The seeds of the akuamma tree (Picralima nitida) have been used as a traditional treatment for pain and fever. Previous studies have attributed these effects to a series of indole alkaloids found within the seed extracts; however, these pharmacological studies were significantly limited in scope. Herein, an isolation protocol employing pH-zone-refining countercurrent chromatography was developed to provide six of the akuamma alkaloids in high purity and quantities sufficient for more extensive biological evaluation. Five of these alkaloids, akuammine (1), pseudo-akuammigine (3), akuammicine (4), akuammiline (5), and picraline (6), were evaluated against a panel of >40 central nervous system receptors to identify that their primary targets are the opioid receptors. Detailed in vitro investigations revealed 4 to be a potent kappa opioid receptor agonist, and three alkaloids (1-3) were shown to have micromolar activity at the mu opioid receptor. The mu opioid receptor agonists were further evaluated for analgesic properties but demonstrated limited efficacy in assays of thermal nociception. These findings contradict previous reports of the antinociceptive properties of the P. nitida alkaloids and the traditional use of akuamma seeds as analgesics. Nevertheless, their opioid-preferring activity does suggest the akuamma alkaloids provide distinct scaffolds from which novel opioids with unique pharmacologic properties and therapeutic utility can be developed.

Hydrogen-bonded polyamide 6/Zr-MOF mixed matrix membranes for efficient natural gas dehydration

New types of mixed matrix membranes (MMMs) were fabricated by incorporating Zr-MOF (UiO-66-NH2 and UiO66-NH3+Cl-) filler into polyamide 6 (PA 6) polymer, enabling efficient natural gas dehydration. All membranes were characterized and applied for H2O/CH4 mixtures separation at 1 bar pressure difference at 30 degrees C. It was found that the Zr-MOF nanoparticles in a size range of 0.4-0.5 mu m were successfully incorporated into the high permeability polymer PA 6 to obtain MMMs with 10-30 wt% particle loadings. MMMs loaded with 25 wt% of UiO-66-NH3+Cl- and 20 wt% of UiO-66-NH2 demonstrated ultrahigh H2O/CH4 selectivity of 747.7 and 687.4, respectively, and enhanced H2O permeability as well as H2O/CH4 selectivity compared with the pure PA 6 polymer. The excellent membrane performance attributed to direct and extensive hydrogen bonds between the polymer and MOFs. This type of MMMs could be an alternative for further research in H2O/CH4 separation at industrial scale.

Enantioselective C2-Alkylation of Indoles through a Redox-Relay Heck Reaction of 2-Indole Triflates

A palladium-catalyzed enantioselective redox-relay Heck reaction of 2-indole triflates and disubstituted alkenes is reported. This process combines readily available indole triflates with a variety of alkenes to afford a range of indole derivatives bearing a stereocenter adjacent to C2. Enantioselectivity is achieved through use of a simple pyridine-oxazoline ligand. Tuning the electronics of the indole, through judicious choice of N-protecting group, is required to ensure selective beta-hydride elimination away from the indole core. Utility of this method is highlighted in a modular formal synthesis of an S1P(1) agonist precursor developed by Merck.

Structural basis for non-radical catalysis by TsrM, a radical SAM methylase

Crystal structures of a cobalamin-dependent radical S-adenosylmethionine (SAM) methylase reveal an unexpected mechanism that involves substrate-assisted catalysis whereby the carboxylate group of the co-substrate SAM serves as a general base. Tryptophan 2C methyltransferase (TsrM) methylates C2 of the indole ring of l-tryptophan during biosynthesis of the quinaldic acid moiety of thiostrepton. TsrM is annotated as a cobalamin-dependent radical S-adenosylmethionine (SAM) methylase; however, TsrM does not reductively cleave SAM to the universal 5MODIFIER LETTER PRIME-deoxyadenosyl 5MODIFIER LETTER PRIME-radical intermediate, a hallmark of radical SAM (RS) enzymes. Herein, we report structures of TsrM from Kitasatospora setae, which are the first structures of a cobalamin-dependent radical SAM methylase. Unexpectedly, the structures show an essential arginine residue that resides in the proximal coordination sphere of the cobalamin cofactor, and a [4Fe-4S] cluster that is ligated by a glutamyl residue and three cysteines in a canonical CXXXCXXC RS motif. Structures in the presence of substrates suggest a substrate-assisted mechanism of catalysis, wherein the carboxylate group of SAM serves as a general base to deprotonate N1 of the tryptophan substrate, facilitating the formation of a C2 carbanion.
