Tamoxifenmolecular weight The term "tamoxifen citrate peptide" is unusual, as tamoxifen citrate is a well-established pharmaceutical compound, not typically categorized alongside peptides. However, this search may arise from research exploring the intersection of tamoxifen's mechanisms with peptide-based therapies or from an interest in specific research chemicalsTamoxifen Citrate (ICI 46474)is an orally active, selective estrogen receptor modulator(SERM) which blocks estrogen action in breast cells and can activate .... Tamoxifen citrate is primarily known as a selective estrogen receptor modulator (SERM) widely used in the treatment and prevention of estrogen receptor-positive breast cancer2025年4月23日—It works by binding to estrogen receptors and blocking estrogen activity in certain tissues—most notably in the breast tissue.. Its action involves blocking estrogen's effects in breast tissue, thereby inhibiting tumor growth and inducing apoptosis.
Tamoxifen citrate is a non-steroidal, orally active antiestrogen that functions as a selective estrogen receptor modulator (SERM). This means it can act as an antagonist in some tissues, like breast tissue, by blocking estrogen receptors, and as an agonist in others, such as the endometrium. This dual action is crucial to its therapeutic applications. It's widely recognized for its role in the adjuvant treatment of early breast cancer in women with estrogen receptor-positive tumors, and it's also used to prevent breast cancer in certain high-risk individualsNOLVADEX - (Tamoxifen Citrate) - accessdata.fda.gov.
The molecular weight of tamoxifen citrate is approximately 563MW 563.65 g/mol, Purity >99%. Competitive estrogen receptor antagonist and partial agonist. Inhibits estrogen dependent gene transcription and tumor growth..65 g/molTamoxifen Citrate | Estrogen receptor antagonist. High purity, often exceeding 99%, is essential for its use in pharmaceutical testing and research. Beyond its primary role as an antiestrogen, tamoxifen has also been identified as a protein kinase C (PKC) inhibitor, capable of inducing apoptosis in various cancer cell lines.
The primary application of tamoxifen citrate is in hormonal therapy for breast cancer.Tamoxifen citrate is a well-known selective estrogen receptor modulator(SERM) primarily utilized in the treatment of hormone receptor-positive breast cancer. By competitively binding to estrogen receptors, it prevents estrogen from stimulating the growth of hormone-sensitive tumors2025年4月23日—It works by binding to estrogen receptors and blocking estrogen activity in certain tissues—most notably in the breast tissue.. This mechanism makes it a cornerstone treatment for estrogen receptor-positive (ER+) breast cancers, a common subtype.
In research settings, tamoxifen citrate is used to study estrogen receptor signaling pathways, cancer cell proliferation, and the development of resistance to hormonal therapies. Its ability to inhibit sterol biosynthesis and induce apoptosis are also areas of active investigation.2006年10月5日—Tamoxifen citrate is a type of hormone therapycalled a selective estrogen receptor modulator (or SERM). It works by binding to estrogen receptors. The compound is available from various suppliers for pharmaceutical testing and research, often as a reference standard to ensure accurate results in laboratory experiments.
The inclusion of "peptide" in the search term "tamoxifen citrate peptide" is the most intriguing aspect. While tamoxifen citrate itself is a small molecule drug, research has explored its combination with peptide-based delivery systems or its interaction with peptide signaling pathways.Tamoxifen Citrate | Estrogen receptor antagonist For example, studies have investigated peptide-derived compounds that can prevent tumor growth, with some research indicating that both peptides and tamoxifen can inhibit estrogen-receptor-positive breast cancer xenograftsTamoxifen . citrate.
It's also possible that the term "peptide" is being used loosely or in error. In some contexts, particularly within bodybuilding or performance enhancement circles, certain compounds might be mislabeled or inaccurately associated with peptides. However, in a scientific or medical context, tamoxifen citrate is definitively not a peptide. Peptides are short chains of amino acids, whereas tamoxifen citrate is a synthetic organic molecule.
For those encountering "tamoxifen citrate peptide" in a research context, it's crucial to differentiate. The core entity is tamoxifen citrate, a potent SERM.MW 563.65 g/mol, Purity >99%. Competitive estrogen receptor antagonist and partial agonist. Inhibits estrogen dependent gene transcription and tumor growth. Any mention of "peptide" likely refers to:
* Delivery Systems: Tamoxifen citrate loaded into peptide-conjugated nanoparticles or polymersomes for targeted delivery.作者：JA Bennett·2002·被引用次数：66—Both peptide and tamoxifen prevented growth of estrogen-receptor-positive MCF-7 and T47D human breast cancer xenografts.
* Synergistic Therapies: Research exploring the combined effects of tamoxifen citrate with specific peptides that may enhance anti-cancer activity.
* Misclassification: An incorrect categorization of tamoxifen citrate within the broader landscape of therapeutic agents.Tamoxifen (Citrate) - MedChem Express
When sourcing tamoxifen citrate for research or pharmaceutical purposes, purity is a critical factor.Tamoxifen is an estrogen receptor antagonist(IC50 = 45 nM for the rabbit receptor). It reduces the proliferation of MCF-7 breast cancer cells when used at ... Reputable suppliers emphasize high purity levels (eDefinition of tamoxifen citrate - NCI Dictionary of Cancer Terms.g.Tamoxifen Citrate - Antiestrogen drug - APExBIO, >99%) and provide analytical data to support their claimsTamoxifen Citrate 20mg/ml @ 30ml. This is essential for ensuring reproducible experimental results and for meeting regulatory standards if the compound is intended for further development.
In summary, while tamoxifen citrate is a well-defined pharmaceutical agent with significant therapeutic applications, its association with "peptide" likely stems from advanced research into drug delivery or combination therapies, or potentially from misinterpretations of its classification. The core function and identity of tamoxifen citrate remain firmly rooted in its role as a selective estrogen receptor modulator for cancer treatment.
