Phenoxazines
WebInterests in synthetic phenoxazines stem from the first isolation of Actinomycin D by Waksman and coworkers in 1940, which was then found to possess significant antibiotic and antineoplastic activities. Recently, arrays of phenoxazines with diverse pharmacological properties such as anti-malarial, anticancer, antiviral, antidiabetic, anti ... WebThe novel 2-trifluoromethylphenoxazine (1) was prepared by the pyrolytic condensation of 2-bromophenol and 4-chloro-3-nitrobenzotrifluoride as outlined in Scheme-I. This compound undergoes N-alkylation in the presence of phase transfer catalyst (PTC).

WebThe mass spectral behavior of a set of eight 2‐ and 10‐disubstituted phenoxazines putatively possessing anticancer drug enhancer properties was investigated. Both electron ionization (EI) and keV‐ion beam bombardment (liquid secondary ion mass spectrometry, LSIMS) were used. As expected, EI led to extensive fragmentation to produce ... WebSep 22, 2024 · Thus, phenoxazines with comparable oxidative stability to commonly used diphenylamine and phenothiazine RTAs had significantly greater reactivity (by up to 2 orders of magnitude). Computations suggest that this remarkable balance in H-atom transfer kinetics and stability to one-electron oxidation results from the ability of the bridging …
