The binding affinity depended on the position and size of the substituents. The most interesting compounds were further evaluated in functional studies on isolated organs and in vivo for cholinergic side effects. Compounds 5l and 6i displayed good M<sub>1<\/sub> and M<sub>3<\/sub> antagonistic properties in vitro and were devoid of cholinergic side effects in vivo. In the experiment, the researchers used many compounds, for example, 3-(1H-Pyrazol-3-yl)pyridine (cas: 45887-08-9<a href=\"https:\/\/www.ambeed.com\/products\/45887-08-9.html\">COA of Formula: C8H7N3<\/a>).<\/p>\n<p>3-(1H-Pyrazol-3-yl)pyridine (cas: 45887-08-9) belongs to pyrazole derivatives.

The presence of both electronegative nitrogen atoms in the pyrazole ring reduces the electron density of the C3- and C5-positions leaving electron density of C4-position unaltered. Thus the C4-position is vulnerable to electrophilic attack.
