Ponalrestat is the inhibitor of aldehyde reductase 2 from a number of sources. Ponalrestat blunted Prostaglandin F2 alpha synthesis by preadipocytes in basal and stimulated conditions. Ponalrestat suppresses IL-1 production both in vitro and in vivo, and inhibits the cachectic symptoms induced by colon26 adenocarcinoma in mice, suggesting that ponalrestat has a therapeutic potential for the treatment of cancer cachexia. In a 4-week study of 29 neuropathic diabetics treated with ponalrestat peripheral neuropathy did not improve during treatment. In a 6-week study of 21 diabetics without neuropathy, although vagal function improved in patients with autonomic neuropathy.
