A new series of phthalazine derivatives was synthesized from the reaction of 1-chloro-4-(4-phenoxyphenyl)phthalazine as a reactive starting material with different carbon, nitrogen, oxygen, and sulfur nucleophiles. The structural formulae of all products were confirmed and characterized by elemental analyses and spectral data (IR, H-1 NMR, C-13 NMR, and mass spectra). Some of the synthesized derivatives were screened for their antitumor activity against four human tumor cell lines using MTT assay. In comparison with doxorubicin as standard drug, compounds 1, 20, and 25 showed the most potent cytotoxic effect. In addition, investigation of antioxidant activity revealed that hydrazinylphthalazine 20 has the highest activity.

A new series of phthalazine substituted urea and thiourea derivatives were synthesized, and their inhibitory effects on the activity of purified human carbonic anhydrases (hCAs I and II) were evaluated. 2H-Indazolo[2,1-b]phthalazine-trione derivative (1) was prepared with 4-nitrobenzaldehyde, dimedone, and phthalhydrazide in the presence of TFA in DMF, and nitro group was reduced to amine derivative (2) with SnCl2 center dot 2H(2)O. The compound was reacted with isocyanates and isothiocyanates to get the final products (3a-p). The results showed that all the synthesized compounds inhibited the CA isoenzymes activity. 3a (IC50 = 6.40 mu M for hCA I and 6.13 mu M for hCA II) has the most inhibitory effect. The synthesized compounds are very bulky to be able to bind near the zinc ion, and they much more probably bind as the coumarin derivatives.

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.
