Product Overview
Gemcitabine HCL  is a pyrimidine nucleoside analog with potent antitumor activity. As a DNA synthesis inhibitor, it disrupts cancer cell proliferation by blocking DNA replication and repair, triggering cell cycle arrest and apoptosis. Widely used in chemotherapy regimens, it targets multiple solid tumors and is a cornerstone in oncology research and treatment.
Key Specifications
Purity: ≥98% (HPLC), typically 99%+
Appearance: White to off-white crystalline powder
Solubility: Soluble in water (19 mg/mL at 25°C); slightly soluble in methanol; practically insoluble in
Storage: Desiccate, protect from light, store at -20°C for long-term stability
Quality Control: Compliant with USP/EP standards; COA, HPLC, NMR, and MS data available
Mechanism of Action
Gemcitabine HCl exerts cytotoxic effects via two active metabolites:
dFdCDP: Inhibits ribonucleotide reductase, depleting deoxyribonucleotide pools required for DNA synthesis.
dFdCTP: Incorporates into DNA strands, blocking chain elongation and inducing DNA damage.
It specifically targets S-phase cells and blocks G1-to-S phase transition, maximizing antitumor efficacy.
Applications
Oncology Treatment: First-line therapy for pancreatic cancer, non-small cell lung cancer (NSCLC), breast cancer, ovarian cancer, and bladder cancer.
Combination Therapy: Synergizes with platinum-based s (cisplatin), taxanes, and targeted therapies to enhance treatment response.
Research Use: Essential reagent for cancer cell biology, resistance studies, and antitumor development.
