Herein, we described the design and synthesis of a series of pyridazine-3-carboxamides to be CB2-selective agonists via a combination of scaffold hopping and bioisosterism strategies. The compounds were subjected to assessment of their potential activities through calcium mobilization assays. Among the tested derivatives, more than half of these compounds exhibited moderate to potent CB2 agonist activity. Six compounds showed EC50 values below 35 nM, and several derivatives also exhibited significantly enhanced potency and high selectivity at the CB2 receptor over the CB1 receptor. Specifically, compound 26 showed the highest CB2 agonist activity (EC50 = 3.665 ± 0.553 nM) and remarkable selectivity (Selectivity Index > 2729) against CB1. In addition, logPs of some representative compounds were measured to display significantly decreased values in comparison with GW842166X. Furthermore, docking simulations were conducted to explain the interaction mode of this series.

The synthesis of new α-helix scaffolds mimicking i, i+3 or i+4, i+7 residues, was accomplished. The common pyridazine heterocycle originates from the easily available building block, 6. These scaffolds may be thought of as synthetic counterparts of amphip

3-Chloropyridazine-6-carboxylic acid hydrazide (5) was synthesized by employing hydrazine monohydrate and methyl levalinate as starting materials through five steps, including hydrazinolysis. Selective hydrazinolysis of 3,6-substituted pyridazines was investigated.
