The process for preparing the starting compound [II] (SEQ ID NO: 1) or a salt thereof of the present invention is explained in detail in the following.
PROCESS A
The compound [II] (SEQ ID NO: 1) or a salt thereof can be prepared by the fermentation process.
The fermentation process is explained in detail in the following.
The compound [II] (SEQ ID NO: 1) or a salt thereof of this invention can be produced by fermentation of the compound [II] (SEQ ID NO: 1) or a salt thereof-producing strain belonging to the genus Coleophoma such as Coleophoma sp. F-11899 in a nutrient medium.
(i) Microorganism:
Particulars of the microorganism used for producing the compound [II] (SEQ ID NO: 1) or a salt thereof is explained in the following.
The strain F-11899 was originally isolated from a soil sample collected at Iwaki-shi, Fukushima-ken, Japan. This organism grew rather restrictedly on various culture media, and formed dark grey to brownish grey colonies. Anamorph (conidiomata) produced on a steam-sterilized leaf segment affixed on a Miura's LCA plate.sup.1) or a corn meal agar plate by inoculating the isolate, while neither teleomorph nor anamorph formed on the agar media. Its morphological, cultural and physiological characteristics are as follows.
1) Miura, K. and M. Y. Kudo: An agar-medium for aquatic Hyphomycetes., Trans. Ycolo. Soc. Japan, 11:116-118, 1970.
Cultural characteristics on various agar media are summarized in Table 1. Cultures on potato dextrose agar grew rather rapidly, attaining 3.5-4.0 cm in diameter after two weeks at 25.degree. C. This colony surface was plane, felty, somewhat wrinkly and brownish grey. The colony center was pale grey to brownish grey, and covered with aerial hyphae. The reverse color was dark grey. Colonies on malt extract agar grew more restrictedly, attaining 2.5-3.0 cm in diameter under the same conditions. The surface was plane, thin to felty and olive brown. The colony center was yellowish grey, and covered with aerial hyphae. The reverse was brownish grey.
The morphological characteristics were determined on basis of the cultures on a sterilized leaf affixed to a Miura's LCA plate. Conidiomata formed on the leaf segment alone. They were pycnidial, superficial, separate, discoid to ampulliform, flattened at the base, unilocular, thin-walled, black, 90-160(-200 ) .mu.m in diameter and 40-70 .mu.m high. Ostiole was often single, circular, central, papillate, 10-30 .mu.m in diameter and 10-20 .mu.m high. Conidiophores formed from the lower layer of inner pycnidial walls. They were hyaline, simple or sparingly branched, septate and smooth. Conidiogenous cells were enteroblastic, phialidic, determinate, ampulliform to obpyriform, hyaline, smooth, 5-8.times.4-6 .mu.m, with a collarette. The collarettes were campanulate to cylindrical, and 14-18.times.3-5 .mu.m. Conidia were hyaline, cylindrical, thin-walled, aseptate, smooth and 14-16(-18).times.3-3 .mu.m.
The vegetative hyphae were septate, brown, smooth and branched. The hyphal cells were cylindrical and 2-7 .mu.m thick. The chlamydospores were absent.
The strain F-11899 had a temperature range for growth of 0.degree. to 31.degree. C. and an optimum temperature of 23.degree. to 27.degree. C. on potato dextrose agar.
The above characteristics indicate that the strain F-11899 belongs to the order Coelomycetes.sup.2), 3), 4). Thus, we named the strain "Coelomycetes strain F-11899".

These characteristics were observed after 14 days of incubation at 25.degree. C. The color descriptions were based on the Methuen Handbook of Colour.sup.5).
5) Kornerup, A. and Wanscher, J. H.: Methuen Handbook of Colour (3rd ed.), 252 p., Methuen, London, 1983.
A culture of Coelomycetes strain F-11899 thus named has been deposited with the Fermentation Research Institute Agency of Industrial Science and Technology (1-3, Higashi 1 chome, Tsukuba-shi, IBARARKI 305 JAPAN) on Oct. 26, 1989 under the number of FERM BP-2635.
After that, however, we have further studied the classification of the strain F-11899, and have found that the strain F-11899 resembled Coleophoma empetri (Rostrup) Petrak 1929 2), 3), 4) belonging to the order Coelomycetes, but differed in some pycnidial characteristics: globose or flattened at the base, immersed, and not papillate.
Considering these characteristics, we classified this strain in more detail and renamed it as "Coleophoma sp. F-11899".
