A series of 3,8-diazabicyclo[3.2.1]octanes substituted either at the 3 position compounds 1) or at the 8 position (compounds 2) by a chlorinated heteroaryl ring were synthesized, as potential analogues of the potent natural analgesic epibatidine. When tested in the hot plate assay, the majority of the compounds showed significant effects, the most interesting being the 3-(6-chloro-3-pyridazinyl)-3,8-diazabicyclo[3.2.1]octane (la). At a subcutaneous dose of 1 mg/kg, 1a induced a significant increase in the pain threshold, its action lasting for about 45 min. 1a also demonstrated good protection at a dose of 5 mg/kg in the mouse abdominal constriction test, while at 20 mg/kg it completely prevented the constrictions in the animals. Administration of naloxone (1 mg/kg ip) did not antagonize its antinociception while mecamylamine (2 mg/kg ip) did, thus suggesting the involvement of the nicotinic system in its action. Binding studies confirmed high affinity for the alphabeta2 nAChR subtype (K(i) = 4.1±0.21 nM). nAChR functional activity studies on three different cell lines showed that 1a was devoid of any activity at the neuromuscular junction. Finally, due to the analogy in their pharmacological profile with that of epibatidine, compounds were compared from a structural and conformational point of view through theoretical calculations and high-field 1H NMR spectroscopy. Results indicate that all of them present one conformation similar to that of epibatidine.

A series of novel imidazo[1,2-b]pyridazin-3-yl acetamide derivatives (9a-9j) were synthesized from a 3,6-dichloropyridazine. We have developed a simple strategy for the synthesis of functionally diverse imidazole, and pyridiazine derivatives were reported via a series of steps. The work involves bicyclic imidazo-pyridazine ring formation, halogenation, cynation, hydrolysis, peptide coupling, and Buchwald reaction. The structure of the synthesized compounds was confirmed by IR, 1H NMR, 13C NMR,19F NMR, mass spectra, and elemental analysis, and purity is checked by HPLC. All synthesized compounds were screened for anticancer activity against A-549 and Du-145 cancer cell lines by MTT assay. The preliminary bioassay suggests that most of the compounds show anti-proliferation with different degrees; doxorubicin was used as positive control. The synthesized compound shows IC50 values in the range of 1.74muM to 16.17muM in both cell lines. The compounds 9e, 9g, and 9h were active compared with doxorubicin in both the cell lines. The compounds having cyclopentyl ring are active compared with higher and lower carbon analogues.

In the pyridazine series, the use of tert-butylsulfinyl and tert-butylsulfonyl as ortho directing groups for metalation has been tested. Various functionalized products were obtained in good yields. In the case of 3-tert-burylsulfinyl-6-methoxypyridazine, the metalation was regioselective in ortho to the sulfinyl group. The metalation of 2-tert-butylsulfinyl and 2-tert-butylsulfonylpyrazine gave low to moderate yields. Synthesis of diazinesulfonamides were improved and the metalation of N-tert-butylsulfonamidopyrazine was achieved.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Application In Synthesis of 3,6-Dichloropyridazine. Introducing a new discovery about 141-30-0, Name is 3,6-Dichloropyridazine

Six pyridazine-based Schiff base ligands, H2Ln (n = 1-5) and H4L, with N4O2S2 and N4O4S2 donor set atoms, respectively, were prepared by condensation reaction of 3,6-bis-((2-aminoethyl)thio)pyridazine with various salicyladehyde derivatives in ethanol and under solvent-free polyphosphate ester catalyzed conditions. The acid-base properties of H2L2 and H2L3 in DMSO/water (1:1) solution have been studied by spectrophotometric method at 25 C. Optimized geometries of all compounds were also obtained at the B3LYP level of theory. Additionally, the 13C chemical shielding of gas phase H2L1 and H2L2 were studied by the gauge independent atomic orbital (GIAO) and continuous set of gauge transformations (CSGT) methods at the level of density functional theory (DFT). The 6-311++G* basis set was utilized for all of the atoms.

The structure-activity relationships of a series of 4,5-dihydro-6-[4-(1H-imidazol-1-yl)phenyl]-3(2H)-pyridazinones and related compounds were investigated for the in vivo inhibition of different forms of cyclic nucleotide phosphodiesterase (PDE) isolated from guinea pig ventricular muscle. With few exceptions, these 4,5-dihydropyridazinones were potent inhibitors of cardiac type III phosphodiesterase, which is a low K(m), cyclic AMP specific form of the enzyme. The inhibitory effects on cardiac type I and type II phosphodiesterase, both of which hydrolyze cyclic AMP as well as cyclic GMP, were minimal. The most selective PDE III inhibitor was CI-930 (10), the 5-methyl analogue of imazodan (CI-914, 1), with an IC50 of 0.6 muM. The most potent inhibitor of PDE III was the 4,5,6,7-tetrahydrobenzimidazole analogue of 10 (31), with an IC50 of 0.15 muM. This paper describes the structural features that impart both selectivity for inhibiting type III phosphodiesterase and potency of inhibition. In addition, correlations between in vitro PDE inhibitory potency, in vivo positive inotropic potency, and physicochemical properties are discussed.
