Abstract
The invention relates to the field of compound antibacterial sterilization, and particularly discloses perilla oxycarbonyl ethyl propionate and application thereof, wherein the specific chemical structural formula of the perilla oxycarbonyl ethyl propionate is shown as the following formula:
Description
Technical Field
The invention relates to the field of compound antibiosis and sterilization, and in particular relates to a novel compound of perilla oxycarbonyl ethyl propionate and application thereof.
Background
With the gradual transition of agricultural economy from extensive growth mode to intensive mode in China, the agricultural product processing industry rises rapidly and develops strongly, becoming the 'secondary yield economy' in the agricultural reproduction process. Agricultural products, especially fresh agricultural products, have high water content and rich nutrition, are easy to rot and deteriorate, and if sterilization treatment is not performed in time after delivery, the commodity characters are difficult to maintain in the circulation process, so that a large amount of rot is easy to occur, and serious loss is caused. At present, the yield of agricultural products, particularly fruits and vegetables, in China is high in the world ranking list, but the loss rate of agricultural products produced in China from farmlands to dining tables every year is up to 25% -30%, while the loss rate of agricultural products in developed countries is generally controlled to be below 5%, and the main reason is that the postpartum sterilization technology of agricultural products in China is relatively conservative and lagged behind. Meanwhile, in investigation, the current commonly used postpartum sterilization dosage forms including carbendazim, benomyl, thiabendazole and other pesticides have the risk of secondary pollution,
perilla alcohol is a small molecular substance naturally existing in various plants such as orange, cherry, mint, bergamot, ginger grass, lavandula angustifolia and the like in a free state or in an ester form, and is a monoterpene compound produced by metabolic pathways of plant formaldehyde and valeric acid. The perillyl alcohol has the bactericidal effect and is a bactericide safe to human. Perillyl alcohol has been approved by the U.S. FDA as a food additive. With the research, the application of the perilla alcohol in the fields of medicines, spices, daily cosmetics and the like is increasingly wide. The perillyl alcohol is a lead compound with potential development value, and is an important way for obtaining a compound with higher bactericidal activity by designing and synthesizing a perillyl alcohol derivative based on the structure of the perillyl alcohol and researching the bactericidal activity of the perillyl alcohol derivative.
Disclosure of Invention
One of the purposes of the invention is to disclose a compound of perilla oxycarbonyl ethyl propionate, the structure of which is shown as the formula:
the second purpose of the invention is to disclose the application of the compound in the bactericide for the postpartum agricultural products.
Experiments prove that the compound has obvious bactericidal activity, has direct control effect on bacteria of agricultural products after delivery, and can be prepared into bactericide of agricultural products after delivery.
The invention also discloses a drug for preventing and treating agricultural germs, which takes the compound as an active ingredient.
When needed, one or more carriers acceptable in bactericides can be added into the medicine, the carriers comprise conventional excipients, diluents, fillers and the like in the bactericides, and the prepared medicine is also various in dosage forms, and can be powder, water aqua, granules and the like.
The germs mentioned in the application or the medicament of the invention are penicillium expansum, pseudomonas and botrytis cinerea.
The invention has the following beneficial effects:
the perilla oxycarbonyl ethyl propionate provided by the invention has a high-efficiency sterilization effect and is safe to human beings, the compound has a direct and good prevention and treatment effect on postpartum germs of agricultural products, can be prepared into a bactericide for the postpartum agricultural products, and has a practical application value in agricultural production.
Detailed Description
The present invention will be further illustrated with reference to the following specific examples, but the present invention is not limited to the following examples. The method is a conventional method unless otherwise specified. The materials are commercially available from the open literature unless otherwise specified.
Example 1 preparation of Perilla oxo-carbonyl Ethyl propionate
The synthetic route is shown as the following formula:
a100 mL three-necked flask was charged with 1.52g (10mmol) of perillyl alcohol, 4.86g (30mmol) of carbonyldiimidazole and 20mL of tetrahydrofuran, refluxed for 3 hours, filtered, washed with methylene chloride and water in this order, dried over anhydrous magnesium sulfate, and rotary-evaporated to obtain a white viscous substance, which was charged into a 50mL three-necked flask, followed by addition of 1.42g (12mmol) of ethyl lactate and 20mL of N, N-dimethylformamide and stirring at 90 ℃ for 6 hours. Adding into a separating funnel containing 50mL of dichloromethane and 50mL of water, separating, washing an organic phase with water and a saturated sodium chloride solution in turn, performing rotary evaporation concentration, and performing column chromatography separation and purification to obtain 2.16g of colorless liquid with the yield of 73%.
The product is characterized by nuclear magnetic hydrogen spectrum and nuclear magnetic carbon spectrum.

Example 2 biological Activity of Compounds of the invention against postpartum pathogens of agricultural products
Under aseptic conditions, the perillyl alcohol, the positive control carbendazim and the compound obtained in example 1 are dissolved in 1mL of DMF, and the solution is diluted to 10mg/L by adding sterile water for later use.
An appropriate amount of spores were picked from strains of Penicillium expansum, Pseudomonas sp, and Botrytis cinerea, inoculated on sterilized PDA medium, and activated at 25 ℃ for 8 days. 5mL of sterile water was added to the tube, and the spores were scraped off using a sterile inoculating loop to prepare a spore suspension. 200 μ L of spore suspension was pipetted onto fresh PDA plates and incubated at 25 ℃ for 7 days for use.
PDA medium was dissolved and cooled, 10mL of 10mg/L perillyl alcohol, carbendazim and the compound solution obtained in example 1 were added, and the medium was poured into a medium having a diameter of 15mm, and a medium containing an equal amount of sterile water was used as a blank.
Using a 6 mm-diameter sterile puncher to respectively punch bacterial blocks of penicillium expansum, pseudomonas and botrytis cinerea which have been cultured for 7 days, placing the bacterial blocks in the center of the culture dish with the medicament, culturing at 25 ℃, measuring the increase of the diameter of bacterial plaque after 3 days, and calculating the inhibition rate.
Inhibition rate ═ [ (increase in plaque diameter of blank control-increase in plaque diameter of treated group)/increase in plaque diameter of blank control ] × 100%
The test results are shown in Table 1.
