Check Digit Verification of cas no

The CAS Registry Mumber 22162-19-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,6 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 22162-19:
(7*2)+(6*2)+(5*1)+(4*6)+(3*2)+(2*1)+(1*9)=72
72 % 10 = 2
So 22162-19-2 is a valid CAS Registry Number.

Rational modification of a previously identified spirohydantoin lead structure has identified a series of potent spiroazaoxindole CGRP receptor antagonists. The azaoxindole was found to be a general replacement for the hydantoin that consistently improved

CYCLIC PEPTIDE ANALOGS OF MELANOCORTIN AND AMANITIN AND METHODS OF MAKING SUCH

-

, (2021/01/29)

The invention described herein is based in part on the discovery of a protein/peptide crosslink, which introduces fluorescent properties, and which has been applied to synthesize analogues of melanocortin and amanitin as choice peptides to be explored in the context of isoindole peptides. Without limitation, it is expected that those trained in the art of peptide synthesis and stapling would appreciate the consequences of this invention such that other peptides of varied length can be similarly constrained by isoindole staples as featured herein.

Fluorescent Isoindole Crosslink (FlICk) Chemistry: A Rapid, User-friendly Stapling Reaction

Todorovic, Mihajlo,Schwab, Katerina D.,Zeisler, Jutta,Zhang, Chengcheng,Bénard, Francois,Perrin, David M.

, p. 14120 - 14124 (2019/07/31)

The stabilization of peptide secondary structure via stapling is a ubiquitous goal for creating new probes, imaging agents, and drugs. Inspired by indole-derived crosslinks found in natural peptide toxins, we employed ortho-phthalaldehydes to create isoindole staples, thus transforming inactive linear and monocyclic precursors into bioactive monocyclic and bicyclic products. Mild, metal-free conditions give an array of macrocyclic α-melanocyte-stimulating hormone (α-MSH) derivatives, of which several isoindole-stapled α-MSH analogues (Ki≈1 nm) are found to be as potent as α-MSH. Analogously, late-stage intra-annular isoindole stapling furnished a bicyclic peptide mimic of α-amanitin that is cytotoxic to CHO cells (IC50=70 μm). Given its user-friendliness, we have termed this approach FlICk (fluorescent isoindole crosslink) chemistry.

Synthesis of 1,2-phenylenedimethanols by base-promoted reduction of isobenzofuran-1(3H)-ones with silane

Liu, Bin,Zhou, Xigeng

supporting information, p. 725 - 728 (2018/12/11)

An efficient method for preparation of substituted 1,2-phenylenedimethanols and aliphatic 1,4-diols that are valuable intermediates in organic synthesis, has been developed by the base-promoted reduction of isobenzofuran-1(3H)-ones and γ-lactones with silane under mild conditions. Compared with traditional procedures using stoichiometric amounts of metal hydrides and alkyl reductants, the present method avoids the use of sensitive reagents and is operationally simple and a broad variety of functional groups are tolerated.

Assessment of the regioselectivity in the condensation reaction of unsymmetrical o-phthaldialdehydes with alanine

D'Hollander, Agathe C.A.,Westwood, Nicholas J.

supporting information, p. 224 - 239 (2017/12/08)

One approach for the synthesis of isoindolinones, a privileged bioactive heterocyclic core structure, involves a condensation reaction of o-phthaldialdehydes with a suitable nitrogen-containing nucleophile. This fascinating reaction is revisited here in the context of the use of o-phthaldialdehydes that contain additional substituents in the aromatic ring leading to a detailed analysis of the regioselectivity of the reaction. Eleven monosubstituted o-phthaldialdehydes were synthesised and reacted with alanine. The regioselectivity observed across the eleven substrates led to the design of a disubstituted substrate that reacted with very high control. A gram-scale reaction followed by esterification gave one major regioisomer in high yield. In addition, the regioselectivity observed on reaction of two novel monodeuterated substrates led to an increased mechanistic understanding.
