Heck Diversification of Indole-Based Substrates under Aqueous Conditions: From Indoles to Unprotected Halo-tryptophans and Halo-tryptophans in Natural Product Derivatives

The blending of synthetic chemistry with biosynthetic processes provides a powerful approach to synthesis. Biosynthetic halogenation and synthetic cross-coupling have great potential to be used together, for small molecule generation, access to natural product analogues and as a tool for chemical biology. However, to enable enhanced generality of this approach, further synthetic tools are needed. Though considerable research has been invested in the diversification of phenylalanine and tyrosine, functionalisation of tryptophans thorough cross-coupling has been largely neglected. Tryptophan is a key residue in many biologically active natural products and peptides; in proteins it is key to fluorescence and dominates protein folding. To this end, we have explored the Heck cross-coupling of halo-indoles and halo-tryptophans in water, showing broad reaction scope. We have demonstrated the ability to use this methodology in the functionalisation of a brominated antibiotic (bromo-pacidamycin), as well as a marine sponge metabolite, barettin.

Molecular recognition in the P2Y14 receptor: Probing the structurally permissive terminal sugar moiety of uridine-5?-diphosphoglucose

The P2Y14 receptor, a nucleotide signaling protein, is activated by uridine-5?-diphosphoglucose 1 and other uracil nucleotides. We have determined that the glucose moiety of 1 is the most structurally permissive region for designing analogues of this P2Y14 agonist. For example, the carboxylate group of uridine-5?-diphosphoglucuronic acid proved to be suitable for flexible substitution by chain extension through an amide linkage. Functionalized congeners containing terminal 2-acylaminoethylamides prepared by this strategy retained P2Y14 activity, and molecular modeling predicted close proximity of this chain to the second extracellular loop of the receptor. In addition, replacement of glucose with other sugars did not diminish P2Y14 potency. For example, the [5??]ribose derivative had an EC50 of 0.24 muM. Selective monofluorination of the glucose moiety indicated a role for the 2??- and 6??-hydroxyl groups of 1 in receptor recognition. The beta-glucoside was twofold less potent than the native alpha-isomer, but methylene replacement of the 1??-oxygen abolished activity. Replacement of the ribose ring system with cyclopentyl or rigid bicyclo[3.1.0]hexane groups abolished activity. Uridine-5?-diphosphoglucose also activates the P2Y2 receptor, but the 2-thio analogue and several of the potent modified-glucose analogues were P2Y14-selective.

Enantioselective organo-SOMO cascade cycloadditions: A rapid approach to molecular complexity from simple aldehydes and olefins

A highly selective, radical-mediated (4 + 2) coupling reaction of aldehydes and conjugated olefins has been achieved through asymmetric SOMO-catalysis. A radical-polar crossover mechanism is proposed wherein olefin addition to a transient enamine radical cation and oxidation of the resulting radical furnishes a cation which is vulnerable to nucleophilic addition. A range of aromatic aldehydes are shown to couple with styrenes and dienes to provide cyclic products with high chemical efficiency, regioselectivity, and stereoselectivity.

A Novel (R)-Imine Reductase from Paenibacillus lactis for Asymmetric Reduction of 3 H-Indoles

A novel (R)-imine reductase (PlRIR) from Paenibacillus lactis was heterologously overexpressed in Escherichia coli, purified and characterized. The purified PlRIR exhibited relatively high catalytic efficiency (kcat/Km=1.58 s-1 mm-1) towards 2,3,3-trimethylindolenine. A panel of 3H-indoles and 3H-indole iodides were reduced by PlRIR to yield the corresponding products with good-to-excellent enantioselectivity (66-98 % ee). In addition, PlRIR also possesses good activities toward other types of imines such as pyrroline, tetrahydropyridine, and dihydroisoquinoline, indicating a reasonably broad substrate acceptance. In a 100 mg scale preparative reaction, 100 mm 2,3,3-trimethylindolenine was converted efficiently to afford (R)-2,3,3-trimethylindoline with 96 % ee and 81 % yield.

Synthesis and preliminary cytotoxicity study of glucuronide derivatives of CC-1065 analogues

Glucuronide derivatives of CBI-bearing CC-1065 analogues have been synthesized, and their cytotoxicities tested against U937 leukemia cells. The new compounds show potent antitumor activity in vitro. Compounds 1 and 2, and their corresponding glucuronides 3 and 4 have IC50 values of 0.6, 0.1, 1.4 and 0.6 nM, respectively. Glucuronide 3 is approximately 2-fold less toxic than its hydroxyl counterpart 1, and glucuronide 4 is approximately 6-fold less toxic than its hydroxyl counterpart 2. Glucuronides 3 and 4 may have limited use in the ADEPT approach. However, they may be used as antitumor agents in a conventional way.

Synthesis and Dopamine Agonist Properties of (+/-)-trans-3,4,4a,10b-Tetrahydro-4-propyl-2H,5H-<1>benzopyrano<4,3-b>-1,4-oxazin-9-ol and Its Enantiomers

The dopamine agonist profile of (+/-)-trans-3,4,4a,10b-tetrahydro-4-propyl-2H,5H-<1>benzopyrano<4,3-b>-1,4-oxazin-9-ol (16a) and its enantiomers (16b-c) was examined.Racemic 16a exhibited moderate affinity for the dopamine (DA) D2 receptor labeled with the DA antagonist ligand <3H>haloperidol and moderate in vivo activity; it attenuated gamma-butyrolactone-stimulated DA synthesis, decreased DA neuronal firing of substantia nigra DA neurons, and inhibited exploratory locomotor activity in rats, a profile consistent with a DA autoreceptor agonist mechanism of action.The (+)-enantiomer 16b possessed greater DA receptor affinity with the agonist ligand <3H>-N-propylnorapomorphine then with the antagonist ligand.In rats it potently inhibited DA synthesis and neuronal firing and also inhibited exploratory locomotion.The (-)-enantiomer, on the other hand, did not have significant activity in any of these tests.This profile indicates that like many other rigid DA agonists, the dopaminergic activity resides in one enantiomer, in this case the (+)-enantiomer 16b.On the basis of single-crystal X-ray analysis of a key intermediate, the absolute configuration of 16b was found to be 4aR, 10bR.
