The establishment of 3-hydroxyanthranilate (3-OHAA) as an intermediate in the conversion of tryptophan to niacin or its biological equivalent in Neurospora (1, 2) has led to findings (3-5) which indicate that this compound serves a similar role in animals. Much effort to establish the details of the individual reactions involved has centered around studies of the products of the oxidation of 3-...
The reaction of 4-(dimethyl-amino)-pyridine, picolinic acid and stannic chloride yields the title monosolvated salt, (C(13)H(10)NO)[SnCl(4)(C(6)H(4)NO(2))]·CH(3)OH. The Sn(IV) atom is N,O-chelated by the picolinate ion in a cis-SnNOCl(4) octa-hedral geometry. The cation is linked to the methanol solvent mol-ecule by an O-H⋯O hydrogen bond; the solvent mol-ecule itself is a hydrogen-bond donor t...
In order to provide technical information needed by the U.S. Nuclear Regulatory Commission to evaluate the adequacy of near-surface disposal of decontamination wastes, Brookhaven National Laboratory has measured the release of organic reagents from solidified simulated decontamination wastes. The waste streams consisted of either mixed-bed ion-exchange resins or anion exchange resins equilibrat...
Ethylene is an important phytohormone that promotes the ripening of fruits and senescence of flowers thereby reducing their shelf lives. Specific ethylene biosynthesis inhibitors would help to decrease postharvest loss. Here, we identify pyrazinamide (PZA), a clinical drug used to treat tuberculosis, as an inhibitor of ethylene biosynthesis in Arabidopsis thaliana, using a chemical genetics app...
A retrospective study of 261 Vietnamese adults with severe malaria was conducted to determine the relationship between cerebrospinal fluid (CSF) levels of metabolites of the kynurenine pathway, the incidence of neurologic complications, and the disease outcome. Three metabolites were measured: the excitotoxin quinolinic acid (QA); the protective receptor antagonist kynurenic acid (KA); and the ...
