Development of a new photosafety test method based on singlet oxygen generation detected using electron spin resonance

Photosafety evaluations of chemicals used in consumer products, such as pharmaceuticals and cosmetics, are very important. Currently, two non-animal tests for photosafety evaluations, the in vitro 3T3 neutral red uptake phototoxicity test (NRU PT) and the reactive oxygen species (ROS) assay, are used to detect photoreactive chemicals. However, these two tests are difficult to apply to hydrophobic chemicals. In the present study, we attempted to develop a new photosafety test method, named the electron spin resonance-based photosafety test (ESR-PT), that would be applicable even to hydrophobic chemicals based on the detection of singlet oxygen generation after irradiation using ESR spectroscopy with 4-hydroxy-2,2,6,6-tetramethyl-piperidine as a spin trap reagent. To achieve a quantitative evaluation, the singlet oxygen formation (SOF) value, which can be calculated as the increment in relative intensity after irradiation of the test mixture normalized by the increment in relative intensity after irradiation of the vehicle control solution, was calculated. The performance of the ESR-PT was evaluated by testing all the proficiency chemicals of the ROS assay plus additional chemicals, including hydrophobic chemicals and chemicals that tested false negative in the 3T3-NRU PT and ROS assay. SOF values were successfully calculated for all the chemicals tested including the hydrophobic chemicals, and the accuracy of the ESR-PT using a tentative cutoff value of 2.8 against the photosafety information was 100%. Therefore, the SOF value could be an effective parameter for photosafety evaluations, suggesting that the newly developed ESR-PT is a promising non-animal test applicable even to hydrophobic chemicals.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 388077-74-5, in my other articles.

Constructing micro-phase separation structure to improve the performance of anion-exchange membrane based on poly(aryl piperidinium) cross-linked membranes

The ether-bond-free poly(biphenyl piperidine)s are prepared to improve the alkaline stability of the anion exchange membrane (AEMs). At the same time, the construction of micro-phase separation structure is a good way to solve the trade-off’ problem between ionic conductivity and stability of AEMs. In this study, we report a new method for constructing micro-phase separation structures based on main-chain type AEMs and a crosslinking strategy that does not sacrifice ion exchange capacity. A series of poly(biphenyl piperidine)s AEMs (PAP-OH-x) are prepared by introducing 2-bromoethanol and 1,6-dibromohexane to form piperidine cationic groups and cross-linked structure. The structure of hydrophilic/hydrophobic phase separation is confirmed by TEM images. The cross-linked membrane of poly(biphenyl piperidine)s (PAP-OH-8%) membrane exhibits high conductivity of 0.081 S/cm with a rational water absorption (55.6%) and low swelling ratio (11.8%) at 80 degrees C, and also preserves the hydroxide conductivity (89.2% retention) after testing in a 5 M NaOH aqueous solution at 80 degrees C for 30 days, exhibits high alkaline stability. Furthermore, a single H-2/O-2 fuel cell with poly(biphenyl piperidine)s (PAP-OH-8%) membrane exhibits the open circuit voltage of 1.02 V and the peak power density of 290 mW/cm(2) at 60 degrees C.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 388077-74-5, you can contact me at any time and look forward to more communication. HPLC of Formula: C11H20N2O3.
