Industrial Applications of BQ-3020
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Research | Research tool as a vasoconstrictor | Synthesized via chemical synthesis for in vitro or in vivo studies to investigate its effects on the cardiovascular system |
| Biological Research | Exploration of endothelin receptor specificity and function | Produced using solid-phase or peptide synthesis techniques, followed by purification and structural verification |
| Pharmacology | Investigation of disease mechanisms associated with endothelin | After obtaining the pure compound via organic synthesis, applied in cell culture or animal models to assess pharmacological activity |
| Cardiovascular Disease Research | Study of potential therapeutic targets for cardiovascular diseases such as hypertension | Synthesized through defined chemical reaction steps to obtain the required peptide sequence, followed by biological activity testing |
Manufacturing Quality Control of BQ-3020
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Identity | HPLC-MS | Combines high-performance liquid chromatography separation with mass spectrometry detection to confirm molecular weight and sequence-specific fragmentation pattern. |
| Assay (Purity) | RP-HPLC with UV detection | Quantifies main component peak area relative to a qualified reference standard using reversed-phase chromatography and ultraviolet absorbance at 214 nm. |
| Related Substances | RP-HPLC with gradient elution | Separates and quantifies structurally related impurities (e.g., deletion sequences, oxidation products) using optimized C18 column and mobile phase gradient. |
| Water Content | Karl Fischer Titration | Measures trace water by coulometric or volumetric titration based on iodine consumption in a pyridine-methanol solvent system. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., acetonitrile, DCM, DMF) using gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-MS | Quantifies trace elemental impurities (e.g., Pb, Cd, Ni, Cu) via inductively coupled plasma mass spectrometry after acid digestion. |
| Endotoxin | LAL Assay | Measures bacterial endotoxin using Limulus amebocyte lysate reagent, where endotoxin triggers enzymatic cascade leading to gel formation or colorimetric signal. |
| Bioburden | Membrane Filtration and Plate Count | Determines viable microbial load by filtering sample, rinsing, and culturing on tryptic soy agar under aerobic conditions for colony enumeration. |
| Peptide Content (by Nitrogen) | Elemental Analysis (CHNS) | Determines total nitrogen content via high-temperature combustion and thermal conductivity detection, converted to peptide mass using average nitrogen factor. |
| Optical Rotation | [alpha]D Measurement | Measures specific rotation of solution using polarimeter at 589 nm to confirm chiral integrity and batch-to-batch consistency. |
| pH (1% w/v solution) | Potentiometric pH Measurement | Determines hydrogen ion activity in aqueous solution using calibrated glass electrode and pH meter. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of solid or solution against defined standards under controlled lighting and against white/black backgrounds. |
