L-Azetidine-2-carboxylic acid (AZC), an analogue of proline, has been shown to partially ameliorate hepatic cirrhosis induced in rats by CCl(4). AZC caused a diminution in formation of collagen in the liver accompanied by a relative decrease in the pool of free proline. The synthesis of
This study was designed to search for a way to inhibit pancreatic fibrosis following acute pancreatitis. Experimental necrotizing pancreatitis was induced by a freezing procedure in the pancreas of male Wistar rats. After the freezing procedure, the rats were divided into 3 groups: nothing addition
Proline analogs inhibit collagen biosynthesis and prevent accumulation of collagen in tissues. The antifibrotic effects of three proline analogs, cis-hydroxyproline, L-azetidine-2-carboxylic acid, and L-3,4-dehydroproline, were compared in a rat oxygen toxicity model. The specificity of these agents
Collagen synthesis was found to be increased in liver slices of rats made cirrhotic by chronic administration of CCl4. The liver function was impaired, as determined by an increased retention of conjugated bilirubin and low serum albumin values. However, when animals received colchicine
Collagen synthesis was measured in liver slices obtained from mice with hepatosplenic schistosomiasis. Enlarged fibrotic livers from these mice contained 20 times more collagen than normal. This model of hepatic fibrosis results from an inflammatory granulomatous host response to Schistosoma mansoni
Excessive accumulation of collagen is a major pathological feature in diseases characterized by tissue fibrosis. Although several therapeutic approaches have been attempted in such patients, currently no treatment modality would specifically reduce collagen deposition in tissues. In this paper we
Several structural analogues of proline have been shown to be incorporated into proteins in place of proline. As a consequence, the proliferation of cells in culture and the extracellular deposition of collagen in animal systems are reduced. In this study, the effects of two proline analogues,
