Abstract:
A composition of bibenzimidazoles of the Formula (I) :
wherein X&Y which may be the same or different and, taken together, contain a total of from 12 to 52 saturated carbon atoms, are (a) each selected from -R, -COR, -CH 2 COOR, -CH(COOR) 2 and -COOR; or (b) together form a group selected from
and
wherein R is an optionally substituted hydrocarbyl group, A & B taken together with the two carbon atoms to which they are linked form an optionally substituted benzene ring ; and C & D taken together with the two carbon atoms to which they are linked form an optionally substituted benzene ring ; characterised in that at least 50% by weight of the bibenzimidazoles in the composition are of Formula (II) wherein X and Y are as hereinbefore defined ; T, U, V & W which may be the same or different, are H, R 1 or OR 1 provided at least one of T, U, V & W is R 1 or OR 1 ; and R 1 is C 1-6 -alkyl ; which are suitable for use in the extraction of zinc from aqueous solutions of zinc in the presence of other metals.
Abstract:
Methods and computer systems are described herein for identifying small molecules that bind to selected RNA structural features (e.g., to RNA secondary structures). Also described are compounds and compositions that modulate RNA function and/or activity.
Abstract:
A stable 2,2'-bibenzo[d]imidazolidene compound is provided. The 2,2'-bibenzo[d]imidazolidene compound is expressed by the following General Formula (1). In General Formula (1), Ar1 to Ar8 each represent a substituted or unsubstituted condensed ring. R1 to R8 each represent a hydrogen atom or a substituent.
Abstract:
A bibenzo[d]imidazolidene compound inert to oxygen is provided. An aspect of the invention provides a 1,1',3,3'-tetraphenyl-2,2'-bibenzo[d]imidazolidene compound according to Claim 1, which is represented by general formula (1). In formula (1), R1 to R28 are each independently selected from a hydrogen atom and a substituent. The substituent is any of a halogen atom, an alkyl group containing 1 or more and 8 or less carbon atoms, and a substituted or unsubstituted aryl group. At least one of R1 to R28 is the substituent.
Abstract:
The present invention is concerned with novel 4-substituted 1,3-dihydro-2H- benzimidazol-2-one derivatives substituted with benzimidazoles having formula (I), tautomers and stereoisomeric forms thereof, and the pharmaceutically acceptable addition salts, and the solvates thereof, wherein R 4 , R 5 , Z and Het have the meaning defined in the claims. The compounds according to the present invention are useful as inhibitors on the replication of the respiratory syncytial virus (RSV). The invention further concerns the preparation of such novel compounds, compositions comprising these compounds, and the compounds for use in the treatment of respiratory syncytial virus infection.
