Ethnopharmacology of Souroubea sympetala and Souroubea gilgii (Marcgraviaceae) and identification of betulinic acid as an anxiolytic principle

The neotropical lianas Souroubea gilgii and Souroubea sympetala (Marcgraviaceae) were chosen for study as part of a phytochemical discovery strategy focusing on rare plant families in Central America. In participatory research, Q’eqchi’ healers in Belize reported the use of these plants to reverse psychological symptoms inflicted by witchcraft. Extracts of two Souroubea species showed significant anti-anxiety activity in the elevated plus maze, a standardized test paradigm. Bioassay guided isolation led to the active principle, the pentacyclic triterpene, betulinic acid, which had activity in the elevated plus maze at 0.5 mg/kg. Other phytochemicals isolated included alpha- and beta-amyrin, 2-hydroxyursolic acid, taraxenyl trans-4-hydroxy-cinnamate, naringenin, methyl ursolate, eriodytiol, methyl 2-alpha-hydroxyursolate, methyl 2-alpha-hydroxymaslinate, methyl betulinate, and condrilla sterol.

Purification and characterization of alpha-keto amide reductase from Saccharomyces cerevisiae

An NADPH-dependent alpha-keto amide reductase was purified from Saccharomyces cerevisiae. The molecular mass of the native enzyme was estimated to be 33 and 36 kDa by gel filtration chromatography and SDS-polyacrylamide gel electrophoresis, respectively. The purified enzyme showed a reducing activity not only for aromatic alpha-keto amides but also for aliphatic and aromatic alpha-keto esters. The internal sequence of the enzyme was identical with that of a hypothetical protein (ORF YDL 124w) coded by yeast chromosome IV.

Optimization of brain penetrant 11beta-hydroxysteroid dehydrogenase type i inhibitors and in vivo testing in diet-induced obese mice

11beta-Hydroxysteroid dehydrogenase type 1 (11beta-HSD1) has been widely considered by the pharmaceutical industry as a target to treat metabolic syndrome in type II diabetics. We hypothesized that central nervous system (CNS) penetration might be required to see efficacy. Starting from a previously reported pyrimidine compound, we removed hydrogen-bond donors to yield 3, which had modest CNS penetration. More significant progress was achieved by changing the core to give 40, which combines good potency and CNS penetration. Compound 40 was dosed to diet-induced obese (DIO) mice and gave excellent target engagement in the liver and high free exposures of drug, both peripherally and in the CNS. However, no body weight reduction or effects on glucose or insulin were observed in this model. Similar data were obtained with a structurally diverse thiazole compound 51. This work casts doubt on the hypothesis that localized tissue modulation of 11beta-HSD1 activity alleviates metabolic syndrome.

Proton grease: An acid accelerated molecular rotor

A molecular rotor was designed that rotates 7 orders of magnitude faster upon protonation. The quinoline rotor is based on a rigid N-arylimide framework that displays restricted rotation due to steric interaction between the quinoline nitrogen and imide carbonyls. At rt (23 C), the rotor rotates slowly (t1/2 = 26 min, DeltaG? = 22.2 kcal/mol). However, upon addition of 3.5 equiv of acid the rotor rotates rapidly (t 1/2 = 2.0 ¡Á 10-4 s, DeltaG? = 12.9 kcal/mol). Mechanistic studies show that this dramatic acid catalyzed change is due to stabilization of the planar transition state by the formation of an intramolecular hydrogen bond between the protonated quinoline nitrogen (N+-H) and an imide carbonyl (O=C). The acid catalyzed acceleration is reversible and can be stopped by addition of base.

Ashless additives for lubricating compositions

Superior ashless additives for lubricants are prepared by a process comprising first introducing a petroleum sulfonic acid and a polyamine to a reaction zone and subsequently introducing a cyclic anhydride of a dicarboxylic acid into the reaction zone. In another embodiment, the solids content of the additives is reduced to acceptable levels by removal of free SO2 from the petroleum sulfonic acid prior to preparing the additive. Lubricating oil compositions containing these ashless additives are also provided.

Synthesis of the core structure of apicularen a by transannular cyclization.

[reaction: see text] An approach to the macrocyclic core of apicularen A is described. Thus, cross-coupling of the aryl triflate 7 with the vinylstannane 19 provided the styrene 20. Deprotection led to the dihydroxy acid 22. Through a size-selective macrolactonization, the 12-membered macrolactone 23 was obtained. Treatment of 24 with N-phenyl selenophthalimide gave the desired trans-pyran 24. This approach might parallel the biosynthetic pathway.
