Compounds of formula (I): ##STR1## wherein: R.sup.1 is alkyl; R.sup.2a, R.sup.2b, R.sup.2c and R.sup.2d are the same or different and each is hydrogen, optionally substituted alkyl, --(C.dbd.O)--B.sup.1 (wherein B.sup.1 is hydrogen or alkyl), nitro, --NR.sup.c R.sup.d (wherein R.sup.c is hydrogen or alkyl and Rd is alkyl), hydroxy, protected hydroxy group, alkoxy, cyano, alkylthio, alkylsulfinyl, alkylsulfonyl or halogen; R.sup.3 is alkyl; R.sup.4 is a group of the formula (II) ##STR2## wherein A.sup.1 is a single bond, alkylene or alkenylene; R.sup.5a and R.sup.5b are the same or different and each is hydrogen, alkyl or --A.sup.4 R.sup.5.sub.c wherein A is a single bond, alkylene or alkenylene and R.sup.5.sub.c is alkoxy; and n is 0, and pharmaceutically acceptable salts thereof. Such compounds have valuable inhibitory activity against acyl-CoA (cholesterol acyl transferase).
公式(I)的化合物:##STR1## 其中:R.sup.1是烷基;R.sup.2a、R.sup.2b、R.sup.2c和R.sup.2d相同或不同,每一个都是氢,可选地取代烷基,--(C.dbd.O)--B.sup.1(其中B.sup.1是氢或烷基),硝基,--NR.sup.c R.sup.d(其中R.sup.c是氢或烷基且Rd是烷基),羟基,保护的羟基团,烷氧基,氰基,烷基亚砜,烷基亚磺酰基或卤素;R.sup.3是烷基;R.sup.4是公式(II)的组##STR2## 其中A.sup.1是单键,亚烷基或亚烯基;R.sup.5a和R.sup.5b相同或不同,每一个都是氢,烷基或--A.sup.4 R.sup.5.sub.c,其中A是单键,亚烷基或亚烯基且R.sup.5.sub.c是烷氧基;n是0,以及药用可接受的盐。这样的化合物对于酰基-CoA(胆固醇酰基转移酶)具有宝贵的抑制活性。
