122772-21-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 122772-21-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,7,7 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 122772-21:
(8*1)+(7*2)+(6*2)+(5*7)+(4*7)+(3*2)+(2*2)+(1*1)=108
108 % 10 = 8
So 122772-21-8 is a valid CAS Registry Number.

New 1,2,4-triazole-Chalcone hybrids induce Caspase-3 dependent apoptosis in A549 human lung adenocarcinoma cells

Ahmed, Fatma F.,Abd El-Hafeez, Amer Ali,Abbas, Samar H.,Abdelhamid, Dalia,Abdel-Aziz, Mohamed

, p. 705 - 722 (2018/04/17)

A series of novel 1, 2, 4-triazole/chalcone hybrids was prepared and identified with different spectroscopic techniques. The prepared compounds showed remarkable cytotoxic activity against different cancer cell lines. Compounds 24, 25, 27, 41 and 47 had shown the highest cytotoxicity among the tested compounds against human lung adenocarcinoma A549 cells with IC50 ranging from 4.4 to 16.04 μM compared to cisplatin with IC50 of 15.3 μM. Flow cytometric analysis of the tested compounds showed an increase in the number of apoptotic cells in a dose-dependent manner. The further mechanistic study demonstrated that 1, 2, 4-triazole-chalcone hybrids induced apoptosis via increased level of proapoptotic protein Bax, release of cytochrome c from mitochondria and activation of caspase-3/8/9 proteins. However, general caspase inhibition by the pan-caspase inhibitor, z-VAD-fmk, significantly decreased the apoptosis induced by the tested hybrids, suggesting dependency of apoptosis on activation of the caspase-3 pathway.

New nitric oxide donating 1,2,4-triazole/oxime hybrids: Synthesis, investigation of anti-inflammatory, ulceroginic liability and antiproliferative activities

Abdel-Aziz, Mohamed,Abuo-Rahma, Gamal El-Din A.A.,Beshr, Eman A.M.,Ali, Taha F.S.

, p. 3839 - 3849 (2013/07/19)

A series of novel nitric oxide (NO) donating triazole/oxime hybrids was prepared and evaluated for their anti-inflammatory activity. Most of the tested compounds showed significant anti-inflammatory activity using carrageenan-induced rat paw edema method compared to indomethacin. Calculation of the ulcer indices and histopathological investigation indicated that the prepared NO-donating oximes exhibited less ulcerogenicity compared to their intermediate ketones and indomethacin. The NO-donating oxime 6i revealed significant activity against renal cancer A498 cell lines with 50.52 cell growth inhibition.
