188891-13-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 188891-13-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,8,9 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 188891-13:
(8*1)+(7*8)+(6*8)+(5*8)+(4*9)+(3*1)+(2*1)+(1*3)=196
196 % 10 = 6
So 188891-13-6 is a valid CAS Registry Number.

UV-induced photolysis of polyurethanes

Petit, Charlotte,Bachmann, Julian,Michalek, Lukas,Catel, Yohann,Blasco, Eva,Blinco, James P.,Unterreiner, Andreas-N.,Barner-Kowollik, Christopher

supporting information, p. 2911 - 2914 (2021/03/24)

Waste production associated with the use of non-degradable materials in packaging is a growing cause of environmental concern, with the polyurethane (PU) class being notorious for their lack of degradability. Herein, we incorporate photosensitiveortho-Nitrobenzyl units into PUs to achieve controllable photodegradability. We performed their photolysis in solution and thin films which can inform the design of degradable adhesives.

Light Control of Protein Solubility Through Isoelectric Point Modulation

Nadendla, Karthik,Friedman, Simon H.

supporting information, p. 17861 - 17869 (2017/12/26)

We previously described the photoactivated depot or PAD approach that allows for the light control of therapeutic protein release. This approach relies on the ability to use light to change a protein's solubility. Traditionally this was accomplished by li

PHOTOCLEAVABLE DRUG CONJUGATES

-

Page/Page column 43, (2014/01/17)

Novel photocleavable drug conjugates for forming drug depots comprise drugs attached to photocleavable groups. In one embodiment, the drug is linked via photocleavable group(s) to a polymer chain to form a photocleavable drug-polymer conjugate that generally forms the depot matrix. In another embodiment, the drug is crosslinked via photocleavable group(s) to themselves to form a photocleavable drug conjugate that generally forms the depot.

Synthesis and properties of new photosensitive triazene and o-nitrobenzene methacrylates

Gaud, Vincent,Rougé, Fabien,Gnanou, Yves,Desvergne, Jean-Pierre

experimental part, p. 521 - 532 (2012/08/28)

New photoactive polymerizable monomers were synthesized in order to photomodulate the mechanical properties of photocurable materials. These monomers are end-capped by at least two polymerizable units (using irradiation wavelength λ1) connected by a spacer including at least one photocleavable unit (irradiation wavelength λ2 ≠ λ1) i.e. aryltriazene or 2-nitrobenzyl core. The photochemical behaviour of these systems was studied in solution and in resin formulations. Their ability to promote the hardening and crosslinking of a curable resin at λ1, then the subsequent degradation or modification of crosslinked resins under an actinic light (λ2) was evaluated by DMA for formulations including these new monomers. These new monomers were shown, in resin formulation, to readily rigidify the material upon λ1 irradiation and for most of them the subsequent photolysis of their internal linkers at λ2 irradiation was followed by a decrease of the hardness at low temperature (-20 °C). For one of them (compound 6) λ2 illumination at room temperature provoked the decrease of the mechanical properties of the solid material making it of interest for dental applications.

Patterning of gene expression using new photolabile groups applied to light activated RNAi

Jain, Piyush K.,Shah, Samit,Friedman, Simon H.

scheme or table, p. 440 - 446 (2011/04/15)

The spacing, timing, and amount of gene expression are crucial for a range of biological processes, including development. For this reason, there have been many attempts to bring gene expression under the control of light. We have previously shown that RN

Photo-induced release of active plasmid from crosslinked nanoparticles: O-nitrobenzyl/methacrylate functionalized polyethyleneimine

Model Studies for New o-Nitrobenzyl Photolabile Linkers: Substituent Effects on the Rates of Photochemical Cleavage

Holmes, Christopher P.

, p. 2370 - 2380 (2007/10/03)

Both a model phenacyl and o-nitrobenzyl photolabile linker from the literature along with four new o-nitrobenzyl linkers were prepared and the kinetics of their photolytic cleavage examined in solution. The linkers were prepared by amidation of the carboxylic acid anchoring tether with benzylamine, and the cleavable benzylic substituent was chosen to be either acetic acid or acetamide. Irradiation of the linkers in four solvents (methanol, p-dioxane, and aqueous buffer ± dithiothreitol) at 365 nm and analysis via HPLC afforded kinetic rates of cleavage suitable for comparative purposes. The phenacyl linker was found to cleave slowly under aqueous conditions with no detectable cleavage being observed in the organic solvents. Known o-nitrobenzyl linker 4 showed modest rates of cleavage in aqueous and organic solvents. Incorporation of two alkoxy groups in the benzene ring to generate the veratryl-based linker 13a increased the rate of cleavage dramatically, and introduction of an additional benzylic methyl group (13b) increased the rate of cleavage by an additional 5 fold. Increasing the length of the anchoring carboxylic acid tether from acetic to butyric acid (19) improved the cleavage kinetics modestly in organic media and slightly diminished the rates in water. The amide model linker 21 cleaved from 3 to 7 times faster than the corresponding ester linkage 19. An amide-generating linker 26 was prepared, and its performance to generate photolabile solid supports was briefly examined. The stability of the linker and subsequent cleavage upon photolysis from the support of an isotopically enriched 4-thiazolidinone was demonstrated by gel phase 13C NMR.
