Ulipristal

SKU: orb1300531

Description

Ulipristal acetate is a selective progesterone receptor modulator (SPRM) used for emergency contraception. It is widely employed in reproductive biology research to study progesterone receptor signaling, with applications in both in vitro receptor binding assays and in vivo models of uterine function.

Bioactivity

• In Vivo:
  Based on clinical trials, ulipristal acetate seems to be a reasonably tolerable and effective method of emergency contraception when used within 120 hours of intercourse. Ulipristal acetate is at least as effective as LNG when used within the first 72 hours after unprotected intercourse. However, ulipristal acetate may be more effective than LNG when used between 72 to 120 hours after unprotected intercourse, extending the window of opportunity for emergency contraception.
• In Vitro:
  Ulipristal acetate has partial agonistic as well as antagonistic effects on the progesterone receptor. It also binds to theglucocorticoid receptor, but has no relevant affinity to the estrogen, androgen and mineralocorticoid receptors.
