Tunable Enzymatic Synthesis of the Immunomodulator Lipid IVA To Enable Structure–Activity Analysis

“…Unexpectedly, however, the product of this reconstituted system predominantly harbored C 12 hydroxyacyl chains in lieu of C 14 acyl chains. With increasing concentrations of the FabB ketosynthase, it was expected that unsaturated C 14 analogues of Lipid IV A would be the dominant products in the presence of E. coli FabA and FabZ; 17 indeed, this was found to be the case ( Figure 3B).…”

Effect of Biochar on Microbial Growth: A Metabolomics and Bacteriological Investigation in E. coli

“…1,3,[15][16] Moreover, BC has been shown to restore nutrients derived from feedstock by modulating cation exchange capacity (CEC), increasing specific surface area, and influencing hydrophobicity. [10][11]17 Physical and chemical properties of BC increase net nitrogen mineralization, increase nitrification, and enhance denitrification during microbial-mediated transformation of nutrients in soil. 11,18 Microbial activity itself is influenced by BC treatment.…”

One-Pot, Three-Aryne Cascade Strategy for Naphthalene Formation from 1,3-Diynes and 1,2-Benzdiyne Equivalents

“…6 This process can be extended to form higher homologs, including a tetracyne, 10. 7 Therefore, we hypothesized that nucleophile 11, bearing a pendant 1,3-diyne moiety, attacks the 1,2-benzdiyne equivalent 5 to give the benzyne 12 (Figure 1d). Subsequent HDDA reaction produces naphthyne 13, which is then trapped to form product 14.…”
