D-Pantethine has vitamin activity equivalent to d-pantothenic acids for recovering from a deficiency of D-pantothenic acid in rats
J Nutr Sci Vitaminol (Tokyo) 2013;59(2):93-9.23727638 10.3177/jnsv.59.93
D-Pantethine is a compound in which two molecules of D-pantetheine bind through an S-S linkage. D-Pantethine is available from commercial sources as well as from D-pantothenic acid. We investigated if D-Pantethine has the same vitamin activity as D-pantothenic acid by comparing the recovery from a deficiency of D-pantothenic acid in rats. D-Pantothenic acid-deficient rats were developed by weaning rats on a diet lacking D-pantothenic acid for 47 d. At that time, the urinary excretion of D-pantothenic acid was almost zero, and the body weight extremely low, compared with the control (p<0.05); the contents of free D-pantothenic acid were also significantly reduced in comparison with those of controls (p<0.05). D-Pantothenic acid-deficient rats were administered a diet containing D-pantothenic acid or D-Pantethine for 7 d. D-Pantethine and D-pantothenic acid contents of the diets were equimolar in forms of D-pantothenic acid. We compared various parameters concerning nutritional status between rats fed D-pantothenic acid- and D-pantethine-containing diets. The recoveries of body weight, tissue weights, and tissue concentrations of free D-pantothenic acid, dephospho-CoA, CoA, and acetyl-CoA were identical between rats fed diets containing D-pantothenic acid and D-Pantethine. Thus, the biological efficiency for recovering from a deficiency of D-pantothenic acid in rats was equivalent between D-pantothenic acid and D-Pantethine.
Antioxidants selenomethionine and D-Pantethine decrease the negative side effects of doxorubicin in NL/Ly lymphoma-bearing mice
Croat Med J 2016 Apr 23;57(2):180-92.27106359 PMC4856192
Aim: To investigate the potential tissue-protective effects of antioxidants selenomethionine and D-Pantethine applied together with doxorubicin (Dx) on NK/Ly lymphoma-bearing mice. The impact of this chemotherapy scheme on animal survival, blood cell profile, hepatotoxicity, glutathione level, and activity of glutathione-converting enzymes in the liver was compared with the action of Dx applied alone.. Methods: The hematological profile of animals was studied by the analysis of blood smears under light microscopy. Hepatotoxicity of studied drugs was evaluated measuring the activity of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) enzymes, De Ritis ratio, and coenzyme A fractions by McDougal assay. Glutathione level in animal tissues was measured with Ellman reagent, and the activity of glutathione reductase, transferase, and peroxidase was measured using standard biochemical assays. Results: D-Pantethine (500 mg/kg) and, to a lower extent, selenomethionine (600 µg/kg) partially reduced the negative side effects (leukocytopenia and erythropenia) of Dx (5 mg/kg) in NK/Ly lymphoma bearing animals on the 14th day of their treatment. This increased animal survival time from 47-48 to 60+ days and improved the quality of their life. This ability of D-Pantethine and selenomethionine was realized via hepatoprotective and immunomodulating activities. D-Pantethine also restored the levels of acid-soluble and free CoA in the liver of tumor-bearing animals, while selenomethionine caused the recovery of glutathione peroxidase levels in the liver, which was significantly diminished under Dx treatment. Both compounds decreased glutathione level in the liver, which was considerably induced by Dx. Conclusions: Antioxidants selenomethionine and D-Pantethine partially reversed the negative side effects of Dx in NK/Ly lymphoma-bearing mice and significantly increased the therapeutic efficiency of this drug in tumor treatment.
Metabolism of Pantethine in cystinosis
J Clin Invest 1985 Oct;76(4):1665-72.4056044 PMC424158
D-Pantethine is a conjugate of the vitamin pantothenic acid and the low-molecular-weight aminothiol cysteamine. Pantethine is an experimental hypolipemic agent and has been suggested as a source of cysteamine in the treatment of nephropathic cystinosis. We treated four cystinotic children with 70-1,000 mg/kg per d oral D-Pantethine and studied its metabolism. Pantethine was rapidly hydrolyzed to pantothenic acid and cysteamine; we could not detect Pantethine in plasma after oral administration. The responsible enzyme, "pantetheinase," was highly active in homogenates of small intestinal mucosa and plasma. The Michaelis constant of the rat intestinal enzyme was 4.6 microM and its pH profile showed a broad plateau between 4 and 9. Pantothenate pharmacokinetics after orally administered Pantethine followed an open two-compartment model with slow vitamin elimination (t1/2 = 28 h). Peak plasma pantothenate occurred at 2.5 h and levels over 250 microM were seen at 300 times normal. Apparent total body storage of pantothenate was significant (25 mg/kg), and plasma levels were elevated threefold for months after Pantethine therapy. Plasma cysteamine concentrations after Pantethine were similar to those reported after equivalent doses of cysteamine. However, at best only 80% white blood cell cystine depletion occurred. We conclude that Pantethine is probably less effective than cysteamine in the treatment of nephropathic cystinosis and should only be considered in cases of cysteamine intolerance. Serum cholesterol was decreased an average of 14%, which supports the potential clinical significance of Pantethine as a hypolipemic agent. Rapid in vivo hydrolysis of Pantethine suggests that pantothenate or cysteamine may be the effectors of its hypolipemic action.
