Antagonists

Isosilybin
Catalog No: CFN90260

Isosilybin and Silybin might be suitable candidates to design potent PXR antagonists to prevent drug-drug interactions via CYP3A4 in cancer patients.

Cyclo(Tyr-Pro)
Catalog No: CFN90276

Cyclo(Tyr-Pro) shows antibacterial activity towards several marine bacterial species, it also shows weak antagonistic activity against VEGFR2 -CD. Cyclo(Tyr-Pro) and cyclo(Pro-Val) are toxic to both suspension cells and seedlings of Pinus thunbergii, which may offer some clues to research the mechanism of pine wilt disease caused by pine wood nematode.

Cyclo(Phe-Gly)
Catalog No: CFN90286

Cyclo(Phe-Gly) shows weak antagonistic activity against VEGFR2 -CD, it also shows strong inhibitory activity against human cancer cells(KB,KBv200) with LD50 at 6.5 and 11.2 umol/L,respectively.

Phellopterin
Catalog No: CFN90495

Phellopterin is a partial agonist of the central benzodiazepine receptors in vitro; it shows cytotoxic effect on RAW264.7 cell at the concentration from 40 to 400 μM. Phellopterin reduces TNF-alpha-induced VCAM-1 expression through regulation of the Akt and PKC pathway, which contributes to inhibit the adhesion of monocytes to endothelium.

Voacangine
Catalog No: CFN92252

Voacangine is a novel transient receptor potential vanilloid type 1 (TRPV1) antagonist, it shows mod. cytotoxic activity, also some CNS, brachycardial and hypotensive action.Voacangine significantly suppresses in vitro angiogenesis, such as VEGF-induced tube formation and chemoinvasion.
