Venadaparib
(Synonyms: IDX-1197) 目录号 : GC62129
Venadaparib (IDX-1197), a potent PARP1/2 inhibitor with IC50 values of 1.4 nM and 1.0 nM respectively, prevents the repair of DNA single-strand breaks (SSB) and promotes the conversion of SSB to double-stranded breaks (DSB), which ultimately leads to synthetic lethality in cancer cells.
Cas No.:1681017-83-3
Sample solution is provided at 25 µL, 10mM.

Venadaparib (IDX-1197), a potent PARP1/2 inhibitor with IC50 values of 1.4 nM and 1.0 nM respectively, prevents the repair of DNA single-strand breaks (SSB) and promotes the conversion of SSB to double-stranded breaks (DSB), which ultimately leads to synthetic lethality in cancer cells.
IDX-1197 potently, selectively inhibits PARP1 and PARP2 activities with no sensitivity to PARP5A (Tankyrase-1), and significantly inhibits PARP1-mediated PAR expression in DNA damage-induced Hela cells.[1]
In the germline BRCA1-mutated ovarian cancer PDX model, oral administration of IDX-1197 exhibits significant PAR inhibition in tumor tissues, and dose-dependently lead to potent tumor growth inhibition compared to Olaparib treatment group.[1]

Venadaparib Is a Novel and Selective PARP Inhibitor with Improved Physicochemical Properties, Efficacy, and Safety
Mol Cancer Ther 2023 Mar 2;22(3):333-342.PMID:36808277DOI:PMC9978881
PARP inhibitors have been approved by the FDA for use in the treatment of patients with ovarian, breast, pancreatic, and prostate cancers. PARP inhibitors show diverse suppressive effects on PARP family members and PARP-DNA trapping potency. These properties are associated with distinct safety/efficacy profiles. Here, we report the nonclinical characteristics of Venadaparib (also known as IDX-1197 or NOV140101), a novel potent PARP inhibitor. The physiochemical properties of Venadaparib were analyzed. Furthermore, the efficacy of Venadaparib against PARP enzymes, PAR formation, and PARP trapping activities, and growth inhibition of cell lines with BRCA mutations were evaluated. Ex vivo and in vivo models were also established to study pharmacokinetics/pharmacodynamics, efficacy, and toxicity. Venadaparib specifically inhibits PARP-1 and -2 enzymes. Oral administration of Venadaparib HCl at doses above 12.5 mg/kg significantly reduced tumor growth in the OV_065 patient-derived xenograft model. Intratumoral PARP inhibition remained at over 90% until 24 hours after dosing. Venadaparib had wider safety margins than olaparib. Notably, Venadaparib showed favorable physicochemical properties and superior anticancer effects in homologous recombination-deficient in vitro and in vivo models with improved safety profiles. Our results suggest the possibility of Venadaparib as a next-generation PARP inhibitor. On the basis of these findings, phase Ib/IIa studies on the efficacy and safety of Venadaparib have been initiated.
