Auxinole is a potent auxin antagonist of TIR1/AFB receptors, binding TIR1 to block the formation of the TIR1-IAA-Aux/IAA complex . It inhibits auxin-responsive gene expression.

Activator of protein kinase C; attached to cell permeabilization Antennapedia domain vector peptide. Consists of peptide derived from the C2 domain of PKC β linked by a disulfide bridge to the Antennapedia domain vector peptide. The Antennapedia peptide is actively taken up by intact cells, at 4 or 37°C, ensuring rapid and effective uptake of the activator peptide. Once inside the cell, the disulfide bonds are subjected to reduction in the cytoplasm leading to release of the activator peptide.

Mesosulfuron-methyl is a systemic herbicide. It is used for post-emergence control of grasses and other weeds in cereals.
