Design, synthesis and activity against human cytomegalovirus of non-phosphorylatable analogs of toyocamycin, sangivamycin and thiosangivamycin
(Elsevier, 1992-12)
A number of 7-alkyl 4-aminopyrrolo[2,3-pyrimidine derivatives related to toyocamycin, sangivamycin and thiosangivamycin have been prepared and tested for their activity against human cytomegalovirus (HCMV). Only the thioamide ...
Phase II trial of N-methylformamide in lung cancer
(Kluwer Academic Publishers; Springer Science+Business Media, 1992-08)
The effect of 2,2'-dichlorodiethyl sulfide on DNA synthesis of a murine stratified keratinocyte culture system
(Elsevier, 1992-09-28)
A primary stratified keratinocyte culture resembling the epidermis in situ was used as a model for studying the effects of exposure to 2,2'-dichlorodiethyl sulfide, or sulfur mustard (SM), on DNA synthesis. A method that ...
Comparison of heat capacities measured by adiabatic calorimetry and by scanning calorimetry: thermodynamic properties of 9-methylcarbazole at temperatures between 4 K and 345 K
(Elsevier, 1992-03)
We have measured the heat capacity of 9-methylcarbazole at 4[less-than-or-equals, slant]T/K[less-than-or-equals, slant]345 by adiabatic calorimetry and compared it with that measured by differential scanning calorimetry ...
The thermochemical and thermophysical properties of Cs2RuO4 and Cs2MnO4 at temperatures from 5 K to 1000 K
(Elsevier, 1992-08)
Low-temperature heat capacities from 5 K to 350 K by adiabatic calorimetry and high-temperature enthalpy increments above T = 450 K to 800 K by drop calorimetry of Cs2RuO4 and Cs2MnO4 have been measured. The two compounds ...
Effect of calcium chloride treatment on hybridoma cell viability and growth
(Kluwer Academic Publishers; Springer Science+Business Media, 1992-10)
In order to minimize hybridoma cell damage during calcium alginate entrapment, the effect of calcium chloride treatment on hybridoma cell viability and growth was studied in terms of calcium chloride concentration and ...
A model of glucocorticoid receptor unfolding and stabilization by a heat shock protein complex
(Elsevier, 1992-03)
It has recently been reported that incubation of avian progesterone receptors, mouse glucocorticoid receptors, or the viral tyrosine kinase pp60src with rabbit reticulocyte lysate reconstitutes their association with the ...
Hydrogenolysis of adsorbed methylthiolate on the Pt(111) surface
(Elsevier, 1992-11-01)
A combination of temperature programmed reaction experiments and fluorescence yield near edge spectroscopy (FYNES) has been used to characterize hydrogen induced C-S bond activation in adsorbed methylthiolate on the Pt(111) ...
The use of sulfide cluster-derived catalysts to understand the promotional effect in hydrotreatment catalysis
(John Wiley & Sons Ltd., 1992-09)
Sulfide cluster-derived ensembles are promising models of the active sites in commercial hydrotreatment catalysts. A series of sulfide clusters were adsorbed intact onto high-surface-area Γ-alumina, magnesium oxide and ...
