Aristoforin
Aristoforin, a hypericin derivative, inhibits the activities of SIRT1 and SIRT2. Aristoforin induces G1 phase cell cycle arrest, scavenges hydroxyl free radicals, and exhibits protective activity against Fe2+-induced DNA breakage. Aristoforin can be used in studies related to breast cancer and colon adenocarcinoma.

In Vitro
Aristoforin (24 h) potently inhibits primary human umbilical vein endothelial cell proliferation with a mean IC50 of 3.14 μM[1].
Aristoforin (24 h) potently inhibits primary human dermal lymphatic endothelial cell proliferation with a mean IC50 of 2.54 μM, and completely blocks proliferation at 5 μM[1].
Aristoforin (24 h) potently inhibits primary human lung lymphatic endothelial cell proliferation with a mean IC50 of 2.63 μM[1].
Aristoforin (10-50 μM; 24 h) induces dose-dependent apoptosis in primary human dermal lymphatic endothelial cells, with significant effects observed at concentrations of 10 μM and above, and exhibits greater proapoptotic potency than hyperforin[1].
Aristoforin (5-30 μM; 48 h) induces G1 phase cell cycle arrest in primary human dermal lymphatic endothelial cells at 5 μM, and induces apoptosis (evidenced by increased sub-G1 cells) at 30 μM[1].
Aristoforin (30 μM; 48 h) activates the intrinsic apoptosis pathway in primary human dermal lymphatic endothelial cells at 30 μM, as shown by activation of caspase-3 and caspase-9 without caspase-8 activation[1].
Aristoforin (20 μM; 20 min at 37°C) induces a rapid loss of mitochondrial membrane potential in primary human dermal lymphatic endothelial cells[1].
Aristoforin (1-5 μM; 16 h) alters MRP1, MRP2, BCRP, and P-gp protein levels in human colon adenocarcinoma HT-29 cells in a time- and light-dependent manner, including decreased MRP2 at T0- and T6+, increased MRP1 at T0-, and increased P-gp at T6+ and T6-[2].
Aristoforin (1-5 μM; 16 h) alters CYP3A4 protein levels in human colon adenocarcinoma HT-29 cells in vitro in a concentration-, time-, and light-dependent manner, including increased levels at T0-, T6-, and T6+ (1 μM), and decreased levels at T0+ (5 μM)[2].
Aristoforin (1-5 μM; 16 h) induces BCRP mRNA expression at T0- in human colon adenocarcinoma HT-29 cells[2].
Aristoforin (1-5 μM; 16 h) modulates CYP3A4 mRNA expression in human colon adenocarcinoma HT-29 cells in vitro in a concentration-, time-, and light-dependent manner, including induction at T0+ (1 μM) and T6+ (5 μM), and reduction at T6-[2].
Aristoforin (5-10 μM; 30 min) significantly decreases BCRP activity in human colon adenocarcinoma HT-29 cells, with no significant effect on MRP1 or MRP2 activity[2].
Aristoforin (10 μM; 16 h) significantly decreases CYP3A4 activity in both human colon adenocarcinoma HT-29 cells and Oxaliplatin (HY-17371)-resistant HT-29-OxR cells, independent of light activation[2].
Aristoforin (0.01-10 mM; 25 min) exhibits concentration-dependent DPPH radical scavenging activity, with 5.76%, 12.03%, 17.89%, and 28.02% scavenging at 0.01, 0.1, 1, and 10 mM respectively[3].
Aristoforin (0.01-10 mM; 20 min at 50°C) exhibits very low reducing power, with absorbance values of 0.002, 0.002, 0.068, and 0.085 at 0.01, 0.1, 1, and 10 mM respectively[3].
Aristoforin (0.01-10 mM; 10 min) does not chelate ferrous ions at concentrations ranging from 0.01 to 10 mM[3].
Aristoforin (0.01-1 mM; 90 min at 25°C) exhibits concentration-dependent hydroxyl radical scavenging activity, with 18.18 ± 6.54%, 33.0 ± 2.75%, and 55.84 ± 8.21% scavenging at 0.01, 0.1, and 1 mM respectively[3].
Aristoforin (1-5 μM) at 5 μM, when used as a 16 h pre-incubation followed by 50 nM Hypericin (HY-N0453)-mediated PDT, significantly enhances apoptosis in HT-29 colon adenocarcinoma cells[4].
Aristoforin (1-5 μM) at 5 μM, when used as a 16 h pre-incubation followed by 50 nM Hypericin-mediated PDT, normalizes the cell cycle distribution of HT-29 colon adenocarcinoma cells at 24 h post-PDT, counteracting the S-phase accumulation induced by PDT alone[4].
Aristoforin (1-5 μM) at 5 μM, when used as a 16 h pre-incubation followed by 50 nM hypericin-mediated PDT, significantly suppresses MMP2 and MMP9 expression in HT-29 colon adenocarcinoma cells at 6 h post-PDT[4].
Aristoforin (1-5 μM) at 5 μM, when used as a 16 h pre-incubation followed by 50 nM hypericin-mediated PDT, drastically reduces cellular adhesivity of HT-29 colon adenocarcinoma cells[4].
Aristoforin (1-5 μM) at 5 μM, when used as a 16 h pre-incubation followed by 50 nM hypericin-mediated PDT, potently suppresses clonogenic survival of HT-29 colon adenocarcinoma cells[4].
