Description

Biochem/physiol Actions

Trans-4-Hydroxy-L-proline is used as a starting material in the synthesis of (-)-secrinine; the synthesis of prolinol-based nucleotide analogues with N-phosphonomethyl moiety attached to the nitrogen atom of prolinol ring and in asymmetric synthesis of the ABC-ring system of the antitumor antibiotic MPC1001.

Trans-4-Hydroxy-L-proline is used in the organic synthesis of depsilairdin analogues, noncompetitive peptidomimetic inhibitors of multidrug resistance P-glycoprotein and 3-guaninyl-5-hydroxymethyl-2-pyrrolidinone (4) or 3-adeninyl-5-hydroxymethyl-2-pyrrolidinone (5) nucleoside analogues.
