Description

(3R,4S,5S,6R,7R,9R,11R,12R,13R,14R)-4-[(2S,4R,5S,6S)-4,5-dihydroxy-4,6-dimethyl-oxan-2-yl]oxy-6-[(2S,3R,4S,6R)-4-dimethylamino-3-hydroxy-6-methyl-oxan-2-yl]oxy-14-ethyl-7,12,13-trihydroxy-3,5,7,9,11,13-hexamethyl-1-oxacyclotetradecane-2,10-dione is a complex macrolide compound of significant interest in pharmaceutical research and development. This molecule matters for its structural complexity and potential as a key intermediate or active pharmaceutical ingredient (API) in the synthesis of advanced therapeutics. It is primarily needed by research institutions, pharmaceutical companies, and fine chemical manufacturers engaged in the development of novel antibiotics, anti-cancer agents, and other specialized bioactive compounds.

Application

• Pharmaceutical Intermediate: Serves as a critical building block in the multi-step synthesis of novel macrolide antibiotics and other complex therapeutic agents.
• Biochemical Research: Used as a reference standard or probe in studies investigating macrolide biosynthesis, mode of action, and structure-activity relationships (SAR).
• API Development: Acts as a precursor or the core structure in the research and development of new Active Pharmaceutical Ingredients (APIs) targeting bacterial infections.
• Fine Chemical Synthesis: Employed in advanced organic synthesis for constructing complex molecular architectures with specific stereochemistry.
• Academic Research: Utilized in university and institutional labs for methodological development in total synthesis and natural product chemistry.
