(Elsevier, 2015)A new series of unsymmetrical cyrhetrenyl and ferrocenyl azines that were monosubstituted [(η5-C5H4)– C(R)_N–N_CH(5-NO2–2-C4H2O)]M {with M_Re(CO)3 and R_H (1a) or R_Me (1b); M_Fe(η5-C5H5) and R_H (2a) or R_Me (2b)} and ...
-
(American Chemical Society, 2013)An unusual and unique conformation of a paddle wheel type binuclear copper(II) complex containing acetate and acetamido ligands, {Cu2(μ2-O2CCH3)4}(OCNH2CH3) (1), was obtained by solvothermal synthesis. The structural ...
-
(Amer Chemical, 2020)A series of functionalized 6-alkoxy phenalenones was prepared through an unprecedented oxidative dealkylation of readily available phenalene precursors. The starting phenalenes were efficiently synthesized via an aminocatalyzed ...
-
(National Institute of Health, 1989)Almost every week, it seems, another character appears, expending the cast of DNA-binding proteins. Some of these proteins are destined for major roles, binding to DNA sequences a few hundred basepairs upstream of key ...
-
(2011)In this paper, the uptake of Cu(II) ions from an acidic aqueous solution using a continuous column packed with microcapsules containing the chelating extractant LIX-860 N-IC was examined. A simple, economical method was ...
-
(1980)Urease (EC 3.5.1.5) was purified from Spirulina maxima by ammonium sulfate precipitation, DEAE-cellulose chromatography and gel filtration on Sephadex G-200. The enzyme had maximum activity at pH 8.7, a Km for urea of 0.12 ...
