| In vitro study | Ascomectin, isolated from Streptomyces, inhibits the in vitro immune response of mouse mixed lymphocytes with an IC50 of 0.55 nM. Ascomectin inhibits calcineurin by FKBP12-FK520 the formation of the calcineurin ternary complex with an IC50 of 49 nM. FK520 also accelerates the rate of nerve repair and also promotes neurite outgrowth. Ascomcin exhibits an antimalarial effect by inhibiting the chaperone activity of two different functional proteins. |
| In vivo study | Ascomectin (3.2 mg/kg, intramuscular injection) significantly prolonged the survival rate of skin graft rats. Ascomectin, at 50 or 100 μm, exerted a resistant effect on the spasm induced by picrotoxin injected into the rat hippocampus. |

Tacrolimus Imprity 6 - Use
Open Data Verified Data
changchuanmycin is a microbial source of fungicides, with root absorption, but no leaf absorption conduction. It inhibited the spore germination and mycelial growth of Botrytis cinerea. The field efficacy test showed that it had good control effect on tomato gray mold, the dosage (active ingredient) was 75~112.5g/hm2, diluted with water, usually added water 75kg, after mixing evenly foliar spray. The use period is the early stage of the disease of tomato gray mold (tomato in a tower flowering fruit period), generally continuous spraying 2~6 times, depending on the disease, the interval of 7d spraying 1 time. Laboratory tests found that changchuanmycin on maize leaf blight, rice blast, anthracnose, powdery mildew, Sclerotinia sclerotiorum, downy mildew and other crop fungal diseases also have good control effect.

Tacrolimus Imprity 6 - Reference Information
| agricultural antibiotic | changchuan mycin is a macrolide agricultural antibiotic independently created and developed by Shanghai Institute of Pesticides. It is a biological pesticide and can effectively control tomato gray mold, Cucumber gray mold, corn spot and other fungal diseases of crops. China has historically approved the following four Changchuanmycin products for temporary registration, but as of the end of June 2019, none of them have been transferred to official registration. Therefore, according to the relevant provisions of the "Pesticide Management Regulations", the changchuan mycin products currently sold on the market in my country are all fake pesticides. |
| use | the fungicide has good control effect on cucumber gray mold, corn spot disease, sclerotinia sclerotiorum, powdery mildew and other fungal diseases, can be widely used in strawberry, tomato, cucumber and other cash crops, and can replace carbendazim, thiophanate methyl, sukeling and other pesticides with serious resistance. |
| biological activity | Ascomycin (FK520, FR 900520, Immunomycin), a FK-506 analog, is a neutral macrolide immunosuppressant that can prevent rejection after organ transplantation. |
| Target | Value |
| calcineurin phosphatase | 49 nM |
