NQDI 1, an inhibitor of ASK1 attenuates acute ischemic renal injury by modulating oxidative stress and cell death.[Pubmed:23952292]
Cardiovasc Hematol Agents Med Chem. 2013 Sep;11(3):179-86.
Apoptosis signal-regulating kinase 1 (ASK1) is among the signaling events that lead to postischemic cell death. Inhibition of ASK1 pathway protected hearts from ischemic damage. The present study evaluated the renal protective effects of NQDI 1, an inhibitor of ASK1, in an animal model of acute ischemic renal failure. Male Wistar rats were subjected to right nephrectomy and clamping of left renal pedicle for 45 min, or sham operation. The administration of NQDI 1 attenuated renal dysfunction and histological changes characteristic for renal ischemia/reperfusion injury (IRI). Apoptosis of renal tissues, as detected by TUNEL staining, was also reduced together with p53 protein expression, and renal levels of MDA and SOD with NQDI 1 administration and BCL2 was up regulated. In conclusion, inhibition of ASK1 is of therapeutic potential against acute ischemic renal injury. Its protective effects are mediated via inhibition of apoptosis and oxidative stress.
NQDI-1, an inhibitor of ASK1 attenuates acute perinatal hypoxic-ischemic cerebral injury by modulating cell death.[Pubmed:27081917]
Mol Med Rep. 2016 Jun;13(6):4585-92.
Apoptosis signal-regulating kinase 1 (ASK1) is a ubiquitously expressed protein kinase, which regulates cell fate in numerous injury conditions. Therefore, ASK1 may be a promising novel therapeutic target for injury. However, the expression and distribution of ASK1 in the perinatal brain following hypoxia-ischemia (HI) remains to be elucidated. In the present study, western blotting and immunofluorescence were used to determine the expression and distribution of ASK1 and any associated downstream targets in the perinatal rat brain following HI. NQDI1, a specific inhibitor of ASK1 was intracerebroventricularly injected following neonatal rats brain insult for neuroprotection. The results revealed an increased expression of ASK1 and this expression was localized to the neurons and astrocytes, compared with the sham controls. Additionally, it was demonstrated that the ASK1/ cJun Nterminal kinases (JNK) pathway was involved in the brain damage following HI in neonatal rats. Notably, NQDI1 significantly inhibited the in vivo expression levels of ASK1, phosphorylated (p)JNK, pcJun, p53 and caspase 3. Reduced acute hypoxicischemic cerebral injury and cell apoptosis was observed following the injection of NQDI1. Collectively, NQDI-1 attenuated acute perinatal hypoxicischemic cerebral injury by inhibiting the expression of ASK1 and cell apoptosis. This may be a promising novel neuroprotective inhibitor for perinatal cerebra injury.
Identification of 3H-naphtho[1,2,3-de]quinoline-2,7-diones as inhibitors of apoptosis signal-regulating kinase 1 (ASK1).[Pubmed:21449566]
J Med Chem. 2011 Apr 28;54(8):2680-6.
Apoptosis signal-regulating kinase 1 (ASK1) has recently emerged as an attractive therapeutic target for the treatment of cardiac and neurodegenerative disorders. The selective inhibitors of ASK1 may become important compounds for the development of clinical agents. We have identified the ASK1 inhibitor among 3H-naphtho[1,2,3-de]quinoline-2,7-diones using receptor-based virtual screening. In vitro kinase assay revealed that ethyl 2,7-dioxo-2,7-dihydro-3H-naphtho[1,2,3-de]quinoline-1-carboxylate (NQDI-1) inhibited ASK1 with a K(i) of 500 nM. The competitive character of inhibition is demonstrated in Lineweaver-Burk plots. In our preliminary selectivity study this compound exhibited strong specific inhibitory activity toward ASK1.
Synthesis and cytotoxic activity of 7-oxo-7H-dibenz[f,ij]isoquinoline and 7-oxo-7H-benzo[e]perimidine derivatives.[Pubmed:11384245]
J Med Chem. 2001 Jun 7;44(12):2004-14.
A series of 7-oxo-7H-dibenz[f,ij]isoquinoline and 7-oxo-7H-benzo[e]perimidines bearing cationic side chains were prepared from aminoanthraquinones. The perimidines were prepared from 1-aminoanthraquinone by initial condensation with urea or dimethylacetamide. A series of 2-, 4-, 8-, and 11-carboxy derivatives of the dibenzisoquinolines were prepared from aminoanthraquinonecarboxylic acids. The cationic derivatives were prepared from these via amide, amine, or methylene linkers to study the effects of side chain positioning on biological activity. Within the series of carboxamide-linked compounds, the order of increasing cytotoxicity was 8- < 4- < 2- < 11-. The 2- and 4-carboxamides showed substantial growth delays against in vivo subcutaneous colon 38 tumors in mice, but the 11-carboxamide had curative activity in this refractory model and is being investigated further.
