Mechanism of multiple lysine methylation by the SET domain enzyme Rubisco LSMT

Discovery, synthesis and preclinical characterization of N-(3-chloro-4-fluorophenyl)-1H-pyrazolo[4,3-b]pyridin-3-amine (VU0418506), a novel positive allosteric modulator of the metabotropic glutamate receptor 4 (mGlu4)

It is also important to consider the fact that the bioavailability of L-carnitine and acylcarnitine derivatives administered orally is low (~10-20%) (see Metabolism and Bioavailability)
