Bacteriostatic Water for Injection (BWFI) does not have a specific chemical or development code as it is a sterile diluent. It is commonly referenced in literature for sterile preparation and is primarily known as water with bacteriostatic properties due to the addition of a bacteriostatic agent, typically benzyl alcohol.
As Bacteriostatic Water itself is not a peptide or protein, it does not possess an amino acid sequence. The structure is simply water (H2O), with benzyl alcohol as the bacteriostatic agent.
Bacteriostatic water does not engage in classic receptor-mediated pharmacological actions like peptides or small molecules. However, it serves to maintain sterility in multi-use vials by preventing microbial growth through benzyl alcohol's interaction with microbial membranes.
Solubility: Water is inherently soluble with a density of approximately 1 g/cm3 at 25°C. Benzyl alcohol, the bacteriostatic agent, is present at a concentration of approximately 0.9%. Stability: It is recommended to store at controlled room temperature and, once opened, should be used within 28 days to ensure sterility if stored under appropriate conditions.

Chorionic Gonadotropin; commonly abbreviated as HCG. It is a glycoprotein hormone composed of alpha and beta subunits, predominantly characterized in human pregnancy. No specific research codes or development codes are associated with the basic glycoprotein.
HCG is a heterodimeric protein composed of two non-covalently linked subunits: the alpha subunit (92 amino acids) shared with other hormones like LH, FSH, and TSH, and the beta subunit (145 amino acids) which is unique to HCG. The beta subunit contains distinct segments: H-Trp-Met-Ser-Glu-His-Ile-Thr-Arg-Tyr-Leu-... and features specific disulfide bridges essential for activity and stability.
HCG acts as an agonist to the luteinizing hormone/chorionic gonadotropin receptor (LHCG receptor). Binding of HCG to its receptor activates pathways such as the cAMP/PKA signaling cascade, promoting steroidogenesis. EC50 values are variable based on assay and cellular system but are indicative of potent agonist activity.
HCG is soluble in sterile water at concentrations of 1mg/mL for research applications. Upon reconstitution, the solution must be stored at 2-8°C and is stable for up to 24 hours. Lyophilized HCG remains stable at -20°C until reconstitution.
