Aurothiomalate disodium
Aurothiomalate disodium acts as an inhibitor of PKCI and TrxR1. Aurothiomalate disodium disrupts the PKCI-Par6-Rac1 signaling pathway, and also inhibits TrxR1 activity, TNFα-induced NF-κB activation, and the expression of pro-inflammatory genes. Aurothiomalate disodium blocks Kras-mediated BASC expansion and lung tumor growth, inhibits anchorage-independent growth and tumorigenicity of lung cancer cells, and suppresses neutrophil chemotaxis, phagocytosis, and leukocyte extravasation. Aurothiomalate disodium can be used in research related to rheumatoid arthritis and non-small cell lung cancer.

Biological Activity
|
PKCι |
Aurothiomalate (20 μmol/L; in vitro culture duration) disodium blocks the proliferative expansion and morphological transformation of bronchoalveolar stem cells isolated from LSL-Kras mice that are mediated by oncogenic Kras in vitro[2].
Aurothiomalate disodium potently inhibits the activity of mouse liver thioredoxin reductase in vitro[3].
Aurothiomalate (25-50 μM; administered 48 h prior to 6 h TNFα stimulation) disodium inhibits TNFα-induced NF-κB-dependent gene expression in TrxR1-overexpressing COS7 cells in a dose-dependent manner[3].
Aurothiomalate (50 μM; administered 48 h prior to TNFα stimulation) disodium inhibits TNFα-induced NF-κB DNA-binding activity in TrxR1-overexpressing COS7 cells[3].
Aurothiomalate (25 μM; administered concurrently with TNFα stimulation for 6 h) disodium inhibits TNFα-induced expression of the NF-κB-targeted pro-inflammatory genes E-selectin and COX-2 in bovine arterial endothelial cells[3].

Cell Line:Bovine arterial endothelial cells (BAEC)
-
Concentration:25 uM
-
Incubation Time:6 hours
-
Result:Suppressed TNFa-induced NF-kB-dependent gene expression in a dose-dependent manner.
Did not affect TrxR1 mRNA level in COS7 cells.
Aurothiomalate (0.7 μg/g body weight; administered via intravenous injection, intramuscular injection, or direct air pouch injection; dosed twice) disodium significantly reduces the leukocyte count in exudate in carrageenan-induced acute inflammation models in mice, with intravenous injection exerting the strongest inhibitory effect[4].
Aurothiomalate (0.7 μg/g body weight; tail vein injection; single administration) disodium significantly reduces the leukocyte count in exudate in a carrageenan-induced acute inflammation mouse model[4].
Aurothiomalate (0.7 μg/g body weight; intravenous injection, intramuscular injection, direct air pouch injection) disodium significantly inhibits phagocytosis and chemotaxis of neutrophils in carrageenan-induced acute inflammation in mice, with intravenous and intramuscular injections exerting stronger inhibitory effects on chemotaxis than direct air pouch injection[4].
Aurothiomalate (2-60 mg/kg; intramuscular injection; daily administration) disodium exerts potent antitumor activity against A427 lung cancer xenografts by inhibiting cell proliferation and the Mek/Erk signaling pathway[6].
Aurothiomalate (20-60 mg/kg; intramuscular injection; daily) disodium exhibits moderate antitumor activity against H460 lung cancer xenografts by inhibiting cell proliferation and the Mek/Erk signaling pathway[6].

Animal Model:Athymic nude mice (Harlan Sprague-Dawley, female, 4-6 weeks old, subcutaneous xenograft model via injection of human H460 lung cancer cells)[6]
-
Dosage:20 mg/kg; 60 mg/kg
-
Administration:i.m.; daily
-
Result:Caused a statistically significant ~50% reduction in H460 tumor volume compared to controls at the 60 mg/kg dose.
Reduced BrdUrd-positive nuclei (proliferative index) from ~21% in controls to ~11% at the 60 mg/kg dose.
Reduced the ratio of phospho-Erk 1,2 to total Erk 1,2 compared to controls at the 60 mg/kg dose.
Did not significantly increase the apoptotic index (TUNEL-positive cells remained <1%) or alter tumor vascularization (PECAM1 staining/expression unchanged) at either dose.

Animal Model:Athymic nude mice (Harlan Sprague-Dawley, female, 4-6 weeks old, subcutaneous xenograft model via injection of human A427 lung cancer cells)[6]
-
Dosage:2 mg/kg; 6 mg/kg; 20 mg/kg; 60 mg/kg
-
Administration:i.m.; daily
-
Result:Caused statistically significant inhibition of A427 tumor growth, with final tumor volume far lower than control tumors.
Reduced BrdUrd-positive nuclei (proliferative index) from ~17% in controls to ~9% at 2 mg/kg, ~6% at 6 mg/kg, ~5% at 20 mg/kg, and ~9% at 60 mg/kg.
Reduced the ratio of phospho-Erk 1,2 to total Erk 1,2 compared to controls.
Did not significantly increase the apoptotic index (TUNEL-positive cells remained <1%) or alter tumor vascularization (PECAM1 staining/expression unchanged) at any dose.
-
Animal Model:KrasLA2 (3-week-old; spontaneous activation of latent oncogenic KrasG12D allele via somatic recombination)[2]
-
Dosage:60 mg/kg
-
Administration:i.p.; daily; 3 weeks; 6 weeks
-
Result:Blocked the significant increase in BASCs per terminal bronchiole seen in saline-treated KrasLA2 mice, with BASC number and distribution matching levels in nontransgenic mice.
Reduced lung tumor growth, with a mean fold-change in average tumor size of ~1.6, compared to ~2.5 in saline-treated mice.
