  • Objective To synthesize a lipophilic prodrug of triptolide (TP) and improve its druggability. Methods Triptolide stearate (TP-SA) was synthesized via the DMAP-catalyzed DCC method and identified by MS, 1H-NMR and 13C-NMR. The shake-flask method was used to study the oil/water partition coefficient. The preparations of TP and TP-SA liposomes and emulsions were compared. Their encapsulation efficiency and stability were investigated. Results TP-SA was synthesized successfully. Its log P in octanol/water system was 2.33. It was difficult to prepare TP liposome or emulsion. By contrast, TP-SA liposome and emulsion can be prepared successfully with the same formulation process. The particle size of TP-SA liposomes were about 90 nm and TP-SA emulsions were about 110 nm. The encapsulation efficiency was above 95%. Their stability were studied at 4℃ and 25℃. The preparation parameters, such as particle size and encapsulation efficiency, had no significant change in a week. Conclusion Triptolide stearate enhanced drug lipophilicity. Its druggability was improved significantly. These data can be used for the TP related drug design and development.
