Synthesis and hypolipidemic and antidiabetogenic activities of .beta.,.beta.,.beta.',.beta.'-tetrasubstituted, long-chain dioic acids
摘要:
beta,beta,beta',beta'-Tetrasubstituted, long-chain dioic acids of the general formula HOOC-C(XY)-C(R2)-Q-C-(R2)-C(XY)-COOH have been synthesized and evaluated as hypotriglyceridemic-hypocholesterolemic agents in rats and as antidiabetogenic agents in ob/ob diabetic mice. The free carboxyl function of analogues of the series was mandatory for their hypolipidemic-antidiabetogenic effect while nonhydrolyzable diesters were inactive. Other structure-activity relationships were determined as a function of the overall chain length (C12-C22), alpha,alpha'-substitutions (X, Y = H, F, Cl, Br, OH, CN), beta, beta'-substitutions (R = CH3, C6H5), and core substitutions [Q = (CH2)10, (CH2)4CH = CH(CH2)4, 1,4-C6H10[(CH2)3]2, 1,4-C6H4[(CH2)3]2, 1,4-C6H4(CH = CHCH2)2, CH2(OCH2CH2)3OCH2)]. The most effective hypolipidemic-antidiabetogenic members of the series were alpha,alpha'-nonsubstituted, beta,beta'-methyl-substituted analogues of 14-18-carbon chains having either a saturated aliphatic core or a 1,4-bis(propenyl)benzene core in the cis/trans configuration. The hypotriglyceridemic rather than the hypocholesterolemic capacity of members of the series was found to correlate with their respective capacities as liver peroxisomal proliferators in rats.

A novel class of compounds has been found to be effective in blocking cholesterol and neutral lipid synthesis n-vivo without adversely affecting energy metabolism. The active compounds have the general formula
or in-vivo hydrolysable functional derivatives of the carboxylic groups thereof, wherein
R1 and R2 each independently represents an unsubstituted or substituted hydrocarbyl or heterocyclyl radical;
X and Y each independently represents hydrogen, optionally substituted lower alkyl, halogen, cyano, carboxy, lower alkoxycarbonyl or carbamoyl; and
Q represents a diradical consisting of a linear chain of 8 to 14 carbon atoms, one or more of which may be replaced by heteroatoms, said chain being optionally substituted by inert substituents and one or more of said carbon or heteroatom chain members optionally forming part of a ring structure.
The invention also provides pharmaceutical compositions comprising the aforementioned compounds of formula (I) for the treatment of obesity, hyperlipidemia and- maturity-onset diabetes.
