Superactivation of the Botulinum Neurotoxin Serotype A Light Chain Metalloprotease: A New Wrinkle in Botulinum Neurotoxin
摘要:
Small molecules based upon a 2-acylguanidine-5-phenyl thiophene scaffold that can activate the light chain metalloprotease of botulinum neurotoxin serotype A (BoNT LC/A) by an apparent reduction in Km are reported. On the basis of structure-activity relationships and the activation profile, one or more molecules of activator specifically bind to a defined site on the toxin, causing the observed rate enhancement. With the ever-growing clinical uses of BoNT, compounds such as those reported here may provide a method for combating the emerging adaptive immune responses to BoNT.

The palladium-catalyseddirectarylation of methyl 2-furoate with arylbromides was studied. The use of KOAc as the base, dimethylacetamide (DMAc) as the solvent and Pd(OAc)2 as the catalyst was found to give 5-arylfurans regioselectively and without decarboxylation. These methyl 5-aryl-2-furoates gave 2,5-diarylfurans by decarboxylative coupling by using Pd(OAc)2 as the catalyst. Methyl 2-furoate
