Novel and potent ACAT (acyl-CoA: cholesterol O-acyltransferase) inhibitors, (R)-N-2-(1,3-benzodioxol-4-yl)heptyl-N'-2,6-diisopropylphenylur ea (2a, EAB-309), and its enantiomer 2b (EAB-310), were prepared from 4-(1,3-benzodioxole)carbaldehyde (7) via optically active (R or S)-2-(1,3- benzodioxol-4-yl)heptanoic acid (12a or 12b). Compound 2a showed potent inhibitory effects on ACATs in vitro, and lowered
新型有效的ACAT(酰基CoA:胆固醇O-酰基转移酶)抑制剂,(R)-N-2-(1,3-苯并二恶唑-4-基)庚基-N'-2,6-二异丙基苯基脲(2a,EAB -309)及其对映异构体2b(EAB-310)由4-(1,3-苯并二恶唑)甲醛(7)通过光学活性(R或S)-2-(1,3-苯并二恶唑-4- yl)庚酸(12a或12b)。化合物2a在体外显示出对ACAT的有效抑制作用,并在体内降低了血浆胆固醇。抑制大鼠肝微粒体ACAT的IC50值为5 nM。在仓鼠和大鼠模型中,降血脂活性的ED30值分别为0.25和0.75 mg / kg po。结果表明2a有潜力成为一种新型的降胆固醇和抗动脉粥样硬化剂。2a在体外和体内的活性仅是对映体2b的几倍。
