identified as potent inhibitors of 5-lipoxygenase in vitro exhibiting IC50's of less than 1 microM. An investigation of structure-activity relationships showed that the most potent inhibitors of this series are the 5-phenyl derivatives. The corresponding thiazolidin-4-one analogues were found to be relatively inactive. The 4-hydroxythiazoles were active inhibitors against 5-lipoxygenase in both intact rat

Histamine H3 receptor (H3R) is largely expressed in the CNS and modulation of the H3R function can affect histaminesynthesis and liberation, and modulate the release of many other neurotransmitters. Targeting H3R with antagonists/inverse agonists may have therapeutic applications in neurodegenerative disorders, gastrointestinal and inflammatory diseases. This prompted us to design and synthesize azole-based
Catalytic Enantioselective Synthesis of Tertiary Thiols From 5<i>H</i>-Thiazol-4-ones and Nitroolefins: Bifunctional Ureidopeptide-Based Brønsted Base Catalysis
Fully loaded: The ureidopeptide‐basedbifunctionalBrønstedbase 1 efficiently promotes the first direct catalytic Michael reaction of α‐mercapto carboxylate surrogates with nitroolefins involving a fully substituted α‐carbon atom construction.

heteroatom. In addition, several related examples, having additional nuclear substituents and/or groups other than CN in the position adjacent to the aminohydroxypropoxy group, were prepared, and beta-adrenoceptor antagonist activity and vasodilating potency were determined. Three compounds, thiazole 2 and isothiazoles 3 and 27, effectively lowered mean arterial pressure in the SH rat at 5 mg/kg. Compounds
The reaction of thioamides (1) with various haloacyl halides (2, 7, 11, 14, 17, and 19) was carried out in sat. NaHCO3-CH2Cl2 and 5% NaOH-CH2Cl2 to give several kinds of 4-thiazolones (3-5, 10, 12 and 15), thiazin-4-one (18) and spiro compounds (21).
