A new immunosuppressive agent as glycyrol has significant immunosuppressive activity, thus is useful as an immunosuppressive agent to treat relative diseases, wherein the glycyrol is a coumestrol compound extracted from glycyrrhiza, which is a small molecular compound with novel chemical structure. Tests prove that the glycyrol can inhibit the increment of T lymphocyte induced by canavaline A and inhibit one-way mixed lymphocyte reaction (MLR), release the inflammatory symptom of delayed hypersensitivity and inhibit the homologous allogenic organ transplantation rejection. The glycyrol is a high-effective low-toxicity immunosuppressive agent, with small molecular weight and simple structure, which is easy to be modified and to prepare different drug agents, therefore, the compound is a new generation immunosuppressive agent.

The present invention provides gero-protective pharmaceutical compositions and methods, the compositions being adapted to enhance at least one of cell survival and cell metabolism in a mammalian subject, the pharmaceutical compositions include at least two of Withaferin a or its structural analogs, coumestrol, ginsenoside, quinidine, silymarin, licochalcone a, lipoic acid and apigenin, in a pharmaceutically effective amount.

The invention relates to the technical field of breeding of small yellow croakers, in particular to a feminization inducing method for small yellow croakers with undifferentiated sex glands. The method comprises the following steps: placing fry of small yellow croakers hatched for 13-15 days and having undifferentiated sex glands in seawater containing estrogen with a low concentration of 1-10 [mu]g/L for dipping bath, and performing dipping bath for 2 hours every day and continuous for 60 days, so as to enable the crowd of small yellow croakers to be completely feminized, wherein the selectable estrogen comprises estrone, soybean isoflavone, estradiol, estriol, coumestrol and genistein. The effect of estradiol is more obvious, 1 [mu]g/L estradiol can ferminize 96.6% of a crowd of small yellow croakers, 10 [mu]g/L estradiol can ferminize 100% of a crowd of small yellow croakers, the induction rate is high, the operatability is high, natural environment does not cause limit. Female parent fish guarantee is provided for large-scale artificial breeding of small yellow croakers, a technological route is opened up for study on sex control and monosex breeding of small yellow croakers, and a route for solving the problem of less of female population of small yellow croakers is provided.

The invention discloses a composition for activating mitochondria. The composition is prepared from the following raw materials in parts by weight: 10-20 parts of coumestrol, 5-10 parts of coenzyme Q10, 10-20 parts of ellagic acid, 1-3 parts of quercetin, 5-10 parts of a grape seed extract, 10-15 parts of a silybum marianum extract, 10-15 parts of an olive leaf extract, 10-15 parts of borage, 3-6 parts of nostoc sphaeroids kutz ferment powder, 4-8 parts of broken-down wall ganoderma lucidum spore powder, 10-15 parts of acetylcarnitine and 5-10 parts of superfine grinding powder of pecan bark. According to the obtained composition, the activity of mitochondria enzyme can be improved and the quantity of mitochondria DNAs can be increased, so that the composition is capable of activating the mitochondria and increasing biosynthesis of the mitochondria. Therefore, the composition can be effectively used for preventing or treating various mitochondria activity reduction-related diseases, such as degenerative diseases and parkinson's disease.

The present invention relates to a skin cosmetic product containing 3,9-diferulylcoumestrol, especially to a skin cosmetic product containing a compound in which ferulylic acid is bonded to a coumestrol. The skin cosmetic product has several excellent effects for improving cosmetic disorders, such as anti-aging effect, whitening effect and hair-seeding effect.

The invention discloses a synthetic method of a polyhydroxy substituted coumestrol natural product. 2-bromine-4-hydroxyphenylacetic acid serves as a raw material to make a condensation reaction with a hydroxy substituted salicylaldehyde compound, and a hydroxy substituted 3-(2-bromine-4-hydroxycyclohexyl phenyl)-7-hydroxy coumarin compound is obtained; and then a hydroxylation/oxidative coupling reaction is made under the condition of a catalyst and microwave heating, and the polyhydroxy substituted coumestrol natural product is obtained. The synthetic method is simple in route, easy and convenient to operate, high in yield, soft in reaction condition, free of needs of precious metal catalyzing, high in atom economy and low in cost, and multiple steps of cascade reactions are made simultaneously.
