Studies on Amination of Porphyrins – In Search for Effective and Renewable Nucleophilic Aminating Reagent

Studies on amination of electrophilic porphyrins, with the use of 4-amino-4H-1,2,4-triazole and various sulfenamides, are described. Products of direct amination were observed (formed according to VNS mechanism) which were usually accompanied with other substitution of hydrogen products (formed according to ONSH mechanism).

Preparation and Antimicrobial Screening of Novel 2, 2-dichloro-cyclopropane–cis-dicarbamates and Comparison to their Alkane and cis-Alkene Analogs

A series of novel compounds containing both cis-gem-dichlorocyclopropane and aromatic carbamate moieties 9a-f were prepared, along with analogues of containing four carbon spacers, both alkane 7a-f and cis alkene 8a-f. Screening against representative gram negative bacteria, yeast and gram positive bacteria showed excellent trends for antimicrobial activity against gram positive bacteria. The cis-gem-dichlorocyclopropane spacer targets (Series 9) exhibited the strongest activity with three out of the six compounds from series 9 having activity against (S. aureus 29213) that are stronger than that of commercial antibiotics tested.

Template Polymerization of Methacrylic Acid and Acrylamide Monomers in the Presence of Polyethylene Oxide

Polyethylene oxide-grafted-polymethacrylic acid (PEO-g-PMAA) copolymer and polyethylene oxide-grafted-polyacrylamide (PEO-g-PAAm) copolymer materials are recieving growing attention in many fields, especially their applications in medicine. This paper cover the preparation and the physicochemical characterization of these material in the form of ternary system of polyethylene oxide –polymethacrylic acid-polyacrylamide (PEO-PMAA-PAAm) interpolymer complex (IPC). The presence of hydrogen bondings were studied by FTIR analysis and equilibrium swelling ratio measurements which also give information about the molecular transport of liquid into the polymer matrix. Thermal behaviour of different monomers mol ratios of the IPC's were explained in terms of their Tm's and Tg's values. The homogeneous morphology with interconnected microsphers of the prepared IPC have a competable physicochemical properties of which can be used in bio-filtration process. Moreover Molecular mechanics calculations were used to shed some light about the structure and stability of the IPC.

Volatile Constituents of Leaves and Bulbs of Gynandriris Sisyrinchium and their Antimicrobial Activities

The essential oils obtained by hydrodistillation from the leaves and bulbs of Gynandriris Sisyrinchium L. growing in the northern region of Jordan (Irbid) were investigated by GC and GC/MS. The major constituents of the leaves oil were 3,7,11,15-tetramethyl-2-hexadecen-1-ol (20.24%), ledene oxide (II) (12.62%),  furfural (9.80%) and trans-sabinol (3.58%). The bulb oil was found to contain phenylacetaldehyde (21.85%), 8,9-dehydroneoisolongifolene (12.10%), 8S,14-cedranediol (8.36%) and furfural (3.66%) as the major constituents. The antibacterial activity of essential oils mixture of the bulbs and leaves were evaluated for their antimicrobial activity against ten bacterial isolates using agar disc and agar well diffusion methods. The Gram-positive bacterial isolates including Bacillus cereus, ATCC11778 and Bacillus subtilis, ATCC6633 were the most susceptible to the tested oil mixtures.  In contrast, the tested essential oils showed either no inhibitory effect against Klebsiella pneumoniae, ATCC 10031 and Serratia marcescens, ATCC 27117 or moderate effects against the remaining tested Gram-negative bacterial isolates.

Low Barrier Hydrogen Bond (LBHB) Interactions in the Solid State Crystal Structures of Phthalate Salts Based on Trisubstituted Guanidinium Cations

The hydrogen phthalate salt N, N', N''- tricyclohexylguanidinium hydrogen phthalate {C(HNcyclohexyl)3}+HPHT-(1) was prepared and the structure was determined by X-ray diffraction analysis and characterized by elemental analysis, NMR and IR spectroscopy. The hydrogen-bonding interactions of this colorless solid have been explored in order to examine the potential of intermolecular and intramolecular interactions and their influence on the extended structure that was observed. Compound 1 crystallizes in the monoclinic space group P2(1)/n, with a = 10.6270 (13) Ă, b = 16.809 (2) Ă, c = 15.1657 (18) Ă and β = 102.978 (2)º; Z = 4. The crystal data indicate that the anion displayed a characteristic intramolecular, low barrier hydrogen bond (LBHB) (S(7) motif) via O-HO interaction. The primary structure combines two cyclic associations, a 16-membered ring (R44(16) notation) and a large 46-membered ring (R44(46) notation), through N-H…O hydrogen-bonding interactions. The structure of 1 is compared with the analogue salts N, N', N''- triisopropylguanidinium phthalate 2 and N, N', N''- triisopropylguanidinium hydrogen maleate 3.
