  Synthesis and biological evaluation of α-mannosidase inhibitory activity of three deoxy derivatives of mannostatin A

  摘要：

  Three deoxy derivatives of alpha-mannosidase inhibitor mannostatin A have been synthesized and their inhibitory activity for Jack beans alpha-mannosidase evaluated in order to elucidate roles of each hydroxyl groups of the inhibitor. The 1- and 2-deoxy derivatives have preserved inhibitory potentials although they lowered the activity one-hundred fold compared to the parent, but the 3-deoxy derivative lost activity.

  Synthesis and α-Mannosidase Inhibitory Activity of Three Deoxy Derivatives of Mannostatin A

  摘要：

  Three deoxy derivatives 2-4 of the alpha-mannosidase inhibitor mannostatin A (1) were synthesized, and their inhibition of Jack bean alpha-mannosidase was evaluated in order to elucidate the roles of each of the three hydroxyl groups of the inhibitor. The 1- and 2-deoxy derivatives 2 and 3 retained some inhibitory activity, although reduced by a factor of about 100 relative to the parent, whereas it was completely lost with the 3-deoxy derivative 4. Structure and activity relationships are discussed in the light of these findings.
