AB  - Two hydroxyanthraquinones, alizarin and purpurin, that have been used throughout
history as a natural pigment, were extracted from roots of Rubia tinctorum from
Serbia. As substances with important chemical activities and, therefore, with wide
applications (for example in dyeing textile fabrics as well as in pharmacy because of
their anti-inflammatory, anti-cancer, antiviral, antimicrobial and antioxidant activities,
etc.) they were analyzed in the kinetically very sensitive Bray–Liebhafsky (BL)
oscillatory reaction. However, although they are both, hydroxyanthraquinones it is
shown that their interactions with BL nonlinear reaction system differ significantly.
Consequently, two different reactions were used to explain the mechanism of their
chemical activities. The numerical simulations based on a standard model of the BL
oscillatory reaction together with proposed reactions due to alizarin/purpurin interactions
with a matrix are correlated with experimental investigations. Moreover, it
is shown that very small amounts of alizarin and purpurin (from about 1 × 10–7 M)
produce the response of the BL matrix such that micro-quantitative analysis based
on the BL oscillatory reaction can be successfully performed in this reaction system.
The linear response of the BL matrix on the presence of alizarin and purpurin
(necessary for microquantitative determination) is analyzed as a function of two
concentration sensitive parameters: pre-oscillatory period τ1 and potential shift after
perturbation ΔE.

AB  - Twenty five 4-aminomethylidene derivatives obtained from 3-phenyl-2-pyrazolin-5-one and 1,3-diphenyl-2-pyrazolin-5-one were synthesized and tested for their antiproliferative activity against human breast cancer MDA-MB-361 and MDA-MB-453 cell lines. The compounds derived from 1,3-diphenyl-2-pyrazolin-5-one exhibited the most remarkable activity in the treatment of both cell lines. In vitro antiproliferative activities were accompanied by an important apoptotic fraction of both cell lines; also, compounds inhibited key endothelial cell functions implicated in invasion and angiogenesis. QSAR methods were performed in order to analyze the influence of structural features of the compounds investigated on the antiproliferative potential on MDA-MB-361 and MDA-MB-453 cancer cells. One-parameter heuristic analysis was performed and different whole molecule and fragmental descriptors were considered for rationalization of mechanism of interaction of these compounds with active place of hypothetical target included in tumorigenesis.
