Introduction of 110659-91-1 :

Psammaplin A is a marine metabolite. Psammaplin A is a selective HDAC1 (IC50: 45 nM), DNA methyltransferases (IC50: 18.6 nM) and aminopeptidase N (APN) (IC50: 18 μM) inhibitor. Psammaplin A also inhibits DNA topoisomerase and farnesyl protein transferase. Psammaplin A is a PPARγ activator and induces apoptosis. Psammaplin A has antitumor and anti-inflammatory activities. Psammaplin A has antibacterial activity against Gram-positive bacteria and inhibits DNA synthesis and DNA gyrase activity. Psammaplin A inhibits angiogenesis[1][2][3][4][5][6][7][8]. IC50 & Target:IC50: 0.9 nM (DAC1)[1] In Vitro:Psammaplin A inhibits the viability of A549 (GI50: 7.5 μM), MCF7 (GI50: 1.27 μM), and WI38 (GI50: 3.44 μM) cells[1].
Psammaplin A (72 h) inhibits the viability of A549 (IC50: 1.18 μM) and HCT116 (IC50: 1.62 μM) cells[2].
Psammaplin A (0.5-5 μM) inhibits bFGF-induced angiogenesis in bovine aortic endothelial cells (BAEC) in a dose-dependent manner[3].
Psammaplin A (0-100 μg/mL, 1-4 h) inhibits the toxicity of INT-407 cells induced by V. vulnificus in a concentration- and time-dependent manner[4].
Psammaplin A (0-100 μg/mL, 0-13 h) inhibits the growth of V. vulnificus in a concentration-dependent manner[4].
Psammaplin A (0-40 μM, 12 h) inhibits the viability of the macrophage cell line RAW264.7 in a concentration-dependent manner[6].
Psammaplin A (0-500 μM, 2 h) inhibits SV40 DNA replication in HeLa cells in a concentration-dependent manner. Psammaplin A (125-500 μM, 30 min) inhibits the catalytic activity of topoisomerase I[6].
Psammaplin A (125-500 μM, 15 min) inhibits the binding activity of RPA to single-stranded DNA[6].
Psammaplin A (1-40 μM, 30 min) inhibits the activity of polymerase α-primase in a concentration-dependent manner[6].
Psammaplin A (3-30 μM, 4-16 h) induces apoptosis in T47D and MCF-7 cells[8].
In Vivo:Psammaplin A (30 mg/kg, i.p., three times a week for 35 d) has antitumor activity in mice in the A549 xenograft model[2].
Psammaplin A (5-50 μg, i.p., once) improves the survival rate of mice in the V. vulnificus-infected model[4].
