Reaction of artemisinin with haemoglobin: implications for antimalarial activity.
Elucidation of the principal targets of the action of the antimalarial drug artemisinin is an ongoing pursuit that is important for understanding the action of this drug and for the development of more potent analogues. We have examined the chemical reaction of Hb with artemisinin. The protein-bound haem in Hb has been found to react with artemisinin much faster than is the case with free haem....
متن کاملThe structure-activity relationship of the antimalarial ozonide arterolane (OZ277).
The structure and stereochemistry of the cyclohexane substituents of analogues of arterolane (OZ277) had little effect on potency against Plasmodium falciparum in vitro. Weak base functional groups were not required for high antimalarial potency, but they were essential for high antimalarial efficacy in P. berghei-infected mice. Five new ozonides with antimalarial efficacy and ADME profiles sup...
متن کاملStructure–Activity Relationship Studies of Pyrrolone Antimalarial Agents
Previously reported pyrrolones, such as TDR32570, exhibited potential as antimalarial agents; however, while these compounds have potent antimalarial activity, they suffer from poor aqueous solubility and metabolic instability. Here, further structure-activity relationship studies are described that aimed to solve the developability issues associated with this series of compounds. In particular...
متن کاملQuantitative structure-activity relationship of some pesticides.
Herbicides (benzodiazepinediones), insecticides (dioxatricyclododecenes) and larvicides (N-oxalyl derivatives of tebufenozide) have been quantitatively investigated to explore the relationship between the molecular structure and their biological activity using molecular operating environment (MOE) software. The study provides good predictive models, cross-validated by leave-out-one method (Loo)...
متن کاملExtracellular heme enhances the antimalarial activity of artemisinin.
Artemisinin exerts the antimalarial activity through activation by heme. The hemolysis in malaria results in the elevated levels of plasma heme which may affect the activity of artemisinin. We hypothesized that the extracellular heme would potentiate the antimalarial activity of artemisinin. Hemin (ferric heme) at the pathologic concentrations enhanced the activity of artemisinin against Plasmo...
