In this work, 5,6,7,8-Tetrabromo-2,3-dihydro-2,3-bis(2-hydroxyethyl)phthalazine-1,4-dione is synthesized by the reaction of 5,6,7,8-tetrabromo-2,3-dihydrophthalazine-1,4-dione with 2-bromoethanol in the presence of triethylamine. The obtained monomer was polymerized with different diisocyanates, including hexamethylenediisocyanate (HMDI), tolylene-2,4-diisocyanate (TDI), isophoronediisocyanate ...

N, Nbis(2-chloroethyl)aminobenzoyl picolinoyl hydrazide(BABPH), a benzoic acid nitrogen mustard based new compound and its metal complexes(Cu2+ and Zn2+) have been synthesized and characterized by elemental analysis, IR, 1HNMR, EPR, electronic spectrum, and molar conductivity measurements. In the present study, both BABPH and its complexes exhibited in vitro excellent inhibition of L1210, K562 ...

Complexes [CrO2 (C8H5O4) (H2O) 3] and [CrO2 (C8H5O4) (H2O) 3] .H2O were prepared by reduction of CrO3 at room temperature by ethanol in the presence of phthalic acid (H2pht) yield solution that contains monomeric and dimeric Cr (III) complexes. A solution H2pht/Cr molar ratio of 1:1 and 1:2 is indefinitely stable towards precipitation. Their analysis were done by using elemental (C and H), ICP-...

Here, we have synthesized the hetero-atoms containing; 3, 4, 6–Triazabicyclo [6, 1] dodeca–1 (12), 2, 6, 8, 10–pentene–5–thione (TBD) macrocyclic Schiff base ligand for application in antituberculosis (anti-TB). This TBD moiety has high donor ability due to presence of three nitrogen atoms, which are also reason interaction between and protein molecule. The is characterized by various spectrosc...

Expanders, as lignosulfonates, are crucial for a good performance of Pb/acid batteries. In the process discharge, Pb and PbO2 go to PbSO4. The formed PbSO4 is adsorbed on surface electrode dramatically reduces lifetime battery by formation big crystals. order prevent that, addition expanders in negative an economic solution this investigation, we propose synthesis several lignosulfonates obtain...

BACKGROUND Acute pancreatitis (AP) is a common inflammatory disease of the pancreas accompanied by serious metabolic disturbances. Nevertheless, the specific metabolic process of this disease is still unclear. Characterization of the metabolome may help identify biomarkers for AP. To identify potential biomarkers, this study therefore investigated the 1H-nuclear magnetic resonance (NMR)-based m...

    The solubility enhancement of poorly soluble compounds is an important task in pharmaceutical technology as it leads to better bioavailability and a more efficient application. Fused dispersions (FDs) of simvastatin (SIM) using PEO-PPO block copolymer were prepared which paved the way for the formation of an amorphous product with enhanced dissolution and bioavailability. The accumulative s...

Objective: Synthesis and evaluation of anti-inflammatory activity of some novel 7-azaisatin derivatives. Methods: Novel Schiff bases of 7-azaisatin (VI) were synthesized by condensation of ethyl-2-(1-benzyl-2-oxo-1,2-dihydro-3H-pyrrolo[2,3b]pyridin-3-ylidene) hydrazine carboxylate (V) with various primary amines. The compound (V) was synthesized by reacting ethylchloroformate with 1-benzyl7azai...
