In a article, author is Bunce, Richard A., introduce new discover of the category.

Four phthalazine derivatives have been prepared from substituted 2-bromobenzaldehyde acetals by a sequence involving: (1) lithiation and formylation; (2) deprotection; and (3) condensative cyclization with hydrazine. Two additional phthalazines were prepared by a similar sequence following direct lithiation of benzaldehyde acetals substituted by anion-stabilizing groups at C3. These syntheses can be conveniently carried out to give phthalazines in overall yields of 40-70%.

In order to find more efficient and low toxicity antitumor drugs, a series of novel 1,3-disubstituted pyridazinone derivatives were synthesized and evaluated for their antiproliferative activities against four human cancer cell lines (MCF-7, PC-3, SW-620 and HGC-27) in vitro. The results showed that most compounds had good antiproliferative activities, especially 2-(4-(4-bromophenyl)-1-oxo-tolylazine-2(1H)-yl)-N-(2-fluorophenyl)acetamide (5g) exhibited better antiproliferative activities with IC50 value of 6.01 mu mol/L.

In a document, author is Han, Lyrialle W., introduce the new discover, Quality Control of 3-Ethyltoluene.

Hydralazine, an antihypertensive agent used during pregnancy, undergoes N-acetylation primarily via N-acetyltransferase 2 (NAT2) to form 3-methyl-1,2,4-triazolo[3,4-a]phthalazine (MTP). To characterize the steady-state pharmacokinetics (PK) of hydralazine during pregnancy and evaluate the effects of NAT2 genotype on hydralazine and MTP PK during pregnancy, 12 pregnant subjects received oral hydralazine (5-25 mg every 6 hours) in mid- (n = 5) and/or late pregnancy (n = 8). Serial blood samples were collected over 1 dosing interval, and steady-state noncompartmental PK parameters were estimated. Subjects were classified as either (rapid acetylators, n = 6) or slow acetylators (SAs, n = 6) based on NAT2 genotype. During pregnancy, when compared with the SA group, the RA group had faster weight-adjusted hydralazine apparent oral clearance (70.0 +/- 13.6 vs 20.1 +/- 6.9 L/h, P .05), lower dose-normalized area under the concentration-time curve (AUC; 1.5 +/- 0.8 vs 5.9 +/- 3.7 ng center dot h/mL, P .05), lower dose-normalized peak concentrations (0.77 +/- 0.51 vs 4.04 +/- 3.18 ng/mL, P .05), and larger weight-adjusted apparent oral volume of distribution (302 +/- 112 vs 116 +/- 45 L/kg, P .05). Furthermore, the MTP/hydralazine AUC ratio was similar to 10-fold higher in the RA group (78 +/- 30 vs 8 +/- 3, P .05) than in the SA group. No gestational age or dose-dependent effects were observed, possibly because of the small sample size. This study describes for the first time, the PK of oral hydralazine and its metabolite, MTP, during pregnancy, and confirmed that the PK of oral hydralazine is NAT2 genotype dependent during pregnancy.
