1453834-21-3 Usage
Description
LDC-4297 is an inhibitor of cyclin-dependent kinase 7 (CDK7; IC50 = <5 nM). It is selective for CDK7 over CDK4, CDK6, and CDK9 (IC50s = >10, >10, and 1.71 μM), however, it also inhibits CDK2 and CDK1 (IC50s = 6.4 and 53.7 nM, respectively). LDC-4297 (10-100 nM) induces apoptosis in A549, HeLa, and HCT116 cancer cells in a concentration-dependent manner. It inhibits human cytomegalovirus (HCMV) replication in human fibroblasts (EC50 = 24.5 nM). LDC-4297 also reduces replication of Herpesviridae, Adenoviridae, Poxviridae, Retroviridae, and Orthomyxoviridae family viruses (EC50s = 0.02-1.13 μM).
Uses
Cyclin-dependent protein kinase 7 (CDK7) is involved with a broad range of regulatory roles in cell cycle and transcription, which is essential for viral replication. LDC 4297 is a CDK7 inhibitor that can be used to develop antiviral drugs.
Check Digit Verification of cas no
The CAS Registry Mumber 1453834-21-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,3,8,3 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1453834-21:
(9*1)+(8*4)+(7*5)+(6*3)+(5*8)+(4*3)+(3*4)+(2*2)+(1*1)=163
163 % 10 = 3
So 1453834-21-3 is a valid CAS Registry Number.
