Hoiamides

Posted by naturalproductman on August 6, 2010

William Gerwick and co-workers have published on their studies of hoiamides, which may be a target for voltage gate sodium channels (VGSC).  This channel is a target for the treatment of neurodegenerative disorders – there are neurotoxin sites (at least seven) on VGSCs that are targeted by drugs.
