Synthesis and antimicrobial activity of pyrimidinyl bis(benzazoles)

A new class of pyrimidinyl bis(benzoxazoles/benzothiazoles/benzimidazoles) linked by amino sulfamido moieties were prepared and tested for antimicrobial activity. The bis(benzazolyl)pyrimidines (9, 10) displayed higher activity than the corresponding azolyl pyrimidines (4?7). In fact, bis(benzimidazolylamino)pyrimidinylsulfamide (9c), bis(benzothiazolylmethylamino)pyrimidinylsulfamide (10b), bis(benzimidazolylmethylamino)-pyrimidinylsulfamide (10c) were found to be potential antimicrobial agents against S. aureus and P. chrysogenum.

A new bacterial L-amino acid oxidase with a broad substrate specificity: Purification and characterization

The Gram-positive bacterium Rhodococcus opacus DSM 43250 produces an L-amino acid oxidase (L-AAO) with a very broad substrate specificity. This enzyme has been purified to homogeneity and a detailed biochemical characterization was carried out. The complete nucleotide sequence of the L-AAO gene was determined and the primary structure of L-AAO was deduced. The molecular mass of the native enzyme was 99kDa determined by gel filtration, 54.2/108.5kDa measured by MALDI-TOF/MS, 53.2kDa for the subunit calculated after SDS/PAGE. The coenzyme-binding motif G-X-G-X-X-G which is known for all L-AAOs was found very close to the N-terminus of the protein. L-AAO oxidized 39 out of 43 tested L-amino acids. The kinetic data for 16 of these L-amino acids were determined revealing Km-values in the range of 15-30muM for substrates like L-phenylalanine, L-leucine, L-citrulline and L-lysine. The stability of L-AAO can be increased by storage or incubation of the enzyme in glycine/NaOH buffer. The protein has a pI of 4.8 and a slightly basic pH-optimum at pH 8-9 measured for L-alanine, L-phenylalanine and L-leucine as substrates. The ability for resolution of racemic mixtures was investigated and D-amino acids with an enantiomeric excess of >99% were obtained.

Cu-catalyzed Asymmetric Dearomative [3 + 2] Cycloaddition Reaction of Benzazoles with Aminocyclopropanes

The enantioselective dearomative [3 + 2] cycloaddition reaction of benzazoles with aminocyclopropanes has been successfully developed. In the presence of a copper complex, derived from Cu(OTf)2 and bisoxazoline, a series of hydropyrrolo-benzazole derivatives containing quaternary stereogenic centers were obtained in high yields with excellent enantioselectivity. This method could also provide 2-amino cyclopropanes with high enantiomeric purity by an efficient kinetic resolution. In addition, products could be transformed to pyrrolo-benzothiazines and 1,5-benzothiazepines. Chiral compounds are of great significance in many areas given that two corresponding enantiomers could have completely different properties in chiral environments. Therefore, technologies used to produce chiral compounds in their enantiopure form are particularly attractive and highly desirable. Catalytic asymmetric dearomatization reactions have become efficient methods for the construction of chiral fused- or spiro-heterocycles from simple aromatics. Polyheterocyclic structures containing a hydropyrrolo-azole motif are found extensively in natural products and biologically active compounds. Therefore, efficient methods for constructing complex chiral hydropyrrolo-azole compounds will benefit the lead identification in drug discovery. Herein, we report the highly enantioselective construction of hydropyrrolo-benzazoles via copper-catalyzed dearomative [3 + 2] cycloaddition of benzazoles with donor-acceptor aminocyclopropanes. Heterocycles are a very important class of compounds that exist extensively as structural cores in natural products and biologically active molecules. Catalytic asymmetric dearomatization (CADA) is an efficient strategy for the construction of chiral fused- or spiro-heterocycles from simple planar aromatic compounds. Herein, we report the development of enantioselective dearomative [3 + 2] cycloaddition reactions of benzazoles with aminocyclopropanes via kinetic resolution. In the presence of a copper complex, derived from Cu(OTf)2 and bisoxazoline, a series of hydropyrrolo-benzazole derivatives containing quaternary stereogenic centers were obtained in high yields (up to 99%) with excellent enantioselectivity (up to 99% enantiomeric excess [ee]). With the same catalytic system, 2-amino cyclopropane-1,1-dicarboxylates with a high enantiomeric purity (up to 98% ee) were also obtained by an efficient kinetic resolution (s values of up to 95). In addition, the utility of this method was showcased by the facile transformation of products into several important heterocyclic frameworks, including pyrrolo-benzothiazine and 1,5-benzothiazepine.
