- Ionic liquid used for secondary battery, synthetic method and application
-
The invention provides an ionic liquid used for a secondary battery, a synthetic method and application. The ionic liquid used for the secondary battery is an ionic liquid containing a heteroatom sidechain, and a functional group with positive charges inside the ionic liquid is one of quaternary ammonium salt, imidazolium salt, pyrrole salt and pyridinium salt; Y inside the side chain is S, an alkyl chain with the length of C1 to C3 is arranged between Y and the functional group with the positive charges, and alcohol or benzyl of C1 to C3 is arranged on the side, away from the functional group with the positive charges, of Y; and a negative ion X- is one of Cl-, Br-, I-, BF4- and TFSI- (trifluoromethanesulfonimide). The structure adjustability of the ionic liquid is preferable, the chemical structure of the ionic liquid can be modulated through a substituent group according to requirements, the conductivity of the ionic liquid is more than 1 mS/cm, and the requirement of the novel secondary magnesium battery on the conductivity can be met; sulfydryl is introduced into the ionic liquid by adopting nucleophilic substitution, and the complex capacity of the synthetic ionic liquid containing the heteroatom side chain on magnesium is theoretically moderate, so that the cycle performance of the battery is preferable.

- 16-Ethers of fusidic acid derivatives
-
The present invention relates to a new series of fusidic acid derivatives, to salts and easily hydrolysable esters thereof, to the preparation of these compounds, and to pharmaceutical compositions containing the compounds. The new compounds have the general formula STR1 in which the C24-25 bond is a single or a double bond, and in which Q1 and Q2 stand for STR2 or oxygen; A stands for oxygen, sulphur or a sulfinyl radical; R1 stands for a straight or branched alkyl radical having from 1 to 8 carbon atoms, an alkenyl or alkynyl radical having from 2 to 6 carbon atoms, a cycloalkyl radical having from 3 to 7 carbon atoms in the alicyclic ring, an aryl or aralkyl radical, a heterocyclic radical having 5 or 6 ring atoms, and containing oxygen, sulphur or nitrogen atoms, and pharmaceutically acceptable salts and easily hydrolysable esters thereof. The compound of the present invention show interesting antimicrobial and pharmacokinetic properties. Thereby the compounds of the invention can be used in the treatment of bacterial infections in humans and animals.
