Check Digit Verification of cas no

The CAS Registry Mumber 13122-90-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,2 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 13122-90:
(7*1)+(6*3)+(5*1)+(4*2)+(3*2)+(2*9)+(1*0)=62
62 % 10 = 2
So 13122-90-2 is a valid CAS Registry Number.

Prostate-specific membrane antigen (PSMA), also known as glutamate carboxypeptidase II (GCPII), is a suitable target for specific delivery of antitumor drugs and diagnostic agents due to its overexpression in prostate cancer cells. In the current work, we describe the design, synthesis, and biological evaluation of novel low-molecular PSMA ligands and conjugates with fluorescent dyes FAM-5, SulfoCy5, and SulfoCy7. In vitro evaluation of synthesized PSMA ligands on the activity of PSMA shows that the addition of aromatic amino acids into a linker structure leads to a significant increase in inhibition. The conjugates of the most potent ligand with FAM-5 as well as SulfoCy5 demonstrated high affinities to PSMA-expressing tumor cells in vitro. In vivo biodistribution in 22Rv1 xenografts in Balb/c nude mice of PSMA-SulfoCy5 and PSMA-SulfoCy7 conjugates with a novel PSMA ligand demonstrated good visualization of PSMA-expressing tumors. Also, the conjugate PSMA-SulfoCy7 demonstrated the absence of any explicit toxicity up to 87.9 mg/kg.

A catalytic one-step synthesis of peptide thioacids: the synthesis of leuprorelin via iterative peptide-fragment coupling reactions

supporting information, p. 12222 - 12225 (2018/12/01)

A catalytic one-step synthesis of peptide thioacids was developed. The oxygen-sulfur atom exchange reaction converted the carboxy group at the C-terminus of the peptides into a thiocarboxy group with suppressed epimerization. This method was successfully applied to the synthesis of the peptide drug leuprorelin via an iterative fragment-coupling protocol.

Synthesis and photochemical reactivity of phthalimidoadamantane–tyrosine conjugates

Sohora, Margareta,Vidovi?, Nikolina,Mlinari?-Majerski, Kata,Basari?, Nikola

, p. 5305 - 5320 (2017/09/23)

Abstract: Dipeptide 3, tetrapeptide 4 and pentapeptide 5, containing adamantylphthalimide and tyrosine, were synthesized and their photochemical reactivity investigated. Upon excitation to the triplet excited state, 3 does not give any photoproduct, although the photoinduced electron transfer (PET) should take place based on the thermodynamic properties. Tetrapeptide 4 and pentapeptide 5 are photochemically reactive, undergoing decomposition upon excitation. The lack of anticipated photodecarboxylation reactivity is explained by PET between the tyrosine and the phthalimide. However, deprotonation of the phenoxyl radical-cation giving phenoxyl radicals or back electron transfer giving starting material are probably faster than intrastrand single electron transfer which would lead to carboxyl radical and decarboxylation. The results indicate the importance of fine-tuning the molecular structure to attain the desired photoreactivity by the right choice of the reactants redox potential, as well as their acid/base properties.

A synthetic amino acid residue containing a new oligopeptide-based photosensitive fluorescent organogel

Maiti, Dibakar Kumar,Banerjee, Arindam

supporting information, p. 113 - 120 (2013/02/26)

A synthetic amino acid (with a stilbene residue in the main chain) containing a tripeptide-based organogelator has been discovered. This peptide-based synthetic molecule 1 self-assembles in various organic solvents to form an organogel. The gel has been thoroughly characterized by using various microscopic techniques including field-emission scanning electron microscopy (FESEM), atomic force microscopy (AFM), X-ray diffraction (XRD), UV-visible and fluorescence spectroscopy, and rheology. Morphological investigations using FESEM and AFM show a nanofibrillar network structure. Interestingly, the organogel is photoresponsive and a gel-sol transition occurred by irradiating the gel with UV light of 365 nm for 2 h as shown by the UV and fluorescence study. This photoresponsive fluorescent gel holds promise for new peptide-based soft materials with interesting applications. Copyright
