Check Digit Verification of cas no

The CAS Registry Mumber 137076-54-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,0,7 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 137076-54:
(8*1)+(7*3)+(6*7)+(5*0)+(4*7)+(3*6)+(2*5)+(1*4)=131
131 % 10 = 1
So 137076-54-1 is a valid CAS Registry Number.

Solid-Phase Assisted N-1 Functionalization of Azamacrocycles

Oliver, Morag,Jorgensen, Michael R.,Miller, Andrew D.

, p. 453 - 456 (2004)

A simple solid-phase assisted strategy for the N-1 functionalization of azamacrocycles is described. Compounds such as cyclen, cyclam and piperazine can be selectively modified by temporary attachment to solid-phase resins providing an efficient and clean method to prepare biomedically interesting moieteies.

Cyclin A probes by means of intermolecular sensitization of terbium-chelating peptides

Pazos, Elena,Torrecilla, Daniel,Lopez, Miguel Vazquez,Castedo, Luis,Mascarenas, Jose L.,Vidal, Anxo,Vazquez, M. Eugenio

, p. 9652 - 9653 (2008)

Intermolecular sensitization of lanthanide ions was effectively implemented in the development of fluorescent sensors targeting cyclin A. A chelating unit has been conjugated to peptides containing a known cyclin A binding motif (CBM). Upon interaction of the modified terbium-chelating peptides with the cyclin A substrate recruitment groove, the Tb3+ ion is placed in the vicinity of the Trp217 side chain, which results in efficient intermolecular terbium sensitization and specific long wavelength fluorescent emission from the metal center.

A binary targeting vector that consists of peptide sequences of Arg-Gly-Asp (RGD) and Asn-Gly-Arg (NGR) motifs has been designed and synthesized using solid-phase peptide synthesis procedure. The vector is then coupled with Gd-DOTA to work as a targeting

Synthesis and characterisation of a novel tubulin-directed DO3A-colchicine conjugate with potential theranostic features

Wardle, Nicholas. J.,Kalber, Tammy,Bell, Jimmy D.,Bligh, S.W. Annie

, p. 3346 - 3348 (2011)

Colchicine is a known tubulin binding agent enabling necrosis in tumors. A novel tubulin-directed DO3A-colchicine conjugate and its Gd(III) complex were prepared from N-deacetylcolchicine, coupling alkaloid and polyaza-alicyclic functions via a peptide coupling methodology. The longitudinal proton relaxivity of the Gd(III) complex in water at 4.7 T is 2.86 mM-1 s-1 and a similar efficacy as colchicine towards ovarian carcinoma cells in vitro.

Fine-tuning the pH trigger of self-assembly

Ghosh, Arijit,Haverick, Mark,Stump, Keith,Yang, Xiangyu,Tweedle, Michael F.,Goldberger, Joshua E.

, p. 3647 - 3650 (2012)

The creation of smart, self-assembling materials that undergo morphological transitions in response to specific physiological environments can allow for the enhanced accumulation of imaging or drug delivery agents based on differences in diffusion kinetics. Here, we have developed a series of self-assembling peptide amphiphile molecules that transform either isolated from molecules or spherical micelles into nanofibers when the pH is slightly reduced from 7.4 to 6.6, in isotonic salt solutions that simulate the acidic extracellular microenvironment of malignant tumor tissue. This transition is rapid and reversible, indicating the system is in thermodynamic equilibrium. The self-assembly phase diagrams show a single-molecule-to-nanofiber transition with a highly concentration-dependent transition pH. However, addition of a sterically bulky Gd(DO3A) imaging tag on the exterior periphery shifts this self-assembly to more acidic pH values and also induces a spherical micellar morphology at high pH and concentration ranges. By balancing the attractive hydrophobic and hydrogen-bonding forces, and the repulsive electrostatic and steric forces, the self-assembly morphology and the pH of transition can be systematically shifted by tenths a pH unit.

Development of a dual functional luminescent sensor for zinc ion based on a peptidic architecture

Hirayama, Tasuku,Taki, Masayasu,Akaoka, Kazushi,Yamamoto, Yukio

, p. 7410 - 7413 (2012)

A synthetic peptide bearing a lanthanide complex, TbOTZ exhibits a decrease of chromophore fluorescence and a concomitant luminescence enhancement due to sensitized Tb3+ upon Zn2+ binding. Thus, TbOTZ can be a valuable tool for ratiometric sensing of Zn2+ as well as for time-resolved fluorescence detection with a single molecule.

Because of their unique photochemical and photophysical properties, luminescent lanthanide-based complexes have long captivated chemists. In recent years, the number of reports of luminescent lanthanide complex-based probes for monitoring of biological an

Photoresponsive host-guest chemistry and relaxation time of fluorinated cyclodextrin and T1=T* 2 arylazopyrazole-functionalized DOTA metal complexes

Simke, Julian,B?ckermann, Till,Bergander, Klaus,Klabunde, Sina,Hansen, Michael Ryan,Ravoo, Bart Jan

, p. 2186 - 2191 (2021)

Light-responsive modulation of the longitudinal (T1) and transversal T *2) relaxation times of a fluorinated cyclodextrin has been achieved by host-guest complexation with arylazopyrazole-modified metal complexes in aqueous solution. This supramolecular concept can potentially be applied to the development of contrast agents for19F magnetic resonance imaging (MRI).
