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.

[Leu144,Arg147]-PLP (139-151) is a mutant peptide fragment of myelin proteolipid protein (PLP), with the tryptophan and histidine at positions 144 and 147 respectively replaced by leucine and arginine. [Leu144,Arg147]-PLP (139-151) also serves as a T cell receptor (TCR) antagonist for encephalitogenic Th1 clones, blocking their activation in vitro. Furthermore, [Leu144,Arg147]-PLP (139-151) can inhibit the development of experimental autoimmune encephalomyelitis (EAE).

Miriplatin hydrate (SM-11355 (hydrate)) (MPT) is a novel platinum complex used in TACE that shows promise for the treatment of hepatocellular carcinoma (HCC).
