Alarelin Acetate Synthetic Peptide
A Targeted GnRH Analogue for Reproductive Hormone Regulation
Product Overview
Alarelin Acetate is a synthetic decapeptide and a potent analogue of Gonadotropin-Releasing Hormone (GnRH) . It is designed to closely mimic the physiological activity of natural GnRH, enabling precise regulation of reproductive hormones. Due to its controlled and predictable biological action, Alarelin Acetate is widely used in reproductive medicine, veterinary and medical research, and hormone-related studies .
CAS Number: 79561-22-1
Quality Standards: In-House / IP / EP / BP
Molecular Type: Synthetic GnRH peptide (decapeptide)
Intended Use: Research, reproductive hormone modulation, and formulation development
Mechanism of Action
Alarelin Acetate acts on the pituitary gland , stimulating the release of:
▸ Luteinizing Hormone (LH)
▸ Follicle-Stimulating Hormone (FSH)
Its activity follows a biphasic hormonal response :
▸ Initial stimulation of LH and FSH secretion
▸ Subsequent downregulation through GnRH receptor desensitization
This mechanism allows Alarelin Acetate to both induce ovulation and suppress gonadal hormone production , depending on dosage and duration of administration.
Key Applications
1.Ovulation Induction and Fertility Control
▸ Trigger ovulation through LH surge induction
▸ Precisely control ovulation timing
▸ Support fertility research and assisted reproductive protocols
Its predictable hormonal response makes it highly valuable where timing and consistency are critical.
2. Management of Hormone-Dependent Conditions
▸ Reduces ovarian estrogen production
▸ Creates a temporary hypoestrogenic state
▸ Helps alleviate symptoms associated with endometriosis and other estrogen-dependent conditions
This controlled suppression is achieved via GnRH receptor desensitization.
3. Research and Experimental Use
▸ Reproductive endocrinology research
▸ Animal studies investigating fertility and hormone signaling
▸ Development and evaluation of new reproductive therapies
Its structural similarity to natural GnRH allows accurate modeling of physiological processes.
Administration and Use Considerations
▸ Typically administered via injection
▸ Dosage and treatment duration depend on intended application
▸ Used under controlled conditions in clinical or research environments
As a synthetic peptide, proper handling, formulation, and storage are essential to maintain stability and activity.
Safety and Tolerability
Alarelin Acetate is generally well tolerated when used appropriately. Possible transient effects may include:
▸ Temporary hormonal fluctuations
▸ Mild symptoms such as hot flashes or mood changes
These effects are typically reversible and related to its hormonal mechanism of action.
Advantages of Alarelin Acetate
▸ High specificity for GnRH receptors
▸ Predictable and controllable hormonal effects
▸ Suitable for both stimulation and suppression protocols
▸ Consistent performance as a synthetic peptide
▸ Compliance with major pharmacopoeial standards
Conclusion
Alarelin Acetate Synthetic Peptide is a powerful and versatile GnRH analogue used for precise regulation of reproductive hormones. Its dual ability to stimulate and suppress gonadotropin release makes it an essential tool in fertility management, hormone-dependent condition treatment, and reproductive research .
With proper formulation and application, Alarelin Acetate continues to support advancements in reproductive science and hormone regulation technologies.
