WebThe intrinsic clearance (Vmax/KM) of S M-1 formation in cytosol was 4 times that in microsomes. In human liver microsomes, S M-1 is exclusively converted to pentoxifylline, whereas approximately 45% of lisofylline oxidation is accounted for by the formation of pentoxifylline and the balance by aliphatic diols. WebOct 4, 2024 · The administration of S-enantiomer lenalidomide is less effective, because it rapidly converts in vivo to the R/S mixture. 41,42 CTP-221 is a deuterated S-enantiomer of lenalidomide at key positions, which decreases the interconversion of enantiomers in-vivo. This helps to administer the potent S-enantiomer with less exposure to R-enantiomer.