The effect of Pantethine and ultraviolet-B radiation on the development of lenticular opacity in the emory mouse
Curr Eye Res 2000 Jan;20(1):17-24.10611711
Purpose: Few studies have examined the impact of long-term treatments or exposures on the development of cataract in maturity-onset animal models. We studied the effect of treatment with D-Pantethine and exposure to ultraviolet-B (UVB) radiation on the development of lenticular opacity in the Emory mouse. Methods: A total of 164 Emory mice were randomized by litter at weaning to exposure to UVB light at 12 mJ/cm(2) for 6 hr/day (UV) or usual room light (A), and within litter, were further randomized to bi-weekly intra-peritoneal injections of 0.8 g/kg Pantethine (T) or no treatment (C). Retro illumination lens photos were taken at 2, 4, 6, 8, and 10 months after weaning, and graded in masked fashion. The animals were sacrificed at 10 months and the lenses analyzed for total Pantethine and total cysteamine. Results: Lens Pantethine and cysteamine levels were significantly (P < 0.001) higher for the T as compared to C litters. Mean cataract grade increased monotonically over time for all four groups. Unadjusted mean grade for the AT group at 8 (1.32) and 10 (1.86) months appeared lower than for the other groups (AC: 2.17, 2.39; UVC: 1.77, 2.40; UVT: 1.88, 2.37). However, the mean grade for the pantethine-treated litters did not differ significantly from the untreated litters except at 2 months (when untreated litters had significantly lower grades), when adjusting for UV treatment, gender and litter effect. No significant difference in cataract score existed between UV-exposed and ambient litters. Mortality was higher among pantethine-treated (hazard ratio = 1.8, p = 0.05) and UV-exposed animals (hazard ratio = 1.8, p = 0. 03) than among the untreated and unexposed litters. Conclusion: Significantly increased lens levels of Pantethine are achieved with long-term intra-peritoneal dosing. The impact of Pantethine on the progression of lenticular opacity in the Emory mouse is less than has been reported in other models. This level of chronic UVB exposure appeared to have no effect on the development of cataract in this model.
Tissue-protective activity of selenomethionine and D-panthetine in B16 melanoma-bearing mice under doxorubicin treatment is not connected with their ROS scavenging potential
Croat Med J 2017 Apr 14;58(2):171-184.28409500 PMC5410729
Aim: To evaluate molecular mechanisms of tissue-protective effects of antioxidants selenomethionine (SeMet) and D-Pantethine (D-Pt) applied in combination with doxorubicin (Dx) in B16 melanoma-bearing-mice. Methods: Impact of the chemotherapy scheme on a survival of tumor-bearing animals, general nephro- and hepatotoxicity, blood cell profile in vivo, and ROS content in B16 melanoma cells in vitro was compared with the action of Dx applied alone. Nephrotoxicity of the drugs was evaluated by measuring creatinine indicator assay, hepatotoxicity was studied by measuring the activity of ALT/AST enzymes, and myelotoxicity was assessed by light microscopic analysis of blood smears. Changes in ROS content in B16 melanoma cells under Dx, SeMet, and D-Pt action in vitro were measured by incubation with fluorescent dyes dihydrodichlorofluoresceindiacetate (DCFDA, H2O2-specific) and dihydroethidium (DHE, O2--specific), and further analysis at FL1 (DCFDA) or FL2 channels (DHE) of FACScan flow cytometer. The impact of aforementioned compounds on functional status of mitochondria was measured by Rhodamine 123 assay and further analysis at FL1 channel of FACScan flow cytometer. Results: Selenomethionine (1200 µg/kg) and D-Pantethine (500 mg/kg) in combination with Dx (10 mg/kg) significantly reduced tumor-induced neutrophilia, lymphocytopenia, and leukocytosis in comparison to Dx treatment alone. Moreover, SeMet and D-Pt decreased several side effects of Dx, namely an elevated creatinine level in blood and monocytosis, thus normalizing health conditions of B16 melanoma-bearing animals. Conclusions: Our results showed that antioxidants selenomethionine and D-Pantethine possess significant nephroprotective and myeloprotective activity toward Dx action on murine B16 melanoma in vivo, but fail to boost a survival of B16 melanoma-bearing animals. The observed cytoprotective effects of studied antioxidants are not directly connected with their ROS scavenging.
