Abstract
Five new bisabolane sesquiterpenes, a new polyketide, along with seven known compounds, were isolated from endophyte Schizophyllum commune associated with a famous medicinal and edible plant, Gastrodia elata. Most compounds 1-12, and extract indicated antifeedant activities against silkworm with feeding deterrence index (FDI) of 21-85 %, at concentrations of 20 μg/cm2 , 40 μg/cm2 , respectively. Compound 6 indicated obvious insecticidal activity with fatality rate of 60 %, at the concentration of 20 μg/cm2 . Five bisabolane sesquiterpenes, two ergosterols, and a glyceride showed insecticidal synergism by combining with abamectin. Interesting, ergosterol peroxide (13) distributed widely in mushrooms and fungi, was found to have feeding attractant activities on insects and antifungal activity against entomopathogen Beauveria bassiana. The reciprocal relationship should be occurred between S. commune and pests for the fungus produced ergosterol peroxide to attract the pests propagating spore, and its anti-entomopathogen activity was also benefit for the health of insects.

Abstract
A desymmetrization-based approach for the synthesis of piperidinyl acetic acid γ-secretase modulators has been developed. The synthetic sequence features the use of N-tert-butanesulfinyl imine reduction and a diastereoselective lactam formation to set up the chiral centers. The synthetic utility is demonstrated by the concise asymmetric synthesis of γ-secretase modulator GSM-1.

Abstract
All-enzyme hydrogels are efficient reagents for continuous flow biocatalysis. These materials can be obtained by self-assembly of two oligomeric enzymes, modified with the complementary SpyTag and SpyCatcher units. To facilitate access to the large proportion of biocatalytically relevant monomeric enzymes, we demonstrate that the tagging valency of the monomeric (S)-stereoselective ketoreductase Gre2p from Saccharomyces cerevisiae can be designed to assemble stable, active hydrogels with the cofactor-regenerating glucose 1-dehydrogenase GDH from Bacillus subtilis. Mounted in microfluidic reactors, these gels revealed high conversion rates and stereoselectivity in the reduction of prochiral methylketones under continuous flow for more than 8 days. The sequential use as well as parallelization by 'numbering up' of the flow reactor modules demonstrate that this approach is suitable for syntheses on the semipreparative scale.

Abstract
Continuous flow biocatalysis is an emerging field of industrial biotechnology that uses enzymes immobilized in flow channels for the production of value-added chemicals. We describe the construction of self-assembling all-enzyme hydrogels that are comprised of two tetrameric enzymes. The stereoselective dehydrogenase LbADH and the cofactor-regenerating glucose 1-dehydrogenase GDH were genetically fused with a SpyTag or SpyCatcher domain, respectively, to generate two complementary homo-tetrameric building blocks that polymerize under physiological conditions into porous hydrogels. Mounted in microfluidic reactors, the gels show excellent stereoselectivity with near quantitative conversion in the reduction of prochiral ketones along with high robustness under process and storage conditions. The gels function as compartment that retains intermediates thus enabling high total turnover numbers of the expensive cofactor NADP(H).
