Application

(R)-(+)-α-Hydroxy-γ-butyrolactone can be used as a starting material to synthesize:
  • δ-Azaproline by reacting with benzyloxycarbonyl aminophthalimide via Mitsunobu reactions.
  • Homochiral (R)-2,4-dihydroxybutyramide seco-pseudonucleoside reagents.
  • Botryolide B via esterification and ring-closing metathesis reaction.
  • Pregnane derivatives containing γ-butyrolactones as potential glucocorticoid agonists.

Dentin sialoprotein (DSP), the NH2-terminal fragment of dentin sialophosphoprotein (DSPP), is essential for dentin formation and further processed into small fragments inside the odontoblasts. Gelatinases, including matrix metalloproteinases 9 (MMP9) and MMP2, were able to cleave DSP(P) in tooth structures.
