Corypalmine (IC50=128.0±10.5 uM) can inhibit prolyl oligopeptidase. (-)-Corypalmine shows inhibition activity against spore germination of some fungi.

Taccalonolide AJ is a microtubule stabilizer; it has excellent and highly persistent antitumor efficacy when administered directly to the tumor, suggesting that the lack of antitumor efficacy seen with systemic administration of AJ is likely due to its short half-life in vivo.

Shield-1 is a specific, high-affinity and cell-permeant ligand of FK506-binding protein-12 (FKBP), and reverses the instability by binding to mutated FKBP (mtFKBP), allowing conditional expression of mtFKBP-fused proteins. Shield-1 can stabilize the entire fusion protein.
