The first synthesis of serofendic acids A and B, novel neuroprotective substances isolated from fetal calf serum, is described. This efficient process, starting from (−)-isosteviol, not only provided substantial amounts of serofendic acids, but also established their absolute configuration.
We present efficient syntheses of serofendic acids A and B (SA-A and SA-B), novel neuroprotective substances isolated from fetal calf serum. Biological and pharmacological evaluation showed that SA-A and SA-B have potent protective action aaainst glutarnate-induced neurotoxicity, but do not interact directly with glutamate receptors. A pharmacokinetic study showed that they have good oral bioavailability in rats. The results indicate that SA-A and SA-B are potential lead compounds for candidate drugs to treat various neuroloaical disorders. (C) 2007 Elsevier Ltd. All rights reserved.
Synthesis and neuroprotective effects of serofendic acid analogues
Analogues of serofendic acid were prepared and their protective effects against L-glutamate (Glu)-induced neurotoxicity were examined using primary cultures of rat cortical neurons. Some analogues exhibited similar neuroprotective activity to that of serofendic acid.
