156939-66-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 156939-66-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,9,3 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 156939-66:
(8*1)+(7*5)+(6*6)+(5*9)+(4*3)+(3*9)+(2*6)+(1*6)=181
181 % 10 = 1
So 156939-66-1 is a valid CAS Registry Number.

Rational Design of Right-Handed Heterogeneous Peptidomimetics as Inhibitors of Protein-Protein Interactions

Shi, Yan,Sang, Peng,Lu, Junhao,Higbee, Pirada,Chen, Lihong,Yang, Leixiang,Odom, Timothy,Daughdrill, Gary,Chen, Jiandong,Cai, Jianfeng

, p. 13187 - 13196 (2020)

Peptidomimetics have gained great attention for their function as protein-protein interaction (PPI) inhibitors. Herein, we report the design and investigation of a series of right-handed helical heterogeneous 1:1 α/Sulfono-I-AA peptides as unprecedented inhibitors for p53-MDM2 and p53-MDMX. The most potent helical heterogeneous 1:1 α/Sulfono-I-AA peptides were shown to bind tightly to MDM2 and MDMX, with Kd of 19.3 and 66.8 nM, respectively. Circular dichroism spectra, 2D-NMR spectroscopy, and the computational simulations suggested that these helical sulfono-I-AA peptides could mimic the critical side chains of p53 and disrupt p53/MDM2 PPI effectively. It was noted that these 1:1 α/Sulfono-I-AA peptides were completely resistant to proteolytic degradation, boosting their potential for biomedical applications. Furthermore, effective cellular activity is achieved by the stapled 1:1 α/Sulfono-I-AA peptides, evidenced by significantly enhanced p53 transcriptional activity and much more induced level of MDM2 and p21. The 1:1 α/Sulfono-I-AA peptides could be an alternative strategy to antagonize a myriad of PPIs.

1,2,3-Triazole Stabilized Neurotensin-Based Radiopeptidomimetics for Improved Tumor Targeting

Mascarin, Alba,Valverde, Ibai E.,Vomstein, Sandra,Mindt, Thomas L.

, p. 2143 - 2152 (2015/11/09)

Neurotensin (NT) is a regulatory peptide with nanomolar affinity toward NT receptors, which are overexpressed by different clinically relevant tumors. Its binding sequence, NT(8-13), represents a promising vector for the development of peptidic radiotracers for tumor imaging and therapy. The main drawback of the peptide is its short biological half-life due to rapid proteolysis in vivo. Herein, we present an innovative strategy for the stabilization of peptides using nonhydrolizable 1,4-disubstituted, 1,2,3-triazoles as amide bond surrogates. A triazole scan?of the peptide sequence yielded novel NT(8-13) analogues with enhanced stability, retained receptor affinity, and improved tumor targeting properties in vivo. The synthesis of libraries of triazole-based peptidomimetics was achieved efficiently on solid support by a combination of Fmoc-peptide chemistry, diazo transfer reactions, and the Cu(I)-catalyzed alkyne azide cycloaddition (CuAAC) employing methods that are fully compatible with standard solid phase peptide synthesis (SPPS) chemistry. Thus, the amide-to-triazole substitution strategy may represent a general methodology for the metabolic stabilization of biologically active peptides.

Synthesis of α, β-unsaturated γ-amino esters with unprecedented high (E)-stereoselectivity and their conformational analysis in peptides

Mali, Sachitanand M.,Bandyopadhyay, Anupam,Jadhav, Sandip V.,Kumar, Mothukuri Ganesh,Gopi, Hosahudya N.

supporting information; experimental part, p. 6566 - 6574 (2011/11/05)

Mild, efficient and racemization-free synthesis of N-protected α, β-unsaturated γ-amino esters with unprecedented high E- stereoselectivity is described. This method is found to be compatible with Boc-, Fmoc- and other side chain protecting groups. The crystal conformations of the vinylogous γ-amino esters in monomers and in homo- and mixed dipeptides are studied. Further, the vinylogous homo-dipeptide showed a β-sheet conformation, while mixed α- and α,β-unsaturated γ-hybrid dipeptide adapted an irregular structure in single crystals.
