    Journal, PARP Biomarker:  Affinity Chromatographic Method for Determining Drug-Protein Interaction with Enhanced Speed Than Typical Frontal Analysis. (Pubmed Central) -  Oct 22, 2023   
    The method was high speed since it allowed simultaneous determination of binding parameters between two drugs and a protein with a smaller number of experiments to be performed. Such a feature made the method an attractive alternative for high-speed analysis of drug-protein interaction or the other bindings in a binary system.

    P2
    Given the subsequent lack of efficacy demonstrated for iniparib in breast cancer, these are studies of GC and demonstrate a higher than traditionally appreciated activity in patients with platinum-sensitive and -resistant recurrent ovarian cancer, especially in patients that harbor a BRCA mutation, resetting the benchmark for efficacy in phase II trials. (ClinicalTrials.gov Identifiers: NCT01033292 & NCT01033123).

    We recently showed that while partial poly(ADP-ribose) polymerase (PARP)-1 inhibition with a low metronomic sub-half-maximal inhibitory concentration/dose (IC50) of olaparib provides superior protection against colon cancer in mice compared to complete inhibition by blocking the suppressive function of myeloid-derived suppressor cells (MDSCs) and synergizing with anti-program cell death (PD)-1-based immunotherapy...A sub-IC50 concentration of other clinically used PARPi (rucaparib, niraparib, and talazoparib) as well as the failed PARPi, iniparib, exerted similar effects...Thus, PARPi-based metronomic therapy may promote functional changes in myeloid cells that provide an additional rationale for combining it with immunotherapy. Our results also provide new opportunities for iniparib in cancer therapy.

    Journal:  Crystal structures of the catalytic domain of human PARP15 in complex with small molecule inhibitors. (Pubmed Central) -  Aug 13, 2022   
    Here, we solved high-resolution crystal structures of the human PARP15 catalytic domain in complex with three marketed drugs of PARP inhibitors, which includes compounds 3-AB, iniparib and niraparib. The structures reported here contribute to our understanding of the ligand binding modes and structural features in the PARP15 catalytic domain, which can be employed to guide the rational design of selective inhibitors of PARPs.

    Journal:  Biodegradable Oxygen-producing Manganese-chelated Metal Organic Frameworks for Tumor-targeted Synergistic Chemo/photothermal/ photodynamic Therapy. (Pubmed Central) -  Jan 28, 2022   
    Herein, to overcome tumor-associated hypoxia, and further achieve tumor-targeted synergistic chemotherapy/PDT/photothermal therapy (PTT), we have constructed a biodegradable oxygen-producing nanoplatform (named Ini@PM-HP), which was composed of the porous metal-organic framework (PCN-224(Mn)), the poly (ADP-ribose) polymerase (PARP) inhibitor (Iniparib), and the polydopamine-modified hyaluronic acid (HA-PDA)...STATEMENT OF SIGNIFICANCE: A delicately designed biodegradable oxygen-producing nanoplatform Ini@PM-HP is constructed to achieve combination therapy of solid tumors. Taking advantage of the active-targeting, PTT, enhanced PDT and PARPi, this nanotherapeutic approach successfully enables the combined chemo/photothermal/photodynamic therapy with great inhibition of solid tumors.

    Clinical, Journal:  Fooled by randomness. The misleading effect of treatment crossover in randomized trials of therapies with marginal treatment benefit. (Pubmed Central) -  Jan 21, 2022   
    Taking advantage of the active-targeting, PTT, enhanced PDT and PARPi, this nanotherapeutic approach successfully enables the combined chemo/photothermal/photodynamic therapy with great inhibition of solid tumors. Crossover can bias clinical outcomes of randomized clinical trials by increasing the risk of both type I (false positive) and type II (false negative) error.To show how crossover can increase type I error, we provide computer simulation and review herein illustrative examples (iniparib, olaratumab) of recently reported RCTs that demonstrated false positive treatment efficacy signals due to crossover.The ethic issues associated to crossover are also discussed.

    Journal, PARP Biomarker:  CRISPR/Cas9-mediated mutagenesis at microhomologous regions of human mitochondrial genome. (Pubmed Central) -  Jan 7, 2022   
    InDel mutagenesis was significantly improved by sgRNA multiplexing and a DSB repair inhibitor, iniparib, demonstrating the evidence of rewiring DSB repair status to manipulate mtDNA using CRISPR/Cas9. These findings would provide novel insights into mtDNA mutagenesis and mitochondrial gene therapy for diseases involving pathogenic mtDNA.

    It showed synergy with iniparib and another metabolic inhibitor (TEPP46). Targeting de novo fatty acid synthesis by inhibiting ACC is a promising therapeutic strategy.

    Platinum-containing chemotherapy remains a highly recommended therapeutic regimen due to greater effectiveness and tolerance for patients with advanced TNBC. The tools presented here should be of general use for building and using predictive multivariate signatures in oncology and in other therapeutic areas.

    Early investigations show tolerability of iniparib in dogs...Mutations in the canine BRCA2 gene have the potential to be exploited in clinical therapy through the usage of PARP inhibitors. However, further investigations are needed before introducing PARP inhibitors in veterinary clinical practice.

    Journal:  PET of Poly (ADP-Ribose) Polymerase Activity in Cancer: Preclinical Assessment and First In-Human Studies. (Pubmed Central) -  May 24, 2017   
    The area under the receiver operating characteristic curve (AUC, in g/mL· min) for (18)F-FTT was assessed in normal mouse organs before and after treatment with olaparib (n = 14), a PARP inhibitor, or iniparib (n = 11), which has no PARP inhibitory activity. Conclusion The results suggest that (18)F-FTT uptake reflects PARP expression and that its radiation dosimetry profile is compatible with those of agents currently in clinical use.
