The present disclosure relates to novel compounds, pharmaceutical compositions, and methods for treating or preventing microbial infection caused by parasites or bacteria, such as Plasmodium falciparum or related Plasmodium parasite species and Mycobacterium tuberculosis or related Mycobacterium bacteria species. The compounds are α,β-unsaturated analogs of fosmidomycin and can inhibit deoxyxylulose phosphate reductoisomerase (Dxr) in many microbes, such as P. falciparum.

nonmevalonate pathway (NMP) of isoprene biosynthesis has been examined as a source of new antibiotics with novel mechanisms of action. Dxr is the best studied of the NMP enzymes and several reports have described potent Dxr inhibitors. Many of these compounds are structurally related to natural products fosmidomycin and FR900098, each bearing retrohydroxamate and phosphonate groups. We synthesized a series of

fosmidomycin, a natural product that inhibits DXR in P. falciparum. All compounds were evaluated as inhibitors of P. falciparum. The most promising compound, 18a, displays on-target, potent inhibition against the growth of P. falciparum (IC50 = 13 nM) without significant inhibition of HepG2 cells (IC50 > 50 μM). 18a was also tested in a luciferase-based Plasmodium berghei mouse model of malaria and showed exceptional

An efficient method for the preparation of backbone-substituted imidazolinium salts for use as N-heterocyclic carbene ligands, e.g., for organometallic catalysts is provided. These functionalized N-heterocyclic carbene ligands are used to prepare solid-supported catalysts, e.g., for olefin metathesis.
