Spectroscopic and Calculated lonization Constants of Some Pyrazines and Pyridazines

The pH dependence of the electronic spectra of some pyrazines and pyridazines was measured in the region between pH 14.3 and H0-10.02.The experimental data were used to investigate the structure of some ionic forms and to calculate the ionization constants.Many constants were also calculated by the CNDO/2 method.The experimental constants show a correlation with the calculated ones.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Synthesis and bioevaluation of 6-chloropyridazin-3-yl hydrazones and 6-chloro-3-substituted-[1,2,4]triazolo[4,3-b]pyridazines as cytotoxic agents

An efficient synthesis of a series of 6-chloro-3-substituted-[1,2,4]triazolo[4,3-b]pyridazines is described via intramolecular oxidative cyclization of various 6-chloropyridazin-3-yl hydrazones with iodobenzene diacetate. The structures of the newly synthesized compounds were assigned on the basis of elemental analysis, IR, NMR (1H and 13C) and mass spectral data. All the thirty three compounds 3a-q and 4b-q synthesized in the present study were evaluated for their in vitro cytotoxic activities against two Acute Lymphoblastic Leukemia (ALL) cell lines named, SB-ALL and NALM-6, and a human breast adenocarcinoma cell lines (MCF-7). The results revealed that triazoles 4 exhibit better cytotoxicity than their hydrazone precursors 3. Among triazoles, compounds 4f, 4j and 4q exhibited potent cytotoxic activity against SB-ALL and NALM-6 with IC50 values in the range of ?1.64?5.66 muM and ?1.14?3.7 muM, respectively, compared with doxorubicin (IC50 = 0.167 muM, SB-ALL). Compounds 4f, 4j and 4q were subjected to apoptosis assay after 48 h treatment and these compounds induced apoptosis of NALM-6 cells via caspase 3/7 activation. Results revealed that compound 4q represents potential promising lead.

Synthesis of imidazo[1,2-b]pyridazine comprised piperazine, morpholine derivatives as potent antimycobacterial agents with in vivo locomotor activity

Background: Heterocyclic compounds have attracted much attention to synthetic and medicinal chemists because of their biological activities especially for tuberculosis (TB). Moreover, fatal forms of TB (including tuberculous meningitis) have led to search for new structural anti-TB agents. So, we have built a scaffold using imidazo[1,2-b]pyridazine, piperazine and morpholine moieties, which are widely used in the inhibition of resistant strains of various organisms. Objective: The aim was to synthesise 6-morpholino-3-(piperazine-1-yl)imidazo[1,2-b]pyridazine containing amide and sulphonamide derivatives and evaluate their antimycobacterial and locomotor activities. Methods: The novel imidazo[1,2-b]pyridazine, piperazine and morpholine scaffolds have been synthesized in seven steps. All the synthesized compounds (8a-j) were screened for in vitro antimycobacterial activity against M.tb H37Rv strains using the MABA, in vivo locomotor activity by using photoactometer and rotarod apparatus. Results: All the synthesized imidazo[1,2-b]pyridazine analogues were characterized by1H NMR,13C NMR and ESI-MS. The compounds 8h and 8j exhibited potent in vitro anti-TB activity at 1.6 mug/mL concentration. Based on the structural and in vitro studies, we had related SAR of 8a-j. Overall, the amide derivatives showed better antitubercular activity than sulphonamide derivatives, which might be due to easy hydrogen bond formation. Moreover, all the derivatives showed significant CNS depressant action lacking neurotoxicity that indicates that the compounds 8a-j have strong lipophilic nature. Conclusion: The presence of novel structure, lipophilicity and non-toxic nature provide impetus for compounds 8a-j in the diagnosis of TB and tuberculous meningitis along with first line anti-TB drugs.

Complementary oxidative generation of iminyl radicals from alpha-imino-oxy acids: Silver-catalyzed c-h cyanoalkylation of heterocycles and quinones

A complementary and general strategy for the oxidative generation of iminyl radicals from the readily available alpha-imino-oxy acids has been established through silver-catalyzed decarboxylation. To demonstrate its synthesis utility, the direct C-H cyanoalkylation of heterocycles and quinones with cyclic alpha-imino-oxy acids via the iminyl radical-mediated C-C bond cleavage is developed. This cost-effective method takes place under mild reaction conditions and exhibits a broad substrate scope.

HIGH PRESSURE SYNTHESIS OF NEW Ag+ ION-SPECIFIC CROWN ETHERS

A variety of double-armed diaza-crown ethers were first prepared through high pressure SNAr reaction, in which unique aromatic heterocycles were successfully attached as secondary binding sites.Direct introduction of aromatic heterocycles such as pyridazine, oxazole, and thiazole rings upon nitrogen atom of the diaza-18-crown-6 provided remarkably high binding and transport selectivity for Ag+ ion.

Towards dual inhibitors of the MET kinase and WNT signaling pathway; Design, synthesis and biological evaluation

Both the kinase MET and the WNT signaling pathway are attractive targets in cancer therapy, and synergistic effects have previously been observed in animal models upon simultaneous inhibition. A strategy towards a designed multiple ligand of MET and WNT signaling is pursued based on the two hetero biaryl systems present in both the MET inhibitor tepotinib and WNT signaling inhibitor TC-E 5001. Initial screening was conducted to find the most suitable ring systems for further optimization, whereas a second screen explored modifications towards pyridazinones and triazolo pyridazines. Up to 54% reduction of WNT signaling activity at 10 muM concentration was achieved, however, only low affinities towards MET were observed. Overall, the thiophene substituted pyridazinone 40 was the best dual MET and WNT signaling inhibitor, with a 17% and 19% reduction of activity, respectively. Although further optimizations are needed to achieve more potent dual inhibitors, the strategy presented herein can be valuable towards the development of a dual inhibitor of MET and WNT signaling.

Palladium-catalyzed heteroaryl thioethers synthesis overcoming palladium dithiolate resting states inertness: Practical road to sulfones and NH-sulfoximines

We provide efficient synthetic access to heteroaryl sulfones in two-steps using a simple palladium?1,1?-bis[(diphenyl)phosphanyl]ferrocene catalyst to form in high yields variously functionalized heteroaromatic thioethers. Pyridinyl-containing substrates can be subsequently selectively oxidized into sulfones and NH-sulfoximines by using very mild oxidation conditions with a high functional group tolerance. In the palladium-catalyzed C?S coupling of heteroaromatic thiols, reactivity limitation is attached with electron-deficient thiols. We show that this limitation can be resolved by the successful use of 2-bromoheteroarenes in the C?S coupling. We established herein that this choice of heteroaryl electrophilic reagent in palladium-catalyzed C?S bond formation allows overcoming palladium dithiolate out-of-cycle resting state inertness. This was illustrated in the stoichiometric reactivity study of the palladium dithiolate formed from 4-trifluoromethylbenzen-1-thiol ?isolated and characterized by multinuclear NMR and XRD? with both 2-chloropyridine and 2-bromopyridine.
