Description

9'''-Methyllithospermate B is a specialized bioactive compound derived from lithospermate, a class of polyphenolic compounds found in certain traditional medicinal herbs. This compound is valued for its potential as a key intermediate in pharmaceutical research and development, particularly in the study of cardiovascular and metabolic pathways. It is primarily sought by research institutions and pharmaceutical companies engaged in the development of novel therapeutic agents and high-purity reference standards.

Application

• Pharmaceutical Research & Development: Serves as a critical intermediate or reference standard in the synthesis and study of new drug candidates targeting oxidative stress and inflammation.
• Biochemical Assays: Used as a high-purity standard in analytical methods such as HPLC and LC-MS for method development, validation, and quality control in laboratories.
• Natural Product Chemistry: Employed as a purified compound for studying the structure-activity relationships (SAR) of lithospermate derivatives and their biological effects.
• Academic Research: Utilized in university and institutional labs for pharmacological studies investigating cardioprotective, neuroprotective, or antioxidant mechanisms.
• Preclinical Studies: Acts as a test compound in in vitro and in vivo models to evaluate efficacy, pharmacokinetics, and safety profiles.
