The mitochondrial D-loop region of the pig, Sus scrofa, was found to be several hundred base pairs larger than the corresponding region in cow, a related artiodactyl species, primarily because of an insertion containing the tandemly repeated sequence CGTGCGTACA. Porcine mitochondrial DNA from the tissue of a single animal exhibits a large population of… (More)
Statins, because of their excellent efficacy and manageable safety profile, represent a key component in the current armamentarium for the treatment of hypercholesterolemia. Nonetheless, myopathy remains a safety concern for this important drug class. Cerivastatin was withdrawn from the market for myotoxicity safety concerns. BMS-423526… (More)
The goal of the present study was to determine the molecular mechanism whereby transforming growth factor b (TGFb) increases smooth muscle (SM) a-actin expression. Confluent, growth-arrested rat aortic smooth muscle cells (SMC) were transiently transfected with various SM a-actin promoter/chloramphenicol acetyltransferase deletion mutants and stimulated… (More)
3-hydroxy-3-methylglutaryl coenzyme-A reductase (HMGR) inhibitors, more commonly known as statins, represent the gold standard in treating hypercholesterolemia. Although statins are regarded as generally safe, they are known to cause myopathy and, in rare cases, rhabdomyolysis. Statin-dependent effects on plasma lipids are mediated through the inhibition of… (More)
A series of 2,4,5-tri-substituted imidazoles has proven to be highly potent in inhibiting mammalian 15-lipoxygenase (15-LO) with excellent selectivity over human isozymes 5- and P-12-LO. Non-symmetrical sulfamides (e.g., 21a-n) were found to be suitable replacements for the earlier arylsulfonamide-containing members of this series (e.g., 2, 14a-p). Several… (More)
A series of inhibitors of mammalian 15-lipoxygenase based on tryptamine and homotryptamine scaffolds is described. Compounds with aryl substituents at C-2 of the indole core of tryptamine and homotryptamine sulfonamides (e.g., 37a-p) proved to be potent inhibitors of the isolated enzyme. Selected compounds also demonstrated desirable inhibition… (More)
A series of benzodiazepine-based inhibitors of mitochondrial F(1)F(0) ATP hydrolase were prepared and evaluated for their ability to selectively inhibit the enzyme in the forward direction. Compounds from this series showed excellent potency and selectivity for ATP hydrolase versus ATP synthase, suggesting a potentially beneficial profile useful for the… (More)
A series of inhibitors of mammalian 15-lipoxygenase (15-LO) based on a 3,4,5-tri-substituted pyrazole scaffold is described. Replacement of a sulfonamide functionality in the lead series with a sulfamide group resulted in improved physicochemical properties generating analogs with enhanced inhibition in cell-based and whole blood assays.
The preferred absolute configuration of two series of F(1)F(0)-ATP synthase inhibitors was determined. Although the configuration of the active enantiomer in each series is different, each series presents the same 'triaryl' pharmacophore to the enzyme binding site.
A series of substituted guanidine derivatives were prepared and evaluated as potent and selective inhibitors of mitochondrial F(1)F(0) ATP hydrolase. The initial thiourethane derived lead molecules possessed intriguing in vitro pharmacological profiles, though contained moieties considered non-drug-like. Analogue synthesis efforts led to compounds with… (More)
