Application

cis-4-Hydroxy-L-proline (CHP) is a proline analog that inhibits collagen synthesis and has been used as an anticancer compound. CHP blocked myotube formation and expression of sarcomeric myosin heavy chain in C2C12 murine skeletal muscle cells. CHP inhibited proliferation of murine Panc02 pancreatic carcinoma cell line and rat pancreatic carcinoma cell line DSL6A.

Biochem/physiol Actions

cis-4-Hydroxy-L-proline (CHP) and its derivatives may have anticancer activity. cis-4-Hydroxy-L-proline and other hydrosyl-L-prolines are important intermediates for chiral synthesis of potential drugs.

Other Notes

Constituent of Amanita sp. peptide toxins but not of animal proteins like collagen.

cis-4-Hydroxy-L-proline (CHP) is being clinically evaluated as an anticancer drug. Since this compound targets the production of L-proline-rich proteins and critical L-proline residues, its impact on long-term cultures of human hepatocytes and toxicity in rats was studied to investigate possible

Hydroxyprolines are valuable chiral building blocks for organic synthesis of pharmaceuticals. Several microorganisms producing L-proline trans-4- and cis-3-hydroxylase were discovered and these enzymes were applied to the industrial production of trans-4- and cis-3-hydroxy-L-proline, respectively. Meanwhile, other hydroxyproline isomers, cis-4- and

Several proline derivatives such as L-azetidine-2-carboxylic acid, cis-4-hydroxy-L-proline, and 3,4-dehydro-DL-proline prevent procollagen from folding into a stable triple-helical conformation, thereby reducing excessive deposition of collagen in fibrotic processes and the growth of tumors. This study was performed to investigate whether
