The significant superior binding of [C.sub.2] and [C.sub.4] compared to other complexes is possibly owing to the 1,10-phenanthroline ring analogue as coligand in the respective complexes, which favours the interaction with the DNA through [pi] - [[pi].sup.*] interaction and H-bonding [59].
The compounds (1-4) were reacted with the nitrogen and phosphorous donor ligands like triphenylphosphine, pyridine, 2,27 -bipyridine, and 1,10-phenanthroline in dichloromethane in appropriate stoichiometries.

Cluster 1 contains iodochlorohydroxyquinoline, 8-hydroxyquinoline, 1,10-phenanthroline monohydrate, and quinoline (Figure 2).
The CCm-Tf-degrading activity in the samples from IPF patients was not altered by incubation on the CCm-Tf film coated with a mixture of aprotinin and elastinal (serine proteinase inhibitors) (Figure 5, B), but it was completely abolished in the film coated with a mixture of the serine proteinase inhibitors and 1,10-phenanthroline (a metalloproteinase inhibitor) (Figure 5, C).

PAN indicator: is a mixture of sulfuric acid solution, ammonium sulfate, 1,10-phenanthroline solution (20%), L-ascorbic acid solution (2%) and acetic-sodium acetate buffer (pH [approximately equal to] 4.5).
Class-specific inhibitors of serineprotease (phenylmethylsulfonyl fluoride (PMSF) 4mM) and metalloprotease (1,10-phenanthroline 5mM) [13, 17, 27] were employed to determine the specific kinds of proteases produced.
Zymograms were incubated in the presence of 5 mmol/L EDTA and 2 mmol/L 1,10-phenanthroline for inhibition studies (31); activation of zymogens was achieved with 2 mmol/L p-aminophenyl-mercuric acetate (31).

Ten millimoles of 1,10-phenanthroline was added in the extraction buffer as a nuclease inhibitor and the hexadecyltrimethylammonium bromide step was omitted.
