PCT No. PCT/GB92/01968 Sec. 371 Date Jun. 30, 1993 Sec. 102(e) Date Jun. 30, 1993 PCT Filed Oct. 27, 1992Biphenylylquinuclidine compounds of the formula I: I and pharmaceutically-acceptable salts thereof; wherein R1 is hydrogen or hydroxy; R2 is hydrogen; or R1 and R2 are joined together so that CR1-CR2 is a double bond; and one or both ring A and ring B may be optionally unsubstituted or independently substituted by one or more substituents selected from halogeno, hydroxy, amino, nitro, cyano, carboxy, carbamoyl, (1-6C)alkyl, (1-6C)alkoxy, (1-6C)alkylamino, di-[(1-6C)alkyl]amino, N-[(1-6C)alkyl]carbamoyl, N,N-di-[(1-6C)alkyl]carbamoyl, (1-6C)alkoxycarbonyl, (1-6C)alkylthio, (1-6C)alkylsulphinyl, (1-6C)alkylsulphonyl and halogeno-(1-6C)alkyl; are inhibitors of squalene synthase and are hence useful in treating diseases or medical conditions such as hypercholesterolemia, atherosclerosis and fungal diseases. Methods of using these compounds to treat such conditions, novel compounds, processes for making these compounds and pharmaceutical compositions containing them are claimed.
