1353550-13-6 Usage
Uses
Used in Oncology:
Olmutinib is used as an epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) for the treatment of non-small cell lung cancer (NSCLC). It is particularly effective against EGFR T790M mutation-positive NSCLC, as it inhibits both EGFR activating and T790M resistance mutations while sparing wild-type EGFR. This third-generation EGFR TKI has shown promise in overcoming resistance developed to earlier generations of EGFR tyrosine kinase inhibitor therapy, providing a new treatment option for patients with NSCLC who have developed resistance to first and second-generation EGFR TKIs.
Synthesis
Synthetically, olmutinib can be accessed in two steps
beginning with 2,4-dichloro-thieno[3,2-d]pyrimidine (147), which is commercially available and can be
prepared in two steps from urea and 3-aminothiophene 2-
carboxylate. Nucleophilic addition of N-(3-hydroxyphenyl)-2-
propenamide (148) to 147 proceeded with complete
regioselectivity via treatment with K2CO3 in warm DMSO,
smoothly providing the desired diaryl ether 149 in 87% yield
after crystallization from isopropanol and water. From
149, substitution with commercially available piperazinyl aniline
150 under acidic heating conditions (DMA, IPA, TFA, 90 °C)
provided olmutinib in 82% yield. After recrystallization,
olmutinib (XVI) was obtained in 60% overall yield and
99.1% purity.
in vitro
olmutinib has been identified as an irreversible kinase inhibitor and could covalently bind to a cysteine residue near the kinase domain of mutant egfr. olmutinib had a half-life of over 24h for egfr inhibition. olmutinib was able to cause potent inhibition in cell lines h1975 (l858r and t790m) and hcc827 (exon 19 deletion). olmutinib showed a low potency for nsclc cell line h358 with wild-type egfr [1].
in vivo
the previous in vivo studies of xenograft models with grafts of h1975 and hcc827 showed that olmutinib was active against the tumors without dasplaying any side effects [1].

Check Digit Verification of cas no
The CAS Registry Mumber 1353550-13-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,3,5,5 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1353550-13:
(9*1)+(8*3)+(7*5)+(6*3)+(5*5)+(4*5)+(3*0)+(2*1)+(1*3)=136
136 % 10 = 6
So 1353550-13-6 is a valid CAS Registry Number.
