1H-Imidazo[4,5-c]pyridine-4-carbonitrile as cathepsin S inhibitors: Separation of desired cellular activity from undesired tissue accumulation through optimization of basic nitrogen pka
摘要:
Based on the theoretical understanding of the in vivo lysosomotropism, by adjusting the pk(a) of basic nitrogen containing cathepsin S inhibitors, a set of compounds with pk(a) 6-8 were identified to have excellent cell based Lip10 activity, yet avoiding undesired sequestration in spleen.
