Background: Tendon grafting is mostly required to repair an injury to flexor tendon and due to the importance of this tendon; it needs methods to speed up the re-vitality of the tendon allograft. OBJECTIVES: The aim was to investigate the efficacy of the mesenchymal cells and platelet rich plasma on the hydroxyproline content of frozen allograft tendons after grafting in lamb. METHODS: In this ...
Hydroxylation of proline residues in the Yaa position of the Gly-Xaa-Yaa repeated sequence to 4(R)-hydroxyproline is essential for the formation of the collagen triple helix. A small number of 3(S)-hydroxyproline residues are present in most collagens in the Xaa position. Neither the structural nor a biological role is known for 3(S)-hydroxyproline. To characterize the structural role of 3(S)-h...
The optimized coupling of N-protected (S)-proline and (2S,4R)-4-hydroxyproline derivatives with (Z)-4-aminopent-3-en-2-one provided the expected β-ketoenamides in good to excellent yields. subsequent intramolecular cyclizations afforded enantiopure pyridin-4-one pyrrolidin-2-yl substituents. nonaflates generated from these intermediates were precursors for typical palladium-catalyzed reactions....
