334792-87-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 334792-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,4,7,9 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 334792-87:
(8*3)+(7*3)+(6*4)+(5*7)+(4*9)+(3*2)+(2*8)+(1*7)=169
169 % 10 = 9
So 334792-87-9 is a valid CAS Registry Number.

Fluorescent non-peptidic RGD mimetics with high selectivity for αvβ3 vs αiIbβ3 integrin receptor: Novel probes for in vivo optical imaging

Alsibai, Wael,Hahnenkamp, Anke,Eisenbl?tter, Michel,Riemann, Burkhard,Sch?fers, Michael,Bremer, Christoph,Haufe, Günter,H?ltke, Carsten

, p. 9971 - 9982 (2015/02/02)

Integrins are heterodimeric transmembrane protein receptors consisting of different α and β subunits. αvβ3 integrins are overexpressed on many tumor cells and tumor-associated angiogenic vessels, whereas αIIbβ3 is a receptor for, e.g., fibrinogen and mediates platelet aggregation. In this study, a near-infrared fluorescent imaging probe has been designed and synthesized by conjugating fluorescent dyes to a non-peptidic, pharmacophore-based ligand, based on a molecular modeling design approach. Affinity values were determined, and in vitro cell binding assays and preliminary in vivo xenograft studies in nude mice were performed to evaluate target binding. Competition assays revealed excellent binding and selectivity to αvβ3 compared to that for αIIbβ3. In vitro, the probe showed high target binding on αvβ3-positive M-21 cells and negligible binding to αvβ3-negative MCF-7 cells. In vivo, the tracer is able to image target expression in U-87 xenografts with a maximum signal-to-noise ratio (SNR) of 2.5:1 at 24 h after injection.
