Product Description
Mechanism of Action
Cyclofenil is a selective estrogen receptor modulator (SERM) that exhibits mixed estrogenic and anti‑estrogenic effects depending on tissue type. It binds ER‑α and ER‑β, modulating transcription of estrogen‑responsive genes. In endocrine systems, it increases gonadotropin release by reducing negative estrogen feedback at the hypothalamus.
Benefits and Advantages
Used in reproductive‑endocrinology research, SERM‑pathway modelling, ER‑binding affinity studies, ovulatory‑cycle simulations and hormone‑feedback investigations.
Side Effects and Risks
Risks include vasomotor symptoms, mood changes, thromboembolic tendencies, hepatic enzyme elevations and hormonal imbalance. Handle with hormone‑modulating agent precautions.
