Chofunikira chapakati pakubalalitsa utoto.Ndiwonso wapakatikati wa mankhwala ozindikira matenda a ubiquitin (wothandizira kusiyanitsa ndi X-ray);Amagwiritsidwanso ntchito popanga mankhwala osokoneza bongo a PDE IV inhibitor glycolinic acid;Amagwiritsidwanso ntchito ngati wapakatikati pakubalalitsa utoto (mitundu ya buluu azo).
sulfuric acid (104.3mL, 1.92mol) idawonjezeredwa m'mabotolo atatu, kenako isophthalic acid (40g, 0.24mol) idawonjezedwa, kusonkhezeredwa ndikutenthedwa mpaka 60 ℃, yomwe inachitikira 0.5h, ndi 60% nitric acid (37.8g, 0.36) mol) adawonjezedwa kuti azitha kuwongolera kuchuluka kwa madontho.Onjezani mu maola awiri.Pambuyo pake, kutentha kusungirako ku 60 ℃ kwa maola awiri.Kuzizira mpaka pansi pa 50 ° C, kenaka yikani 100mL yamadzi.Zinthuzo zinali utakhazikika kutentha kwa firiji, anatsanulira mu fyuluta, amapopedwa kuchotsa zinyalala asidi, keke fyuluta anatsukidwa ndi madzi, chatsanulidwa kuti recrystallize, ndi mankhwala woyera anali 34,6 magalamu, zokolola anali 68,4%.
