yl]methyl]-3-methoxybenzoyl]-2-methylbenzenesulfonamide, ICI 204,219; pKB = 9.67 +/- 0.13, Ki = 0.3 +/- 0.03 nM, po ED50 = 0.3 mg/kg] is currently under clinical investigation for asthma. In the indole series, certain alkylsulfonyl amides possessing a 3-cyanobenzyl substituent at the N-1 position (60, 61) were produced that had KB less than or equal to 10(-9) M on guinea pig trachea.
已经研究了1,3,5-取代的吲哚和吲唑作为肽白三烯的受体拮抗剂。这些化合物中最好的化合物通常在N1位具有甲基,在C-5位具有[(环戊氧基)羰基]氨基或2-环戊基乙酰氨基或N'-环戊基脲基,而芳基磺酰基酰胺基则是酸性的一部分。链在环的C-3位置。此类化合物在豚鼠气管上对LTE4的激动剂的离解常数(KB)在10(-9)-10(-11)M范围内,抑制常数(Ki)小于或等于10(-9)M豚鼠薄壁膜对[3H] LTD4的影响。许多化合物以小于或等于1 mg / kg的剂量对豚鼠阻断LTD4诱导的“呼吸困难”有效。化合物45 [N- [4-[[5-[[(环戊氧基氧基)羰基]-氨基] -1-甲基吲哚-3-基]甲基] -3-甲氧基苯甲酰基] -2-甲基苯磺酰胺,ICI 204,219;化合物45。目前正在对哮喘进行pKB = 9.67 +/- 0.13,Ki = 0.3 +/- 0.03 nM,po ED50
