Description
Technical field
The invention belongs to biomedicine fields, are related to three lienomycin class compound (Trienomycin A) preparation methods, three
Lienomycin class compound and the high-yield culture medium of application and preparation method thereof.
Background technique
Natural products refers to the internal constituent of animal in nature, plant and microorganism, or produces from its metabolism
Chemical component isolated in object, with biological activity or pharmacological activity, natural products be used to treat as drug
With existing thousands of years of the history of prevention disease.Microorganism is one of diversity species the most abundant in nature, is that we are existing
And the following huge treasure-house for needing to go to further investigate and excavate.The biology in 20,000 multiple-microorganism sources having found
In active material, about 45% is generated by actinomyces, and 17% is generated by slime bacteria, and 38% is generated by fungi[1].So actinomyces
It is very important medicament sources, especially streptomycete.Although the extensive use of antibiotic, infectious disease is still that population in the world is dead
One of the main reason for dying.In the case where no new treatment, to the year two thousand fifty, the death rate as caused by the infection that can not be treated
It is expected that 10 times or more will be increased.The natural products for being isolated from bacterium has become the main source of clinically useful antibiotic[2]。
Ansamycin is a kind of macrolactams antibiotic from plant or microorganism, has extensive biology living
Property, such as antiviral and antitumor and antibacterium[3].Although ansamycins antibiotic type is few, physiological activity extensively,
Druggability is high, is a kind of antibiotic of significant.TrienomycinA is a kind of typical benzene ansamycin, by Umezawa
It is isolated in streptomycete for the first time[4], relative to other ansamycins compounds, it shows more significant anti-
Tumor promotion[5].Trienomycin A belongs to ansamycin family C-17 class compound, has to HeLa-S3 cervical cancer cell poison
Remarkable activity.The compound has relevant chemical synthesis research report at present, but because synthesis process is cumbersome and not environmentally protective
Make its structure of modification, in terms of progress it is slow.

Extract liquor extracts five times, is extracted after concentration with petroleum ether and methanol 1:1, to be separated after methanol is mutually concentrated.
The extraction of 1.2TrienomycinA separates:
Methanol Xiang Jingzhu chromatographic grade elution to be separated obtained in 1.1 is successively obtained into 10 fractions and (is specifically shown in figure
It 3) is, fraction A, fraction B ... fraction J by fraction outflow serial number, chromatographic column RP-18, condition of gradient elution is methanol-water
(10%-100%);Isolated 3 fractions after fraction F is eluted using gel column LH-20 (solvent is methanol), by distillate flow
Serial number is fraction F1, fraction F2, fraction F3 out, and fraction F2 is through isolated 22 fractions of high-speed countercurrent chromatography, by evaporating
It is TrienomycinA, fraction that serial number, which is distributed, as fraction F2.1, fraction F2.2 ... fraction F2.22, fraction F2.12
The acquisition amount of F2.12 is 52.5mg;The dicyandiamide solution of high-speed countercurrent chromatography is n-hexane: ethyl acetate: methanol: water 4:6:
4:6 (volume ratio).
The assay of Trienomycin A in 1.3 tunnings:
Trienomycin A standard items (standard items HPLC figure is shown in Fig. 1) 1.3mg is accurately weighed, is configured to methanol dissolution
The mother liquor of 1mg/mL, mother liquor is for diluting configuration standard gradient liquid (mg/mL): 0.0125,0.025,0.05,0.075,0.1,
0.2.In the identical situation of sampling volume (10 μ L), its absorption value is measured at 271nm, with concentration (mg/mL) for abscissa,
With the detection peak area (S) of each gradient mark product Trienomycin A for ordinate, standard curve is drawn, standard curve side is obtained
Journey y=31159x-98.837 (R2=0.9964) (see Fig. 2).By concentrate obtained in 1.1 it is dry after, accurately weigh its matter
Amount calculates Trienomycin A content according to the standard curve of drafting.By taking 7L tunning as an example, 5.3mg fermentation is accurately weighed
Product crude product, when sampling volume is 10 μ L, it is 2182 that Trienomycin A peak area is measured at 271nm absorption, according to mark
It is 8.5mg/L that directrix curve equation, which can obtain theoretical yield, actually obtains 7.2mg/L.
The comparison of 1.4 basal medium TSB progress Trienomycin A fermented and cultured
Cocoa streptomycete A Su sp. strain activation method: picking H2S5 mycelium lines TSB solid from glycerol tube
On plate, cultivated 3 days in 28 DEG C;H2S5 single bacterium on picking TSB plate is fallen in TSB fluid nutrient medium, and 28 DEG C, 130rpm training
It supports 3 days.TSB Liquid Culture based formulas: tryptone: 1.5%;Soy peptone: 0.5%;Sodium chloride: 0.5%;Water: 1L,
pH 7.2。
Cocoa streptomycete A Su sp. strain fermentation culture conditions: the culture solution of activated H2S5 is pressed to 5% inoculation
Amount is inoculated in the 250mL culture bottle of the fluid nutrient medium containing 100mLTSB, and 28 DEG C, 130rpm is cultivated 5 days.Do three in parallel,
It is 1L.After fermentation, isometric ethyl acetate is added, ultrasonic extraction is three times, 30 minutes every time, dense by ethyl acetate phase
It contracts to be determined.By taking wherein 1L as an example, 10mg tunning is accurately weighed, when sampling volume is 10 μ L, is surveyed at 271nm absorption
Obtaining Trienomycin A peak area is 2892, and can obtain theoretical yield according to calibration curve equation is 0.96mg/L, due to yield pole
It is low, later separation is not carried out.
After measured, the yield of basal medium TSB is only 0.96mg/L, (uses solid fermentation of the invention after optimization
Culture medium) output increased nearly 8 times.
