Postdoctoral researcher at the Nanomalaria Research Group (Ref: PD-XF)

Introduction to the vacant position:

The Nanomalaria Group is looking for a highly qualified researcher with a synthetic chemistry background and expertise in biological evaluations, particularly in Plasmodium falciparum cultures and the cellular biology of malaria parasites. The contract will be within the framework of one of the research lines of the Nanomalaria Group, whose objective is the characterization of the inhibition of protein aggregation as a novel mode of action of future antimalarial drugs.

The available arsenal of antimalarial drugs is insufficient to progress towards eradication of the disease, a scenario that is worsened by the rampant evolution of resistance by Plasmodium. This situation calls for immediate efforts to discover new antimalarials of easy and cost-affordable production, having several molecular targets in the pathogen and acting through new antiparasitic mechanisms not shared by currently used drugs.

The bis(styrylpyridinium) salt YAT2150 has a number of properties that make it highly interesting as antimalarial drug, namely: (i) its synthesis is easy and rapid (only two steps), which results in an attractive activity/cost ratio taking into account that its main clinical deployment would be in the low per capita income regions where malaria is endemic; (ii) its mode of action (inhibition of protein aggregation in the parasite) presumably targets multiple proteins, which would likely prevent a rapid resistance evolution by the pathogen, as opposed to most other current antimalarial drugs which target products of one or a few genes; (iii) it belongs to an unexplored chemical family where no other antimalarial has been described up to date, which will prevent the adaptation by the parasite of preexisting resistance mechanisms to currently used drugs; (iv) our preliminary data suggest that YAT2150 might be active against all Plasmodium species causing human malaria, which would make of this drug a pan-malaria treatment; (v) this molecule fluoresces when interacting with its molecular targets in Plasmodium cells, which makes of it a theranostic agent; (vi) it targets (binds) all stages of the parasite in the vertebrate host and in the mosquito vector; (vii) the compound has a long shelf life (months) at room temperature; (viii) it has a low parasite in vitro growth half-maximal inhibitory concentration (IC50) below 100 nM. These characteristics place YAT2150 as a highly promising model for a new generation of antimalarial drugs for the post-artemisinin era, since resistances to this last drug (on which the main current therapeutic approaches are based) are widespread in Asia, and resistance markers have been already identified in Africa and South America.

However, the 50% cytotoxic concentration (CC50) of YAT2150 for human cells results in a selectivity index (SI: CC50/IC50) below 100. The perspectives of a successful clinical development of YAT2150 as antimalarial drug will improve significantly if the SI can be incremented to values above 100.

Main objective of the project: To obtain YAT2150 derivatives with a sufficiently favorable selectivity index in order to allow this new family of antimalarial drugs entering the preclinical development pipeline.

Specific objectives of the project: (i) To synthesize YAT2150 chemical derivatives through the selective modification of different chemical groups in the parent molecule. These derivatives will be initially evaluated for their activity as inhibitors of protein aggregation in vitro and in live Plasmodium falciparum cultures. (ii) Characterization of the activity of the derivatives in in vitro P. falciparum cultures and in human cell cultures in order to obtain the respective IC50 and CC50 and calculate the corresponding SI. Finally (iii), for the derivatives with higher SI, in vivo assays in a murine model of malaria will assess the potential of those compounds for entering a preclinical development process.

The successful candidate will develop research involving:

  • Synthesis of YAT2150 derivatives
  • Antiplasmodial in vitro activity characterization of YAT2150 derivatives
  • In vivo activity characterization of YAT2150 derivatives in a murine model of malaria
