1,10-Phenanthroline is an inhibitor of metallopeptidases, with one of the first observed instances reported in carboxypeptidase A. [11] Inhibition of the enzyme occurs by removal and chelation of the metal ion required for catalytic activity, leaving an inactive apoenzyme . 1,10-Phenanthroline targets mainly zinc metallopeptidases, with a much ...
1,10-Phenanthroline (phen) is a heterocyclic organic compound. It is a white solid that is soluble in organic solvents. It is a white solid that is soluble in organic solvents. The 1,10 refer to the location of the nitrogen atoms that replace CH's in the hydrocarbon called phenanthrene .
To overcome this, a second pair of resistors R′ 1 and R′ 2 form a second pair of arms of the bridge (hence 'double bridge') and are connected to the inner potential terminals of R s and R x (identified as P 2 and P′ 2 in the diagram). The detector D is connected between the junction of R 1 and R 2 and the junction of R′ 1 and R′ 2. [2]
1,10-Phenanthroline-5,6-dione is an organic compound with the formula C 12 H 6 O 2 N 2. It is the quinone derivative of 1,10-phenanthroline . The compound exhibits many reactions, including condensations with diamines to give quinoxalines and decarbonylation to give a diazafluorenone .

Relative to 1,10-phenanthroline, neocuproine bears steric bulk flanking the nitrogen donor sites. A major consequence is that complexes of the type [M(neocuproine) 3 ] n+ are disfavored, in contrast to the situation with phenanthroline ligands that lack substitution in the 2,9 positions. [ 6 ]
Ferroin is the chemical compound with the formula [Fe(o-phen) 3]SO 4, where o-phen is an abbreviation for 1,10-phenanthroline, a bidentate ligand. The term "ferroin" is used loosely and includes salts of other anions such as chloride. [1] Ferroin is one of many transition metal complexes of 1,10-phenanthroline.
Thus, (CH 3) 4 Sn and SnCl 4 are allowed to react at temperatures between 100 °C and 200 °C to give (CH 3) 3 SnCl as a product: SnCl 4 + 3 (CH 3) 4 Sn → 4 (CH 3) 3 SnCl. A second route to trimethyltin chloride utilizing tetramethyltin involves the reaction of mercury(II) chloride to react with (CH 3) 4 Sn. [2] 4 HgCl 2 + 4 (CH 3) 4 Sn → 4 ...
