Application

AH6809 has been used:
  • as a prostaglandin E2 receptor 1 & 2 (EP1/2) antagonist to analyze its effects on cyclooxygenase-2 /prostaglandin E2 (COX-2/PGE2) signaling in the angiogenic feedback of endothelial cells to hypoxia
  • as an EP2 antagonist to study its effects on tumor angiogenesis in human prostate cancer cell lines
  • as an EP2 antagonist to analyze its effects on overexpression of amyloid precursor protein (APP)

Biochem/physiol Actions

AH6809 plays a role in antagonizing the proliferation of non-small cell lung cancer cell lines.
DP/EP prostanoid receptor antagonist; has the highest affinity for DP receptors, but also acts as a weak antagonist at murine EP1 and EP2 prostanoid receptors.

We investigated the effects of prostaglandin E2 (PGE2) on amyloid precursor protein (APP) expression in cultured rat microglia. PGE2 treatment significantly increased the expression of APP holoprotein and was associated with an elevation in cyclic AMP (cAMP). Direct activation of

In cancer management, the cyclooxygenase (COX)-targeted approach has shown great promise in anticancer therapeutics. However, the use of COX-2 inhibitors has side effects and health hazards; thus, targeting its major metabolite prostaglandin E(2) (PGE(2))-mediated signaling pathway might be a rational

In mammals, sexual differentiation of the hypothalamus occurs during prenatal and early postnatal development due in large part to sex differences in hormones. These early organizational processes are critically important for the attainment and maintenance of adult reproductive functions. We

Urease isoforms from jack bean seeds are toxic to insects, and this entomotoxic effect is mostly due to the release of a peptide by insect digestive enzymes. We previously demonstrated that jack bean urease (JBU) has antidiuretic effects on Rhodnius
