The spin labeled analog of Thio-Tepa, l-oxyl-2,2,6,6-tetramethyl-4-piperidylN,N;N',N'-bis (ethylene )-phosphorodiamidothioate (SL-O-TT), which contains a nitroxyl free radical linked by an oxygen bridge to phosphorus, has antitumor properties against P388 murine leukemia (T/C = 242) and a higher therapeutic ratio (5.15) than its parent compound, Thio-TEPA (2.75). The drug is less toxic to P388 ...

Biochar-based carbonaceous adsorbents are gaining interest due to their high availability, ease of modification, and low cost; however, they show limited adsorption CO2 in flue gas common textural properties. In this study, TEPA-modified biochar was used prepare a solid amine adsorbent for the efficient capture gas. First, porous prepared with FeCl3, Mg(NO3)2, H2O (g) as activators walnut shell...

In recent years, a considerable amount of work has been done in order to elucidate the role of free radical intermediates in carcinogenesis 3. Particular­ ly, with the EPR technique a series of interesting but controversial results have been obtained 3. As a con­ sequence, to date, no conclusions can be made con­ cerning the role of free radicals and other paramagnetig species during the induct...

Amine based adsorbents are promising options for CO2 removal from industrial exhaust streams because they offer low regeneration energy and high capture performance. Tetraethylenepentamine (TEPA) is one of the most common commercial polyamines that has been used as a prototypical amine to develop effective capture. For viability carbon on adsorbents, durability sites during practical applicatio...