In this connection, we have already taken step to amend the name, "Coelomycetes strain F-11899" to Coleophoma sp. F-11899 with the Fermentation Research Institute Agency of Industrial Science and Technology on Sep. 21, 1990.
(ii) Production of the compound [II] (SEQ ID NO: 1) or a salt thereof
The compound [II] (SEQ ID NO: 1) or a salt thereof of this invention is produced when the compound [II] (SEQ ID NO: 1) or a salt thereof-producing strain belonging to the genus Coleophoma is grown in a nutrient medium containing sources of assimilable carbon and nitrogen under aerobic conditions (e.g. shaking culture, submerged culture, etc.).
The preferred sources of carbon in the nutrient medium are carbohydrates such as glucose, sucrose, starch, fructose or glycerin, or the like.
The preferred sources of nitrogen are yeast extract, peptone, gluten meal, cotton seed flour, soybean meal, corn steep liquor, dried yeast, wheat germ, etc., as well as inorganic and organic nitrogen compounds such as ammonium salts (e.g. ammonium nitrate, ammonium sulfate, ammonium phosphate, etc.), urea or amino acid, or the like.
The carbon and nitrogen sources, though advantageously employed in combination need not to he used in their pure form because less pure materials, which contain traces of growth factors and considerable quantities of mineral nutrients, are also suitable for use.
When desired, there may be added to the medium mineral salts such as sodium or calcium carbonate, sodium or potassium phosphate, sodium or potassium chloride, sodium or potassium iodide, magnesium salts, copper salts, zinc salt, or cobalt salts, or the like.
If necessary, especially when the culture medium foams seriously a defoaming agent, such as liquid paraffin, fatty oil, plant oil, mineral oil or silicone, or the like may be added.
As in the case of the preferred methods used for the production of other biologically active substances in massive amounts, submerged aerobic cultural conditions are preferred for the production of the compound [II] (SEQ ID NO: 1) or a salt thereof in massive amounts.
For the production in small amounts, a shaking or surface culture in a flask or bottle is employed.
Further, when the growth is carried out in large tanks, it is preferable to use the vegetative form of the organism for inoculation in the production tanks in order to avoid growth lag in the process of production of the compound [II] (SEQ ID NO: 1) or a salt thereof. Accordingly, it is desirable first to produce a vegetative inoculum of the organism by inoculating a relatively small quantity of culture medium with spores or mycelia of the organism and culturing said inoculated medium, and then to transfer the cultured vegetative inoculum to large tanks. The medium, in which the vegetative inoculum is produced, is substantially the same as or different from the medium utilized for the production of the compound [II] (SEQ ID NO: 1) or a salt thereof.
Agitation and aeration of the culture mixture may be accomplished in a variety of ways. Agitation may be provided by a propeller or similar mechanical agitation equipment, by revolving or shaking the fermentor, by various pumping equipment or by the passage of sterile air through the medium. Aeration may be effected by passing sterile air through the fermentation mixture.
The fermentation is usually conducted at a temperature between about 10.degree. C. and 40.degree. C., preferably 20.degree. C. to 30.degree. C., for a period of about 50 hours to 150 hours, which may be varied according to fermentation conditions and scales.
When the fermentation is completed, the culture broth is then subjected for recovery of the compound [II] (SEQ ID NO: 1) or a salt thereof to various procedures conventionally used for recovery and purification of biological active substances, for instance, solvent extraction with an appropriate solvent or a mixture of some solvents, chromatography or recrystallization from an appropriate solvent or a mixture of some solvents, or the like.
According to this invention, in general, the compound [II] (SEQ ID NO: 1) or a salt thereof is found both in the cultured mycelia and cultured broth. Accordingly, then the compound [II](SEQ ID NO: 1) or a salt thereof is removed from the whole broth by means of extraction using an appropriate organic solvent such as acetone or ethyl acetate, or a mixture of these solvents, or the like.
The extract is treated by a conventional manner to provide the compound [II]](SEQ ID NO: 1) or a salt thereof, for example, the extract is concentrated by evaporation or distillation to a smaller amount and the resulting residue containing active material, i.e. the compound [II] (SEQ ID NO: 1) or a salt thereof is purified by conventional purification procedures, for example, chromatography or recrystallization from an appropriate solvent or a mixture of some solvents.
