Dihydropyrimidines formed by a Biginelli reaction possess interesting pharmacological properties such as acting as Heat Shock Protein 70 modulators. Using multifunctionalized Biginelli scaffolds as the primary template and then forming larger heterocyclic molecules via a copper catalyzed amidation reaction, a library can be synthesized.

These novel heterocyclic molecules were designed based on the chemistry of previously identified agents impacting the viability of P. falciparum, the causative agent of malaria. We are now reporting extensions of these projects toward a 2nd generation chemical library.

After completion of the synthesis, the potencies of the derived agents will be examined both in assays that measure P. falciparum viability and in vitro. The in vitro assay will employ purified Plasmodium falciparum heat shock protein 70 isolated from Escherichia coli. The rationale for this assay is that some existing anti-malarial agents inhibit chaperone function, albeit with low specificity.
