-
Page/Page column 19, (2018/09/21)
The present disclosure generally relates to ionic compositions which may be used in or as an adhesive material for selectively adhering two items together. More particularly, but not exclusively, the present disclosure relates to ionic compositions that include a cationic imidazolium compound and an anionic compound such as a sulfonyl imide compound.
Halogen bond anion templated assembly of an imidazolium pseudorotaxane

supporting information; experimental part, p. 5322 - 5326 (2010/10/19)
Halogen bonding has been exploited in the assembly of an interpenetrated molecular system. The strength of chloride-anion-templated pseudorotaxane formation with a 2-bromo-functionalized imidazolium threading component and an isophthalamide macrocycle (see picture) is significantly enhanced compared to hydrogen-bonded pseudorotaxane analogues.

, p. 2715 - 2720 (2007/10/02)
A novel structural class of highly potent and selective 5-HT3 receptor antagonists is described.The compounds in this new series contain a thiazole moiety linking an aromatic group and a nitrogen-containing basic region; the thiazole group appears to be acting as a carbonyl bioisostere in this system.An optimized member of this series, 4-(2-methoxyphenyl)-2-methyl>thiazole (5), exhibits oral activity in the Bezold-Jarisch reflex paradigm comparable to or better than the standard agents ondansetron (1) and ICS-205-930 (2).Several of the structure-activity relationships are rationalized in terms of a computer pharmacophore model for 5-HT3 receptor binding.

4-(2-Methoxyphenyl)-2-[4(5)-methyl-5(4)-imidazolylmethyl]thiazole (5) is a highly potent member of a structurally novel series of selective serotonin-3 receptor antagonists. The synthesis of tritriated 5 and its binding profile in neuroblastoma-glioma 108
Photographic reagent tetrazoles
-
, (2008/06/13)
There are described novel photographic products and processes which utilize compounds which release a photographic reagent in the presence of alkali. The compounds include an imidazole blocking group and cleave in alkali to release the photographic reagent. Also described are novel compounds.
Conformationally restricted histamine H2 -receptor antagonists containing a tropane ring
-
, (2008/06/13)
Histamine H2 -receptor antagonists having the formula STR1 wherein R1 represents C1 -C4 alkyl or benzyl, R2 represents hydrogen or C1 -C4 alkyl, and Het represents an imidazole, pyrazole, pyrimidine, pyrazine, pyridazine, thiazole, isothiazole, oxazole, isoxazole, triazole, thiadiazole, benzimidazole, or furan ring either unsubstituted or substituted with a C1 -C4 alkyl, hydroxyl, trifluoromethyl, benzyl, halogen, amino, or dimethylaminomethyl group are disclosed along with a synthetic method of producing such compounds and their use as gastric-acid-production inhibitors.
Synthesis of cimetidine

, p. 688 - 690 (2007/10/02)
A simple and economical synthesis of cimetidine is described. It is based on the reaction of 4-halomethyl-5-methylimidazole with N-cyano-N'-methyl-N''-(2 mercaptoethyl)guanidine in water-ethanol at pH 9.0 ± 0.3. Pure crystalline cimetidine is obtained in about 75% yield.
Preparation of 4-methyl-5-chloromethyl-imidazole
-
, (2008/06/13)
4-Methyl-5-chloromethyl-imidazole is prepared in the form of its hydrochloride by direct chloromethylation of 4-methyl-imidazole, thus becoming readily available industrially as an intermediate.
