The fungus Candida albicans of the examples of the present invention was purchased commercially.
EXAMPLE 1 structural characterization of Compounds
The fungus Candida albicans was inoculated under aseptic conditions into potato medium (200g of potato aqueous extract prepared at 1L volume, 20g of glucose), 500 mL/bottle, for a total of 600 bottles. After the fungus culture medium is subjected to constant-temperature shaking culture for 5 days (140r/min) at 32 ℃, the fungus culture medium is extracted by using ethyl acetate (3 times), and ethyl acetate extract is concentrated by a rotary evaporator to obtain the metabolite extract of the fungus Candida albicans. Separating the extract by silica gel column chromatography with petroleum ether-ethyl acetate system as eluent to obtain silica gel column chromatography fraction. The fractions were further purified for chemical composition using preparative liquid chromatography in combination with high performance liquid chromatography. Using 55% methanol- (0.3%, v/v) trifluoroacetic acid aqueous solution as a mobile phase, preparing a liquid phase with the flow rate of 8mL/min and the detection wavelength of 210nm, respectively collecting liquid phase chromatographic peaks, and evaporating the solvent under reduced pressure to obtain solid substances, namely the compounds 1-7 respectively.
EXAMPLE 2 spectroscopic data for Compounds 1-7
EXAMPLE 3 evaluation of anti-inflammatory action of Compounds 1-7
Mouse macrophage RAW264.7 was seeded at 4 × 105 in 96-well plates and cultured overnight. The culture medium comprises DMEM culture solution containing 10% fetal calf serum, 50U/mL penicillin and streptomycin. Thereafter, LPS was added at a concentration of 5. mu.g/mL for 2 hours, and then compounds 1 to 7 (0.1. mu.M) were added, respectively, and after 12 hours, the levels of inflammatory factors IL-1. beta. and IL-6 were measured by ELISA kits, respectively.
TABLE 1 protective Effect of Compounds 1-7 on LPS-induced cellular inflammation
According to the content of the inflammatory factors IL-1 beta and IL-6 in the table 1, the compounds 1-7 can effectively relieve the cell inflammation induced by LPS, and have significant difference compared with a control group.
Example 4 evaluation of therapeutic Effect of inflammatory bowel disease
C57BL/6J male mice were bred for 6-8 weeks, after 1 week of acclimatization, and randomized into four groups (inflammatory bowel disease model control group, compound 4-treated group, compound 5-treated group, obeticholic acid control group) of 6 mice each. In the first week, the compounds 4 and 5 and obeticholic acid were prepared into hydroxymethylcyclodextrin solutions, and the solutions were gavaged to mice at a dose of 5 mg/kg. One week after dosing, dextran sodium sulfate was formulated into a 2.5% aqueous solution and placed in the four groups of mouse drinking bottles described above to initiate inflammatory bowel disease molding. The body weight of the mice was recorded daily and observed for activity, diarrhea, bloody stool, and rectal bleeding. Compared with the mice of inflammatory bowel disease molding group, the compounds 4 and 5 can improve the health state of the mice, relieve the weight reduction trend, improve diarrhea and reduce colorectal hemorrhage (figure 22). When the model is made for 8 days, the diarrhea and the hematochezia of the mice are serious, and the weight is obviously reduced. After 4 groups of mice were sacrificed, the colons were intercepted and photographed on a piece of coordinate paper to count the length of the colons. As shown in fig. 23, compounds 4 and 5 were able to protect the colon of mice, which is substantially the same length as the positive control drug obeticholic acid-treated group.
Taking fresh colon tissue, storing at-80 ℃, taking part of tissue sample, extracting RNA by a tissue grinder, performing reverse transcription, and measuring the expression conditions of inflammatory factors such as IL-1 beta, IL-6, TNF-alpha, INF-gamma and the like by using an RT-PCR technology to evaluate the inflammatory reaction condition of the intestinal tract of the mouse. As shown in figure 24, compounds 4 and 5, when administered to mice, had a significant relief of colonic inflammation, similar to that of the positive drug obeticholic acid treated mice.
The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solutions of the present invention can be made by those skilled in the art without departing from the spirit of the present invention, and the technical solutions of the present invention are within the scope of the present invention defined by the claims.
