THP-PEG5 is a PEG (polyethylene glycol) linker that features a THP (tetrahydropyranyl) protecting group and a terminal hydroxyl group. The THP group is an acid-labile, alcohol protecting group, which means it can be removed under acidic conditions, revealing the alcohol functionality. The terminal hydroxyl group allows for further chemical modifications and derivatization of the compound. The presence of hydrophilic PEG linkers enhances the water solubility of THP-PEG5 in aqueous media, making it a versatile molecule for various applications.

128660-97-9 Usage

Uses

Used in Pharmaceutical Industry:
THP-PEG5 is used as a protecting group for alcohols in the synthesis of complex organic molecules, particularly in the pharmaceutical industry. The acid-labile nature of the THP group allows for selective deprotection under acidic conditions, enabling the controlled release of active pharmaceutical ingredients.
Used in Drug Delivery Systems:
THP-PEG5 is used as a component in the design and development of drug delivery systems. The hydrophilic PEG linkers improve the solubility and stability of drug molecules in aqueous environments, while the terminal hydroxyl group allows for the attachment of drug molecules or other functional groups. This enhances the bioavailability and targeted delivery of therapeutic agents.
Used in Chemical Synthesis:
THP-PEG5 is used as an intermediate in the synthesis of various chemical compounds, particularly those requiring a hydroxyl group for further functionalization. The acid-labile THP group provides a means to control the reactivity and selectivity of the molecule during the synthesis process.
Used in Bioconjugation:
THP-PEG5 is used as a bioconjugation agent, facilitating the attachment of biologically active molecules, such as proteins, peptides, or nucleic acids, to other molecules or surfaces. The hydroxyl group can be used to form covalent bonds with the target biomolecule, while the PEG linker provides a hydrophilic spacer to reduce non-specific interactions and increase solubility.
Used in Material Science:
THP-PEG5 can be used in the development of novel materials with enhanced properties, such as improved water solubility, increased stability, or tailored reactivity. The PEG linker and terminal hydroxyl group can be incorporated into polymers, dendrimers, or other macromolecular structures to achieve specific material characteristics.

Check Digit Verification of cas no

The CAS Registry Mumber 128660-97-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,6,6 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 128660-97:
(8*1)+(7*2)+(6*8)+(5*6)+(4*6)+(3*0)+(2*9)+(1*7)=149
149 % 10 = 9
So 128660-97-9 is a valid CAS Registry Number.

Photochemical fabrication of three-dimensional micro- and nano-structured surfaces from a C60 monoadduct

Iqbal, Parvez,Sun, Shuqing,Hanwell, Marcus D.,Attwood, David,Leggett, Graham J.,Preece, Jon A.,Richardson, Tim H.,Tunnicliffe, David

, p. 2016 - 2021 (2008)

Exposure of Langmuir-Blodgett (LB) films of a C60 adduct supported on silicon wafers to UV light leads to cross-linking of the C 60 moieties, which are resistant to removal by solvent exposure, whereas unexposed moieties are readily removed. This process provides a convenient and simple route for the fabrication of highly conjugated surface-attached structures, with dimensions ranging from micrometres (using masks) to a few tens of nanometres using light emitted from a scanning near-field optical microscope (SNOM). The SNOM writing velocity was found to significantly affect the lateral resolution and the height of the three-dimensional nanostructures. Increasing the writing velocity from 0.3 to 2 μm s-1 resulted in a decrease in the width of the structures from 240 nm to 70 nm (corresponding to the SNOM aperture diameter), respectively, and a reduction in the height from 8 nm (the thickness of the original film) to 3 nm, respectively. This approach provides a simple, direct route to surface-bound nanometre scale assemblies of C60.

Preparation of 7-methoxy tacrine dimer analogs and their in vitro/in silico evaluation as potential cholinesterase inhibitors

, p. 1654 - 1660 (2015)

Novel types of symmetric bis-7-methoxytacrines connected by oligoethyleneoxy chains 3-5 and nonsymmetric monomeric 7-methoxytacrines containing hydroxyl-terminated oligoethyleneoxy chains 6-8 were prepared, and their in vitro/in silico effects on human recombinant AChE (hAChE) and human plasmatic butyrylcholinesterase (hBChE) were compared, with 7-MEOTA (2) as the standard compound. The symmetric bis-7-MEOTA derivatives 3-5 showed hAChE inhibition similar to that of 2. On the other hand, their effects on hBChE revealed an increasing inhibition trend when the oligoethyleneoxy units between the two 7-MEOTA moieties became longer. Accordingly, compounds 4 and 5 showed better selectivity towards hBChE. The most effective in the inhibition hAChE and hBChE was compound 8 with the longest oligoethyleneglycol chain, whereas compounds 6 and 7 resulted in similar IC50 values. A molecular modeling study using substrates 5 and 8 showed a possible binding conformation and protein-ligand interaction between the substrates and AChE/BChE.

Synthesis of a library of propargylated and PEGylated α-hydroxy acids toward "clickable" polylactides via hydrolysis of cyanohydrin derivatives

Zhang, Quanxuan,Ren, Hong,Baker, Gregory L.

, p. 9546 - 9555 (2015/02/19)

A new simple and practical protocol for scalable synthesis of a novel library of propargylated and PEGylated α-hydroxy acids toward the preparation of "clickable" polylactides was described. The overall synthesis starting from readily available propargyl alcohol, bromoacetaldehyde diethyl acetal, and OEGs or PEGs was developed as a convenient procedure with low cost and no need of column chromatographic purification. The terminal alkyne functionality survives from hydrolysis of the corresponding easily accessible cyanohydrin derivatives in methanolic sulfuric acid. Facile desymmetrization, monofunctionalization, and efficient chain-elongation coupling of OEGs further enable the incorporation of OEGs to α-hydroxy acids in a simple and efficient manner. At the end, synthesis of allyloxy lactic acid indicates that an alkene group is also compatible with the developed method. (Chemical Equation Presented).
