Streszczenie:
The reaction of [Co(cyclen)(OH2)OH]2+ (cyclen = 1,4,7,10-tetraazacyclododecane) with (S)-alanine at pH 7·2 gives a mixture of three [Co(cyclen)((S)-AlaO)]2+ isomers (1)–(3). These have been isolated by using both cation ion-exchange chromatography (Dowex 50 W×2, HCl eluent) and reversed phase ion-pair chromatography (C18, p-toluenephosphate in MeOH/H2O eluent). By using a combination of 1H n.m.r. techniques (n.O.e. and COSY) for solutions in (CD3)2SO the syn(N),anti(O) (1), syn(O), anti(N) (2) and syn(N), syn(O) (3) configurations have been assigned to these isomers. These have been confirmed by single-crystal X-ray analysis: [Co(cyclen)((S)-AlaO)] I2.H2O, isomer (1), P43212, a = b = 8·55150(10), c 51·8693(11) Å, Z 8, R 0·0343; [Co(cyclen)((S)-AlaO)] (ClO4)2.H2O, isomer (2), P212121, a 8·499(3), b 14·538(5), c 16·592(4) Å, Z 4, R 0·0388; [Co(cyclen)((S/R)-AlaO)] ZnBr4, a 1 : 1 mixture containing both (S)-alanine (isomer (3)) and (R)-alanine, P21/c, a 7·618(2), b 13·806(4), c 19·094(7) Å, Z 4, R 0·0726. In alkaline solution (0·1–1·0 M NaOH, 25·0°C, I = 1·0 M (NaClO4)), equilibration between (1), (2) and (3) is faster than hydrolysis to give cis-[Co(cyclen)(OH)2]++(S)-AlaO-. Time zero spectroscopic observation (300 nm) allowed the equilibrium constant, K, for the reaction [Co(cyclen)((S)-AlaO)]2+ + OH- ↔ [Co(cyclen – H)((S)-AlaO)]+ +H2O to be determined as 1·05 M-1 at 25·0°C and I = 1·0 M. The hydrolysis reaction follows the rate law kobs = kKK1K2[OH-]2/(1+K[OH-]+KK1K2[OH-]2) with k = 1·0 s-1 corresponding to rate-determining loss of (S)-AlaO- from the ring-opened complex, [Co(cyclen – H)((S)-AlaO)OH].

Streszczenie:
The model study of zinc enzyme by Zn2+–cyclen complexes (cyclen = 1, 4, 7, 10-tetraazacyclododecane) disclosed the intrinsic properties of zinc(II) as having strong anion affinities and yet the resulting Zn2+–anion bonds have a labile nature. The basic understanding has evolved into novel selective nucleobase recognition by the Zn2+–cyclen complexes. The Zn2+–aromatic pendant cyclen complexes selectively and effectively bind to thymine T (or uracil U) in single- and double-stranded DNA (or RNA). The Zn2+ complexes work like molecular zippers to break A–T pairs in double-stranded DNA, as proven by various physicochemical and DNA footprinting measurements. Moreover, these Zn2+–complexes affect relevant biochemical and ultimately biological properties such as inhibition of a transcriptional factor and antimicrobial activities.

Streszczenie:
A series of cyclam- and cyclen-derived salts are described in the present work; they were designed specifically to gain insights into their structure and antibacterial activity towards Staphylococcus aureus and Escherichia coli, used respectively, as Gram-positive and Gram-negative model organisms. The newly synthesized compounds are monosubstituted and trans-disubstituted tetraazamacrocycles that display benzyl, methylbenzyl, trifluoromethylbenzyl, or trifluoroethylbenzyl substituents appended on the nitrogen atoms of the macrocyclic ring. The results obtained show that the chemical nature, polarity, and substitution patterns of the benzyl groups, as well as the number of pendant arms, are critical parameters for the antibacterial activity of the cyclam-based salts. The most active compounds against both bacterial strains were the trans-disubstituted cyclam salts displaying CF3 groups in the para-position of the aromatic rings of the macrocyclic pendant arms. The analogous cyclen species presents a lower activity, revealing that the size of the macrocyclic backbone is an important requirement for the antibacterial activity of the tetraazamacrocycles. The nature of the anionic counterparts present on the salts was found to play a minor role in the antibacterial activity.

Streszczenie:
An abinitio MO-SCF calculations have been performed with a minimal Gaussian lobe basis set for numerous Mg(II) 1,4,7,10-tetraazacyclododecane (cyclen) configurations. Mg(II) shows a strong interaction with all functional groups of cyclen. The strongest interaction occurs when magnesium points to the cavity and perpendicular to the ligand plane. However, in the complex formation processes, the ion does not prefer to move along this direction because of the repulsive interaction with the NH functional groups. The favourable path for entering the cavity of the ligand encloses an angle of 30° with the z axis and lies in the plane between the opposite NH groups. Keywords: cyclen, macrocyclic effect, complex formation, favourable path, abinitio calculations.

Streszczenie:
An efficient protocol for the direct synthesis of N-tetraalkylated derivatives of the azamacrocycles cyclam and cyclen has been developed, using a partially miscible aqueous–organic solvent system with propargyl bromide, benzyl bromide, and related halides. The method works most effectively when the reaction mixture is shaken, not stirred. A crystal structure of the N-tetrapropargyl cyclam derivative 1,4,8,11-tetra(prop-2-yn-1-yl)-1,4,8,11-tetraazacyclotetradecane diperchlorate is reported.
