Product Description
(R)-Pantetheine, the R-enantiomer of pantetheine, is a biosynthetic precursor to CoA and also a metabolite in the biosynthesis of secondary metabolites such as carbapenem and pantothenate.
Biological Activity I Assay Protocols (From Reference)
Targets
- (R)-Pantetheine targets pantothenate kinase (PANK), a key enzyme in the coenzyme A (CoA) biosynthesis pathway. It acts as a substrate for PANK, with a Michaelis constant (Km) of 8.5 μM for recombinant human PANK1 [1]
ln Vitro
- In recombinant human PANK1 enzyme assays, (R)-Pantetheine (0.1–100 μM) dose-dependently increased PANK1 activity, reaching maximum activation (180% of basal activity) at 50 μM. This activation was specific to (R)-enantiomer; the (S)-enantiomer showed no significant effect on PANK1 activity even at 100 μM [1]
- In HeLa cells treated with (R)-Pantetheine (10–500 μM) for 24 h, intracellular CoA levels were elevated in a dose-dependent manner. At 200 μM, (R)-Pantetheine increased intracellular CoA concentration by ~45% compared to the untreated control group. No cytotoxicity was observed at concentrations up to 500 μM (assessed via MTT assay) [1]
Enzyme Assay
- For PANK1 activity assay with (R)-Pantetheine: The reaction mixture contained 50 mM Tris-HCl (pH 7.5), 10 mM MgCl₂, 2 mM ATP, 0.1–100 μM (R)-Pantetheine, and 0.5 μg recombinant human PANK1. The mixture was incubated at 37°C for 30 minutes. The reaction was terminated by adding 5% trichloroacetic acid, and the amount of ADP produced (indicator of PANK1 activity) was measured using a colorimetric assay based on pyruvate kinase and lactate dehydrogenase. The absorbance at 340 nm was recorded, and PANK1 activity was calculated by comparing with an ADP standard curve [1]
Cell Assay
- For intracellular CoA level detection in HeLa cells: HeLa cells were seeded in 6-well plates at a density of 2×10⁵ cells/well and cultured overnight. The cells were treated with (R)-Pantetheine (10–500 μM) in serum-free medium for 24 h. After treatment, cells were harvested, washed with phosphate-buffered saline, and lysed in 0.5 M perchloric acid. The lysate was neutralized with 2 M KOH, and the supernatant was collected by centrifugation. Intracellular CoA concentration was measured using an enzyme cycling assay, where CoA-dependent reduction of NAD+ to NADH was monitored by absorbance at 340 nm. CoA levels were quantified using a CoA standard curve [1]
- For HeLa cell viability assay: HeLa cells were seeded in 96-well plates at 5×10³ cells/well. After 24 h of attachment, cells were treated with (R)-Pantetheine (10–500 μM) for 24 h. MTT reagent was added to each well, and the mixture was incubated for 4 h. Formazan crystals were dissolved with dimethyl sulfoxide, and absorbance at 570 nm was measured. Cell viability was expressed as a percentage of the untreated control [1]

Additional Infomation
Pantetheine acid thioethylamine is an amide formed by the condensation of the carboxyl group of Pantetheine acid and the amino group of cysteine. It is a metabolite, found in both humans and mice. It is a thiol belonging to the Pantetheine acid thioethylamine family. Pantetheine acid thioethylamine is present in or produced by Escherichia coli (strains K12 and MG1655). It has been reported to exist in humans, rapeseed, and other organisms with relevant data. It is an intermediate in the coenzyme A synthesis pathway in mammalian livers and certain microorganisms.
- (R)-Pantetheine acid thioethylamine is a naturally occurring thiol compound and an intermediate in the biosynthesis of coenzyme A (CoA), which is crucial for fatty acid metabolism, acetyl transfer, and other central metabolic pathways [1]
- This study evaluated (R)-Pantetheine acid thioethylamine as a precursor for regulating CoA levels: its ability to activate PANK1 and increase intracellular CoA suggests potential applications in metabolic disorders associated with CoA deficiency [1]
- Unlike Pantetheine acid (vitamin B5, another CoA precursor), (R)-Pantetheine acid thioethylamine bypasses the rate-limiting step in CoA synthesis (catalyzed by PANK), making it a more efficient regulator of intracellular CoA levels [1]

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
