Cyclic ADP-ribose (cADPR) is an effective calcium mobilization second messenger, which is synthesized from NAD + by ADP-ribosyl cyclase. Cyclic ADP-ribose mainly increases cytosolic calcium through Ryanodine receptor-mediated endoplasmic reticulum release

Sulfatides are endogenous sulfoglycolipids with various biological activities in the central and peripheral nervous systems, pancreas, and immune system. They are produced from the combination of ceramide and UDP-galactose in the endoplasmic reticulum followed by sulfation in the Golgi apparatus. The ceramide portion contains variable fatty acid chain lengths, which are tissue- and pathology-dependent. Sulfatides are primarily found in the myelin sheath of oligodendrocytes and Schwann cells, with smaller chain lengths predominant during development and longer chain lengths predominant in mature cells. They accumulate in the lysosome of patients with metachromatic leukodystrophy, a disorder characterized by arylsulfatase A deficiency. Sulfatides are also located in pancreatic β-cells and inhibit insulin release from isolated rat pancreatic islet cells, suggesting a potential role in diabetes. Sulfatides can induce inflammation in glia in vitro and certain sulfatides, such as C24:1 3'-sulfo-galactosylceramide, can induce an immune response in vitro in mouse splenocytes. Sulfatides (bovine) (sodium salt) is a mixture of isolated bovine sulfatides.
Cyclic ADP-ribose ammonium (cADPR ammonium) is a powerful calcium mobilization second messenger synthesized from NAD+ by an ADP-ribosyl cyclase. It primarily raises cytosolic calcium levels through Ryanodine receptor-mediated release from the endoplasmic reticulum, while also facilitating extracellular influx through the opening of TRPM2 channels [1][2][3].
β-D-Glucopyranosyl abscisate (ABA-GE) is a hydrolyzable conjugate of abscisic acid (ABA), which predominantly accumulates in the vacuole and likely in the endoplasmic reticulum. The deconjugation of β-D-Glucopyranosyl abscisate enables a swift release of free ABA in response to abiotic stress factors like dehydration and salt stress. β-D-Glucopyranosyl abscisate plays a crucial role in maintaining ABA homeostasis.
