187101-52-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 187101-52-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,1,0 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 187101-52:
(8*1)+(7*8)+(6*7)+(5*1)+(4*0)+(3*1)+(2*5)+(1*2)=126
126 % 10 = 6
So 187101-52-6 is a valid CAS Registry Number.

New 2,9-disubstituted-1,10-phenanthroline derivatives with anticancer activity by selective targeting of telomeric G-quadruplex DNA

Craciun, Anda-Mihaela,Rotaru, Alexandru,Cojocaru, Corneliu,Mangalagiu, Ionel I.,Danac, Ramona

, (2021)

Fifteen new 1,10-phenanthrolines disubstituted at positions 2 and 9 via amide bonds with different heterocycles have been designed and synthesized as G-quadruplex DNA stabilizers. Ten compounds were evaluated for the in vitro anticancer activity against 60 human tumor cell lines panel, four of them showing a very good inhibitory activity on several cell lines. To assess the ability of the most active compounds to interact with G-quadruplex DNA (G4-DNA), circular dichroism experiments were performed. The potency of the compounds to stabilize the G4-DNA has been shown from the thermal denaturation experiments. The mechanism of compounds binding to DNA and to G4-DNA was theoretically investigated by molecular docking studies. The experimental results demonstrated excellent capacity of the two compounds bearing two pyridin-3-yl residues (methylated and non-methylated) to act as selective G-quadruplex binders with promising anticancer activity.

2- and 3-substituted imidazo[1,2-a]pyrazines as inhibitors of bacterial type IV secretion

Sayer, James R.,Walldn, Karin,Pesnot, Thomas,Campbell, Frederick,Gane, Paul J.,Simone, Michela,Koss, Hans,Buelens, Floris,Boyle, Timothy P.,Selwood, David L.,Waksman, Gabriel,Tabor, Alethea B.

A novel series of 8-amino imidazo[1,2-a]pyrazine derivatives has been developed as inhibitors of the VirB11 ATPase HP0525, a key component of the bacterial type IV secretion system. A flexible synthetic route to both 2- and 3-aryl substituted regioisomers has been developed. The resulting series of imidazo[1,2-a]pyrazines has been used to probe the structure-activity relationships of these inhibitors, which show potential as antibacterial agents.
