  • Propofol inhibited the increase of PARP-1׳s expression and activity. Mice (n=6) were injected intraperitoneally with propofol, INO-1001 (a PARP-1 inhibitor) or equal volume of normal saline (NS), and then were trained with objects. Naïve animals were injected with normal saline and trained without objects (the same as habituation). 30 min after acquisition trial, the hippocampal tissues were harvested for determining PARP-1 (A and B) and PAR (C and D) expression by Western blot. Histogram represented the relative level normalized to naïve. *P<0.05, **P<0.01.

    Effect of DPQ and INO-1001 on ADP-, collagen- or PAR1ap-induced platelet aggregation. Human PRP samples were preincubated with PARP inhibitor (50 μM) or its vehicle and then stimulated with ADP (1.5 to 5 μM; to produce a biphasic aggregation curve), collagen (1 to 2 μg/ml) or PAR1ap (1 to 2 μM). Results are expressed relatively to platelet agonist alone (=vehicle group; normalized to 100%) and presented as the mean±SD (n=5-6).

Biological Activity

Description INO-1001 is a potent inhibitor of PARP with IC50 of <50 nM in CHO cells and a mediator of oxidant-induced myocyte dysfunction during reperfusion. Phase 2.
PARP [1]
<50 nM
In vitro

INO-1001 (>1 μM) leads to more than 95% inhibition of PARP activity without significant cellular toxicity. In addition, INO-1001 significantly sensitizes CHO cells by blocking most of the DNA repair occurring between radiation fractions. [1] Inhibition of PARP activity by INO-1001 significantly improves endothelial function by enhancing the acetylcholine-induced, endothelium-dependent, nitric oxide mediated vasorelaxation after exposure with 400 μM H2O2. [2]

In vivo In a db/db (Leprdb/db) mouse model, INO-1001 ameliorates diabetes-induced albumin excretion and mesangial expansion, and also decreases diabetes-induced podocyte depletion. [3] Treatment with INO-1001 (1.6 mg/kg via intracerebral injection) prevents NAD+ depletion and improves water maze performance after controlled cortical impact (CCI) in mice. [4]

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
