(2R)-1-[6-[(2R)-2-carboxypyrrolidin-1-yl]-6-oxohexanoyl]pyrrolidine-2-carboxylic acid

CPHPC (R-1-[6-[R-2-carboxy-pyrrolidin-1-yl]-6-oxo-hexanoyl] pyrrolidine-2-carboxylic acid) is a proline-derived small molecule able to strip amyloid P (AP) from deposits by reducing levels of circulating serum amyloid P (SAP). The SAP-amyloid association has also been identified as a possible drug target for anti-amyloid therapy, with the recent development and first stage clinical trials of CPHPC for amyloidosis.
