Tille, J.-C. published the artcileVascular endothelial growth factor (VEGF) receptor-2 antagonists inhibit VEGF- and basic fibroblast growth factor-induced angiogenesis in vivo and in vitro, Recommanded Product: N-(3-Bromo-4-methylphenyl)-4-(pyridin-4-ylmethyl)phthalazin-1-amine, the publication is Journal of Pharmacology and Experimental Therapeutics (2001), 299(3), 1073-1085, database is CAplus and MEDLINE.

Exponential tumor growth is angiogenesis-dependent. Vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) are potent angiogenic inducers that act synergistically in vivo and in vitro. We assessed the effect of specific inhibitors of VEGF receptor (VEGFR)-2 tyrosine kinase activity in in vivo and in vitro models of VEGF- and bFGF-induced angiogenesis. In an implant mouse model of angiogenesis, VEGFR-2 inhibitors completely blocked angiogenesis induced by VEGF, and, surprisingly, also inhibited the effect of bFGF to various extents. In vitro, VEGF- and bFGF-induced bovine microvascular and aortic endothelial (BME and BAE) cell collagen gel invasion could be blocked by the VEGFR-2 inhibitors by 100 and ∼90%, resp. Similar results were obtained with VEGFR-1-IgG and VEGFR-3-IgG fusion proteins and with VEGFR-2 blocking antibodies. Both BME and BAE cells produce VEGF and VEGF-C, which is not modulated by bFGF. Thus, the unexpected inhibition of bFGF-induced angiogenesis by VEGFR-2 antagonists reveals a requirement for endogenous VEGF and VEGF-C in this process. These findings broaden the spectrum of mediators of angiogenesis that can be inhibited by VEGFR-2 antagonists and highlight the importance of these compounds as agents for inhibiting tumor growth sustained by both VEGF and bFGF.

A rarely explored oxidative ring contraction of electron-rich 1,2-diazine was described. Upon treatment with an electrophilic chlorinating reagent (TCICA), 1,4-dimethoxyphthalazines undergo an N-chlorination-induced ring contraction that was accompanied by the loss of one nitrogen atom. The scope of this unusual reactivity was examined with a range of 1,4-dimethoxyphthalazine derivatives In addition, a mechanism proceeding via a bicyclic species was proposed on the basis of an isolated reaction intermediate and DFT calculations

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder for which no cognition-restoring therapies exist. Gamma-aminobutyric acid (GABA) is the primary inhibitory neurotransmitter in the brain. Increasing evidence suggests a remodeling of the GABAergic system in AD, which might represent an important therapeutic target. An inverse agonist of alpha 5 subunit-containing GABAA receptors (alpha 5GABAARs), 3-(5-Methylisoxazol-3-yl)-6-[(1-methyl-1,2,3-triazol-4-yl)methyloxy]-1,2,4-triazolo[3-a]phthalazine (alpha 5IA) has cognition-enhancing properties. This study aimed to characterize the effects of alpha 5IA on amyloid beta (A beta(1-42))-induced molecular and cellular changes. Mouse primary hippocampal cultures were exposed to either A beta(1-42) alone, or alpha 5IA alone, alpha 5IA with A beta(1-42) or vehicle alone, and changes in cell viability and mRNA expression of several GABAergic signaling components were assessed. Treatment with 100 nM of alpha 5IA reduced A beta(1-42)-induced cell loss by 23.8% (p < 0.0001) after 6 h and by 17.3% after 5 days of treatment (p < 0.0001). Furthermore, we observed an A beta(1-42)-induced increase in ambient GABA levels, as well as upregulated mRNA expression of the GABAAR alpha 2,alpha 5,beta 2/3 subunits and the GABABR R1 and R2 subunits. Such changes in GABARs expression could potentially disrupt inhibitory neurotransmission and normal network activity. Treatment with alpha 5IA restored A beta(1-42)-induced changes in the expression of alpha 5GABAARs. In summary, this compound might hold neuroprotective potential and represent a new therapeutic avenue for AD. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Human hepatocytes are a physiologically relevant tool useful in evaluating liver-related pharmacokinetics, including non-cytochrome P-450 (CYP) metabolism, due to their broad spectrum of metabolic enzyme activity. To verify the usefulness of human hepatocytes in evaluating non-CYP metabolism for drug discovery, we compared intrinsic clearance values (CLint) in freshly isolated and cryopreserved hepatocytes using 14 compounds primarily metabolized by non-CYP enzymes, including UDP-glucuronosyltransferase, carbonyl/aldo-keto reductase, aldehyde oxidase, flavin-containing monooxygenase, and monoamineoxidase. Cryopreservation resulted in a > 20% reduction (maximum: 50%) in CLint in 7/14 compounds (statistically significant for 5 compounds) on comparing CLint values in freshly isolated and cryopreserved hepatocytes from the same donors (n = 4). However, the number of compounds with > 20% CLint reduction decreased to 3 on comparing average of CLint values including un-matched donors (dolasetron: -27%, naltorexone: -32%, and phthalazine: -48%; statistically significant for phthalazine, n = 6-11). These findings suggest that fresh hepatocytes are useful in evaluating intact non-CYP enzyme activities. However, we must note that the reduction in CLint by cryopreservation could be rendered negligible if high-activity lots are selected for assay. We therefore recommend using cryopreserved hepatocytes for large-scale screening for non-CYP metabolism in drug discovery research considering the advantages in usability with cryopreserved hepatocytes.
