A cyclophosphamide-resistant L1210 cell line has been shown to have unusually high aldehyde dehydrogenase activity. The sensitivity of this cell line to 4-methylcyclophosphamide and phosphoramide mustard in vivo and corresponding sensitivities in vitro indicate that 4-hydroxycyclophosphamide and/or aldophosphamide is the form in which cyclophosphamide reaches these tumor cells in mice and that ...
The ex vivo sensitivity of human multipotent and committed hematopoietic progenitor cells and several cultured human malignant blood cell lines to analogues of "activated" cyclophosphamide, namely, 4-hydroperoxycyclophosphamide and mafosfamide, and to phosphoramide mustard was quantified with and without concurrent exposure to an inhibitor of aldehyde dehydrogenase activity, namely, disulfiram,...
N-Butyl-phosphorotriamide (NBPT) is a fertilizer widely used for its urease inhibiting properties. Nevertheless, formulations currently commercialized are complex and do not avoid severe decrease of activity due to the low stability of the bioactive compound under acidic conditions. According to its structure, NPBT was thought to be able to interact with both polar additives, by its phosphorami...
methyl tetra - 0-methyl- ?-d- glucopyranoside is stereoselectively prepared from tetramethyl-d- glucopyranose by using (mei+nah) in toluene (86%) or cyclohexane (85%), while its ?- isomer is best synthesized in hexamethyl phosphoramide (64%). similarly, methyl tetra-o-methyl-?- d-mannopyranoside is synthesized in cyclohexane (80%), while its ?- isomer is predominantly prepared by (mei+n-buli) i...
