  • Description Pyridazine, sometimes called 1,2-diazine, is a six-membered ring containing two adjacent nitrogen atoms. Pyridazine is a privileged structure in medicinal chemistry and can be used as an isosteric replacement of phenyl or heteroaromatic rings. Pyridazines can improve the physiochemical properties of drug molecules by increasing their water solubility, participating as hydrogen bond acceptors, and have a high capacity to complex with targets due to their dipole moment. Pyridazine confers bioavailability, especially to the CNS, and can reduce toxicity. Pyridazine is a part of several drug molecules, and the pyradzine pharmacophore has led to a variety of pharmacologically active compounds.
  • Uses Pyrrolo[1,2-b]pyridazine 1 is a N-bridgehead aromatic heterocycle containing two nitrogen atoms, is obtained by the condensation of pyridazine and pyrrole.
