Gd-based MRI contrast agents (GBCAs) have come under intense regulatory scrutiny due to concerns of Gd retention and delayed toxicity. Three GBCAs comprising acyclic Gd chelates, the class of GBCA most prone to Gd release, are no longer marketed in Europe

We report that 1-benzyl-2-methyl-3-piperidone, conveniently prepared from 3-hydroxy-2-methylpyridine, undergoes rearrangement to 1-benzyl-2-acetylpyrrolidine in aqueous 6 N HCl at reflux. Studies showing that the 2,2-dimethyl analog is inert under the same conditions support a mechanism of reversible tautomeric equilibria via ring-opened intermediates, one of which was independently synthesized and shown to be a kinetically competent intermediate to product.

Page/Page column 63, (2010/11/30)
A class of novel indolizine-1-functional compounds and indolizine-3-functional compounds is disclosed together with the use of such indolizine compounds for inhibiting sPLA2mediated release of fatty acids for treatment of conditions such as septic shock. The compounds are indolizine-1-acetamides, indolizine-1-acetic acid hydrazides, indolizine-1-glyoxylamides, indolizine-3-acetamides, indolizine-3-acetic acid hydraxides, and indolizine-3-glyoxylasides.
