Compounds of the structure where A is straight or branched divalent alkylene or divalent cycloalkylene, R1 is selected from hydrogen; alkylthio; optionally substituted phenylthio; optionally substituted phenylalkylthio; optionally substituted 2-, 3-, and 4-pyridyl; optionally substituted 2-, and 3-thienylthio; and optionally substituted 2-thiazolythio, R2 is selected from -COOB; -COOalkyl; -COOalkyl(carbocyclic aryl); -CONR5R6 ; -COR6 ; and -OH, R3 is selected from phenylalkyl and heteroarylalkyl, and R4 is selected from optionally substituted alkoxy(carbocyclic aryl); optionally substituted carbocyclic aryloxy; optionally substituted heteroarylalkoxy; and optionally substituted heteroaryloxy are potent inhibitors of lipoxygenase enzymes and thus inhibit the biosynthesis of of leukotrienes. These compounds are useful in the treatment or amelioration of allergic and inflammatory disease states
(Quinolin-2-ylmethoxy)indoles as inhibitors of the biosynthesis of leukotrienes

, (2008/06/13)
Compounds having the formula I: STR1 are inhibitors of leukotriene biosynthesis. These compounds are useful as anti-asthmatic, anti-allergic, anti-inflammatory, and cytoprotective agents. They are also useful in treating diarrhea, hypertension, angina, platelet aggregation, cerebral spasm, premature labor, spontaneous abortion, dysmenorrhea, and migraine.

A form of 3-[N-(p-chlorobenzyl)-3-(t-butylthio)-5-(quinolin-2-ylmethoxy)indol-2-yl]-2,2-dimethylpropanoic acid sodium salt, obtained by freeze or spray drying, is more soluble in water than the crystalline form thereof. The compound is useful as an anti-a
Thiopyrano[2,3,4-c,d]indoles as inhibitors of leukotriene biosynthesis

Compounds having the formula I: STR1 are 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, psoriasis, uveitis and allograft rejection and in preventing the formation of atherosclerotic plaques.

Thiopyrano[2,3,4-c,d]indoles are a new class of 5-lipoxygenase (5-LO) inhibitors. SAR studies have demonstrated that the thiopyran ring, the 5- phenylpyridine substituent, and an acidic functional group on a four-carbon C-2 side chain are all required for optimal inhibitor potency. In contrast, the indolic nitrogen may be substituted with a variety of lipophilic groups. As a result of the SAR investigation, 44 (L-691,816; 5-[3-[1-(4- chlorobenzyl)-4-methyl-6-[(5-phenylpyridin-2-yl)methoxy]-4,5-dihydro-1H- thiopyrano[2,3,4-c,d]indol-2-yl]-2,2-dimethylpropyl]-1H-tetrazole) has been identified as a potent inhibitor of the 5-LO reaction both in vitro and in a range of in vivo models. Compound 44 inhibits 5-HPETE production by both rat and human 5-LO and LTB4 synthesis in human PMN leukocytes (IC50s 16, 75, and 10 nM, respectively). The mechanism of inhibition of 5-LO activity by compound 44 appears to involve the formation of a reversible deadend complex with the enzyme and does not involve reduction of the nonheme iron of 5-LO. Compound 44 is highly selective for 5-LO when compared to the inhibition of human FLAP, porcine 12-LO, and also ram seminal vesicle cyclooxygenase. In addition, 44 is orally active in a rat pleurisy model (inhibition of LTB4, ED50 = 1.9 mg/kg; 8 h pretreatment) as well as in the hyperreactive rat model of antigen-induced dyspnea (ED50 = 0.1 mg/kg; 2-h pretreatment). Excellent functional activity was also observed in both the conscious allergic monkey and sheep models of asthma. In the latter case, the functional activity observed correlated with the inhibition of urinary LTE4 excretion.
