Show moreNew organometallic containing materials were synthesized by the reaction of Group IVB metallocene dichlorides of the form Cp2MCl2 where M = Ti, Ar, and Hf with Hematoporphyrin IX using the interfacial condensation polymerization technique. The structural characterization was accomplished using infrared and mass spectroscopy and elemental analysis. The results obtained from these techniques showed the presence of the metal ester and ether bonding as evidence that the reaction occurred. The product derived from titanocene dichloride, 12-A, exhibited growth inhibition characteristics towards the Candid albicans and Staphylococcus aureus microorganisms. From the preliminary metal adsorption studies it was shown that this product also bound nickel ions.

One of the most common chemotherapeutic drugs in use today is cis-DDP. While this substance has been found useful in the treatment of various malignant neoplasias, it also has many adverse side effects. Recently, polymeric cis-DDP analogs have been prepared using potassium tetrachloroplatinate and various diamines. Testing of these polymeric analogs has shown that some are biologically active while others are biologically inactive. The goal of this research was to investigate the possible...

While this substance has been found useful in the treatment of various malignant neoplasias, it also has many adverse side effects. Recently, polymeric cis-DDP analogs have been prepared using potassium tetrachloroplatinate and various diamines. Testing of these polymeric analogs has shown that some are biologically active while others are biologically inactive. The goal of this research was to investigate the possible reasons for the differences in biological activity which had been observed. The biological activity of the diamine components, the molecular weight of the polymers, and the degradation of the polymers were examined to determine if any of these properties of the polymers could be correlated to their biological activities.

The structures were determined using infrared and mass spectroscopy. Further characterization involved elemental analysis, thermal analysis, and solubility studies. For the organotin products, the biological activities towards selected microorganisms were determined. The products exhibited selective inhibition of Candida Albicans, the microorganism most responsible for yeast infections in man. The titanocene-containing polyethers exhibited flexibility when derived from longer chained polyethylene glycols, but were inflexible when shorter chained polyethylene glycols were used.

For the chelating agents oxalic acid and disodium oxalate, the extent and the rate of magnetic susceptibility decrease are discussed with respect to their concentration, site of chelation, exposure time and selectivity. The magnetic susceptibility measurements were carried out with a Superconductor Characterization Cryostat and the surface analysis was accomplished by employing Auger Electron Spectroscopy (AES) and X-Ray Photoelectron Spectroscopy (XPS). The results show that the solution containing oxalic acid can remove copper atoms from the superconductor surface. The extent and the rate of superconductivity decrease can be controlled by changes in concentration, addition sequence and exposure time.

Show moreNitric acid can drive oxidation reactions of paraffins producing nitroparaffins and other oxidation products. Presented here is a study on the aqueous liquid phase nitric acid oxidation of paraffin oil supported on PTFE particles. The goals ofthis study are: 1. To evaluate the effectiveness of nitric acid in removing paraffin oil from PTFE particle surfaces. 2. To evaluate the effects of nitric acid driven reactions with paraffin oils under varying reaction conditions. 3. To evaluate FTIR Diffuse Reflectance Spectroscopy, DRIFT, as a tool to accomplish the quantitative analysis of this process. These goals have been achieved employing analysis by FTIR Diffuse Reflectance, which provides a ready means of quantifying paraffin removal. Paraffin removal generally increases with time, temperature and nitric acid concentration and can be described by known kinetics including activation energy and region of unity relationship between the log of the rate constant verses Hammett acidity function.

The biological potential of the products was tested against selected microorganisms and Balb/3T3 cell lines. One of the products showed activity in the 0.2mug/ml range, one hundredth of that of similar compounds. Germination experiments using the PGH incorporated polymers were performed on sawgrass and cattail seeds as well as selected vegetable seeds and compared to a control. Sawgrass germination, typically in the 0--2% range were increased to about 60% through the treatment with kinetin-containing polymers.

Show moreWe have synthesized intermediates towards the preparation of a polyphosphonate ester containing L-dopa for the potential treatment of Parkinson's disease. A synthetic strategy was devised to be more reproducible than the original strategy. We discovered some very interesting chemistry of one of the intermediates produced from this new scheme. We synthesized L-N-(butyloxycarbonyl)-3-(3-hydroxy-ethyl-4-(benzyloxy)-phenyl)alanine benzylester, a compound containing a secondary alcohol moiety that had a unique set of characteristics. Upon reduction of the N-(tert-butyloxycarbonyl)-3-(3-acetyl-4-benzyloxyphenyl)-L-alanine benzylester, which contained a ketone moiety, to produce the secondary alcohol, we discovered that the materials that were formed included a pair of diastereomers of the secondary alcohol, each diastereomer also exhibiting two individually stable conformational isomers. We believe that the conformational isomers were generated by rotation of the C-N bond of the BOC carbamate, and were so stable that they could be separated by HPLC and NMR techniques. Energy optimization studies and molecular modeling techniques were performed using HyperChem, and rotational barrier energy values were calculated for the different conformational isomers for each of the diastereomers. HPLC and NMR techniques were also used to obtain information about these materials. Using the calculated data from these studies, and analyzing the HPLC chromatograms and NMR spectra we were able to fully determine the assignments for the diastereomers and the individual conformational isomers. We discovered that the SS form was synthesized preferentially over the SR form and that in both cases the E conformation was energetically more stable than the Z form. Octanol/water partition coefficient values (Log P0ct) were also determined and compared to L-dopa and dopamine. We concluded that the values for the dimeric compound that we synthesized and many of its potential products of degradation were significantly higher than that for both L-dopa and dopamine. This may be an indication that this material has a higher degree of lipophilicity than L-dopa itself, having more potential to cross the blood brain barrier. We believe that these intermediate materials serve as good indication of how a polyphosphonate ester containing L-dopa would compare as a potential drug for Parkinson's disease.

The specific goal is the synthesis of organotin polymers containing amino acids, in this case the diamino acid diglycine. The desired materials were synthesized with percent yields ranging from 32-99%. The products were synthesized employing the interfacial polymerization technique. The polymers were then characterized utilizing the following physical characterization techniques: light scattering photometry (LS), Infrared spectroscopy (IR), nuclear magnetic resonance spectroscopy (NMR), and matrix assisted laser desorption mass spectroscopy (MALDI). Physical characterization showed evidence of formation of desired adducts in addition to data that was consistent with the formation of materials containing multiple repeat units. The materials were then analyzed for biological activity. The synthesized materials displayed the ability to inhibit tested cancer cell lines.
