如题 Ketorolac的结构分类? 维基百科写说 Although its name does not suggest similarity with propionic acid derivatives (e.g. ketoprofen, flurbiprofen, naproxen, ibuprofen, carprofen etc.), ketorolac is an isostere of ketoprofen. More precisely, it is a dihydropyrrolizine carboxylic acid derivative structurally related to indomethacin. 所以Ketolor是和ketoprofen, flurbiprofen, naproxen, ibuprofen 同类属propionic acid类衍生物, 还是和Diclofenac,Etodolac,Indomethacin,Sulindac属Acetic acids类衍生物 (因为有ac结尾) ? 谢谢
