A structurally well-defined THF-free cationic half-sandwich scandium aminobenzyl complex serves as a novel catalyst for the first copolymerization of 1-hexene with dicyclopentadiene to give the random copolymers with a wide range of 1-hexene contents (32-70 mol%) unavailable previously.
The specificity of the reaction of antipurin-6-oyl sera with thermally denatured DNA has been studied by means of hapten inhibition techniques. The relative order of effectiveness of various haptens as inhibitors of the complement fixation reaction between DNA and antipurin-6-oyl serum was found to be comparable to their relative order of effectiveness as inhibitors of the precipitin reaction b...
A novel series of {4-[(2-amino-6-chloro-9H-purin-9-yl)methyl]-1H-1,2,3-triazol-1-yl}alkylphosphonates and {4-[(2-amino-6-oxo-1,6-dihydro-9H-purin-9-yl)methyl]-1H-1,2,3-triazol-1-yl}alkylphosphonates as acyclic analogues of guanosine were synthesized and assessed for antiviral activity against a broad range of DNA and RNA viruses and for their cytostatic activity toward three cancerous cell line...
The primary sequence was established for two lysine tRNA isoacceptors which differ in abundance during development in Bacillus subtilis. Both tRNAs shared the same primary sequence but differed in the degree of post-transcriptional modification in the anticodon loop. The earlier eluting species, tRNA lys 1, had an unmodified C in position 32 and a mixture of N-[9-beta-ribofuranosyl) purin-6-ylc...
Irreversible inhibitors that modify cysteine or lysine residues within a protein kinase ATP binding site offer, through their distinctive mode of action, an alternative to ATP-competitive agents. 4-((6-(Cyclohexylmethoxy)-9H-purin-2-yl)amino)benzenesulfonamide (NU6102) is a potent and selective ATP-competitive inhibitor of CDK2 in which the sulfonamide moiety is positioned close to a pair of ly...
Complexation with cyclam increases the rate of reduction of perchlorate ion by TiIII (in acidic, aqueous, 4 mol dm–3 LiCl solutions at 25 °C) relative to the rate of the corresponding reduction of Ti3+. A modified cyclam with pendant amine and p-aminobenzyl functional groups is more effective in this regard than is cyclam itself. Both redox reactions are acid catalyzed. The data is consistent w...
