Grafting of a new carbohydrate UV-reactive molecule, an azidophenyl lactamine (AzPhLac), was achieved on fibers of three different diameters: 12, 18, and 32 microm. Adsorption of AzPhLac on fibers was obtained by using the dip-coating method in solution. The effect
3-Methyl-1-phenyltriazene and a series of ring-substituted derivatives (4-methylphenyl, 4-chlorophenyl, and 2,4,6-trichlorophenyl), structurally related benzenediazonium fluoborates and phenyl azides, as well as the recently isolated [1-methyl-3-(2,4,6-trichlorophenyl)-2-triazeno]methyl-beta-D-glucopyranoside uronic acid, were studied for their mutagenic activity in Salmonella typhimurium strains. Of these compounds

Covalent immobilization of unmodified biological materials as proteins has been performed through a one-step and soft method. This process is based on a polyazidophenylene layer derived from the electroreduction of the parent salt 4-azidobenzenediazonium tetrafluoborate on gold substrates. The wavelength
New lipid analogs mimicking the abundant membrane phospholipid phosphatidylcholine were developed to photocrosslink proteins interacting with phospholipid headgroups at the membrane interface. In addition to either a phenylazide or benzophenone photoactivatable moiety attached to the headgroup, the lipid analogs contained
Two new photoreactive dATP analogs, N(6)-[4-azidobenzoyl-(2-aminoethyl)]-2'-deoxyadenosine-5'-triphospha+ ++ te (AB-dATP) and N(6)-[4-[3-(trifluoromethyl)-diazirin-3-yl]benzoyl-(2-aminoethyl) ]-2 '-deoxyadenosine-5'-triphosphate (DB-dATP), were synthesized from 2'-deoxyadenosine-5'-monophosphate in a six step procedure. Synthesis starts with aminoethylation of dAMP and continues with rearrangement of N(1)-(2-aminoethyl)-2'-deoxyadenosine-5'-monophosphate to N(6)-(2-aminoethyl)-2'-deoxyadenosine-5'-monophosphate (N(6)-dAMP). Next, N(6)-dAMP
