Isoprenoid Biosynthesis Inhibitors Targeting Bacterial Cell Growth

We synthesized potential inhibitors of farnesyl diphosphate synthase (FPPS), undecaprenyl diphosphate synthase (UPPS), or undecaprenyl diphosphate phosphatase (UPPP), and tested them in bacterial cell growth and enzyme inhibition assays. The most active compounds were found to be bisphosphonates with electron-withdrawing aryl-alkyl side chains which inhibited the growth of Gram-negative bacteria (Acinetobacter baumannii, Klebsiella pneumoniae, Escherichia coli, and Pseudomonas aeruginosa) at ~1–4 μg mL?1levels. They were found to be potent inhibitors of FPPS; cell growth was partially “rescued” by the addition of farnesol or overexpression of FPPS, and there was synergistic activity with known isoprenoid biosynthesis pathway inhibitors. Lipophilic hydroxyalkyl phosphonic acids inhibited UPPS and UPPP at micromolar levels; they were active (~2–6 μg mL?1) against Gram-positive but not Gram-negative organisms, and again exhibited synergistic activity with cell wall biosynthesis inhibitors, but only indifferent effects with other inhibitors. The results are of interest because they describe novel inhibitors of FPPS, UPPS, and UPPP with cell growth inhibitory activities as low as ~1–2 μg mL?1.
Highly efficient green synthesis of α-hydroxyphosphonates using a recyclable choline hydroxide catalyst

Choline hydroxide has been found to be an efficient basic ionic liquid catalyst for the synthesis of α-hydroxyphosphonates. Hydrophosphonylation of aldehydes was performed via the nucleophilic addition of diethylphosphite to aldehydic carbonyl compounds, in the presence of choline hydroxide under neat as well as solvent conditions. A wide array of substrates, including aromatic, fused aromatic, and heterocyclic aldehydes, were efficiently converted to their corresponding products in good yields. This protocol provides an alternative method for the straightforward synthesis of α-hydroxyphosphonates in high yields.
