The invention is related to compounds of formula (I) that can be used as antagonists of the TGFβ family type I receptors, Alk5 and/or Alk4, compositions and methods of use. The compounds of formula (I) can be employed in the prevention and/or treatment of diseases such as fibrosis (e.g., renal fibrosis, pulmonary fibrosis, and hepatic fibrosis), progressive cancers, or other diseases for which reduction of TGFβ family signaling activity is desirable.

CCK-B1 receptor) is not as closely related to the CCK central receptor (termed CCK-B2) as previously hypothesized. The antigastric activity of the most potent compound of the series, i.e. (R)-4-(3,5-dichlorobenzamido)-5-(8-azaspiro[4.5]decan- 8-yl)-5-oxopentanoic acid (compound 28, CR 2194) was further evaluated in vivo: in the first hour after administration the compound inhibits acid secretion induced
