In a document, author is Iravani, Nasir, introduce the new discover.

A novel heteropolyanion-based Bronsted acidic ionic liquid material [PhBS](3)PW12O40, butane mono-sulfoacid-functionalized phenanthrolinum salt of phosphortungstate catalyst (PhBS-PW), was synthesized and well characterized with FTIR, H-1 and C-13 NMR, electro-spray ionization mass spectrometry (ESI-MS), EDX and TG analysis techniques. The new prepared catalyst was used for the efficient one-pot synthesis of 2H-indazolo[2,1-b]phthalazine-trione derivatives from a three-component condensation reaction between aromatic aldehydes, dimedone, and phthalhydrazide in H2O under thermal conditions. This green approach has several advantages such as short reaction times, clean reaction profiles, and simple experimental and workup procedures. Moreover, the catalyst can be easily recovered and reused at least nine times with only slight reduction in its catalytic activity with no leaching amount of catalyst into the reaction mixture. These economical factors (time, cost, waste, etc.) for this three-component reaction hold promise for the future of organic synthesis.

A novel Keggin-type heteropolyacid-based ionic liquid [Simp](3)PW12O40 was developed via the reaction of the as synthesized ionic liquid 3-sulfonic acid 1-imidazolopyridinium hydrogen sulfate [Simp]HSO4 with an aqueous solution of H3PW12O40. Then, the formulated [Simp](3)PW12O40 was changed to the nano-form via solvothermal processing in tetralin at 220 degrees C. After that, the provided powdered solid nanomaterial was characterized by FTIR, H-1 NMR, XRD, SEM, EDX and TGA analyses. Then, the focused nanomaterial was handled as a productive and encouraging nanocatalyst for the establishment of 2H-indazolo[2,1-b]phthalazine-1,6,11(13H)-trione attendants through one-pot, multi-component contraction of aldehydes, phthalhydrazide, and dimedone under solventless status and the generality and practical tolerance of this useful and environmentally benign method are illustrated. The simple work-up, smooth reaction conditions, good to excellent yields, and reasonably short reaction times are the particular benefits of this protocol. Besides, the new nano-powdered ionic liquid was a successful and modest catalyst that could definitely be recycled and reused several times without apparent decrease in its catalytic activity.

Aims and Objective: A series of novel phthalazine derivatives was synthesized with versatile, readily accessible electrophilic and nucleophilic reagents. The newly synthesized compounds were confirmed by the results of spectroscopic measurements. Hence, their potential clinical application investigated in particular for cancer treatment. Materials and Methods: The newly synthesized compounds were characterized by spectroscopic measurements and were tested for their in vitro anticancer activity by MTT assay against human liver cancer cell line. Docking study of all the synthesized compounds was performed within the active site of the enzyme VEGFR-2 (Vascular Endothelial Growth Factor Receptor-2). Results: The quinazoline derivative 12 emerged as the most potent compound in this study with an IC50 value of 5.4 mu M. Docking study showed that the synthesized compounds were fit in the VEGFR-2 active site almost at the same position of sorafenib and vatalanib with comparable docking scores (-15.20 to -8.92 was kcal/mol). Conclusion: we have synthesized a novel series of phthalazine derivatives and evaluated their potential anticancer activity against HEPG2 cell line. The quinazoline derivative 12 emerged as the most potent compound in this study with an IC50 value of 5.4 mu M. The SAR and docking studies pointed out that rigidification of the structure resulted in better activity and better binding within the active site of VEGFR-2 as in compounds 3, 5, 6 and 12. These results introduced new phthalazine derivatives having promising activity which could lead to the development of more potent anticancer agents.

Identification of enzymes responsible for dantrolene metabolism in the human liver: A clue to uncover the cause of liver injury

Dantrolene is used for malignant hyperthermia during anesthesia, and it sometimes causes severe liver injury as a side effect. Dantrolene is metabolized to acetylaminodantrolene, which is formed via the reduction of dantrolene to aminodantrolene and subsequent acetylation. Formation of hydroxylamine during the metabolic process may be associated with liver injury. We identified the enzymes responsible for dantrolene metabolism in humans to elucidate the mechanism of liver injury. Dantrolene reductase activity was not detected in human liver microsomes, but it was detected in cytosol. Formation was increased in the presence of N-1-methylnicotineamide, which is an electron donor to aldehyde oxidase 1 (AOX1). Potent inhibitors of AOX1 and a correlation study with a marker of AOX1 activity, namely phthalazine oxidase activity, in a panel of 28 human liver cytosol samples supported the role of AOX1 in dantrolene reduction. Acetylaminodantrolene formation from aminodantrolene was highly detected in recombinant N-acetyltransferase (NAT) 2 rather than NATI. A glutathione trapping assay revealed the formation of hydroxylamine via an AOX1-dependent reduction of dantrolene but not via hydroxylation of aminodantrolene. In conclusion, we found that AOX1 and NAT2 were responsible for dantrolene metabolism in humans and that AOX1-dependent metabolism determines dantrolene-induced liver injury.
