Nucleic acid sequence analogues, in particular tRNA analogues comprising in the place of a 3'-terminal adenosine a 3'-terminal 2'-deoxy-2'-thioadenosine are able to react site-specifically with weakly activated amino acid derivatives (e.g. phenylthioesters ...
The invention relates to human O6-alkylguanine-DNA alkyltransferase (hAGT) mutants showing, when compared to the wild type human AGT, two or more advantageous properties selected from (a) reduced DNA interaction; (b) localization of the expressed protein i ...

In the presence of a catalytic amt. of (Schiff base)Al(III)Cl complex (Schiff base of (R,R)-1,2-cyclohexanediamine with 3,5-di-tert-butyl-2-hydroxybenzaldehyde), reaction between alpha -isocyanoacetamides and aldehydes afforded the corresponding 5-aminooxa ...
The present work describes synthetic concepts for the coupling of peptides to polyphenylene dendrimers (PPDs). Novel functionalized cyclopentadienones have been synthesized whose Diels-Alder cycloaddition with various core molecules leads to polyphenylene ...
The basic aqueous coordination chemistry of Ru-II has been studied using the catalytically important TPPTS phosphine (TPPTS = trisodium salt of 3,3 ',3 ''-phosphinetriylbenzenesulfonic acid) and small gas molecules (H-2, CO, N-2) as ligands. As a result, n ...
In the presence of moderately strong acids in MeCN, Co complexes with BF2-bridged diglyoxime ligands are active catalysts for the redn. of protons to H2 at potentials as pos. as -0.28 V vs. SCE. [on SciFinder (R)] ...
16-Membered meta,para-cyclophanes mimicking the vancomycin binding pocket (D-O-E ring) are designed and synthesized. The structural features of these biaryl ether contg. macrocycles are: (a) the deletion of the carboxyl group of vancomycin's central amino ...
alpha -Isocyano-beta -phenylpropionamide is synthesized from the corresponding amino acid in excellent yield. The unique reactivity of this bifunctional compd. is exploited for the development of novel multicomponent synthesis of 5-aminooxazole, pyrrolo[3, ...
The trinuclear Ru complexes [RuCl2(PAd2Bu)]3 (1) and [RuCl2(PtBu2Cy)]3 (2) were obtained by reaction of [(p-cymene)RuCl2]2 with 2 equiv of the resp. sterically demanding phosphine. Crystallog. analyses of 1 and 2 show that the three metal fragments are con ...
A series of trans-platinum(IV) complexes with functionalized aromatic carboxylate ligands, cis,cis,trans-Pt(NH3)2Cl2(CO2C6H4R)2 (R = H (3), p-vinyl (4), p-methoxy (5), p-iodo (6), ...
