Cyclic adenosine diphosphate-ribose
Cyclic adenosine diphosphate-ribose (cADPR), CAS 119340-53-3, with the molecular formula C15H21N5O13P2, is a key intracellular second messenger. It plays a vital role in regulating intracellular calcium release via ryanodine receptors. This compound is crucial for processes such as glucose-induced insulin release in the pancreas and abscisic acid-mediated calcium signalling in plants. Supplied by Tech Serve Solutions as a lyophilised powder.

Intracellular Calcium Signalling
cADPR mobilises intracellular Ca2+ from storage sites like the sarcoplasmic reticulum, primarily by activating ryanodine receptors. This mechanism is fundamental to numerous cellular processes.
Endocrine Pancreas Function
It acts as a second messenger in the regulation of glucose-stimulated insulin secretion from pancreatic endocrine cells, contributing to glucose homeostasis.
Plant Physiology
In plants, cADPR is involved in signalling pathways, notably mediating calcium release in response to plant hormones such as abscisic acid.
Neuroscience Research
As a cell signalling molecule influencing calcium dynamics, cADPR has relevance in understanding neuronal function and neurological processes.
