| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |
||
| About Packaging | 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial. 2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial. 3. Try to avoid loss or contamination during the experiment. |

PARP1/2 inhibitors are a class of anticancer agents that target tumor-specific defects in DNA repair. BMN 673 is a highly potent PARP1/2 inhibitor.
In vitro: BMN 673 is a potent PARP1/2 inhibitor, but it does not inhibit other enzymes that we have tested. BMN673 exhibits selective antitumor cytotoxicity and elicits DNA repair biomarkers at much lower concentrations than earlier generation PARP1/2 inhibitors. BMN 673 targeted tumor cells with BRCA1, BRCA2, or PTEN gene defects selectively with 20- to more than 200-fold greater potency than existing PARP1/2 inhibitors in vitro [1].
In vivo: BMN 673 is readily orally bioavailable, with more than 40% absolute oral bioavailability in rats when dosed in CMC. Orally BMN 673 elicited remarkable antitumor activity in mice; xenografted tumors that carry defects in DNA repair due to BRCA mutations or PTEN deficiency were profoundly sensitive to oral BMN 673 treatment at well-tolerated doses. Synergistic antitumor effects were also found when BMN 673 was combined with temozolomide, SN38, or platinum drugs [1].
Clinical trial: Pharmacokinetics (PK), pharmacodynamics (PD), safety and anti-tumor activity of BMN 673 were evaluated in a 2-stage dose-escalation study with 3-6 patients (pts)/dose level. Results showed BMN 673 was well tolerated with impressive anti-tumor activity in pts with BRCA mut with a single agent recommended Phase II trial dose of 1000 μg/d due to dose-limiting thrombocytopenia.
