異維A酸EP雜質(zhì)D是異維A酸合成過程中產(chǎn)生產(chǎn)生的雜質(zhì),又名阿利維甲酸,是治療皮膚病領(lǐng)域的重要藥物,是全反式維甲酸(式II,化學名:3,7-二甲基-9-(2,6,6-三甲基環(huán)己烯-1-基)-2E,4E,6E,8E-全反式壬四烯酸)的9-順異構(gòu)體。
異維A酸EP雜質(zhì)D(式I化合物)的制備:在氮氣保護下,往反應(yīng)瓶中加入乙醇2L、全反式維甲酸100g,攪拌,然后升溫至50~55℃,加入PdCl289mg。反應(yīng)1.5h后,經(jīng)HPLC檢測產(chǎn)物純度為21%。反應(yīng)液緩慢降溫至0~5℃,保溫180分鐘,抽濾;濾液加入另一干凈反應(yīng)瓶中,繼續(xù)降溫至-10~-6℃,保溫20分鐘,抽濾,得到產(chǎn)物異維A酸EP雜質(zhì)D 12.1g,總收率12.1%,HPLC純度99.60%。以全反式維甲酸為原料,采用鈀化合物催化,在普通的工業(yè)級有機溶劑中可得到阿利維甲酸。方法操作簡便,成本低,條件可控,便于工業(yè)生產(chǎn);經(jīng)過后處理步驟后,可得到純度99%以上的阿利維甲酸,產(chǎn)物收率達到12%以上,具有較高的應(yīng)用價值。
9-cis-Retinoic acid (1-10 μM; 0-5 days; CA 9-22 and NA cells) treatment significantly decreases proliferation in a dose-dependent manner in CA 9-22 and NA cells.
9-cis-Retinoic acid (1 μM; 24 hours) treatment significantly increases PPARγ functional activity by >200% in CA 9-22 and NA aerodigestive cells.
9-cis-Retinoic acid treatment results in the formation of a nuclear PPARγ-RXRα heterodimer supershift complex in CA 9-22 cells.
9-cis-Retinoic acid inhibits proliferation and induces apoptosis in cutaneous T-cell lymphoma (CTCL) in a dose-dependent and time-dependent manner. 9-cis-Retinoic acid also induces G0/G1 cell cycle arrest by downregulation of cyclin D1. 9-cis-Retinoic acid significantly decreases phosphorylation of JAK1, STAT3, and STAT5 and downregulated Bcl-xL and cyclin D1.
