Reaction of disodium cromoglycate with hydrated electrons

Reactivity of chloroethyl sulfides in the presence of a chlorinated prophylactic: a kinetic study by EPR/spin trapping and NMR techniques†**

“…The intensity of the EPR spectra obtained from the resulting spin adducts is sensitive to the rate at which the spin adducts is formed. 7,8 Because S-330 reacts 55 times faster than PBN, the results obtained for S-330 indicate that S-330 9 (Fig. 6) 9 is an efficient ؒ SO 2 RЈ S12 C.

Autoionization reaction of phosgene (OCC12) studied by electron paramagnetic resonance/spin trapping techniques

“…The addition of phosgene to a DMPO solution generated two spin adducts: a triplet of doublets with hyperfine structure, uN = 1.598 mT and uH = 2.273 mT, in addition to the typical DMPO-H adduct (7) with hyperfine coupling constants, ffN = 1.66 mT and &(2) = 2.254 mT. The DMPO-H contribution to the overall EPR spectrum is less than 5%; however, since this adduct is short-lived (flj2 < 1 min), its contribution to the overall EPR spectrum may not accurately reflect the actual amount formed.…”

Effects of aminoguanidine on pre- and post-irradiation regional cerebral blood flow, systemic blood pressure and plasma histamine levels in the primate

“…Radiation-induced release of free radicals also influences mast cell degranulation [33,34]. However, the administration of disodium cromoglycate [15], an efficient hydrated electron scavenger [35], did not decrease the radiation-induced release of HA in nonhuman primates. This experiment showed that pretreatment of primates with the DAO inhibitor, AG, altered the postirradiation levels of plasma HA and the hypotensive response to radiation, but did not alter postirradiation rCBF response.…”
