Description

[20ξ,(-)]-3β,20,25-Trihydroxy-5α-Lanosta-7,9(11)-Diene-18-Oic Acid γ-Lactone is a highly functionalized lanostane-type triterpenoid derivative, characterized by its unique diene and γ-lactone functionalities. This compound serves as a critical advanced intermediate or reference standard in pharmaceutical research and development, particularly for exploring structure-activity relationships in bioactive natural products. It is primarily needed by research institutions, pharmaceutical R&D laboratories, and fine chemical manufacturers engaged in the synthesis of novel therapeutic agents or the study of sterol biosynthesis.

Application

• Pharmaceutical Intermediate: Key building block for the semi-synthesis of novel steroidal or triterpenoid-based drug candidates targeting inflammation, metabolic disorders, or oncology.
• Biochemical Research: Used as a reference standard or probe molecule in studies of enzyme inhibition, receptor binding, and metabolic pathways involving lanostane derivatives.
• Natural Product Synthesis: Serves as a sophisticated starting material or intermediate in the total synthesis of complex natural products for structure confirmation and analog generation.
• Analytical Standard: High-purity grade material for use as a calibration standard in chromatographic (HPLC, GC) and spectroscopic (NMR, MS) analysis within quality control laboratories.
• Academic Research: Utilized in university and institutional labs for chemical education and fundamental research in organic chemistry and medicinal chemistry.
