Mass Spectrometry Profiling of the Protein Composition of Blood Plasma of Colorectal Cancer Patients

The objective of the study is themass spectrometry analysis of the protein composition in blood plasma samples of large intestine cancer patients. Protein profiles of 58 blood plasma samples of large intestine cancer patients and healthy volunteers are analyzed using ultrahigh-resolution panoramic mass spectrometry. It is shown that the coincidence of identifications in the protein composition samples of intestine cancer patients and healthy men is 60–80%. Samples of intestines cancer patients contain proteins involved in the interaction with ribonucleic acid, proteins, and lowmolecular substrata.

Radical intermediates in hydrogenation of aromatic nitro compounds in presence of platinum(ii) complex with alizarin

Conclusions The particles, obtained by the reduction of the Pt(II)-alizarin complex with H₂ and subsequent reaction with sym-trinitrobenzene, have a radical nature.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 4, pp. 924–925, April, 1981.     

EPR spectra and structure of 1,2-dihydroxy- and 1,2,4-trihydroxy-anthrasemiquinones

Conclusions Radicals of hydroxyanthrasemiquinones were generated by chemical and electrochemical reduction and their probable structures established by EPR.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 4, pp. 822–827, April, 1986.     

Radical intermediates in the electrochemical reduction of alizarin

Conclusions In the electroreduction of alizarin in an aprotic medium the stepwise formation of the anion-radical and subsequently of the dianion has been observed; under conditions of the prolonged process the anion-radical disproportionates and through intermediate stages of deprotonation and reduction is converted into the stable dianion-radical.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 5, pp. 983–988, May, 1985.     

Photoinduced reactions of organic compounds with transition metal complexes: II. Reaction of PtCl62− with acetone to give a σ-acetonyl complex of platinum(IV). Detection of platinum(III) compounds by ESR

Light irradiation of a PtCl₆^2? solution in acetone affords a σ-acetonyl complex of platinum(IV), [CH₃COCH₂PtCl₅]^2?. Prolonged irradiation yields CH₃COCH₂Cl and PtCl₄^2?. The signals of a platinum(III) complex and CH₃COCH₂^. are detected in the ESR spectrum of the frozen solution of PtCl₆^2? in acetone irradiated at 77 K. The proposed mechanism of the reaction involves electron transfer from the enol tautomer of acetone to PtCl₆^2?.
