Description
Zibotentan is a selective antagonist of the endothelin (ET) receptor type A (IC50s = 21 and >10,000 nM for human recombinant ETA and ETB, respectively). It inhibits growth of HEY, OVCA 433, SKOV3, and A2780 cells induced by endothelin 1 (ET-1; ) in vitro. Zibotentan reduces ET-1-induced expression of MMP-2, MMP-9, VEGF, COX-1 and COX-2, mediators of cell invasion and angiogenesis, in HEY cells. In vivo, zibotentan (10-50 mg/kg per day) reduces tumor growth in an HEY mouse xenograft model in a dose-dependent manner. Formulations containing zibotentan are under clinical investigation for the treatment of ovarian and castration-resistant prostate cancers.
Uses
Zibotentan is a specific endothelin-A receptor antagonist that is a potential candidate in the treatment of prostate cancer, bone metastasis and various other types of cancer.
in vitro
in the human ovarian cancer etar positive cell lines, zd4054 effectively inhibited the basal and et-1-induced cell proliferation, with the inhibition of akt and p42/44mapk phosphorylation, and increased apoptosis, through the inhibition of bcl-2 and activation of caspase-3 and poly(adp-ribose) polymerase proteins. [1].
in vivo
in hey ovarian cancer xenografts, zd4054 inhibited tumor growth to the same degree as paclitaxel. moreover, zd4054-dependent tumor growth inhibition was associated with a reduction in proliferation index, mmp-2 expression, and microvessel microvessel density [2].

Check Digit Verification of cas no
The CAS Registry Mumber 186497-07-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,4,9 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 186497-07:
(8*1)+(7*8)+(6*6)+(5*4)+(4*9)+(3*7)+(2*0)+(1*7)=184
184 % 10 = 4
So 186497-07-4 is a valid CAS Registry Number.
