beta,beta,beta’,beta’-Tetrasubstituted, long-chain dioic acids of the general formula HOOC-C(XY)-C(R2)-Q-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 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 proliferation in rats.

Recommanded Product: 17347-61-4, In chemical reaction engineering, simulations are useful for investigating and optimizing a particular reaction process or system.

A nickel-catalyzed alkylation of succinic and glutaric anhydrides with alkyl- and arylzinc reagents has been developed. A dramatic olefin effect has been investigated resulting in the identification of several styrene-based promoters which show pronounced enhancements in reaction rate. The substrate scope with respect to electrophilic and nucleophilic coupling partners has been examined and found to be remarkably broad, allowing for rapid introduction of molecular complexity through the use of functionalized coupling partners. Regioselective alkylation of an unsymmetrical succinic anhydride and a profound effect of pendent coordinating olefins on reaction rate suggest a mechanism involving discrete oxidative addition of the nickel complex into the cyclic anhydride followed by a transmetalation event.

The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 17347-61-4, 2,2-Dimethylsuccinicanhydride, introducing its new discovery.

Betulinic acid (BA), a pentacyclic triterpenoid, exhibits broad spectrum antiproliferative activity, but generally with only modest potency. To improve BA’s pharmacological properties, fluorine was introduced as a single atom at C-2, creating two diastereomers, or in a trifluoromethyl group at C-3. We evaluated the impact of these groups on antiproliferative activity against five human tumor cell lines. A racemic 2-F-BA (compound 6) showed significantly improved antiproliferative activity, while each diastereomer exhibited similar effects. We also demonstrated that 2-F-BA is a topoisomerase (Topo) I and IIalpha dual inhibitor in cell-based and cell-free assays. A hypothetical mode of binding to the Topo I-DNA suggested a difference between the hydrogen bonding of BA and 2-F-BA to DNA, which may account for the difference in bioactivity against Topo I.
