The bioavailability of a drug which is not readily absorbed in the digestive tract can be greatly enhanced by administering an oral composition comprising a drug and a compound of formula (I):
wherein,
X is CN, COOH, COOR10(wherein R10 is C1-2 alkyl), SO2Ph or SPh;
k, l, m and n are each independently an integer of 0 to 4;
R1 is H or C1-3 alkyl; and
R2, R3, R4, R5, R6, R7, R8 and R9 are each independently H, OH or C1-3 alkoxy.
通过服用由药物和式 (I) 化合物组成的口服组合物,可大大提高在消化道不易吸收的药物的生物利用度:
其中
X 是 CN、COOH、COOR10(其中 R10 是 C1-2 烷基)、SO2Ph 或 SPh;
k、l、m 和 n 各自独立地为 0 至 4 的整数;
R1 是 H 或 C1-3 烷基;以及
R2、R3、R4、R5、R6、R7、R8 和 R9 各自独立地为 H、OH 或 C1-3 烷氧基。
