  • Synthesis and hydrolytic stability of cyclic phosphatidic acids: implications for synthetic- and proto-cell studies
    作者:Veronica Egas Ortuno、Sunil Pulletikurti、Kollery S. Veena、Ramanarayanan Krishnamurthy
    DOI:10.1039/d2cc00292b
    日期:——
    Cyclic phosphatidic acids (cPAs) are bioactive compounds with therapuetic potential, but are in short supply. We describe a robust synthesis of cPAs employing an efficient cyclophosphorylation procedure and report on their hydrolytic properties – which should facilitate the study of their biological properties and as plausible proto- and synthetic-cell components.

  • Kinetics of enzymatic synthesis of isopropylidene glycerol esters by goat pregastric lipase
    作者:Douglas T. Lai、Norikatsu Hattori、Charmian J. O’Connor
    DOI:10.1007/s11746-999-0075-6
    日期:1999.7
    AbstractThe goat pregastric lipase‐catalyzed esterification of isopropylidene glycerol with caproic acid, to form isopropylidene glycerol caproate, followed a ping pong bi bi mechanism incorporating an acyl‐enzyme intermediate. The maximum rate was estimated to be 96 µmol min−1 mg−1 in isooctane at 35°C, and the Michaelis‐Menten constants for isopropylidene glycerol and caproic acid were 0.23 and 0.32 M, respectively. The catalyzed rate also correlated well with the partition coefficient of caproic acid between the organic and aqueous phases. The results suggest that the desolvation energy of the substrate from the bulk medium to the active site of the enzyme dominates the reaction rate for the enzyme‐catalyzed reaction in organic media.

  • Optimized double kinetic resolution for the preparation of (S)-solketal
    作者:Eero Vänttinen、Liisa T Kanerva
    DOI:10.1016/s0957-4166(97)00057-8
    日期:1997.3
    The lipase AK (lipase from Pseudomonas sp.)-catalysed alcoholysis of racemic solketal (2,2-dimethyl-1,3-dioxolane-4-methanol) esters and acylation of solketal in organic solvents proceeded with E=20-25. This enabled the preparation of the more reactive (S)-enantiomer with more than 30% total isolated yield (based on the racemate) and 95% ee by a double kinetic resolution strategy consisting of enzymatic acylation-chemical saponification-enzymatic acylation or enzymatic alcoholysis-enzymatic acylation sequences. Numerical calculations and theoretical plots for the optimal termination conversions for the 1st and 2nd resolution steps as well as for the final yields as the function of E is considered.

  • Enhanced enantioselectivity of Bacillus coagulans in the hydrolysis of 1,2-O-isopropylidene glycerol esters by thermal knock-out of undesired enzymes
    作者:Diego Romano、Francesco Falcioni、Diego Mora、Francesco Molinari、Andreas Buthe、Marion Ansorge-Schumacher
    DOI:10.1016/j.tetasy.2004.12.021
    日期:2005.2
    The enantioselective hydrolysis of different (RS)-1,2-O-isopropylidene glycerol esters has been achieved with whole cells of Bacillus coagulans NCIMB 9365 furnishing the (S)-alcohol as the major enantiomer. The reaction is catalysed by a thermostable cell-bound carboxylesterase and improvement of the enantioselectivity has been achieved by heat treatment of the whole cells, which causes the knock-outs a non-enantioselective competing enzyme. Thermally-treated cells hydrolysed (RS)-1,2-O-isopropylidene glycerol esters with high enantioselectivity, the highest enantiomeric ratio (80-100) being observed for the benzoate. The biocatalyst displayed good stability and could be re-used after filtration for 12 cycles before showing significant loss of activity; repeated biotransformation batches allowed the recovery of 9.55 g/L of enantiomerically pure (S)-isopropylideneglycerol benzoate starting from 24.0 g/L of the racemic mixture.
