Formaldehyde has long been used in the chemical inactivation of viral material during vaccine production. Viral inactivation is required so that the vaccine does not infect the patient. Formaldehyde is diluted during the vaccine manufacturing process, but residual quantities of formaldehyde are still present in some current vaccines. Although formaldehyde is considered safe for use in vaccines by the Food and Drug Administration, excessive exposure to this chemical may lead to cancer or other health-related issues. An assay was developed that is capable of detecting levels of residual formaldehyde in influenza vaccine samples. The assay employs incubation of dosage formulation suspensions with hydralazine hydrochloride under mildly acidic conditions and elevated temperatures, where formaldehyde is derivatized to yield fluorescent s-triazolo-[3,4-a]-phthalazine. The assay has been traditionally run by high-performance liquid chromatography, where runtimes of 15 minutes per sample can be expected. Our laboratory has developed a plate-based version that drastically improved the throughput to a runtime of 96 samples per minute. The assay was characterized and validated with respect to reaction temperature, evaporation, stability, and selectivity to monitor residual formaldehyde in various influenza vaccine samples, including in-process samples. Heat transfer and evaporation will be especially considered in this work. Since the assay is plate based, it is automation friendly. The new assay format has attained detection limits of 0.01 mu g/mL residual formaldehyde, which is easily able to detect and quantify formaldehyde at levels used in many current vaccine formulations (<5 mu g/0.5-mL dose).

A ruthenium complex containing a 1,9,10-anthyridine derivative, [Ru(L)(bpy)(2)](PF6)(2) ( [1] (PF6)(2); L = 1,13,14-triazadibenz[a,j]anthracene, bpy = 2,2′-bipyridyl), was synthesized. X-ray crystal structural analysis of [1](PF6)2 showed that L is coordinated to the Ru center as a bidentate ligand. When [1](PF6)(2) was dissolved in acetonitrile, a new complex incorporating one acetonitrile molecule, [Ru(L)(CH3CN)(bpy)(2)](PF6)(2) ([2] (PF6)(2)), was formed. X-ray crystallographic data revealed that, in [2](PF6)(2), L is coordinated to the Ru center in a monodentate fashion. The coordinated L in [2](PF6)(2) shows a unique haptotropic rearrangement in an acetonitrile solution.

Novel urea-functionalized silica-coated magnetic core-shell Fe3-x Ti (x) O-4 nanoparticles were prepared and fully characterized by different methods such as Fourier transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, field emission scanning electron microscopy, high-resolution transmission electron microscopy, vibrating sample magnetometer, X-ray diffraction, and thermogravimetric analyses. These magnetic nanoparticles have been explored as highly efficient and recoverable heterogeneous nanocatalyst for one-pot three-component reactions under mild conditions for the synthesis of diverse range of 5-oxo-dihydropyrano[3,2-c]chromenes known as coumarins and 1H-pyrazolo[1,2-b] phthalazine-5,10-diones in high yields. Simple isolation of the products, use of green solvent, and magnetically easy isolation and reusability of the catalyst with no significant loss of activity are the main advantages of the present method.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 108-36-1. Name: 1,3-Dibromobenzene.

In order to find more efficient and economical antitumor drugs, a series of 1-phenyl-4-substituted phthalazine derivatives were synthesized and evaluated for antiproliferative activity in vivo. The structures of the synthesized compounds were confirmed by H-1 NMR, C-13 NMR and HRMS. The antitumor activity of the target compounds was performed against four cancer cell lines by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT). The results showed that some compounds had a good antitumor activity, especially, N-(4-methoxyphenyl)-2-((4-phenylphthalazin-1-yl)thio)acetamide (5f) and N-(3-chloro-4-fluorophenyl)-2-(4-(4-phenylphthalazin-1-yl)piperazin-1-yl)acetamide (8c), exhibited better antitumor activities with IC50 values of 8.13 and 9.31 mu mol.L-1 against the human esophageal cancer cells, which were superior to 5-fuorouracil.

Purpose: To prepare some pyridazine derivatives as antioxidant and antimicrobial agents. Methods: The coupling of aryl diazonium salts with diethyl 2-cyano-3-methylglutaconate afforded pyridazine-5-carbonitrile derivatives (3a-e). The methyl function in the pyridazine derivatives (3a-e) reacted with cinnamonitriles to yield phthalazine derivatives (6a-h). Imino-pyridazine derivatives (9a-h) were obtained by reacting 2-aminoprop-1-ene-1,1,3-tricarbonitrile along with aryl diazonium salts (1a-h). Structure elucidation was done by spectral analysis. The 1,1-diphenyl-2-picryl hydrazyl (DPPH) technique was employed to assess antioxidant effect, while evaluation of antimicrobial activity was carried out by serial dilution technique. Results: Compounds, 6f (IC50 = 12.68 mu g/mL; p < 0.05), 6a (IC50 = 14.23 mu g/mL; p < 0.05), and 3c (IC50 = 14.34 mu g/mL; p < 0.05) displayed good antioxidant activity compared to ascorbic acid (IC50 = 12.45 mu g/mL; p < 0.05). Based on the zone of inhibition, compound 6c (p < 0.05) displayed higher activity than ofloxacin (p < 0.05) against E. coli. Conclusion: The presence of an oxo group and carboxylate group plays an important role in the antioxidant activity of these compounds. Compounds 6a, 6f, and 3c can potentially serve as lead compounds for the development of promising antioxidants.
