Now introduce a scientific discovery about this category.

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.

Properties of dimethyl 3-(alkylamino)-5,10-dioxo-5,10-dihydro-1H-pyrazolo[1,2-b]phthalazine-1,2-dicarboxylate and its derivatives were studied by means of ab initio method. NO2 derivative of title compound was synthesized and the nature of its intramolecular hydrogen bond (HB) was investigated. Furthermore, the topological properties of the electron density distributions for N-H…O intramolecular bridges were analyzed in terms of the Bader theory of atoms in molecules (AIM). The electron density (?) and Laplacian (?2?) properties, estimated by AIM calculations, indicated that O…H bond possesses low ? and positive ?2? values which are in agreement with electrostatic character of the HBs, whereas N-H bonds have covalent character (?2?<0). Moreover, steric effect of the t-Bu group on structure and topological parameters of pyrazolo[1,2-b]phthalazine conformers was studied. Finally, the powerful method of Espinosa was used to obtain the H-bond energy. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 102089-74-7, Name is Boc-D-Phenylglycinol, molecular formula is C13H19NO3. In an article, author is Jalili-Baleh, Leili,once mentioned of 102089-74-7, Recommanded Product: 102089-74-7.

A novel series of tacrine-like compounds 7a-u possessing a fused pyrazolo[1,2-b]phthalazine structure were designed and synthesized as potent and selective inhibitors of AChE. The in-vitro biological assessments demonstrated that several compounds had high anti-AChE activity at nano-molar level. The more promising compound 71 with IC50 of 49 nM was 7-fold more potent than tacrine and unlike tacrine, it was highly selective against AChE over BuChE. The cell-based assays against hepatocytes (HepG2) and neuronal cell line (PC12) revealed that 71 had significantly lower hepatotoxicity compared to tacrine, with additional neuroprotective activity against H2O2-induced damage in PC12 cells. This compound could also inhibit AChE-induced and self-induced A beta peptide aggregation. The advantages including synthetic accessibility, high potency and selectivity, low toxicity, adjunctive neuroprotective and A beta aggregation inhibitory activity, make this compound as a new multifunctional lead for Alzheimer’s disease drug discovery.

Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels. 23981-47-7, Name is 2-(6-Methoxynaphthalen-2-yl)acetic acid, molecular formula is C13H12O3. In an article, author is Etinski, Mihajlo,once mentioned of 23981-47-7, Category: phthalazines.

Quinazoline, quinoxaline and phthalazine are nitrogen containing heterocyclic aromatic molecules which belong to the class diazanaphthalenes. These isomers have low-lying n pi(star) and naphthalene-like pi pi(star) states that interact via spin-orbit coupling. In this contribution, we study their structure and electronic states by means of a coupled-cluster method. The computed properties are compared to those of cinnoline which were obtained in our previous study [Etinski et al., Phys. Chem. Chem. Phys., 2014, 16, 4740]. The excited state features of these isomers are dependent on the position of the nitrogen atoms. We find that quinazoline and quinoxaline exhibit similarities in the ordering and character of the excited states. In contrast, a marked difference in the electronic and geometric structures of the lowest excited triplet states of cinnoline and phthalazine is noticed, although both are orthodiazanaphthalenes. Our findings suggest that the S-1 (sic) T-1 channel is responsible for the rapid intersystem crossing in quinazoline and quinoxaline, whereas the S-1 (sic) T-2 pathway is active in phthalazine.
