Plant-Environment Interactions, Volume 7, Issue 1, February 2026.ABSTRACT This study investigates the foliar secondary metabolite profiles of four Mitragyna species naturally occurring in Thailand: M. diversifolia, M. hirsuta, M. rotundifolia, and M. speciosa (kratom). Using untargeted gas chromatography–mass spectrometry (GC–MS), 409 secondary volatile metabolites were annotated across the four species.

Combined bead polymerization and Cinchona organocatalyst immobilization by thiol–ene addition
Beilstein Journal of Organic Chemistry, 2012 In this work, we report an unusually concise immobilization of Cinchona organocatalysts using thiol–ene chemistry, in which catalyst immobilization and bead polymerization is combined in a single step.

Cinchona-Derived Picolinamides: Effective Organocatalysts for Stereoselective Imine Hydrosilylation [PDF]
, 2014 Picolinamide-cinchona organocatalysts for the successful enantioselective reduction of ketomines were developed. For the first time, a new type of chiral Lewis base, a cationic species, is reported to efficiently organocatalyze the addition of ...

Imaging malaria parasites across scales and time
Journal of Microscopy, Volume 301, Issue 2, Page 122-150, February 2026.Abstract The idea that disease is caused at the cellular level is so fundamental to us that we might forget the critical role microscopy played in generating and developing this insight. Visually identifying diseased or infected cells lays the foundation for any effort to curb human pathology.
