Description

Lanatoside B is a purified cardiac glycoside compound derived from *Digitalis lanata*, known for its specific pharmacological activity. This high-purity reference standard is critical for research and development in cardiovascular drug discovery and analytical method validation. It is primarily utilized by pharmaceutical R&D laboratories, analytical testing facilities, and academic institutions focusing on cardiac pharmacology and natural product chemistry.

Application

• Pharmaceutical Reference Standard: Serves as a primary standard for the identification, purity assay, and quantification of related cardiac glycosides in drug substances and finished products using HPLC, LC-MS, or TLC.
• Biochemical Research: Used in studies investigating the mechanism of action of cardiac glycosides on sodium-potassium ATPase (Na⁺/K⁺-ATPase) and their effects on myocardial contractility.
• Analytical Method Development: Essential for developing and validating chromatographic and spectroscopic methods for the analysis of *Digitalis* extracts and derived pharmaceuticals.
• Pharmacology & Toxicology Studies: Employed in *in vitro* and *in vivo* research models to study therapeutic efficacy, pharmacokinetics, and safety profiles of cardiac glycosides.
• Quality Control in Manufacturing: Acts as a system suitability standard in the quality control of digoxin, digitoxin, and other related cardiac drug manufacturing processes.
