Abstract:

This experiment preliminarily confirmed that glycyrtinic acid at the mass concentration of 50-100 μg/mL could significantly inhibit the secretion of triglyceride by 3T3-L1 cells (P<0.01) in a mass concentration-dependent manner. 3T3-L1 cells, as preadipocytes, continue to increase adipocyte proliferation and triglyceride accumulation under exogenous stimulation. They differentiate into mature adipocytes and form adipose tissue. Glycyrrhetinic acid can inhibit the proliferation of preadipocytes and reduce the accumulation of triglycerides, indicating that glycyrrhetinic acid has the effect of inhibiting lipid synthesis and metabolism at the cellular level. Further, through the golden hamsters model, it is confirmed that glycyrrhetic acid at the set mass concentration significantly reduces the area of bilateral sebaceous gland on the abdomen of golden hamsters, reduces the thickness and number of sebaceous glands, inhibites the growth of sebaceous glands and thus reduces the abnormal excessive secretion of sebaceous glands. At the mass concentration of 100 μg/mL, glycyrrhetinic acid significantly regulates the expression of SrebP-1C (P<0.001), TG (P<0.01), K6 (P<0.01), K16 (P<0.01) and IL-6 (P<0.05) in sebaceous glands. It inhibits the SREBP protein activity in sebaceous gland tissue, inhibits sebum synthesis and secretion of triglyceride composition content, and further reduces the cutin formation and keratin K6, K16 expression in cells, which play a role in regulating sebaceous gland growth and oil secretion. Abnormal sebum secretion from sebaceous glands can induce skin health problems such as acne, skin barrier dysfunction and specific dermatitis. Through the above experimental studies, it has been preliminarily confirmed that the single use of glycyrrhetinic acid can effectively inhibit the growth of sebaceous gland spots in golden hamsters and reduce sebum secretion and inflammatory reaction. These results suggest that glycyrrhetinic acid may play a role in regulating oily skin, inhibiting acne, improving skin barrier function and specific dermatitis, and can be used as an active ingredient in skin surgery drugs and functional daily cosmetics that relieve acne and skin inflammation.

Key words: glycyrrhetinic acid, sebaceous gland, golden hamsters, anti-inflammatory
