Hydroxy-PEG6-CH2CO2tBu is a PEG (polyethylene glycol) linker that features a hydroxyl group and a t-butyl protected carboxyl group. This molecule is designed to enhance solubility in aqueous environments due to the hydrophilic PEG spacer. The presence of the hydroxyl group allows for further chemical modifications, such as derivatization or substitution with other reactive functional groups. Additionally, the t-butyl protected carboxyl group can be removed under acidic conditions, providing versatility in its applications.

Check Digit Verification of cas no

The CAS Registry Mumber 297162-47-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,7,1,6 and 2 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 297162-47:
(8*2)+(7*9)+(6*7)+(5*1)+(4*6)+(3*2)+(2*4)+(1*7)=171
171 % 10 = 1
So 297162-47-1 is a valid CAS Registry Number.

Paragraph 1592; 1593, (2021/02/12)

The present disclosure relates to bifunctional compounds, which find utility as modulators of tan protein. In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a VHL or cereblon ligand which binds to the E3 ubiquitin ligase and on the other end a moiety which binds tan protein, such that tan protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of tan. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of tan protein. Diseases or disorders that result from aggregation or accumulation of tan protein are treated or prevented with compounds and compositions of the present disclosure.

Proteolysis targeting chimeras (PROTACs) are bifunctional molecules that recruit an E3 ligase to a target protein to facilitate ubiquitination and subsequent degradation of that protein. While the field of targeted degraders is still relatively young, the potential for this modality to become a differentiated and therapeutic reality is strong, such that both academic and pharmaceutical institutions are now entering this interesting area of research. In this article, we describe a broadly applicable process for identifying degrader hits based on the serine/threonine kinase TANK-binding kinase 1 (TBK1) and have generalized the key structural elements associated with degradation activities. Compound 3i is a potent hit (TBK1 DC50 = 12 nM, Dmax = 96%) with excellent selectivity against a related kinase IKK?, which was further used as a chemical tool to assess TBK1 as a target in mutant K-Ras cancer cells.

Supramolecular polymers have shown to be powerful scaffolds for tissue engineering applications. Supramolecular biomaterials functionalized with ureidopyrimidinone (UPy) moieties, which dimerize via quadruple hydrogen-bond formation, are eminently suitable for this purpose. The conjugation of the UPy moiety to biologically active peptides ensures adequate integration into the supramolecular UPy polymer matrix. The structural complexity of UPy-peptide conjugates makes their synthesis challenging and until recently low yielding, thus restricted the access to structurally diverse derivatives. Here we report optimization studies of a convergent solid-phase based synthesis of UPy-modified peptides. The peptide moiety is synthesized using standard Fmoc solid-phase synthesis and the UPy fragment is introduced on the solid-phase simplifying the synthesis and purification of the final UPy-peptide conjugate. The convergent nature of the synthesis reduces the number of synthetic steps in the longest linear sequence compared to other synthetic approaches. We demonstrate the utility of the optimized route by synthesizing a diverse range of biologically active UPy-peptide bioconjugates in multimilligram scale for diverse biomaterial applications. 1 Introduction 2 Divergent Synthesis 3 Convergent Synthesis 4 UPy-Amine Strategy 5 UPy-Carboxylic Acid Strategy 6 Conclusion.

Multimeric cyclic RGD peptides as potential tools for tumor targeting: Solid-phase peptide synthesis and chemoselective oxime ligation

Thumshirn, Georgette,Hersel, Ulrich,Goodman, Simon L.,Kessler, Horst

, p. 2717 - 2725 (2007/10/03)

The αvβ3 integrin receptor plays an important role in human metastasis and tumor-induced angiogenesis. Targeting this receptor may provide information about the receptor status of the tumor and enable specific therapeutic planning. Solid-phase peptide synthesis of multimeric cyclo(-RGDfE-)-peptides is described, which offer the possibility of enhanced integrin targeting due to polyvalency effects. These peptides contain an aminooxy group for versatile chemoselective oxime ligation. Conjugation with para-trimethylstannylbenzaldehyde results in a precursor for radioiododestannylation, which would allow them to be used as potential tools for targeting and imaging αvβ3-expressing tumor cells. The conjugates were obtained in good yield without the need of a protection strategy and under mild conditions.
