A new series of 6-allylthio-3-aralkylthio-4,5-dimethylpyridazines 5a-5k and 1-allylthio-4-alkylthio5,6,7,8-tetrahydrophthalazine 6a-6j was synthesized from maleic anhydride derivatives for development of new anticancer agents. The process involves the formation of pyridazine and phthalazine rings, dichlorination, allylthiolation, and aralkylthiolation. These new compounds showed antiproliferative activities against breast cancer (MCF-7) and hepatocarcinoma (Hep3B) cells in CCK-8 assays, and could be promising candidates for chemotherapy of carcinomas. Among 21 synthesized compounds, five compounds (5a, 5b, 6b, 6d, and 6f) showed higher potency than 5-FU for inhibiting the growth of cell line. The results indicated that compound 6f had the highest activity towards MCF-7 and Hep3B cells. These results suggest the potential anticancer activity of compounds 5a, 5b, 6b, 6d, and 6f.

In a article, author is Awadallah, Fadi M., introduce new discover of the category.

New phthalazine-based vasodilators were synthesized through the chloroacylation of the starting compound 1-hydrazinophthalazine 4 to give the two key intermediates 5 and 7. These intermediates were used to alkylate various cyclic amines to furnish the final compounds 6a-h and 8a-h. Compounds were tested for their vasorelaxant activities against nor-adrenaline-induced spasm on thoracic rat aorta rings and compared to the reference drug, prazosin. Seven compounds showed higher activity than prazosin, especially compound 8d having an IC50 = 0.10 mM. Molecular modeling studies, including fitting of the synthesized compounds to a 3D-pharmacophore and their docking into optimized homology model as alpha(1)-AR antagonists showed high docking score and fit values. Most vasodilation activities of tested compounds are consistent with their molecular modeling results. (C) 2012 Elsevier Masson SAS. All rights reserved.

In a document, author is Sen, Supriti, introduce the new discover.

A systematic study of the reaction of 1,4-dihydrazinophthalazine (DHPH) with 1,3-dicarbonyls [viz., acetylacetone (acac), dibenzoylmethane (bzbz), and 1-benzoylacetone (bzac)] varying the reaction conditions was carried out to obtain the phthalazine derivatives (1-4). One-pot reaction of DHPH with acac led to the formation of two compounds 1 and 2, with various factors such as the presence of the acid or base, amount of the acac, time of reflux, and the temperature. The reaction conditions of DHPH with bzbz or bzac are sort of different to isolate the products 3 and 4, respectively. The derivatives (1-4) have been characterized by elemental analyses, H-1 NMR, and electrospray ionization-mass spectrometry (ESIMS) and the cytotoxic activity of the compounds 1-4 was evaluated on HeLa cell line.

In a document, author is Abida, introduce the new discover.

Purpose: To prepare some pyridazine derivatives as antioxidant and antimicrobial agents. Methods: The coupling of aryl diazonium salts with diethyl 2-cyano-3-methylglutaconate afforded pyridazine-5-carbonitrile derivatives (3a-e). The methyl function in the pyridazine derivatives (3a-e) reacted with cinnamonitriles to yield phthalazine derivatives (6a-h). Imino-pyridazine derivatives (9a-h) were obtained by reacting 2-aminoprop-1-ene-1,1,3-tricarbonitrile along with aryl diazonium salts (1a-h). Structure elucidation was done by spectral analysis. The 1,1-diphenyl-2-picryl hydrazyl (DPPH) technique was employed to assess antioxidant effect, while evaluation of antimicrobial activity was carried out by serial dilution technique. Results: Compounds, 6f (IC50 = 12.68 mu g/mL; p < 0.05), 6a (IC50 = 14.23 mu g/mL; p < 0.05), and 3c (IC50 = 14.34 mu g/mL; p < 0.05) displayed good antioxidant activity compared to ascorbic acid (IC50 = 12.45 mu g/mL; p < 0.05). Based on the zone of inhibition, compound 6c (p < 0.05) displayed higher activity than ofloxacin (p < 0.05) against E. coli. Conclusion: The presence of an oxo group and carboxylate group plays an important role in the antioxidant activity of these compounds. Compounds 6a, 6f, and 3c can potentially serve as lead compounds for the development of promising antioxidants. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 108-36-1.

Development of poly(ADP-ribose) polymerase inhibitors (PARPi’s) continues to be an attractive area of research due to synthetic lethality in DNA repair deficient cancers; however, PARPi’s also have potential as therapeutics to prevent harmful inflammation. We investigated the pharmacological impact of incorporating spirodiamine motifs into the phthalazine architecture of FDA approved PARPi olaparib. Synthesized analogues were screened for PARP-1 affinity, enzyme specificity, catalytic inhibition, DNA damage, and cytotoxicity. This work led to the identification of 10e (12.6 +/- 1.1 nM), which did not induce DNA damage at similar drug concentrations as olaparib. Interestingly, several worst in class compounds with low PARP-1 affinity, including 15b (4397 +/- 1.1 nM), induced DNA damage at micromolar concentrations, which can explain the cytotoxicity observed in vitro. This work provides further evidence that high affinity PARPi’s can be developed without DNA damaging properties offering potential new drugs for treating inflammatory related diseases.
