Continuous-flow synthesis of the anti-malaria drug artemisinin
24 Apr 2024 | Contributor(s):: Lévesque, François, Seeberger, Peter H
Malaria is a serious global health issue. Artemisinin combination treatments are the first-line drugs, but supplies are limited because artemisinin is obtained solely by extraction from Artemisia annua. A continuous-flow process that converts dihydroartemisinic acid into artemisinin (see scheme)...

Technoeconomic optimisation and comparative environmental impact evaluation of continuous crystallisation and antisolvent selection for artemisinin recovery
09 Jun 2023 | Contributor(s):: Jolliffe, HG, Gerogiorgis, DI
Systematic nonlinear optimisation is a valuable tool towards evaluating the performance of conceptual Continuous Pharmaceutical Manufacturing (CPM) flowsheets. This study considers total cost minimisation of multiple plausible design choices and eight candidate antisolvents for the continuous...
