- NOVEL CYCLOHEXANE DERIVATIVE, PRODRUG THEREOF AND SALT THEREOF, AND THERAPEUTIC AGENT CONTAINING THE SAME FOR DIABETES
-
A cyclohexane derivative having the function of reducing a blood sugar level and having preferable properties required of medicines, such as long-lasting drug activity, metabolic stability, and safety; and a medicinal composition for use in the prevention or treatment of diseases attributable to hyperglycemia, such as diabetes, e.g., insulin dependent diabetes mellitus (type 1 diabetes) or noninsulin-dependent diabetes mellitus (type 2 diabetes), complications of diabetes, and obesity. The derivative is a compound represented by the formula (I): (wherein A is -O-, -CH2-, or -NH-; n is an integer selected between 0 and 1; R6 and R7 each independently is hydrogen or C1-6 alkyl; m is an integer selected among 1-3; Q is selected among the following formulae Q1 to Q5; Ar1 is optionally substituted arylene or optionally substituted heteroarylene, provided that the heteroarylene may be bonded to an aromatic carbocycle or aromatic heterocycle to form a fused ring; and Ar2 is optionally substituted aryl or optionally substituted heteroaryl), a prodrug of the compound, or a pharmaceutically acceptable salt of either. Also provided are a medicine, a medicinal composition, or the like each containing the compound.

- Synthesis and Liquid Crystal Behaviour of Further 4,4"-Disubstituted 2'-Fluoro-1,1':4',1"-Terphenyls
-
Further to earlier work on the liquid crystal properties of fluoro-1,1':4',1"-terphenyls we have now extended this series to include terminally fluoro- and cyano-substituted 2'-fluoro-1,1':4',1"-terphenyls, chiral 2'-fluoro-1,1':4',1"-terphenyls, and esters derived from 2'-fluoro-1,1':4',1"-terphenyls and incorporating the alkylcyclobutyl group.The preparations and transition temperatures for these series of compounds are presented and their transition temperatures and mesophase types are discussed.An interesting result from this work was the appearence of an S*C phase for one chiral homologue and of SC phases for the esters incorporating the alkylcyclobutyl group.The SC formation is attributed to the presence of the fluoro-substituent.Keywords: terphenyls, fluoroterphenyls, smectic C phases, cyclobutyl esters.

- TETRAZOLE DERIVATIVES, AND ANTI-ULCER COMPOSITION CONTAINING THE SAME
-
Tetrazole derivatives of the formula: STR1 wherein R 1 is a lower alkykl, phenyl or a group of the formula:--S(O) l--A--(X) m--R 3, and R 2 is hydrogen, a lower alkyl, phenyl or a cycloalkyl when R 1 is the group--S(O) l--A--(X) m--R 3, or R 2 is a group of the formula:--B--CO--R 4 when R 1 is a lower alkyl or phenyl and a pharmaceutically acceptable salt thereof, which have prophylactic or therapeutic activities against peptic and/or duodenal ulcers and are useful as an anti-ulcer drug; processes for the preparation of the tetrazole derivatives; and pharmaceutical composition containing said tetrazole derivatives.
