Spectroscopic Studies on the Interaction of Co(II) Tetrapyridinoporphyrazine with Synthetic Polynucleotides and DNA
Interactions of cationic tetrakis (N,N´,N´´,N´´´-tetramethyltetra-3,4-pyridinoporphyrazinatocobalt(II) (Co(tmtppa)) with synthetic polynucleotides, poly(A-T), poly(G-C) and calf thymus DNA have been characterized in 5 mM phosphate buffer, pH 7.2, by optical absorption and fluorescence spectroscopy. The appearance of hypochromicity effect and the red shift in UV-Vis spectrum of porphyrazine was ...
متن کاملBatch experimental studies of Hg(II) ion removal from aqueous solution using seven synthetic polymers
In this work application of seven synthetic polymers as adsorbents for the removal of Hg(II) from aqueous solution was studied. The equilibrium studies are systematically carried out in a batch process, covering various process parameters that include agitation time, adsorbent dosage, and pH of the aqueous solution. Variations of Hg(II) concentration in solution have been studied through measur...

متن کاملStudies on the Effect of Synthetic Surface-active Materials on Bacterial Growth. II.
In a previous communication (Katz and Lipsitz, 1935), the effect of a certain synthetic surface-active material on the growth of Mycobacterium smegmatis was discussed; this work has now been extended to include three more compounds, varying in chemical structure. These materials possess substantially the same properties as the alkylated naphthalene sulfonate originally employed, i.e., remarkabl...
متن کاملInteractions of synthetic estrogens with human estrogen receptors.
Synthetic estrogens have diverse chemical structures and may either positively or negatively affect the estrogenic signaling pathways through interactions with the estrogen receptors (ERs). Modeling studies suggest that 4-(1-adamantyl)phenol (AdP) and 4,4'-(1,3-adamantanediyl)diphenol (AdDP) can bind in the ligand binding site of ERalpha. We used fluorescence polarization (FP) to compare the bi...
