Check Digit Verification of cas no

The CAS Registry Mumber 1290536-55-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,0,5,3 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1290536-55:
(9*1)+(8*2)+(7*9)+(6*0)+(5*5)+(4*3)+(3*6)+(2*5)+(1*5)=158
158 % 10 = 8
So 1290536-55-8 is a valid CAS Registry Number.

Rhenium and technetium-complexed silicon rhodamines as near-infrared imaging probes for bimodal SPECT- And optical imaging

Boros, Eszter,Kanagasundaram, Thines,Kopka, Klaus,Kramer, Carsten S.

, p. 7294 - 7298 (2020)

Fluorescent Si-rhodamines were modified to enable complexation with the Re(i)- and99mTc(i)-tricarbonyl core. The corresponding complexes exhibit suitable properties as bimodal imaging probes for SPECT- and optical imagingin vitro. Importantly,

Development of Theragnostic Tool Using NIR Fluorescence Probe Targeting Mitochondria in Glioma Cells

Chu, Yeonjeong,Shin, Min Chul,Sung, June,Park, Jongmin,Kim, Eunha,Lee, Sanghee

, p. 1642 - 1648 (2019)

Because mitochondria are essential organelles for regulating energy homeostasis and intrinsic apoptosis, the perturbation of mitochondrial functions has been considered as an anticancer treatment. In this study, a new near-infrared (NIR) fluorescent probe

Improved Xanthone Synthesis, Stepwise Chemical Redox Cycling

Bachman, James L.,Escamilla, P. Rogelio,Boley, Alexander J.,Pavlich, Cyprian I.,Anslyn, Eric V.

, p. 206 - 209 (2019)

A base-catalyzed direct oxidation of rhodamine, carborhodamine, and siliconrhodamine pyronines to the corresponding xanthones is studied. This methodology utilizes addition of water to split pyronines into xanthone and reduced xanthene, the latter of whic

The unprecedented J-aggregate formation of rhodamine moieties induced by 9-phenylanthracenyl substitution

Kim, Sooyeon,Fujitsuka, Mamoru,Tohnai, Norimitsu,Tachikawa, Takashi,Hisaki, Ichiro,Miyata, Mikiji,Majima, Tetsuro

, p. 11580 - 11583 (2015)

We report a substitution of 9-phenylanthracenyl group into rhodamine derivatives that can induce the J-aggregate formation of rhodamine moieties in the aqueous solution upon the addition of a halide ion. From X-ray crystallographic analysis, the dramatic red-shift in the absorption band (i.e. app. 100 nm) originates from the cooperative slipped-stacking of rhodamine and anthracene molecules.

Zn ratiometric fluorescent probe and preparation and application thereof

-

, (2021/03/31)

The invention provides a Zn ratiometric fluorescent probe and preparation and application thereof. The preparation method of the Zn ratiometric fluorescent probe comprises the following steps: dissolving silicopyrone in CH3CN at 0 DEG C in a nitrogen environment, stirring for 10 minutes, dropwise adding trifluoromethanesulfonic anhydride, stirring to react for 10 minutes, adding N,N, di (2-pyridylmethyl) ethylenediamine, stirring the mixture overnight at room temperature, removing the solvent under reduced pressure, and carrying out column chromatography separation to obtain the fluorescent probe. Ratio detection is realized by utilizing a hydrolysis principle, and the reaction belongs to an irreversible reaction and can be used for quantitatively detecting zinc ions.

Method for distinguishing cancer cells/tissues with high contrast ratio and preparation of fluorescent probe

-

Paragraph 0017; 0045-0047, (2021/07/01)

The invention provides a method for distinguishing cancer cells/tissues with high contrast and preparation of a high-activity oxide (hROS) fluorescent probe. The structural formula of the probe is as shown in the specification. In the structural formula, R is -CH3, -CH2CH3, -CH(CH3)2 or -Ph. According to the invention, high-contrast fluorescence diagnosis of tumor cells/tissues is realized by utilizing a strategy of selectively inducing ROS amplification in cancer cells in virtue of beta-Lap and cooperatively using the fluorescent probe PSiR3 synthesized by the invention. The average fluorescence density ratio of cancer cells to normal cells is 15, the average fluorescence density ratio of cancer tissues to normal tissues is 24, and the average fluorescence density ratio far exceeds the clinically acceptable threshold value of 2.0. Importantly, in consideration of the high background ROS level of inflammatory cells, tumor tissues and inflammatory tissues can be distinguished by using the dual combined strategies of the PSiR3 and PSiR3/beta-Lap provided by the invention.
