Synthetic Route of 43039-98-1, An article , which mentions 43039-98-1, molecular formula is C6H7NOS. The compound – 1-(Thiazol-2-yl)propan-1-one played an important role in people’s production and life.
(Methoxyalkyl)thiazoles are novel 5-lipoxygenase (5-LPO) inhibitors that are neither redox agents nor iron chelators. Consideration of a hypothetical model of the enzyme active site led to this series which is exemplified by 1-[3(naphth-2-ylmethoxy)phenyl]-1-(thiazol-2-yl)propyl methyl ether (2d, ICI211965). 2d inhibits cell-free guinea pig 5-LPO activity, LTC4 synthesis in plasma free mouse macrophages, and LTB4 synthesis in rat and human blood (IC50s 0.1 muM, 8nM, 0.5 muM, and 0.4 muM, respectively) but does not inhibit the synthesis of cyclooxygenase products at concentrations up to 50 muM in macrophages and 100 muM in blood. 2d is orally active in rat (ex vivo ED50 10 mg/kg in blood taken in 1h after dosing). SAR studies show that high in vitro potency requires methoxy, thiazolyl, and naphthyl groups and depends critically on the substitution pattern. (Methoxyalkyl)thiazoles are chiral. Resolution of 1-methoxy-6-(naphth-2-ylmethoxy)-1-(thiazol-2-yl)indan (2j, ICl216800) shows that (+)-2j is 50-150-fold more potent than (-)-2j in in vitro assays. Thus, (methoxyalkyl)thiazoles are a new series of orally active, selective 5-LPO inhibitors and represent the first class of inhibitors in which inhibition is mediated by specific, enantioselective interactions with the enzyme.
