Background on Pyrrolidinedithiocarbamate ammonium

Pyrrolidinedithiocarbamate ammonium is a selective NF-κB inhibitor.

In Vitro:Pretreatment of cells with pyrrolidinedithiocarbamate (3-1000 μM) dose-dependently attenuate IL-8 production. Furthermore, pyrrolidinedithiocarbamate (100 μM) suppresses the accumulation of IL-8 mRNA. Pyrrolidinedithiocarbamate inhibits the activation of NF-κB, because pyrrolidinedithiocarbamate suppresses both NF-κB DNA binding and NF-κB-dependent transcriptional activity. NF-κB inhibition with pyrrolidinedithiocarbamate decrease IL-8 production by intestinal epithelial cells[1].

In Vivo:The DSS+pyrrolidinedithiocarbamate ammonium-treated groupII exhibits suppression of shortening of intestinal length and reduction of DAI score. Activated NF-κB level and IL-1β and TNF-α levels are significantly lower in DSS+pyrrolidinedithiocarbamate ammonium-treated groupII. These findings suggest that suppression of NF-κB activity by pyrrolidinedithiocarbamate ammonium can delay the healing of mucosal tissue defects (erosions or ulcers) arising from inflammation, but that it can strongly suppress the expression of inf-lammatory cytokines (IL-1β and TNF-α), resulting in significant alleviation of colitis. pyrrolidinedithiocarbamate ammonium is useful for the treatment of ulcerative colitis[2].

Differential determination of tellurium(IV) and tellurium(VI) with sodium diethyldithiocarbamate, ammonium pyrrolidinedithiocarbamate and dithizone by atomic-absorption spectrophotometry with a carbon-tube atomizer.[Pubmed:18962446]

Talanta. 1979 May;26(5):337-40.

The extraction behaviour of tellurium(IV) and tellurium(VI) with sodium diethyldithiocarbamate, ammonium pyrrolidinedithiocarbamate and dithizone in organic solvents has been investigated by means of flameless atomic-absorption spectrophotometry with a carbon-tube atomizer. The selective extraction of tellurium(IV) and differential determination of tellurium(IV) and tellurium(VI) have been developed. With sodium diethyldithiocarbamate and carbon tetrachloride, when the aqueous phase/organic solvent volume-ratio is 5 and the injection volume in the carbon tube is 20 microl, the sensitivity for tellurium is 0.3 ng/ml for 1% absorption. The relative standard deviations are ca. 2%. The proposed methods have been applied satisfactorily to determination of tellurium(IV) and tellurium(VI) in various types of water.

Neutron activation analysis of normal and cadmium injected rat liver using ammonium pyrrolidinedithiocarbamate extraction.[Pubmed:7208991]

Radioisotopes. 1980 Aug;29(8):368-72.

A radiochemical group separation using APDC extraction was applied to the neutron activation analysis of normal and cadmium injected rat liver. In order to optimize determinations of induced radionuclides with various half lives, the gamma-ray spectra were obtained after various decay times. Eight elements, Cd, Co, Cu, Fe, Mn, Mo, Se and Zn, were determined from rat liver samples within 12 day after irradiation. Although Cd, Cu and Mo in normal rat liver could not be detected by nondestructive method, they could be determined after the extraction. The tendency was seen that the concentration of all the elements as mentioned above are increased by cadmium injection. In particular, zinc and copper exhibited high values.

Determination of tin by resin-suspension electrothermal atomic absorption spectrometry after enrichment as the complex with ammonium pyrrolidinedithiocarbamate.[Pubmed:18071232]

Anal Sci. 2007 Dec;23(12):1435-8.

A resin-phase extraction method has been optimized for the trace determination of tin(II) by ETAAS. Tin(II) was extracted on a finely divided anion exchange resin as the complex with ammonium pyrrolidinedithiocarbamate (APDC). The resin was collected on a membrane filter and then dispersed in 1.00 ml of 1 mol l(-1) nitric acid containing 100 microg of Pd(II) and 60 microg of Ni(II). The resulting resin suspension was subjected to GFAAS. The proposed method was applied to the determination of tin(II) in hydrochloric acid.

Collection of trace heavy metals complexed with ammonium pyrrolidinedithiocarbamate on surfactant-coated alumina sorbents.[Pubmed:18966739]

Talanta. 1997 Feb;44(2):231-7.

Surfactant aggregates were formed on alumina surfaces by mixing 100 mg of sodium dodecyl sulfate (SDS) and 1.5 g of gamma-alumina in 50 ml of water. The SDS-coated alumina incorporated water-insoluble metal-ammonium pyrrolidinedithiocarbamate complexes over the pH range 2-8 with a recovery of > 97%. The metals were quantitatively desorbed from the alumina with 4 mol 1(-1) nitric acid, leaving > 99% of SDS on the solid phase. They were determined by inductively coupled plasma mass spectrometry or graphite furnace atomic absorption spectrometry. The proposed method was successfully applied to the determination of traces of iron, cobalt, nickel, copper, cadmium and lead in high-purity alumina.

