Biphenyl derivative of the formula: ##STR1## wherein R.sup.1 is hydrogen atom or a lower alkoxycarbonyl group and R.sup.2 is a lower alkoxycarbonyl group, or R.sup.1 and R.sup.2 are combined together to form a group of the formula: each of R.sup.3 and R.sup.4 is a lower alkoxy group; and Ring A is a substituted or unsubstituted sulfur-containing or nitrogen-containing heterocyclic ring, with the claims being drawn to Ring A as thiophene and a pharmaceutically acceptable salt thereof are disclosed. Said biphenyl derivative (I) and its salt have excellent hypolipidemic activity and are useful for treatment or prophylaxis of hyperlipidemia and/or arterioscelerosis.

Biphenyl derivative of the formula:
wherein R¹ is hydrogen atom or a lower alkoxycarbonyl group and R² is a lower alkoxycarbonyl group, or R¹ and R² are combined together to form a group of the formula:
each of R³ and R⁴ is a lower alkoxy group; and Ring A is a substituted or unsubstituted sulfur-containing or nitrogen-containing heterocyclic ring, and a pharmaceutically acceptable salt thereof are disclosed. Said biphenyl derivative (I) and its salt have excellent hypolipidemic activity and are useful for treatment or prophylaxis of hyperlipidemia and/or arteriosclerosis.
A series of diesters of arylnaphthalenelignan and their heteroaromatic analogs were synthesized and evaluated for hypolipidemic activity. The disasters with modifications at C-3 showed excellent hypocholesterolemic and high-density lipoprotein (HDL) cholesterol-elevating activities. Structure-activity analysis indicated that the 2-pyridylmethyl ester 5l has the optimum activity.
