NEW COMPOUNDS HAVING A SPIRO CHIRAL CARBON, PROCESS FOR PREPARING THE SAME AND PHARMACEUTICAL COMPOSITION COMPRISING THE SAME

摘要

PURPOSE: A novel compound having spiro chiral carbon skeleton is provided to suppress mastocyte differentiation and fatty acid synthesis and use in treating osteoporosis, fatty liver, and obesity. CONSTITUTION: A novel compound having spiro chiral carbon skeleton is denoted by chemical formula 1. A method for preparing the compound of chemical formula 1 comprises: a step of cutting and drying Phorbas sp. and extracting with C1-C4; a step of dividing the extracting with water and methylene chloride to remove solvent of organic layer; a step of distributing with mixture solution of normal hexane, methanol, and water; a step of removing solvent of methanol layer; and a step of performing chromatography to obtain fraction.
