Abstract:: Now days, it is of utmost important to design synthetic methods; which can be utilized for the generation of substances that will minimize toxicity to health of human and the environment. The utilization of acid catalysts generates lots of corrosive and harmful wastes which has to be treated with appropriate alkalis. Hence, it generates lots of sludge and alarms environmental issues of its storage and disposal. Zeolites and Zeotypes; by virtue of their peculiar properties; such as specific morphology, porosity and residing acidity; attracting enormous attention as they replaces harmful acid catalysts efficiently and also reduces chemical waste in industrial process; Hence emerged as new plethora in the field of “Green Chemistry”.

It was shown by the polarographic data of the complexes between antracycline antibiotics and DNA that in contrast to their biological inactive aglycones and other antracyclinones, a cooperative interaction of the intercalating chromophore as well as the sugar residue of the anthracycline molecules, is generally responsible for the complex formation with DNA.The high complex binding constants of the antracyclines daunomycin, nogalamycin, galirubin A and galirubin B measured in dimethylsulfoxid-buffer solution are in the same order of magnitude as those of actinomycins. On the other hand, only a weak binding ability of the aglycones daunomycinon, ε-pyrromycinon and aklavinon, as well as of other investigated anthracyclinones and model hydroxyanthraquinones, could be observed.No significant influence of the number and positions of the chromophore hydroxyls could be noticed.The results suggest that the first outerphase addition of the sugar residues to the backbone of the helix gives the necessary space of time for the slower intercalation process of the planar chromophore.In the case of denatured DNA, the antibiotic-DNA-complex has a lowered stability.The important role of the sugar residue for the binding mechanism strongly suggests that modifications of the nature and position of the basic sugar residue should be most valuable for the synthesis of new effective anthracyclines.

Modified Sensor

A sensitive and simple modified sensor was prepared by electrodeposition of diphenylamine sulfonic acid (DPSA) to the glassy carbon electrode surface by cyclic voltammetry (CV) technique. The electrooxidation of epinephrine (EP) was accomplished by CV and differential pulse voltammetry at poly(DPSA) modified sensor. As a result of the findings, the current values were enhanced and both substances were separated at the modified sensor compared to the bare electrode. There was linearly between the oxidation current and concentration of EP from 0.2 to 100 μM in phosphate buffer solution at pH 7.0. The limit of detection was 5.0 nM and the sensitivity was 0.4205 μA/μM. The determination of EP was successfully and satisfactorily carried out in real samples such as human blood serum and urine at the poly(DPSA) sensor. To the best knowledge of this work, this is the first study that detect the EP in the presence of ascorbic acid at poly(DPSA) sensor in the literature.