Pyrrolidine dithiocarbamate, a potent inhibitor of nuclear factor kappa B (NF-kappa B) activation, prevents apoptosis in human promyelocytic leukemia HL-60 cells and thymocytes.[Pubmed:7986199]

Biochem Pharmacol. 1994 Nov 16;48(10):1883-9.

We examined the effect of pyrrolidine dithiocarbamate (PDTC), which potently blocks the activation of nuclear factor kappa B (NF-kappa B), on the induction of apoptosis by a variety of agents. Treatment of a human promyelocytic leukemia cell line, HL-60, with 10 micrograms/mL etoposide or 2 microM 1-beta-D-arabinofuranosylcytosine induced NF-kappa B activation within 1 hr and subsequently caused apoptosis within 3-4 hr. The simultaneous addition of 50-500 microM PDTC with these agents blocked NF-kappa B activation and completely abrogated both morphologically apoptotic changes and internucleosomal DNA fragmentation for up to 6 hr. However, PDTC failed to inhibit the endonuclease activity contained in the whole cell lysates. The inhibitory effect of PDTC was also observed in etoposide- and dexamethasone-induced apoptosis in human thymocytes at a concentration of 1-10 microM. Since PDTC has both antioxidant and metal-ion chelating activities, we tested the effects of N-acetyl-L-cysteine (NAC) (antioxidant) or o-phenanthroline (OP) (metal-ion chelator) on the induction of apoptosis. Pretreatment of HL-60 cells or thymocytes with 100-500 microM OP for 2 hr, but not 10-60 mM NAC, suppressed subsequent occurrence of apoptosis induced by etoposide. These results suggest that the activation of NF-kappa B plays an important role in the apoptotic process of human hematopoietic cells.

Pyrrolidine dithiocarbamate differentially affects interleukin 1 beta- and cAMP-induced nitric oxide synthase expression in rat renal mesangial cells.[Pubmed:7513157]

Biochem Biophys Res Commun. 1994 Apr 15;200(1):163-70.

Inducible nitric oxide synthase (NOS) is expressed in renal mesangial cells in response to two principal classes of activating signals that interact in a synergistic fashion. These two groups of activators comprise inflammatory cytokines such as interleukin 1 (IL-1) or tumour necrosis factor alpha and agents that elevate cellular levels of cAMP. We have used pyrrolidine dithiocarbamate (PDTC), a potent inhibitor of nuclear factor kappa B (NF kappa B), to determine its role in IL-1 beta- and cAMP-triggered NOS expression. Micromolar amounts of PDTC suppress IL-1 beta-, but not cAMP-stimulated nitrite production, the stable end product of NO formation in mesangial cells. Furthermore, PDTC completely inhibited the increase of NOS mRNA in response to IL-1 beta, while only marginally affecting cAMP-induced NOS mRNA levels. Our data suggest that NF kappa B activation is an essential component of the IL-1 beta signalling pathway responsible for NOS gene activation and that cAMP triggers a separate signalling cascade not involving NF kappa B. These observations may provide a basis for the synergistic stimulation of NOS expression by cytokines and cAMP in mesangial cells.

Pyrrolidine dithiocarbamate selectively prevents the expression of the inducible nitric oxide synthase in the rat aorta.[Pubmed:7533726]

Eur J Pharmacol. 1994 Nov 14;265(1-2):83-7.

Exposure of rat aortic rings without endothelium to interleukin-1 beta for 5 h significantly attenuated the contractions due to phenylephrine and increased the tissue content of guanosine 3',5'-cyclic monophosphate (cyclic GMP) due to the induction of nitric oxide synthase. The presence of pyrrolidine dithiocarbamate, a specific inhibitor of nuclear transcription factor kappa B activation, during the exposure of the rings to interleukin-1 beta prevented these responses to interleukin-1 beta. Rat aortic rings which had been incubated for 5 h with interleukin-1 beta in the absence and presence of pyrrolidine dithiocarbamate prior to the organ chamber experiment had a similar concentration-dependent relaxation curve for acetylcholine in rings with endothelium, and for 3-morpholino-sydnonimine (SIN-1) in rings without. Pyrrolidine dithiocarbamate applied acutely did not alter the tone elicited by phenylephrine in rings with or without endothelium and had no effect on the subsequent relaxation induced by acetylcholine in rings with endothelium or by SIN-1 in rings without endothelium. These observations suggest that pyrrolidine dithiocarbamate prevents the interleukin-1 beta-mediated expression of the inducible nitric oxide synthase without affecting the activity of the constitutive enzyme in the rat aorta.
