Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:118430-78-7) through the article.
A series of 4-anilinopyrazolopyridine derivatives were synthesized and biol. evaluated as inhibitors of phosphodiesterase (PDE4). Chem. modification of 3, a structurally new chem. lead that was found in our inhouse library, was focused on 1- and 3-substituents. Full details of the discovery of a new orally active chem. lead 5 are presented. Structure-activity relationship data, pharmacol. evaluation, and the subtype selectivity study are also presented.
From this literature《Discovery of new orally active phosphodiesterase (PDE4) inhibitors》,we know some information about this compound(118430-78-7)SDS of cas: 118430-78-7, but this is not all information, there are many literatures related to this compound(118430-78-7).
