In our endeavor towards the development of effective VEGFR-2 inhibitors, three novel series of phthalazine derivatives based on 1-piperazinyl-4-arylphthalazine scaffold were synthesized. All the newly prepared phthalazines 16a-k, 18a-e and 21a-g were evaluated in vitro for their inhibitory activity against VEGFR-2. In particular, compounds 16k and 21d potently inhibited VEGFR-2 at sub-micromolar IC50 values 0.35 +/- 0.03 and 0.40 +/- 0.04 mu M, respectively. Moreover, seventeen selected compounds 16c-e, 16g, 16h, 16j, 16k, 18c-e and 21a-g were evaluated for their in vitro anticancer activity according to US-NCI protocol, where compounds 16k and 21d proved to be the most potent anticancer agents. While, compound 16k exhibited potent broad spectrum anticancer activity with full panel GI(50) (MG-MID) value of 3.62 mu M, compound 21d showed high selectivity toward leukemia and prostate cancer subpanels [subpanel GI(50) (MG-MID) 3.51 and 5.15 mu M, respectively]. Molecular docking of compounds16k and 21d into VEGFR-2 active site was performed to explore their potential binding mode. (C) 2015 Elsevier Masson SAS. All rights reserved.

The fermentation of the endophyte Fusarium oxysporum SS46 and Fusarium oxysporum ATCC MYA 4623 with epigenetic modulator hydralazine in Czapek medium led to the isolation of 3-methyl-1,2,4-triazolo [3,4-alpha] phthalazine (1). The mechanism of biotransformation involves reaction with acetyl-CoA and further cyclization, and was unveiled using C-13-precursor. Additionally, AFLP technique for genomic DNA and differential gene expression (cDNA) analyses were applied for comparative profiling of the fungus under and without treatment with hydralazine. There was no change in the DNA profile of hydralazine-treated and non-treated cultures; however, cDNA-AFLP analyses showed a differential gene expression in the cultures after treatment of the fungi with hydralazine.

Intramolecular electrophilic cyclization of a bisanthranilate afforded an angular cis-quinacridone compound, which condensed with hydrazine to give a phthalazine derivative. A [2+2+2] cyclization reaction occurred at the C-N double bond position of phthalazine when reacted with dimethyl acetylenedicarboxylate. The structures of these novel compounds were confirmed by crystallographic analysis. The phthalazine derivative decomposes back to quinacridone at ambient condition in the dark and as a solid with a half lifetime of about 22 months.

In a patnet, author is El-Gazzar, Marwa G., once mentioned the new application about 90-64-2.

Aims and Objective: A series of novel phthalazine derivatives was synthesized with versatile, readily accessible electrophilic and nucleophilic reagents. The newly synthesized compounds were confirmed by the results of spectroscopic measurements. Hence, their potential clinical application investigated in particular for cancer treatment. Materials and Methods: The newly synthesized compounds were characterized by spectroscopic measurements and were tested for their in vitro anticancer activity by MTT assay against human liver cancer cell line. Docking study of all the synthesized compounds was performed within the active site of the enzyme VEGFR-2 (Vascular Endothelial Growth Factor Receptor-2). Results: The quinazoline derivative 12 emerged as the most potent compound in this study with an IC50 value of 5.4 mu M. Docking study showed that the synthesized compounds were fit in the VEGFR-2 active site almost at the same position of sorafenib and vatalanib with comparable docking scores (-15.20 to -8.92 was kcal/mol). Conclusion: we have synthesized a novel series of phthalazine derivatives and evaluated their potential anticancer activity against HEPG2 cell line. The quinazoline derivative 12 emerged as the most potent compound in this study with an IC50 value of 5.4 mu M. The SAR and docking studies pointed out that rigidification of the structure resulted in better activity and better binding within the active site of VEGFR-2 as in compounds 3, 5, 6 and 12. These results introduced new phthalazine derivatives having promising activity which could lead to the development of more potent anticancer agents.
