(S)-DMAPT  (Synonyms: (S)-Dimethylamino Parthenolide)

(S)-DMAPT (Dimethylamino Parthenolide), an analogue of Parthenolide (PTL), is an oral active NF-κB inhibitor, with a LD₅₀ of 1.7 μM for cell population in AML cells. Has potential anti-cancer and anti-metastatic effect^[1].

DMAPT treatment decreased constitutive NF-κB binding activity, inhibits cell proliferation and viability of PC-3 and DU145 cells^[2].
Treatment of PC-3 and DU145 cells with 5 and 4 μM DMAPT, respectively, increases the population doubling times of PC-3 prostate cancer cells from 23.0 ± 5.0 h to 42.0 ± 3.0 h and of the DU145 cells from 20.4 ± 2.2 h to 72.5 ± 24.8 h^[2].

Treatment with DMAPT (100 mg/kg, Oral gavage daily for 7 days) increases sensitivity of PC-3 tumor xenografts to X-rays^[2].
DMAPT (100 mg/kg, Oral gavage thrice weekly from 42 to 300 days since birth) treatment slows normal tumor development in TRAMP mice, extending the time-to-palpable prostate tumor by 20%^[3].
DMAPT further reduces the metastatic area below that of the water vehicle treatment group in lung tissues (0.10% ± 0.15 SD, 92% reduction, p = 0.0028) in TRAMP mice^[3].
