Characterization of the amino acid adducts of the enedial derivative of teucrin A

The toxicity of germander, a herb used to treat obesity, is attributed to cytochrome P450 activation of the furan ring of its major diterpenoid component (teucrin A) into a reactive metabolite capable of adducting proteins. 1,4-Enedials have been proposed to be the reactive products of metabolism, possibly arising from a rearrangement of putative epoxide intermediates. We synthesized the enedial derivative of teucrin A as well as the enedial derived from a model furan, 3-(4-methoxy-benzyloxymethyl)-furan, by dimethyldioxirane oxidation and characterized the products of their reactions with amino acids and peptides. The reactions of the model enedial, 2-(4-methoxy-benzyloxymethyl)-but-2-enedial,withN-acetyl lysine (NAL) afforded regioisomeric N-alkyl-3-pyrrolin-2-ones, differing in the substitution on the double bond of the heterocyclic ring. Novel products formed in the reactions of the model enedial with N-acetyl cysteine (NAC) and both NAC/NAL uncovered the existence of tautomerization between the enedial and a hydroxyenal, which was manifest by the loss of 4-methoxybenzylalcohol and the incorporation of a second molecule of NAC. The reactions of teucrin A-enedial with NAC and NAL afforded analogues of the products observed with the model enedial, and the existence of the tautomeric equilibrium resulted in epimerization of the proton (H12) adjacent to the former furan ring. This work further illuminates the complex chemical behavior of unsaturated dialdehydes as an important class of toxic metabolites and lays the foundation for studies of the protein targets of teucrin A-enedial.

Switchable Synthesis of Pyrroles and Pyrazines via Rh(II)-Catalyzed Reaction of 1,2,3-Triazoles with Isoxazoles: Experimental and DFT Evidence for the 1,4-Diazahexatriene Intermediate

4-Aminopyrrole-3-carboxylates and pyrazine-2-carboxylates were synthesized from 5-alkoxyisoxazoles and 1-sulfonyl-1,2,3-triazoles by tuning the Rh(II) catalyst and the reaction conditions. The reaction in chloroform at 100 degrees C under Rh-2(OAc)(4) catalysis provides 4-aminopyrrole-3-carboxylates in good yields. The use of Rh-2(Piv)(4) in refluxing toluene results in the formation of 1,2-dihydropyrazine-2-carboxylates as the main products, which can be converted by a one-pot procedure to pyrazine-2-carboxylates by heating with catalytic amounts of TsOH. According to the NMR and DFT investigations of the reaction mechanism, pyrroles and dihydropyrazines are formed, respectively, via 1,5- and 1,6-cyclization of common (5Z)-1,4-diazahexa-1,3,5-triene intermediates. The influence of the nature of the catalyst on the product distribution is rationalized in terms of the Rh-catalyzed isomerization of a pyrrolin-2-ylium-3-aminide zwitterion, the primary product of 1,4-diazahexatriene 1,5-cyclization.

Highly Selective Sub-Nanomolar Cathepsin S Inhibitors by Merging Fragment Binders with Nitrile Inhibitors

Pharmacological inhibition of cathepsin S (CatS) allows for a specific modulation of the adaptive immune system and many major diseases. Here, we used NMR fragment screening and crystal structure-aided merging to synthesize novel, highly selective CatS inhibitors with picomolar enzymatic Ki values and nanomolar functional activity in human Raji cells. Noncovalent fragment hits revealed binding hotspots, while the covalent inhibitor structure-activity relationship enabled efficient potency optimization.

Reactions with pyrrolidine-2,4-diones, part 4*: Synthesis of some 3-substituted 1,5-diphenylpyrrolidine-2,4-diones as potential antimicrobial, anti-HIV-1 and antineoplastic agents

The condensation of 1,5-dipheiiylpyrrolidine-2,4-dione (1) with ethyl orthoformate yielded 3-ethoxymethylene-1,5-diphenylpyrrolidinc-2,4-dione (2). Reaction of the latter with hydrazine hydrate, secondary amines 7a-c or urea afforded the corresponding 3-substituted aminomethylene-1,5-diphenylpyrrolidene-2,4-diones 3, 8a-c or 9. On the other hand, condensation of 3 With veratraldehyde (5a) yielded 3-[(3,4-dimethoxybenzylidene)hydrazinomethylene]-1,5-diphenylpyrrolidine-24-dione (6). Whereas, cyclization of 9 with the reactive malonate ester 11 produced 3-[(5-butyl-4-hydroxy-2,6dioxo- 1,2,3,6- tetralhydropyrimidin-1-yl) methylene]-1,5-diphenylpyrrolidine-2,4-dione (12). The condensation of some selected aromatic aldehydes 5a-c and addition of morpholine (7c) or piperidine (7d) to some of the resulting 3-arylidene,1,5-diphenylpyrrolidine-2,4-diones 13b, e gave the respective 3-substituted methyl-4-hydroxy-1,5-diphenyl-Delta (3)-pyrrolin-2-ones 14a-c. Selected members of the new series were screened for their in vitro antimicrobial, anti-HIV-1 and antineoplastic activities. Two compounds 14a, b showed pronounced inhibitory activities against Gram-positive bacteria; whereas, in the in vitro anti-HIV-1 screening, only one compound Be displayed a moderate activity. However, in the antineoplastic screening protocol, the tested compounds were devoid of activity.

Experimental and Computational Study of the 1,5-O -> N Carbamoyl Snieckus-Fries-Type Rearrangement

The reactions of o-lithiated O-aryl N,N-diethylcarbamates with different C-N multiple bond electrophiles have been thoroughly studied. A 1,5-O -> N carbamoyl shift, a new variation of the anionic Fries-type rearrangement, takes place when nitriles, imines, or alkylcarbodiimides are employed. In these cases, the carbamoyl group plays a dual role as a directing group, building up a variety of functional groups through the 1,5-O -> N carbamoyl migration. On the other hand, the use of iso(thio)cyanates and arylcarbodiimides led to non-rearranged o-functionalized O-arylcarbamates. This reactivity was further computationally explored, and the governing factor could be traced back to the relative basicity of the alternative products (migrated vs nonmigrated substrates). This exploration also provided interesting insights about the degree of complexation of the lithium cations onto these substrates. A new access to useful 2-hydroxybenzophenone derivatives has also been developed.

Lewis Acid Mediated Addition of Indoles and Alcohols to Tetronic Acid and Tetramic Acids

The electrophilic substitution of indoles with tetronic acid and N-acetyltetramic acid mediated by BF3OEt2 was investigated. This strategy allowed for the preparation of nine indole-substituted furan-2-ones (indolyl–lactones) and 3-pyrrolin-2-ones (indolyl–lactams) and is more straightforward than previously reported synthetic methods. During the course of our investigation, we also discovered a facile synthesis of tetronates and a tetramate via a BF3-mediated addition of alcohols to tetronic acid and N-acetyltetramic acid, respectively.
