Piriprost is a structural analog of prostaglandin I2 (PGI2) with low IP receptor-mediated activity. Piriprost inhibits 5-lipoxygenase with an IC50 around 100 µM, as measured by the release of 5-HETE from cultured myometrial cells.1 Piriprost inhibits the release of histamine and leukotrienes from isolated porcine lung cells with an IC50 of 0.11 µM, implicating its role in inflammation and allergic responses.2

Cayman Chemical was formed over thirty years ago by demonstrating the value of naturally growing gorgonian corals as a renewable, economically viable source of prostaglandins. Today we operate our business knowing that we owe our start to the renewable resources our environment had provided. As Cayman Chemical continues to grow we consistently evaluate our business processes to ensure we are operating at the highest environmental standards.
