product name NMS-P118
Description: NMS-P118 is a potent, orally available, and highly selective PARP-1 inhibitor with 150-fold selectivity for PARP-1 over PARP-2 (Kd 0.009 μM vs 1.39 μM, respectively). It has been investigated for cancer treatment. NMS-P118 has excellent ADME and pharmacokinetic properties, and is proved to be metabolically stable, it modestly inhibits two cytochrome P450 family members (CYP-2B6 IC50, 8.15 μM; CYP-2D6 IC50, 9.51 μM) out of eight isoforms tested. NMS-P118 has low in vivo clearance, and complete oral bioavailability.

In vitro activity: NMS-P118 is found to be less myelotoxic in vitro than olaparib (now marketed as Lynparza), a dual PARP-1/-2 inhibitor. NMS-P118 proves to be metabolically stable, it modestly inhibites two cytochrome P450 family members (CYP-2B6 IC50: 8.15 μM; CYP-2D6 IC50: 9.51 μM) out of eight isoforms tested. Its ability in hampering the proliferation of bone marrow cells is from 5 to > 60 times lower then olaparib according to the species. Kinase Assay: NMS-P118 is profiled on 56 different kinases (ABL, ACK1, AKT1, ALK, AUR1, AUR2, BRK, BUB1, CDC7/DBF4, CDK2/CYCA, CHK1, CK2, EEF2K, EGFR1, ERK2, EphA2, FAK, FGFR1, FLT3, GSK3beta, Haspin, IGFR1, IKK2, IR, JAK1, JAK2, JAK3, KIT, LCK, LYN, MAPKAPK2, MELK, MET, MNK2, MPS1, MST4, NEK6, NIM1, P38alpha, PAK4, POLYDATINGFRb, POLYDATINK1, PERK, PIM1, PIM2, PKAalpha, PKCbeta, PLK1, RET, SULU1, Syk, TLK2, TRKA, TYK2, VEGFR2, ZAP70). The IC50 values are found to be >10 μM for all enzymes tested. Cell Assay: NMS-P118 is dissolved in DMSO and diluted with appropriate medium before use. Cellular activity of PARP-1 inhibitors is assessed by measuring the inhibition of the hydrogen peroxide induced PAR formation in HeLa cells (ECACC). Cellular PAR levels are measured by immunocytochemistry, and quantified using an ArrayScan vTi instrument. |

| In Vivo | NMS-P118 is proved to be metabolically stable, it modestly inhibits two cytochrome P450 family members (CYP-2B6 IC50, 8.15 μM; CYP-2D6 IC50, 9.51 μM) out of eight isoforms tested. NMS-P118 has low in vivo clearance, and complete oral bioavailability. The pharmacokinetic profile of NMS-P118 in rat dosed iv at 10 mg/kg and orally at 10 and 100 mg/kg, mirrors that observed in the mouse, with oral bioavailability >65%, and linearity of exposure with dose. Its treatment dramatically decreases intratumoral PAR levels at 1, 2, and 6 h after administration and partial recovery of PAR levels is observed at 24 h. NMS-P118 shows excellent ADME and pharmacokinetic profiles, high oral availability in the mouse and rat, and high efficacy both as a single agent and in combination with Temozolomide in BRCA1-mutated MDA-MB-436 and BRCA2 deficient Capan-1 human tumor xenograft models, respectively. |
