Photoaffinity-labeled Auxins: Synthesis and Biological Activity.
Two light-sensitive analogs of 2,4-dichlorophenoxyacetic acid, namely 4-azido-2-chlorophenoxyacetic acid and 3-azido-5-chlorophenoxyacetic acid, have been synthesized for use as auxin photoaffinity labels. The preparation and biological activity of the compounds are described. Both contain the photolabile azido group; the 2,4-substituted compound shows auxin activity and the 3,5-substituted com...
متن کاملAzido auxins: synthesis and biological activity of fluorescent photoaffinity labeling agents.
Three auxin analogs, 4-, 5-, and 6-azido-3-indoleacetic acid (4-N(3)-IAA, 5-N(3)-IAA, and 6-N(3)-IAA) have been synthesized for use as fluorescent photoaffinity labeling agents. The pK(a) values of these compounds (4-N(3)-IAA, 4.67; 5-N(3)-IAA, 4.65; 6-N(3)-IAA, 4.66; all +/- 0.04) are experimentally indistinguishable from the pK(a) of 3-indoleacetic acid (IAA, 4.69 +/- 0.04). The auxin activit...
متن کاملDopamine transport sites selectively labeled by a novel photoaffinity probe: 125I-DEEP.
The dopamine transporter was labeled using a photosensitive compound related to GBR-12909, 125I-1-[2-(diphenylmethoxy)ethyl]-4-[2- (4-azido-3-iodophenyl)ethyl]piperazine (125I-DEEP). 125I-DEEP bound reversibly and with high affinity to the dopamine transport protein in the absence of light and could be covalently attached to the protein following exposure to UV light. In rat striatal homogenate...
متن کاملA photoaffinity-labeled green leaf volatile compound 'tricks' highly selective and sensitive insect olfactory receptor neurons.
The sex pheromone of the scarab beetle, Phyllopertha diversa, is emitted by females and specifically detected by olfactory receptor neurons in the male and female antennae. Single sensillum recordings showed that, in contrast to the less sensitive pheromone sensilla in females, olfactory receptor neurons in the male antennae had a low threshold (1 ng), which rivals those of moths. The male and ...
متن کاملSynthesis and properties of diazirinyl organo-platinum compounds for manipulations of photoaffinity labeled components.
Synthesis of diazirinyl organo-platinum complexes, which specifically interact with purine base, characterization of photoreactivity and interaction between guanosine 5'-monophosphate (GMP) were examined. The results indicated that the diazirinyl organo-platinum complex was useful for manipulations of photoaffinity labeled components.
