Bibapcitide, a 26 amino acid, bis-succinimidomethyl ether-linked dimer of the peptide apcitide is a component of lyophilized kit having the trade name AcuTect. When pertechnetate (99mTcO4-) is added to the AcuTect radiopharmaceutical kit and the resulting kit is heated, [99mTcO] apcitide forms. This kit is used for scintigraphic imaging of veins to identify acute venous thrombosis in the lower legs.

Resiniferatoxin (RTX or RTX-107) is a vanilloid derived from a cactus-like plant (Euphoria resiniferous) and has anti-inflammatory activity. This compound is an agonist of the transient receptor potential vanilloid 1 (TRPV1). Resiniferatoxin produces analgesia by desensitizing the TRPV1 receptor. Findings of several studies have suggested a potential therapeutic use of the anti-inflammatory effect of resiniferatoxin. Phase I and II clinical trials have been completed or are underway, evaluating the safety and efficacy of resiniferatoxin in pain-related disorders such as osteoarthritis and cancers.
