Trying to develop potent and selective anticancer agents, two series of novel 1,2,4-triazolo[3,4-a] phthalazine derivatives were designed and synthesized. Their antitumor activities were evaluated by MU method against four selected human cancer cell lines (MGC-803, EC-9706, HeLa and MCF-7). Our results showed that compound 11h exhibited good anticancer activities compared to 5-fluorouracil against the four tested cell lines, with IC50 values ranging from 2.0 to 4.5 mu M. Flow cytometry analysis indicated that compound 11h induced the cellular early apoptosis and cell cycle arrest at G2/M phase in EC-9706. (C) 2014 Published by Elsevier Masson SAS.

In a document, author is Rego, Yuri F., introduce the new discover, HPLC of Formula: https://www.ambeed.com/products/83-53-4.html.

Fourteen phthalazine-triones bearing different substituents at C-4 position were synthesized through multicomponent reactions (MCR) by using phthalhydrazide, dimedone and diferent aldehydes as starting materials, p-sulfonic acid calix[4]arene as catalyst and ethyl lactate as solvent under microwave irradiation. Compounds 7-16 were obtained in excellent to moderate yields (94-51%) in only 10 min of reaction using this methodology. The antiproliferative activity against cancer cells was disclosed, for the first time, for synthesized compounds. The capacity of all compounds to inhibit cancer cells growth was dependent on the histological origin of cells. Compound 20 was active against more than one strain. (C) 2016 The Authors.

The chemistry of phthalazine derivatives has been of increasing interest since many of these compounds have found many chemotherapeutic applications. So this study aims to synthesize a library of phthalazine derivatives and to investigate their anti-inflammatory and anti-proliferative activities. Sixteen new phthalazinone derivatives (2a-p) were synthesized and tested for their in vitro antiproliferative and in vivo anti-inflammatory activities. All the synthesized compounds were identified and characterized by IR, H-1 NMR, C-13 NMR spectroscopy, and MS. Two compounds, 2b and 2i, showed significant anti-inflammatory activity comparable with that of the standard drug etoricoxib in the carrageenan-induced rat paw edema model at 3 and 5h, respectively. Three compounds (2h, 2j, and 2g) showed moderate sensitivity toward the renal cancer cell line UO-31.

93-28-7, Name is Eugenol Acetate, molecular formula is C12H14O3, belongs to phthalazine compound, is a common compound. In a patnet, author is Dmitrienko, Anton, once mentioned the new application about 93-28-7, Quality Control of Eugenol Acetate.

The aluminum(I) compound NacNacAl (NacNac=[ArNC(Me)CHC(Me)NAr](-), Ar=2,6-iPr(2)C(6)H(3),1) shows diverse and substrate-controlled reactivity in reactions with N-heterocycles. 4-Dimethylaminopyridine (DMAP), a basic substrate in which the 4-position is blocked, induces rearrangement of NacNacAl by shifting a hydrogen atom from the methyl group of the NacNac backbone to the aluminum center. In contrast, C-H activation of the methyl group of 4-picoline takes place to produce a species with a reactive terminal methylene. Reaction of1with 3,5-lutidine results in the first example of an uncatalyzed, room-temperature cleavage of an sp(2)C-H bond (in the 4-position) by an Al(I)species. Another reactivity mode was observed for quinoline, which undergoes 2,2 ‘-coupling. Finally, the reaction of1with phthalazine produces the product of N-N bond cleavage.
