作者: Rong, Jian ; Liang, Steven H.
This patent highlight describes novel substituted 5,6-fused and 6,6-fused bicyclic compounds as 15-prostaglandin dehydrogenase (15-PGDH) modulators.It provides a detailed account of their synthesis, pharmaceutical composition, and potential use in the treatment for 15-PGDH-related diseases, such as intestinal, gastrointestinal, or bowel disorders.
Amgen has entered an agreement to acquire US-based biopharmaceutical company Rodeo Therapeutics for up to $721m.
According to the deal, Amgen will acquire all outstanding shares of Rodeo for an upfront payment of $55m. Rodeo is eligible to receive future contingent milestone payments worth up to an additional $666m in cash.
Amgen Global Research senior vice-president Raymond Deshaies said: “The enzyme 15-PGDH plays a key role in many disease-relevant processes such as stem cell self-renewal and epithelial barrier repair.
“Given the encouraging preclinical data to date, we are excited about the opportunity to develop a novel therapy with potential in a range of important inflammatory disease indications.”
Founded in 2017, Rodeo focuses on developing first-in-class, orally available modulators of prostaglandin biology that perform a major role in tissue regeneration and repair.
Amgen noted that Rodeo’s 15-prostaglandin dehydrogenase (15-PGDH) programme is a robust strategic fit with its inflammation portfolio and its efforts in developing first-in-class treatments for patients.
In extensive preclinical studies, Rodeo’s lead 15-PGDH modulators have produced compelling results and possess clinical potential in different indications.
Rodeo president and CEO Thong Le said: “We are thrilled that Amgen recognises the potential value and differentiated profile of our 15-PGDH inhibitor programme.
“With decades of experience in developing, manufacturing and commercialising innovative therapies for patients suffering from a broad range of immunologic diseases and conditions, Amgen is ideally positioned to rapidly advance our programme into the clinic.”
