Synthesis and biological evaluation of (18)F-labeled Fluoroethoxy tryptophan analogues as potential PET tumor imaging agents.

Aristeidis Chiotellis et al.

Molecular pharmaceutics, 11(11), 3839-3851 (2014-07-06)

As a continuation of our research efforts toward the development of tryptophan-based radiotracers for tumor imaging with positron emission tomography (PET), three new fluoroethoxy tryptophan analogues were synthesized and evaluated in vivo. These new tracers (namely, 4-(2-[(18)F]fluoroethoxy)-dl-tryptophan ([(18)F]4-FEHTP), 6-(2-[(18)F]fluoroethoxy)-dl-tryptophan ([(18)F]6-FEHTP)

No effect of oral L-tryptophan or alpha-lactalbumin on total tryptophan levels in breast milk.

European neuropsychopharmacology : the journal of the European College of Neuropsychopharmacology, 25(6), 779-787 (2015-04-01)

Postpartum depression (PPD) is the most common complication of childbearing with a 13% prevalence rate. Sleep disturbances are also common, particularly during early postpartum. In theory, l-tryptophan could improve sleep and reduce depressed mood in early postpartum; however, the first

Minimal change multiple system atrophy: an aggressive variant?

Helen Ling et al.

Movement disorders : official journal of the Movement Disorder Society, 30(7), 960-967 (2015-04-10)

Glial cytoplasmic inclusions containing α-synuclein are the pathological hallmark of multiple system atrophy (MSA). Minimal change (MC-MSA) is an unusual MSA subtype with neuronal loss largely restricted to the substantia nigra and locus coeruleus. Immunohistochemistry on selected brain regions and
