In the study of many types of biological material it has become of increasing importance to determine accurately extremely small amounts of iron. Since color reactions are, as a rule, very sensitive, calorimetric procedures are particularly useful in the microanalytical field, and several calorimetric methods have appeared in the literature on iron determination. Although the extremely sensitiv...

Objective(s): Due to the rapid increased drug resistance to Plasmodium parasites, an urgent need to achieve new antiplasmodial drugs is felt. Therefore, in this study, the new synthetic phenanthroline derivatives were synthesized with antiplasmodial activity. Materials and Methods: A series of 1,10-phenanthroline derivatives containing amino-alcohol and amino-ether substituents were synthesized...

Point-of-care testing (POCT) technology allows scientists to monitor and diagnose diseases at the patient site, much faster than classical lab-based methods. Herein, a rapid, simple, sensitive 3D printed microfluidic device integrated with smartphone-based on-chip detection is described for POCT quantification of urinary uric acid. The includes two circular inputs each connected microliter-scal...

The basic idea behind this paper was described by me in an earlier paper. 1 At that time, 1950, there was anobvious need for an actinometer capable of measuring small doses of ultraviolet light of both long and short wavelength with simplicity and accuracy. I required such an actinometer both for laboratory work and for the determination of solar ultraviolet distribution in the field. The well-...

Gravimetric, titrimetric, polarographic, optical and radiochemical methods have been reported for the determination of iron(II) and (III). Numerous reagents have also been reported for the spectrophotometric determination of Fe(II); for example, thiocyanate, dipyridine, tripyridine and 1,10-phenanthroline. The 1,10phenanthroline family has been extended to the use of dihydroxy, dimethyl, nitro ...

The title compound, [Mg(NCS)(2)(C(12)H(8)N(2))(2)], has been synthesized from the hydro-thermal reaction of MgCl(2), KSCN, 1,10-phenanthroline and H(2)O. Its structure is isotypic with the Mn(II), Fe(II), Co(II), Ni(II), Cu(II) and Zn(II) analogues. The Mg(II) cation has a slightly distorted octa-hedral geometry containing four N atoms from two 1,10-phenanthroline mol-ecules and two N atoms fro...

The crystal structure of the title complex, [Fe(C12H8N2)3][(CF3SO2)2N]2·H2O, is constructed by one octa-hedral [Fe(phen)3](2+) (phen = 1,10-phenanthroline) cation (point group symmetry 2), two Tf2N(-) [bis-(tri-fluoromethyl-sulfon-yl)imide] anions, and one water mol-ecule of crystallization (point group 2). The Fe-N bond lengths are indicative of a d (6) low-spin state for the Fe(II) ion in the...

The Zn(2+)-chelating metalloprotease inhibitor 1,10-phenanthroline (phenanthroline, 5-150 microM) elicited dose-dependent contraction of the longitudinal and circular (transverse) musculature of adult male schistosomes. At the same concentrations, phenanthroline did not cause contraction of dispersed individual muscle fibres. The phenanthroline-induced contractions were reduced by the inclusion...
