Unsaturated hydroxyalkylquinoline acids as leukotriene antagonists
-
, (2008/06/13)
Compounds having the formula I: STR1 are leukotriene antagonists and inhibitors of leukotriene biosynthesis. These compounds are useful as anti-asthmatic, anti-allergic, anti-inflammatory, and cytoprotective agents. They are also useful in treating angina, cerebral spasm, glomerular nephritis, hepatitis, endotoxemia, uveitis, and allograft rejection.

In order to search for anti-hepatitis drugs, we synthesized a series of eight- and nine-membered cyclic disulfides (1) and six- and seven-membered cyclic sulfides (2) and evaluated them for ability to reduce mortality in the model of acute hepatic failure
Synthetic Approaches towards the Novel 1,3-Dioxo-1,2-dithiolane Moiety in the Antitumour Antibiotic Substance Leinamycin

A number of complementary synthetic approaches to the β-thiolactone intermediate 9 for elaboration to the novel 1,3-dioxo-1,2-dithiolane moiety 6 found in the antitumour antibiotic substance leinamycin 1 are described.Thus, deprotection of the benzylthio ether produced from 3-methylbut-2-enoic acid and toluene-α-thiol, leads to the mercapto acid 12 which on cyclisation produces the thiolactone 13. α-Methylation of the thiolactone 13, followed by α-oxygenation then gives rise to the substituted β-thiolactone 9.The β-thiolactone 9 is also produced when: (i) thesodium glycidate 17 is stirred with sodium sulfide leading to 18, followed by thiolactonisation; (ii) thioacetone is treated with the ketene derived from 2-acetoxypropanoyl chloride; and (iii) by irradiation of 3-methyl-2-trimethylsilyloxybut-2-ene 22 with thiophosgene leading to 23, followed by hydrolysis.The β-thiolactone 9 is then converted in three steps into the 1,3-dioxo-1,2-dithiolane 6 by: (i) ring opening to the thioic acid 15, using hydrogen sulfide-triethylamine; (ii) ring closure of 15 to 8 in the presence of aqueous ferric chloride; and finally (iii) oxidation using dimethyldioxirane.Treatment of the ethyl glycidate 19 with disodium disulfide in hot ethanol for 3 days provides the 1,2-dithiolane 8 directly, but in low yields (11-15percent).When the aforementioned reaction sequences are translated to the glycidate 24, derived from 4-methylcyclohex-3-enone and α-chloropropanoic acid, the syntheses of the key intermediates 25, 27 and 26 en route to the spiro-fused 1,3-dioxo-1,2-dithiolane 7 and leinamycin 1 (see Scheme 1) were secured.
