- the concentrate obtained is chromatographed on a reverse phase with methanol ammonium acetate buffer and by detection in the UV at 226 nm
- the invention relates to an antifungal agent containing a compound according to the invention.
- the invention relates to a cytostatic agent containing a compound according to the invention.
- an embodiment of the invention relates to Archangium gephyra DSM 11 092.
- the bacterium Archangium gephyra belongs to the order of the Myxococcales (Myxobacteria), subordinate to Cystobacterineae, family Archangiaceae.
- Myxobacteria Myxobacteria
- Cystobacterineae family Archangiaceae.
- the Archangium gephyra Ar 315 production line was founded in February 1973 by Dr. Reichenbach from a sample of a compost heap in the botanical garden in Freiburg, German country isolated. It was deposited with the German Collection of Microorganisms (DSM) in 1996 under the number DSM 11 092.
- the stock is kept on agar plates, preferably on yeast agar (VY / 2 agar).
- This medium contains 0.5% baker's yeast, 0.1% CaCl2 x 2H2O, 0.1 ⁇ g / 1 cyanocobalamin and 1.2% agar.
- the pH is adjusted to 7.4.
- the medium is sterilized by autoclaving.
- the plate cultures are incubated at 30 ° C.
- the vegetative cells are long, slim rods, about 6 to 9 ⁇ m long and 0.8 ⁇ m thick. Due to the sliding movement of the bacteria, the colonies spread quickly over the culture plate.
- the swarm colony on Hefeagar is thin, film-like, reddish brown.
- the yeast cells in the medium are broken down, as can be seen from the clarification plant that is being built around the colonies.
- the stem often forms pale brown fruiting bodies on this medium, which are made up of meandering ridges and contain strongly refractive myxospores. The latter are short, thick, somewhat irregular sticks, about 2.5 to 4 mm long and 1.2 to 1.8 mm thick.
- the Ar 315 strain produces substances, namely tubulysins, that inhibit the growth of fungi, human cancer cells and other animal cell cultures.
- the inhibitors can be isolated both from the cells and from the culture supernatant.
- a typical Fermen- The process proceeds as follows: A fermentor with a working volume of 350 1 is filled with 300 1 culture medium (composition: 0.5% probion (single-cell protein from Hoechst); 1.0% starch (Cerestar Krefeld); 0.2% glucose; 0 , 1% yeast extract; 0.1% MgS0 4 x 7H 2 0; 0.1% CaCl 2 x 2H 0; 0.1 ⁇ g / 1 cyanocobalamin; alternatives to probion are soy flour or corn glue). The pH is adjusted to 7.4 with KOH.
- composition 0.5% probion (single-cell protein from Hoechst); 1.0% starch (Cerestar Krefeld); 0.2% glucose; 0 , 1% yeast extract; 0.1% MgS0 4 x 7H 2 0; 0.1% CaCl 2 x 2H 0; 0.1 ⁇ g / 1 cyanocobalamin; alternatives to probion are soy flour or corn glue).
- the pH is adjusted to 7.4
- 1% (v / v) of an adsorber resin (Amberlite XAD-16, Rohm & Haas) is added to the medium. Inoculation is carried out with 10 l of a 3-day-old preculture which was produced in the same medium in a correspondingly smaller fermenter. Is fermented at 30 ° C with a stirring speed of 150 U / min and an aeration rate of 10 vol .-% per min. Initial foam formation is prevented by adding 50 ml silicone anti-foam (e.g. Tegosipon, Goldschmidt AG, Essen). The pH increases during the fermentation. The increase is achieved by adding 5 percent. Sulfuric acid limited to 7.8. The fermentation is ended after 5 days.
- an adsorber resin Amberlite XAD-16, Rohm & Haas
- the adsorber resin is separated from the culture in a process filter (0.7 m, 100 mesh) and eluted with 15 l of methanol in the course of 3 h.
- the eluate is concentrated under vacuum until the water phase occurs, which is then extracted three times with ethyl acetate. After concentrating the organic phase in vacuo at a bath temperature of 30 ° C., 36 g of crude extract are obtained.
- tubulysin A After evaporating the combined fractions containing tubulysin A, tubulysin B and tubulysin C to the water phase, the mixture is extracted with ethyl acetate and, after evaporation in vacuo and drying, 420 mg of tubulysin A, 240 mg of tubulysin B and 20 mg of tubulysin C.
- UV (methanol) lambda max (log epsilon) 225 (4.20); 250 (3.86); 280 (3.30)
- UV (methanol) lambda max (log epsilon) 225 (4.23); 250 (3.91); 280 (3.26)
- IR KBr 3421; 2964; 2935; 2878; 1742; 1667; 1550; 1517; 1235 cm "1
- tubulysins have a cytostatic effect on fungi, human cancer cell lines and other animal cell cultures (see table). They lead to a rapid breakdown of the microtubule scaffold in the cells. The actin skeleton remains intact. Under the influence of the tubulysins, adherently growing L929 mouse cells increase their cell volume without dividing and develop large cell nuclei, which then disintegrate in an apoptotic process.
