Corosolic acid and its derivatives targeting MCCC1 against insulin resistance and their hypoglycemic effect on type 2 diabetic mice.

Corosolic acid (CA), a natural triterpenoid, exhibits various biological activities and is often called as plant-derived insulin due to its significant hypoglycemic effects, making it especially beneficial for individuals with diabetes or high blood glucose levels. However, CA has notable in vitro toxicity, low water solubility, and poor pharmacokinetic properties. To address these limitations, a series of CA derivatives were synthesized, resulting in the identification of derivative H26, which demonstrates a significantly enhanced hypoglycemic effect, reduced toxicity, and improved pharmacokinetic characteristics compared to CA.

Menstrual Blood-Derived Endometrial Stem Cells Ameliorate Ovarian Senescence by Relieving Oxidative Stress-Induced Inflammation.

Senescence is a degenerative process that occurs with ageing, and in the female reproductive system, senescence occurs earlier in the ovaries than in other tissues and organs, which implies a decrease in oocyte quality and exhaustion of the primordial follicular pool, leading to impaired ovarian function and an inability to maintain normal fertility. Unfortunately, the development of curative and effective treatments for ovarian senescence is still a considerable challenge. Currently, mesenchymal stem cells (MSCs)-based therapies for treating various refractory diseases, especially ovarian dysfunction, have been extensively studied and confirmed.