When the object compound is isolated as a salt of the compound [II](SEQ ID NO: 1), it can be converted to the free compound [II] (SEQ ID NO: 1) or another salt of the compound [II] (SEQ ID NO: 1) according to a conventional manner.

In order to show the usefulness of the polypeptide compound [I] (SEQ ID NO: 1) of the present invention, some biological data of the representative compounds are explained in the following.
Test 1 Antimicrobial Activity (1):
Antimicrobial activity of the compound of Example 2 disclosed later (hereinafter referred to as FR131535 substance) was measured by micro-broth dilution method in 96 well multi-trays employing yeast nitrogen base dextrose medium. To a 50 .mu.l sample solution with serial 2-fold dilution was added a 50 .mu.l of microorganism suspension in saline to yield a final concentration of 1.times.10.sup.5 colony forming units/ml. The Candida cultures were incubated at 37.degree. C. for 22 hours. After incubation, the growth of microorganism in each well was determined by measuring the turbidity. The results were shown as IC.sub.50 value in which concentration the turbidity was half of that in the well without sample. The results are shown in Table 2.

(1) Fermentation of Actinoplanes utahensis
The enzyme which is useful for eliminating N-acyl group of FR901379 substance (SEQ ID NO: 1) is produced by certain microorganisms of the Actinoplanaceae, preferably the microorganism Actinoplanes utahensis IFO-13244.
A stock culture of Actinoplanes utahensis IFO-13244 is prepared and maintained on agar slant. A loopful of the slant culture was inoculated into a seed medium consisted of starch 1%, sucrose 1%, glucose 1%, cotton seed flour 1%, peptone 0.5%, soy bean meal 0.5% and CaCO.sub.3 0.1%. The inoculated vegetative medium was incubated in a 225-ml wide mouth Erlenmeyer flask at 30.degree. C. for about 72 hours on a rotary shaker.
This incubated vegetative medium was used directly to inoculate into a production medium consisted of sucrose 2%, peanut powder 1%, K.sub.2 HPO.sub.4 0.12% KH.sub.2 PO.sub.4 0.05% and MgSO.sub.4 7H.sub.2 O 0.025%. The inoculated production medium was allowed to ferment in a 30-liter jar fermentor at a temperature of 30.degree. C. for about 80 hours. The fermentation medium was stirred with conventional agitators at 250 rpm and aerated at 20 liters per minute. The vegetative mycelium was collected from the fermented broth by filtration and once washed with water. The washed mycelium was directly used to eliminate N-acyl group of FR901379 substance (SEQ ID NO: 1) as an enzyme source.
(2) Elimination Condition
FR901379 substance was dissolved in 0.25M phosphate buffer (pH 6.5) at a concentration of 0.9 mg/ml. To a 36-liter of the solution was added a 2 kg wet weight of washed mycelium of Actinoplanes utahensis IFO-13244. The elimination reaction was carried out at 37.degree. C. under for 23 hours. Reduction of FR901379 substance (SEQ ID NO: 1) and increase of the deacylated FR901379 substance (SEQ ID NO: 1) (hereinafter referred to as FR133303 substance) were measured using a HPLC equipped with a reverse phase column. From a 30 g of FR901379 substance (SEQ ID NO: 1), a 22.2 g of FR133303 substance was formed in the reaction mixture.
(3) Isolation of FR133303 Substance (SEQ ID NO: 1)
The reaction mixture described above was filtered with a filter aid. The mycelial cake was discarded. The filtrate thus obtained was passed through a column of activated carbon (2 L). The column was washed with 6 L of water and eluted with 12 L of 50% aqueous acetone. The eluate was evaporated in vacuo to remove acetone and then passed through a column (4 L) of YMC GEL ODS-AM 120-S50 (Yamamura Chemical Labs). The column was washed with water and eluted with 2% aqueous acetonitrile containing 50 mM NaH.sub.2 PO.sub.4. Elution was monitored by analytical HPLC, using a column of LiChrospher 100 RP-18 (Cica-MERCK) and a solvent system of 3% aqueous acetonitrile containing 0.5% NH.sub.4 H.sub.2 PO.sub.4 at a flow rate of 1 ml/min, detecting the FR133303 substance with a UV monitor at 210 nm. The fractions containing the FR133303 substance were combined and passed through a column of activated carbon (400 ml). The column was washed with water and eluted with 50% aqueous acetone. The eluate was concentrated in vacuo to remove acetone and lyophilized to give 16.4 g of FR133303 substance (SEQ ID NO: 1) as a white powder.
