At position 1, there is a 2-fluorobenzyl group connected, and the benzyl group is a benzyl group. In this structure, the benzene ring is connected to the pyrazolopyridine structure through methylene (-CH 2O -), and the fluorine atom is connected at position 2 of the benzene ring. The fluorine atom has strong electronegativity, and its introduction will significantly affect the electron cloud density of benzyl group, which in turn will have an effect on the electronic effect and spatial effect of the whole molecule, or change the polarity, lipophilicity and interaction mode with other molecules of the molecule.

At position 3, it is connected to the formamide group (-CONH _ 2). The amide group has unique chemical properties, in which the carbonyl group (C = O) and the amino group (-NH _ 2) are connected through the carbon atom. The presence of the carbonyl group makes the region have a certain polarity, which can participate in intermolecular interactions such as hydrogen bond formation. The amino group can also participate in chemical reactions under appropriate conditions, or form weak interactions with other molecules, affecting the overall properties and functions of the molecule. The introduction of fluorine atoms further alters the electron distribution of the molecule, affecting its acidity, alkalinity, and reactivity with other substances, or enhancing the lipophilicity of the molecule, which has a potential impact on its absorption, distribution, and metabolism in vivo.
