Biochem/physiol Actions

B-9430 was developed by Gera at the Stewart laboratory¹ and is a stable, potent, and long lasting Bradykinin (BK) antagonist, a candidate anti-inflammatory drug. B-9430 shows potency at bradykinin B2 (pA₂ = 8.6) and B1 receptors (pA₂ = 7.3). Bradykinin is an important growth factor for small-cell lung cancer (SCLC) and prostate cancer (PC). BK receptors are expressed on almost all lung cancer cell lines and on many PC cells. B-9430 is very resistant to kinases and thus shows a very long action in vivo. This peptide is unique among bradykinin antagonists in that it is active after oral administration.
