AlkaPlorer: A database‐driven explorer for natural alkaloids and derivatives

open access: yesJournal of Integrative Plant Biology, Volume 68, Issue 5, Page 1384-1398, May 2026.
The alkaloid database AlkaPlorer integrates over 130,000 compounds across 12,250 species. By linking chemical structures with biological and evolutionary data, it reveals how these molecules evolve and function. This platform serves as a vital resource for AI‐driven discovery in plant metabolism and modern drug development. ABSTRACT Alkaloids, renowned

Isoquinoline Alkaloids from Corydalis taliensis

open access: yesZeitschrift für Naturforschung B, 2007
Corydalis taliensis Franch is a perennial herb used for treatment of rheumatic arthritis, toothache, and hepatitis. The chemical investigation of this plant resulted in the isolation of a new compound, named taliensineside (1). Its structure was identified on the basis of spectral evidence.

Three Closely Related Spodoptera Species Similarly Affect Gene Expression and Phytohormone Levels but Differentially Induce Volatile Emissions in Maize

open access: yesPlant, Cell &Environment, Volume 49, Issue 5, Page 2394-2412, May 2026.
ABSTRACT Plants can perceive specific elicitors in the oral secretions (OS) of herbivorous insects and respond by increasing their defences. Whether plants can discriminate among similar herbivorous insect species and differentially modulate their defence responses against them is largely unknown.

Recent advances in lamellarin alkaloids: isolation, synthesis and activity [PDF]

open access: yes, 2014
Lamellarins are a large family of marine alkaloids with potential anticancer activity that have been isolated from diverse marine organisms, mainly ascidians and sponges. All lamellarins feature a 3,4-diarylpyrrole system.

Capturing Early‐Stage Chilling Response in Field‐Grown Sorghum and Maize by Integrating Aerial Phenotyping and Metabolomic Signatures

open access: yesPhysiologia Plantarum, Volume 178, Issue 3, May/June 2026.
ABSTRACT Early‐season chilling limits sorghum establishment in temperate environments, yet the metabolic basis of this sensitivity remains poorly understood. We combined temporal spectral reflectance with untargeted metabolomics to characterize species and genotype‐level responses to early planting conditions.

Synthesis of substituted tetrahydroisoquinolines by lithiation then electrophilic quench [PDF]

open access: yes, 2016
Substituted N-tert-butoxycarbonyl (Boc)-1,2,3,4-tetrahydroisoquinolines were prepared and treated with n-butyllithium in THF at −50 °C to test the scope of the metallation and electrophilic quench.

Recent Developments in Sustainable Solubilization

open access: yesChemSusChem, Volume 19, Issue 8, 28 April 2026.
We highlight several recent developments in sustainable solubilization. Particular attention is given to the use of bio‐based solvents derived from renewable resources, the strategic use of water as a solvent, and alternative, sustainable solubilizers such as hydrotropes.

Aporphine Alkaloids from (Annonaceae)

open access: yesNatural Product Communications, 2008
Guatteria species (Annonaceae) are rich in isoquinoline alkaloids that contain a restricted β-phenethylamine moiety and thus have potential as monoamine oxidase (MAO) inhibitors for the treatment of Alzheimer's and Parkinson's diseases.

Label‐Free and Immobilization‐Free Protein‐Binding Assays by Ultraviolet Transient Absorption Microscopy

open access: yesAdvanced Science, Volume 13, Issue 19, 2 April 2026.
A femtosecond UV pump–probe microscope resolves binding‐induced changes in protein excited‐state dynamics and converts these intrinsic contrasts into an equilibrium affinity readout. By probing tryptophan responses directly in solution, the approach enables quantitative determination of dissociation constants without labeling or immobilization ...
