The Chemotherapy of Sulphon-Amides.
THE chemotherapy of bacterial diseases is a medical innovation of the last four years only. In the case of the protozoal infections, on the other hand, this form of treatment is comparatively ancient. The discovery of the effect of quinine in malaria dates from the seventeenth century, and mercury was used in syphilis in very early times. In I9IO Ehrlich and Hata published the discovery of the ...
متن کاملThe fate of certain organic acids and amides in the rabbit; nitrobenzoic acids and amides.
Studies in vitro (Bray, James, Ryman & Thorpe, 1948a) have shown that rabbit-liver extracts are able to hydrolyze all three nitrobenzamides. The para isomer is most readily attacked, the average hydrolysis being 82 %; under the same conditions the meta and ortho isomers are hydrolyzed to the extent of 31 and 23 %, respectively. It was, therefore, of interest to study the metabolism of these com...
متن کاملOzonization at the vacancy defect site of the single-walled carbon nanotube.
The ozonization at the vacancy defect site of the single-walled carbon nanotube has been studied by static quantum mechanics and atom-centered density matrix propagation based ab initio molecular dynamics within a two-layered ONIOM approach. Among five different reaction pathways at the vacancy defect, the reaction involving the unsaturated active carbon atom is the most probable pathway, where...
متن کاملStructural and Gas Retention Changes Induced by Ozonization of Cobalt(II) and Manganese(II) Hexacyanocobaltates(III)
Transition metal hexacyanocobaltates are porous materials with open metal sites and a wide variety of pores. In this work, manganese(II) and cobalt(II) hexacyanocobaltates(III) have been selected to explore the interactions between the open metal sites located in their pores and the guest molecules: hydrogen, carbon dioxide, water and methanol. An experimental setup was designed and implemented...
متن کاملAmides and Related Functional Groups
Recall that nitrogen has five valence electrons and therefore requires three electrons or bonds to complete its octet (see Amine Tutorial). Based on this valence and bonding order, nitrogen forms three bonds in its neutral state and maintains one pair of non-bonded electrons (NBEs). In amides one of the three bonds is a carbonyl carbon. Thus amides may be viewed as "acylated amines" or as deriv...
