The kynurenine pathway and the brain: challenges, controversies and promises [PDF]

open access: yes, 2017
Research on the neurobiology of the kynurenine pathway has suffered years of relative obscurity because tryptophan degradation, and its involvement in both physiology and major brain diseases, was viewed almost exclusively through the lens of the well ...

10-Hydroxybenzo[h]quinolin-1-ium tetrachlorido(pyridine-2-carboxylato-κ2N,O)stannate(IV) methanol monosolvate

open access: yesActa Crystallographica Section E, 2012
The reaction of 4-(dimethylamino)pyridine, picolinic acid and stannic chloride yields the title monosolvated salt, (C13H10NO)[SnCl4(C6H4NO2)]·CH3OH. The SnIV atom is N,O-chelated by the picolinate ion in a cis-SnNOCl4 octahedral geometry.

A scalable synthesis of the (S)-4-(tert-butyl)-2-(pyridin-2-yl)-4,5-dihydrooxazole ((S)-t-BuPyOx) ligand

open access: yesBeilstein Journal of Organic Chemistry, 2013
An efficient method for the synthesis of the (S)-4-(tert-butyl)-2-(pyridin-2-yl)-4,5-dihydrooxazole ((S)-t-BuPyOx) ligand has been developed. Inconsistent yields and tedious purification in known routes to (S)-t-BuPyOx suggested the need for an efficient,
