Bioassay-Guided Isolation of an Abetiane-Type Diterpenoid from Prunella vulgaris That Protects against Concanavalin A‑Induced Autoimmune Hepatitis

, 2021
Prunella vulgaris is a widely used edible Chinese medicinal plant. In the present study, two new abietane-type diterpenoids, abietoquinones A (1) and B (2), were isolated from this plant by an immunosuppressive bioassay-guided isolation procedure.

A Cell-Based Potency Assay for Determining the Relative Potency of Botulinum Neurotoxin A Preparations Using Manual and Semi-Automated Procedures

Toxins
Cell-based potency assays (CBPAs) are required for the potency testing and commercial release of botulinum neurotoxin (BoNT)-based drug products. These CBPAs must account for the toxin’s biological activities while meeting regulatory guidelines for ...

Differential sensitivity of locally naturalized Panicum species to 4-hydroxyphenyl pyruvate dioxygenase and acetolactate synthase-inhibiting herbicides

Julius-Kühn-Archiv, 2014
One of the possible reasons for the expansion of the alien panicoid grasses Panicum schinzii (Transvaal millet), Panicum dichotomiflorum (Fall panicum) and Panicum capillare (Witchgrass) in maize fields in Belgium might be a lower sensitivity to post ...
