• 产品描述： AT101, the R-(-) enantiomer of Gossypol acetic acid, binds with Bcl-2, Bcl-xL and Mcl-1 with Ki of 0.32 μM, 0.48 μM and 0.18 μM; does not inhibit BIR3 domain and BID. Phase 2.

• 靶点： Autophagy;BCL

• 体内研究：
  AT-101 is still detectable in plasma with average concentrations of 0.49 μM for the 35 mg/kg group and 0.39 μM for the 200 mg/kg group in SCID beige mice bearing RL-DLBCL xenograft. AT-101 peak plasma concentration is observed after 30 minutes of administration of the drug in both the dose levels, with the 200 mg/kg group showing a plasma average concentration almost 4 times greater than the 35 mg/kg group (7.88 μM and 27.78 μM respectively) in SCID beige mice. AT-101 (25 mg/kg to 100 mg/kg, orally) indefinitely results in earlier onset of weight loss equivalent to more than 10% of the pretreatment weight and death in SCID beige mice. AT-101 (35 mg/kg, orally per day for 10 days) plus intraperitoneal cyclophosphamide (Cy) and intraperitoneal rituximab (R) show significantitumor volume control compared to any other treatment group. AT-101 (15 mg/kg, p.o., 5 days/week) as a single agent in intact mice significantly reduces the development of VCaP tumor growth compared to untreated tumors at weeks 2 to 6. AT-101 in combination with surgical castration delays the onset of androgen-independent VCaP tumor growth compared to castration-only or AT-101-only groups in mice.

• 细胞实验： Cells are counted and resuspended at an approximate concentration of 3×105 cells/well in a 24-well plate. AT-101 is diluted in DMSO that is maintained at a final concentration of less than 0.5%. Concentrations of AT-101 from 1 nM to 10 μM are used in most experiments. Following incubation at 37 ℃ in a 5% CO2 humidified incubator, 100 μL from each well is transferred to a 96-well opaque-walled plate; cell-Titer-Glo Reagent is added in a 1:1 ratio. Contents are mixed for 2 minutes on an orbital shaker to induce cell lysis. The plates are allowed to incubate at room temperature for 10 minutes before recording luminescence with a Synergy HT Multi-Detection Microplate Reader. In the schedule dependency experiments, serial dilutions of each drug are prepared in ratios relative to their IC50. Cells are preincubated with AT-101 for up to 72 hours, while 4-HC is added for a 24-hour period, being added at time 0, 24 hours, and 48 hours from the start of incubation. Each experiment is performed in triplicate and repeate
