Abstract
More than 40% of the world's population, across 105 countries, live in malaria endemic areas. It is estimated that about 500million cases of malaria and half a million deaths occur per year. Herein, we demonstrate the biological activity of indole-3-glyoxyl tyrosine against Plasmodium falciparum, which is the causal agent of the most virulent form of malaria in humans. We developed an efficient synthesis of indole-3-glyoxyl tyrosine derivatives, which were then used as key intermediates in the synthesis of functionalized indole-3-glyoxyl biphenyl tyrosines. In biological testing, the compounds exhibited a parasite growth inhibition of over 85%. A cell viability assay showed low cytotoxicity against human cells, with no significant changes in cell viability, making these compounds potential antimalarials.
