Novel series of phthalazine derivatives 6-11 were designed, synthesized, and evaluated for their anticancer activity against two human tumor cell lines, HCT-116 human colon adenocarcinoma and MCF-7 breast cancer cells, targeting the VEGFR-2 enzyme. Compounds 7a,b and 8b,c showed the highest anticancer activities against both HCT116 human colon adenocarcinoma cells with IC50 of 6.04 +/- 0.30, 13.22 +/- 0.22, 18 +/- 0.20, and 35 +/- 0.45M, respectively, and MCF-7 breast cancer cells with IC50 of 8.8 +/- 0.45, 17.9 +/- 0.50, 25.2 +/- 0.55, and 44.3 +/- 0.49M, respectively, in comparison to sorafenib as reference drug with IC50 of 5.47 +/- 0.3 and 7.26 +/- 0.3M, respectively. Eleven compounds in this series were further evaluated for their inhibitory activity against VEGFR-2, where compounds 7a, 7b, 8c, and 8b also showed the highest VEGFR-2 inhibition with IC50 of 0.11 +/- 0.01, 0.31 +/- 0.03, 0.72 +/- 0.08, and 0.91 +/- 0.08M, respectively, in comparison to sorafenib as reference ligand with IC50 of 0.1 +/- 0.02. Furthermore, molecular docking studies were performed for all synthesized compounds to predict their binding pattern and affinity towards the VEGFR-2 active site, in order to rationalize their anticancer activity in a qualitative way.

Healthcare careers for chemists are once again largely based in laboratories, Name: 4-Nitrobenzoic acid, although increasingly there is opportunity to work at the point of care, helping with patient investigation. 62-23-7, Name is 4-Nitrobenzoic acid, SMILES is O=C(O)C1=CC=C([N+]([O-])=O)C=C1, belongs to phthalazine compound. In a document, author is Sen, Supriti, introduce the new discover.

A systematic study of the reaction of 1,4-dihydrazinophthalazine (DHPH) with 1,3-dicarbonyls [viz., acetylacetone (acac), dibenzoylmethane (bzbz), and 1-benzoylacetone (bzac)] varying the reaction conditions was carried out to obtain the phthalazine derivatives (1-4). One-pot reaction of DHPH with acac led to the formation of two compounds 1 and 2, with various factors such as the presence of the acid or base, amount of the acac, time of reflux, and the temperature. The reaction conditions of DHPH with bzbz or bzac are sort of different to isolate the products 3 and 4, respectively. The derivatives (1-4) have been characterized by elemental analyses, H-1 NMR, and electrospray ionization-mass spectrometry (ESIMS) and the cytotoxic activity of the compounds 1-4 was evaluated on HeLa cell line.

Researchers are common within chemical engineering and are often tasked with creating and developing new chemical techniques, frequently combining other advanced and emerging scientific areas. Product Details of 104-86-9, 104-86-9, Name is (4-Chlorophenyl)methanamine, SMILES is NCC1=CC=C(Cl)C=C1, in an article , author is Jin, Yingzhi, once mentioned of 104-86-9.

Voltage losses in singlet material-based organic photovoltaic devices (OPVs) have been intensively studied, whereas, only a few investigations on triplet material-based OPVs (T-OPVs) are reported. To investigate the voltage loss in T-OPVs, two homoleptic iridium(iii) complexes based on extended pi-conjugated benzo[g]phthalazine ligands, Ir(Ftbpa)(3) and Ir(FOtbpa)(3), are synthesized as sole electron donors. T-OPVs are fabricated by mixing two donors with phenyl-C-71-butyric acid methyl ester (PC71BM) as an electron acceptor. Insertion of oxygen-bridges as flexible inert delta-spacers in Ir(FOtbpa)(3) has slightly elevated both the lowest unoccupied molecular orbital and the highest occupied molecular orbital levels compared to those of Ir(Ftbpa)(3), which results in a lower charge transfer (CT) state energy (E-CT) for Ir(FOtbpa)(3)-based devices. However, a higher V-oc (0.88 V) is observed for Ir(FOtbpa)(3)-based devices than those of Ir(Ftbpa)(3) (0.80 V). To understand the above result, the morphologies of the two blend films are studied, which excludes the influence of morphology. Furthermore, radiative and non-radiative recombination in two devices is quantitatively investigated, which suggests that a higher V-oc can be attributed to reduced radiative and non-radiative recombination loss for the Ir(FOtbpa)(3)-based devices.

In this paper, C-N bond formation between 2,3-dihydrophthalazine-1(4H),4-dione (phthalhydrazide) and alpha,beta-unsaturated esters was investigated and a new series of phthalazine derivatives was synthesized using an efficient and simple method under solvent-free conditions. An aza-Michael addition of phthalhydrazide to both acrylic and fumaric esters led to N-monosubstituted phthalhydrazides (as mono-Michael adduct) in the presence of tetrabutylammonium bromide as a high polar media, and 1,4-diaza-bicyclo[2,2,2] octane as an available organic base. In this reaction, the N1,N2-bis-Michael adduct was not observed at all. Also, reactions were performed at 90 degrees C and yields of products were good to excellent.

In a article, author is Kour, Manmeet, introduce new discover of the category.

A highly active and stable ionic liquid based novel solid Bronsted acid catalyst (C@TiO2-SO3H-ILs) was prepared by coating a long chain ionic liquid onto sulfonated carbon@titania composites. The ionic liquid coating resulted in efficient stability and activity of C@TiO2-SO3H-ILs under aqueous conditions by creating a hydrophobic environment on the catalyst surface. The catalytic activity of the newly designed catalyst was tested in the one-pot multicomponent synthesis of indeno[1,2-b]indole-9,10-diones and 1H-pyrazolo[1,2-b]phthalazine-5,10-diones in aqueous media. The structure of the most active catalyst, C@TiO2-SO3H-IL1, before and after the coating with the ionic liquid was investigated by FTIR, TGA, XRD, CHNS, EDX, SEM and HRTEM. The catalyst allows easy recovery and excellent reusability for up to five catalytic runs without considerable loss of activity.
