Synthesis of N-alkylated octopamine derivatives and their interaction with octopamine receptor BmOAR1.

Journal of pesticide science
A series of N-alkylated octopamine derivatives was synthesized, and the structure-activity relationships of these derivatives with the silkworm Bombyx mori octopamine receptor BmOAR1 were evaluated using a secreted placental alkaline phosphatase reporter assay system.

Co-option of neurotransmitter signaling for inter-organismal communication in C. elegans

Nature Communications, 2019
Inter-organismal signaling is essential for animals to navigate and survive in their natural environment, yet is unclear how these chemical communication channels may have evolved.

RNA Interference of Dual Oxidase in the Plant Nematode Meloidogyne incognita

Molecular Plant-Microbe Interactions, 2005
RNA interference (RNAi) is a powerful tool for the analysis of gene function in model organisms such as the nematode Caenorhabditis elegans. Recent demonstrations of RNAi in plant parasitic nematodes provide a stimulus to explore the potential of using ...

Octopamine and ammonia plasma levels in hepatic encephalopathy

, 1977
It has been recently proposed that hepatic encephalopathy could be due to the accumulation of octopamine acting as a false neurotransmitter, and the increase of ammonia might reflect this accumulation.

Adrenergic Metabolic and Hemodynamic Effects of Octopamine in the Liver

, 2013
The fruit extracts of Citrus aurantium (bitter orange) are traditionally used as weight-loss products and as appetite suppressants. A component of these extracts is octopamine, which is an adrenergic agent.

Synergic effects of tryptamine and octopamine on ophiuroid luminescence (Echinodermata).

, 2004
In ophiuroids, bioluminescence is under nervous control. Previous studies have shown that acetylcholine is the main neurotransmitter triggering light emission in Amphipholis squamata and Amphiura filiformis.

Octopamine integrates the status of internal energy supply into the formation of food-related memories

eLife
The brain regulates food intake in response to internal energy demands and food availability. However, can internal energy storage influence the type of memory that is formed?

Octopamine enhances dark-adaptation in Limulus ventral photoreceptors

, 1985
Limulus ventral photoreceptors receive synaptic input from fibers that emerge from the brain and that appear to use octopamine as a transmitter. Exogenous application of octopamine has been shown to increase levels of intracellular cAMP in ventral ...
