intraperitoneally in a dose of 50 mg/kg.
Test 2. Anti-edema test
Male Wistar rats weighing about 150 g on average were starved overnight prior to the test. They were than orally administered 100 mg/kg of the test compound. One hour later, the pad of a hindfoot of the animal was injected with 1 mg of carrageenan. The volume of the foot was measured both before the injection of carrageenan and three hours after the injection. The percent edema inhibition of the test compound was calculated from the ratio of the increase in the volume of the affected foot of the test animals to the increase in the volume of the affected foot of the controls. The results are shown in Table 15.
Compounds AI-77-A and AI-77-B of the formula (I) as well as their derivatives are preferred in view of their high anti-ulcer activity. Particularly preferred compounds are AI-77-A, (Vb-1), (Vb-5), (Vb-10), (Vb-14), (Vb-19) and (Vb-23), as well as AI-77-B, (IIIa-13), (IIIa-18), (IIIa-22), (IIIa-27) and (IIIa-31), and compounds of the formulae (VII-1), (VII-10) and (VII-19).
Compounds of (IIIa-18), (IIIa-22) and (IIIa-27) exhibit particularly strong anti-edema effect.

After the fermentation, the broth was filtered through a hollow fiber ultrafilter cell. The resulting filtrate was passed through a column packed with 5 liters of Amberlite XAD-2. The column was washed with 15 liters of water, and compound G was eluted with 20 liters of water. The fraction was concentrated and dried to give 4.8 g of a crude powder of compound G. (The powder can be purified further by means of the technique described in Example 6.) The column was fed with 50 liters of 10% aqueous methanol solution to remove the unwanted portion, and compound B was eluted with 150 liters of 30% aqueous methanol solution. Upon concentration of the eluate in vacuum, 42 g of a crude specimen of compound B resulted. The specimen was dissolved in 2 liters of boiling water and allowed to cool to give 23 g of a white crystal of a tetrahydrate salt of compound B. The crystal was dried on phosphorus pentoxide in vacuum at 60.degree. C. for 6 hours. The dried crystal had physicochemical properties that corresponded to the physicochemical data of compound B described herein. After elution of compound B, 15 liters of 80% aqueous methanol was passed through the column of XAD-2 to elute compounds C to F altogether. Upon concentration in vacuum, 5.6 g of a powder containing compounds C to F resulted. As will be described in Example 7, compounds C to F in the powder can be separated from each other.
EXAMPLE 5
Production of Compounds B to F
A 20-liter jar fermentor was charged with 10 liters of a medium identical with what was used in Example 1, and inoculated with 500 ml of the seed prepared in Example 1. Fermentation was conducted at 30.degree. C. for a day (0.5 v/v/m, 300 rpm). A 200-liter fermentation tank charged with 125 liters of a medium identical with what was used in Example 1 was inoculated with 7 liters of the culture as a seed. Fermentation was conducted at 30.degree. C. for 18 hours (0.5 v/v/m, 300 rpm). A 5-m.sup.3 fermentation tank charged with 2.5 m.sup.3 of a medium identical with what was used in Example 3 was inoculated with a seed comprising all of the culture obtained. Fermentation was conducted at 30.degree. C. for 4 days (0.5 v/v/m, 170 rpm).
After the fermentation, the broth was filtered through a hollow fiber ultrafilter cell. The filtrate was passed through a first column packed with 130 liters of XAD-2. After washing the column with 2.6 m.sup.3 of 10% aqueous methanol, 2.6 m.sup.3 of 30% aqueous methanol was passed through the column to elute compound B. The eluate mixed with an equal amount of water was continuously passed through a second column packed with 80 liters of XAD-2 to adsorb compound B on the column again. After washing the column with 1.6 m.sup.3 of 20% aqueous methanol, compound B was eluted with 180 liters of 100% methanol.
Concentrating the methanol eluate gave 650 g of a tetrahydrate salt of compound B. Upon high pressure liquid chromatography, the specimen was found to have a purity of 98%. It could be purified further by recrystallization from boiling water.
After eluting compound B with 30% aqueous methanol, the first column was fed with 260 liters of 80% aqueous methanol to give an eluate containing compounds C to F. If necessary, Compounds C to F can be separated from each other by subjecting a concentrate of the eluate to the method described in Example 7.
EXAMPLE 6
Purification of Compound G

Separation of Compounds C to F
Three grams of the powder containing compounds C to F obtained in Example 4 was dissolved in methanol, adsorbed on 5 g of silica gel (Silica 60 Extra Pure of 70-200 Tyler mesh manufactured by Merck & Co., Inc.) and methanol was distilled off. A suspension of 600 g of silica gel (the same as used above) in ethyl ether was filled in a column. The silica gel onto which the powder containing C to F was adsorbed was suspended in ethyl ether to form a slurry, which was placed on top of the column. Elution was performed by passing three developing solvents, (1) ethyl ether, (2) a mixture of ethyl ether and ethyl acetate (7:3 by volume) and (3) ethyl acetate, through the column sequentially. The eluting operation was conducted by monitoring the eluates from TLC on silica gel: the elution with solvent (1) was continued until the UV absorbing substance that moved to the tip of a silica gel (5714 of Merck & Co., Inc.) on TLC using that solvent as a developing system was no longer eluted; the elution with solvent (2) was continued until the UV absorbing substance positioned at Rf=0.48 (F) on TLC using that solvent as a developing system was no longer eluted; the elution with solvent (3) was continued until the UV absorbing substances positioned at Rf=0.55 (E), Rf=0.47 (D) and Rf= 0.28 (C) on TLC using that solvent as a developing system were no longer eluted. The eluted fractions of the respective compounds on TLC were combined and concentrated in vacuum. As a result, 112 mg of a crystalline powder of E, 36 mg of a white powder of D and 105 mg of a white powder of C were obtained. The compounds C to F obtained had physicochemical properties that corresponded to the physicochemical data for the respective compounds described herein.
