Biological Activity
| Targets | Hydrolysis product of Fumonisin B1 |
| ln Vitro | Fumonisin B1 (FB1) is the predominant member of a family of mycotoxins produced by Fusarium moniliforme (Sheldon) and related fungi. Certain foods also contain the aminopentol backbone (AP1) that is formed upon base hydrolysis of the ester-linked tricarballylic acids of FB1. Both FB1 and, to a lesser extent, AP1 inhibit ceramide synthase due to structural similarities between fumonisins (as 1-deoxy-analogs of sphinganine) and sphingoid bases. To explore these structure-function relationships further, erythro- and threo-2-amino, 3-hydroxy- (and 3, 5-dihydroxy-) octadecanes were prepared by highly stereoselective syntheses. All of these analogs inhibit the acylation of sphingoid bases by ceramide synthase, and are themselves acylated with Vmax/Km of 40-125 for the erythro-isomers (compared with approximately 250 for D-erythro-sphinganine) and 4-6 for the threo-isomers. Ceramide synthase also acylates AP1 (but not FB1, under the conditions tested) to N-palmitoyl-AP1 (PAP1) with a Vmax/Km of approximately 1. The toxicity of PAP1 was evaluated using HT29 cells, a human colonic cell line. PAP1 was at least 10 times more toxic than FB1 or AP1 and caused sphinganine accumulation as an inhibitor of ceramide synthase. These studies demonstrate that: the 1-hydroxyl group is not required for sphingoid bases to be acylated; both erythro- and threo-isomers are acylated with the highest apparent Vmax/Km for the erythro-analogs; and AP1 is acylated to PAP1, a new category of ceramide synthase inhibitor as well as a toxic metabolite that may play a role in the diseases caused by fumonisins [2]. |

| Additional Infomation |
(2S,3S,5R,10R,12S,14S,15R,16R)-2-amino-12,16-dimethylicosane-3,5,10,14,15-pentol is a pentol that is (3S,5R,10R,12S,14S,15R,16R)-12,16-dimethylicosane-3,5,10,14,15-pentol in which the pro-S hydrogen at position 2 is substituted by an amino group. It results from hydrolysis of the O-acyl bonds of fumonisin B1. It is a pentol and a primary amino compound. It is a conjugate base of a (2S,3S,5R,10R,12S,14S,15R,16R)-2-amino-12,16-dimethylicosane-3,5,10,14,15-pentol(1+). Aminopentol (AP1), the backbone and main hydrolysis product of the mycotoxin fumonisin B1 (FB1), is present in corn-based foods which are consumed daily as a substantial part of the diet in some areas of the world. The toxicity of FB1 has been attributed to altered sphingolipid metabolism, but the toxicity of AP1 is less certain. Epidemiological correlations and in vitro studies have suggested that AP1 can increase neural tube defects (NTDs), but no in vivo developmental study of AP1 was done prior to this study. AP1 was given once daily to rats by gavage on gestation days (GD) 3-16 at doses of 0, 15, 30, 60, or 120 mg/kg. Reproductive and developmental parameters were measured at GD 17, one day after the last dose, and on GD 20. In addition, on GD 17, maternal and fetal tissues were analyzed for sphingolipid content. Conclusions: AP1 reduced dam body weight gain, but was less toxic than FB1. AP1 was not teratogenic, did not affect tissue sphingolipid ratios, did not alter reproduction or development of fetuses, and produced no dose-related histopathological effects in dams. [1] Fumonisin B1 (FB1) and aminopentol (AP1) (which is formed by hydrolysis of FB1) are found in corn contaminated with some strains of Fusarium moniliforme. Incubation of HT29 cells (a human colonic cell line) with FB1 or AP1 caused a significant reduction in cell number; AP1 was less potent, with 50 microM AP1 causing the same reduction (ca. 30% after 24 h) as 10 microM FB1. The reduction in cell number reflected increases in DNA fragmentation and the percentage of apoptotic cells. Both FB1 and AP1 caused the accumulation of sphinganine (25- and 35-fold by 10 microM FB1 and 50 microM AP1, respectively); thus, concentrations of FB1 and AP1 that caused comparable reductions in cell number were also similar with respect to elevation of sphinganine, a compound that is growth inhibitory and cytotoxic. Inhibition of the first step of sphingolipid biosynthesis with ISP-1 prevented the elevation in sphinganine, DNA fragmentation, and apoptosis induced by FB1. Therefore, these effects of FB1 on HT29 cells can be attributed to the accumulation of sphinganine. Since consumption of food contaminated with Fusarium moniliforme (Sheldon) exposes colonic cells to these mycotoxins, the possibility that FB1 and AP1 are toxic for intestinal cells in vivo should be evaluated, especially in the light of the recent report (Bhat et al., Clin. Toxicol. 35, 249, 1997) describing intestinal disturbances in humans after consumption of moldy corn and sorghum containing fumonisins. [3] |
