The Steroid Sulfatase Inhibitor (p-O-Sulfamoyl) - Tetradecanoyl Tyramine (DU-14) Enhances Memory Retention in Passive Avoidance in Rats with Hippocampal Cholinergic Deficit
… amnesia. p-O-(Sulfamoyl) - tetradecanoyl tyramine (DU-14) is a steroid sulfatase inhibitor (SSI) that prevents the conversion of DHEAS to DHEA thereby increasing the concentration of sulfated neurosteroids to potentiate the effect of endogenous DHEAS. To determine whether DU-14 could …

Expression of tyramine β – hydroxylase and tyrosine hydroxylase genes in response to odor valence in the brain of the honey bee, Apis mellifera
… rate limiting enzymes in OA and DA synthesis, tyramine β – hydroxylase (tbh) and tyrosine hydroxylase (th), respectively, in response to conditioned odor valence. Populations of tbh- and th-expressing neurons in 6 and 4 locations of the bee brain, respectively, were measured. I discovered …

Genetic Functional Dissection of the Synaptic Output of a Dual-Function Integrating Neuron
… releases both glutamate and the biogenic amine tyramine (~noradrenaline) and forms gap junctions with neurons that govern various aspects of C. elegans locomotion. RIM is the major source of tyramine in C. elegans, and this output is known to extend reversal length of spontaneous and evoked …

Aversive Olfactory Imprinting in Caenorhabditis Elegans
… formation neurons synthesize the neuromodulator tyramine, which is required in the L1 stage for learning. This learning signal is transmitted to the AIY memory retrieval neurons by the tyramine receptor SER-2, which is required for imprinted aversion but not for adult learned aversion (Chapter …

Comparative analysis of Anopheles gambiae L-tyrosine decarboxylase and L-DOPA decarboxylase
A major pathway of tyramine and dopamine synthesis in insects is through the decarboxylation of tyrosine and DOPA, respectively. Although tyrosine decarboxylase (TDC) has been mentioned in some reports, it has never been critically analyzed. The high sequence identity shared by tyrosine …

Exploring new chemical entities from traditional medicine: Docking, synthesis and specific bioactivities
… sites of PPARγ (target of rosiglitazone), tyramine derivatives were found to possess good docking scores and binding poses. Henceforth, twenty-four cinnamomyl phenylethyl amide derivatives (termed as tyramine-derivatives) were synthesized and were tested in vitro using PPARγ-PPARα …

Analysis of Biogenic Amines by GC/FID and GC/MS
… (cadaverine), 1000 ppm (histamine), and 350 ppm (tyramine). Good precision of six amine stardards at 50 ppm was shown: heptylamine 5.2%, putrescine 5.6%, cadaverine 5.0%, histamine 9.9%, tyramine 5.1%, and spermidine 6.2% RSD.

Neural Sequences Underlying Directed Turning in C. elegans
… behavior across time. The neuromodulator tyramine coordinates these sequential brain dynamics. Our results illustrate how neuromodulation can act on a defined neural architecture to generate sequential patterns of activity that link sensory cues to motor actions.

Effects of sympathomimetic drugs on the contractility of the vas deferens and on fertility in the male rat and rabbit
… drugs noradrenaline, methoxamine, tyramine and norephedrine, caused rhythmic contractions in isolated human vasa deferentia. These contractions were mediated via α-adrenorcceptors. Intravenous administration of some of these drugs into rats and guinea-pigs produced contractions of …

Neuropeptides Amplify and Focus the Monoaminergic Inhibition of Nociception in <i>Caenorhabditis elegans</i>
… we examined the nutritionally-dependent, tyraminergic inhibition of aversive behavior mediated by the two nociceptive ASH sensory neurons in <i>C. elegans</i>. Tyramine (TA) and octopamine (OA) activate adrenergic-like signaling in invertebrates and are released during starvation. TA is …
