The pentacyclic triterpene betulin and its oxidized derivative betulinic acid are abundantly present in nature. Both compounds are highly lipophilic due to their lupane scaffold and exhibit limited solubility in typical organic solvents, water, and for example DMF, and DMSO.
However, the compounds are normally highly soluble in pyridine and acetic acid. Betulin and its derivatives possess a wide range of biological and pharmacological activities indicating for example anti-inflammatory, anti-HIV, anti-bacterial, and anti-cancer activities. Ongoing research aims for derivatives with improved therapeutic efficacy by enhancing their poor water solubility.
