BMN 673 Chemical Properties,Usage,Production
Description
Talazoparib (BMN 673) is a novel PARP inhibitor with IC50 of 0.58 nM in a cell-free assay. It is also a potent inhibitor of PARP-2, but does not inhibit PARG and is highly sensitive to PTEN mutation. Phase 3.
Features
Most potent and selective PARPi reported thus far.
In vitro
BMN-673 selectively binds to PARP and prevents PARP-mediated DNA repair of single strand DNA breaks via the base-excision repair pathway. This enhances the accumulation of DNA strand breaks, promotes genomic instability and eventually leads to apoptosis. BMN 673 selectively kills cancer cells with BRCA-1 or BRCA-2 mutations. BMN 673 demonstrates single-agent cytotoxicityin BRCA-1 mutant (MX-1, IC50 = 0.3 nM) and BRCA-2 mutant cells (Capan-1, IC50 = 5 nM). In contrast, in MRC-5 normal human fibroblastand other tumor cell lines with wild-type BRCA-1 and BRCA-2 genes, IC50 of BMN 673 ranges between 90 nM and 1.9 μM. In cultured human cancer cells, BMN 673 also significantly enhances the cytotoxic efficacy of both Temozolomide and SN-38. Off-target molecular screening did not identify significant non-specific activity for this class of PARP inhibitors.
In vivo
In rat pharmacokinetic studies, BMN 673 displays >50% oralbioavailability and pharmacokinetic properties that enable singledaily dosing. In MX-1 xenograft tumor model studies, daily oral dosingof BMN 673 significantly enhances the antitumor effects ofcytotoxic therapies in a dose-dependent manner.
Uses
BMN 673 is a pyrrolopyrazine derivative and anpoly (ADP-ribose) polymerase (PARP) inhibitor for patients with advanced or recurrent solid tumors such as ovarian and breast cancer.
Biological Activity
bmn673 is a potent and selective parp1/2 inhibitor with ki of 1.2 and 0.9 nm, respectively 1. it had no effect on panels of 72 receptors, ion channels, and enzymes 1. bmn673 showed ic50 value of 0.57 nm in enzymatic assay of parp1 1. in in vitro assay, it exhibited greater potency than other existing parp inhibitors, such as veliparib, rucaparib, and olaparib 2. it is also much more potent at trapping parp-dna complexes than other parp inhibitors 3.bmn673 has shown anti-tumor activity both in vitro and in vivo. it inhibited proliferation of tumor cells and xenografts with defects in homologous recombination 1. the combination of bmn673 and dna-damaging agents demonstrated synergistic anti-tumor effects 1. in addition, study showed that the expression levels of dna repair proteins and status of pi3k pathway predict response to bmn673 in small cell lung cancer 4.bmn673 is currently under investigation in multiple
Enzyme inhibitor
This novel, orally bioavailable poly(ADP-ribose) polymerase, or PARP, inhibitor (FW = 380.35 g/mol; CAS 1207456-01-6), also known as (8S,9R)- 5-fluoro-8-(4-fluorophenyl)-9-(1-methyl-1H-1,2,4-triazol-5-yl)-8,9-dihydro- 2H-pyrido[4,3,2-de]phthalazin-3(7H)-one, targets PARP-mediated DNA repair (IC50 = 0.58 nM) of single-strand DNA breaks by the base-excision repair pathway. By enhancing the accumulation of DNA strand breaks, BMN 673 promotes genomic instability, eventually leading to apoptosis. BMN 673 exhibits selective anti-tumor cytotoxicity and elicits DNA repair biomarkers at much lower concentrations than earlier generation PARP1/2 inhibitors, including olaparib, rucaparib and veliparib. BMN 673 shows remarkable anti-tumor activity in vivo, with strong action against xenografted tumors carrying defects in DNA repair due to BRCA mutations or PTEN deficiency. Synergistic or additive anti-tumor effects are observed, when BMN 673 was combined with temozolomide, SN38 or platinum drugs.
