Uses
ACHP is an IkB kinase inhibitor, which has dose-dependently inhibited cell growth with inhibition of phosphorylation of IκBα/p65 and NF-κB DNA-binding, down-regulation of NF-κB target genes and induced apoptosis in human myeloma cell lines.
Biological Activity
achp is an iκb kinase inhibitor. nuclear factor-kb (nf-kb) involved in cell survival and proliferation of multiple myeloma has been well established.
in vitro
achp is selective for ikkα and ikkβ over ikk3, syk and mapkkk4 (ic50 > 20 μm), dna binding activity of nf-κb is inhibited. achp is an effective blockade nf-κb pathway in multiple myeloma cell lines, and induces cell growth arrest and apoptosis. it was observed that nf-kb is constitutively activated in all human myeloma cell lines, thus confirming the previous studies. in addition, it was found the phosphorylation of p65 subunit of nf-kb besides the phosphorylation of ikba and the activation of nf-kb dna binding and that various target genes of nf-kb including bcl-xl, xiap, c-iap1, cyclin d1, and il-6 are up-regulated. 2-amino-6-[2-(cyclopropylmethoxy)-6-hydroxyphenyl]-4-piperidin-4-yl nicotinenitrile (achp) is a novel ikb kinase inhibitor. treatment of myeloma cells with achp showed the cell growth was efficiently inhibited (ic50 values ranging from 18 to 35 mmol/l) concomitantly with inhibition of the phosphorylation of ikba/p65 and nf-kb dna-binding, down-regulation of the nf-kb target genes, and then induction of apoptosis. in addition, the treatment of achp potentiated the cytotoxic effects of vincristine and melphalan (l-phenylalanine mustard), conventional antimyeloma drugs. these findings suggest that by blocking the antiapoptotic nature of myeloma cells endowed by the constitutive activation of nf-kb, ikb kinase inhibitors such as achp can sensitize myeloma cells to the cytotoxic effects of chemotherapeutic agents.
Enzyme inhibitor
This novel IKK inhibitor (FW = 364.44 g/mol; CAS 406208-42-2; Soluble to 20 mM in DMSO), also named 2-amino-6-[2-(cyclopropylmethoxy)-6hydroxyphenyl]-4-(4-piperidinyl)-3-pyridinecarbonitrile, targets IκB kinases, with respective IC50 values of 8.5 and 250 nM for IKKβ and IKKα. ACHP’s selectivity is indicated by its > 20-μM IC50 values toward IKK3, Syk, and MAPKKK4. Inhibition of the TNFα-mediated gene expression could occur at low ACHP concentration (<1 μmol/L), with higher concentrations (>10 μmol/L) required to inhibit the constitutive phosphorylation of p65, expression of NF-κB-mediated genes (e.g., CYCLIN D1, BCL-xL, XIAP, c-IAP1, and IL-6), ultimately achieving myeloma cytostasis. Such findings indicate that ACHP’s growth inhibitory effects may be mediated through inhibition of both IKKα and IKKβ. By inhibiting NF-κB’s DNA binding activity, ACHP blocks the NF-κB pathway in multiple myeloma cell lines, inducing growth arrest and apoptosis.
IC 50
8.5 and 250 nm for ikkβ and ikkα, respectively

Check Digit Verification of cas no
The CAS Registry Mumber 406208-42-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,6,2,0 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 406208-42:
(8*4)+(7*0)+(6*6)+(5*2)+(4*0)+(3*8)+(2*4)+(1*2)=112
112 % 10 = 2
So 406208-42-2 is a valid CAS Registry Number.
