In the field of bioconjugation, m-PEG11-Tos is used as a coupling agent to attach biomolecules, such as peptides, proteins, or nucleic acids, to other molecules or surfaces. The PEG spacer provides a hydrophilic environment that reduces aggregation and improves stability, while the tosyl group facilitates the coupling reaction.
Used in Drug Delivery Systems:
Polyethylene glycol monomethyl ether tosylate is used as a component in drug delivery systems to improve the solubility, stability, and bioavailability of therapeutic agents. The PEG spacer can help to reduce the immunogenicity and non-specific interactions of the drug, while the tosyl group can be used for the attachment of drugs or targeting moieties.
Used in Surface Modification:
In the industry of surface modification, m-PEG11-Tos is used as a surface-active agent to introduce hydrophilic and biocompatible properties to various materials. The PEG spacer can provide a stable and resistant coating, while the tosyl group can be used for further functionalization or attachment of specific molecules to the surface.

Check Digit Verification of cas no

The CAS Registry Mumber 58320-73-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,3,2 and 0 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 58320-73:
(7*5)+(6*8)+(5*3)+(4*2)+(3*0)+(2*7)+(1*3)=123
123 % 10 = 3
So 58320-73-3 is a valid CAS Registry Number.

Post-modification of helical dipeptido polyisocyanides using the 'click' reaction

Chirality Synchronization of Hydrogen-Bonded Complexes of Achiral N-Heterocycles

Buchs, Jens,Vogel, Laura,Janietz, Dietmar,Prehm, Marko,Tschierske, Carsten

, p. 280 - 284 (2017)

2,4-Diamino-6-phenyl-1,3,5-triazines carrying a single oligo(ethylene oxide) (EO) chain form an optically isotropic mesophase composed of a conglomerate of macroscopic chiral domains with opposite sense of chirality even though the constituent molecules are achiral. This mesophase was proposed to result from the helical packing of hydrogen-bonded triazine aggregates, providing long-range chirality synchronization. The results provide first evidence for macroscopic achiral symmetry breaking upon conglomerate formation in an amorphous isotropic phase formed by hydrogen-bonded associates of simple N-heterocycles that are related to prebiotic molecules.

CD4 mimics are small molecules that inhibit the interaction of gp120 with CD4. We have developed several CD4 mimics. Herein, hybrid molecules consisting of CD4 mimics with a long alkyl chain or a PEG unit attached through a self-cleavable linker were synthesized. In anti-HIV activity, modification with a PEG unit appeared to be more suitable than modification with a long alkyl chain. Thus, hybrid molecules of CD4 mimics, with PEG units attached through an uncleavable linker, were developed and showed high anti-HIV activity and low cytotoxicity. In investigation of pharmacokinetics in a rhesus macaque, a hybrid compound had a more effective PK profile than that of the parent compound, and intramuscular injection was a more useful administration route to maintain the high blood concentration of the CD4 mimic than intravenous injection. The presented hybrid molecules of CD4 mimics with a PEG unit would be practically useful when combined with a neutralizing antibody.
