Proton pump inhibitors
-
, (2008/06/13)
Novel thiadiazole compounds are provided, which are effective as proton pumps inhibitors, useful in treating peptic ulcers by inhibition of the proton pump enzyme H+/K+-ATPase. The compounds are 3-substituted 1,2,4-thiadiazolo [4,5- alpha ]benzimidazole and 3-substituted imidazo[1,2-d]-1,2,4-thiadiazoles corresponding to the general formula: where X and Z either represent an optionally substituted benzene ring fused to the diazole nucleus, or represent a variety of independent chemical groupings (hydrogen, lower alkyl, halo, etc.) and Y is selected from a wide range, e.g. heterocyclics and carbonyl groups.
Process for scavenging thiols
-
, (2008/06/13)
Thiols are trapped, and converted to disulfide compounds, by a process of reacting them with compounds containing a 1,2,4-thiadiazole ring structure carrying a substituent at position 3 of the thiadiazole ring, and being unsubstituted at position N-2. The process is useful pharmacologically, in inhibiting certain thiol-containing enzymes such as H+/K+-ATPase (the proton pump), and industrially, in selective removal of thiol compounds from gas or liquid mixtures.

The reactions of benzimidazothiadiazol-3(2H)-ones (1) with isocyanates, isothiocyanates, carbon disulphide, aryl cyanates, acetylenedicarboxylates, and enamines, with exchange of the isocyanate component of (1), to give the corresponding condensed benzimidazole derivatives (1)-(6) are described.Under more severe conditions the 1-benzothiazol-2-yl-1,3-dihydrobenzimidazole-2-thiones (7) were obtained from aromatic isothiocyanates.Thermolysis of the thiadiazoles (1) led to the triazine derivative (12) with elimination of isocyanate and sulphur, and in the presence of phenols to the 2-aryloxybenzimidazoles (13).With amines and CH-acidic compounds, the S,N bond in compound (1) was cleaved to give benzimidazol-2-ylsulphenamides (14), and the ω-substituted methylthiobenzimidazoles (17) and (18).With cyanide ion, insertion into the S,N bond of compound (1) to furnish the thiadiazine (22) took place.The dithiazoles (2) were fragmented by amines to give 1,3-dihydrobenzimidazole-2-thione and guanidine with loss of sulphur; reaction with cyanide ion then gave the dibenzimidazothiadiazine (25).

The addition products of benzimidazolinethione and isocyanates are easily cyclized to benzimidazolo(1,2,4)thiadiazoline systems 4 by treatment with Br2/NEt3.The thio-analogues 9 were synthesized from 2-aminophenyl thioureas and thiophosgene followe
