Mangiferin, a bioactive compound derived primarily from Anacardiaceae and Gentianaceae families and found in mangoes and honeybush tea, has been extensively studied for its therapeutic properties. Mangiferin has shown promising chemotherapeutic and chemopreventative potential. In traditional medicine, different cultures have cultivated and processed mangiferin rich plants for the treatment of a range of illnesses including cardiovascular disease, diabetes, infection and cancer. Mangiferin is primarily implicated in down-regulating inflammation, causing cell cycle arrest, reducing proliferation/metastasis, promoting apoptosis in malignant cells and protecting against oxidative stress and DNA damage. Mangiferin also enhances the capacity of the monocyte-macrophage system and possesses antibacterial activity against gram-positive and gram-negative bacteria.

Maropitant (trade name Cerenia in the U.S. and other countries), used as maropitant citrate is a neurokinin (NK1) receptor antagonist, which was developed by Zoetis specifically for the treatment of motion sickness and vomiting in dogs. It was approved by the FDA in 2007 for use in dogs, and was later approved for use in cats. Maropitant also has anti-nociceptive (analgesic) properties. Maropitant inhibits binding of substance P to NK-1 receptors. Substance P is an emetogen experimentally, and is found endogenously, along with NK-1 receptors, in the emetic center, chemoreceptor trigger zone, and in vagal afferent nerves in the gastrointestinal tract.
