Resolution and assignment of the absolute stereochemistry of a trans-2,3-diarylpyrrolidine LTB4 inhibitor intermediate

1,3-Cycloaddition of an azaallyl anion with 4-methoxystyrene furnishes the corresponding racemic trans-pyrrolidine. Resolution of both enantiomers was accomplished by fractional crystallization with the inexpensive diacetone-2-keto-L-gulonic acid. The absolute stereochemistry was determined by single crystal X-ray analysis of the corresponding sulfonamide.

Synthesis of 5H-Benzoxazolo<3,2-a>quinazolin-5-ones

5H-Benzoxazolo<3,2-a>quinazolin-5-ones (Xa-d) were synthesized in excellent yields from N-(2-hydroxyphenyl)anthranilic acids (Ia-d) and cyanogen bromide.The synthesis was based on the mechanistic consideration of the reactions of salicylic acid with cyanogen bromide previously reported in the literature.A versatile alternative route to these novel heterocyclic compounds was through thermal cyclization of N-(2-benzoxazolyl)-2-fluorobenzamides (XIII) obtained by reacting 2-fluorobenzoyl chloride with 2-aminobenzoxazoles.The reaction of Xb with ethanol in the presence of potassium hydroxide gave an ethoxyquinazolinone (XVII).Similarly, the alkaline hydrolysis of Xb afforded an quinazolindione (XVIII).

Identification of 1-[4-benzyloxyphenyl)-but-3-enyl]-1H-azoles as new class of antitubercular and antimicrobial agents

A series of 1-[(4-benzyloxyphenyl)-but-3-enyl]-1H-azoles has been identified as potent antitubercular agents against Mycobacterium tuberculosis. Synthesis of compounds involved acid catalyzed ring-opening of cyclopropyl ring of phenyl cyclopropyl methanols followed by nucleophilic attack of the azoles on the carbocation intermediates. Several of the compounds 26, 34, and 36 exhibited significant antitubercular activities with MIC value as low as 1.56, 1.56, and 0.61 mug/mL, respectively, comparable to many standard drugs. These compounds were also screened against other strains of bacteria and fungi, and few of them showed good antifungal activity against A. fumigatus, responsible for lung infection.

Combining Mass Spectrometric Metabolic Profiling with Genomic Analysis: A Powerful Approach for Discovering Natural Products from Cyanobacteria

An innovative approach was developed for the discovery of new natural products by combining mass spectrometric metabolic profiling with genomic analysis and resulted in the discovery of the columbamides, a new class of di- and trichlorinated acyl amides with cannabinomimetic activity. Three species of cultured marine cyanobacteria, Moorea producens 3L, Moorea producens JHB, and Moorea bouillonii PNG, were subjected to genome sequencing and analysis for their recognizable biosynthetic pathways, and this information was then compared with their respective metabolomes as detected by MS profiling. By genome analysis, a presumed regulatory domain was identified upstream of several previously described biosynthetic gene clusters in two of these cyanobacteria, M. producens 3L and M. producens JHB. A similar regulatory domain was identified in the M. bouillonii PNG genome, and a corresponding downstream biosynthetic gene cluster was located and carefully analyzed. Subsequently, MS-based molecular networking identified a series of candidate products, and these were isolated and their structures rigorously established. On the basis of their distinctive acyl amide structure, the most prevalent metabolite was evaluated for cannabinomimetic properties and found to be moderate affinity ligands for CB1.
