The application discloses a
serine nano-
drug for treating
preeclampsia by targeting placental
oxidative stress, which can pass through the placental barrier by changing the particle size, thereby increasing the local concentration of
serine in the
placenta to achieve the purpose of relieving placental
oxidative stress and treating
preeclampsia. The placental barrier is the barrier between the placental villus tissue and the uterine blood sinus, and is an important basis for maintaining
normal pregnancy. However, the placental barrier also hinders the entry of drugs into the
placenta, affecting the
treatment effect of drugs on placental diseases, such as
preeclampsia, fetal intrauterine growth restriction and the like. The nano-
drug is prepared by using nano-preparation technology to make raw drugs into particles with a nano scale, and has the
advantage of penetrating through the body barrier. The
amino acid involved in
oxidative stress regulation,
serine, is synthesized into nano-serine by using nano technology, so that serine can pass through the placental barrier by changing the particle size of nano-serine, thereby increasing the local concentration of serine in the
placenta, and achieving the purpose of treating preeclampsia by reducing placental oxidative stress.
