Synthesis and biological evaluation of orally active matrix metalloproteinase inhibitors
摘要:
The synthesis and biological evaluation of orally active inhibitors of matrix metalloproteinase are reported. Modifications of the P2' position and the a-substituent of hydroxamic acid derivatives were carried out, and revealed that the P2' substituent influenced the MMP inhibitory activities in vitro and in plasma after oral administration. The hydroxamates with phenylglycine at the P2' position were absorbed well orally. Compound 15e, which exhibited the longest duration of inhibitory activity in plasma after oral administration among the phenylglycine derivatives (5a-5d, 15a, 15c, 15e), was evaluated in a rat adjuvant arthritis model. A reduction in hind foot pad swelling and improvements of some inflammatory parameters were demonstrated when the compound was administered orally. These results indicate the potential of MMP inhibitors for rheumatoid arthritis. (C) 1997 Elsevier Science Ltd.

In this report we describe in full the totalsynthesis of the amaryllidaceae alkaloid (+)-plicamine 1 including a model compound study. In both cases the compounds were prepared usingsolid-supportedreagents and scavengers in multi-step sequences of reactions to give materials which required no conventional purification but could be carried on to the next synthetic step.
