Structure Elucidation of Antibiotics

2022
To date, there are hundreds of characterized natural products with antibacterial activity against pathogenic bacteria, and several have become bonafide antibiotic drugs. The development of antibacterial natural products into antibiotic drugs, both in the past and in the future, hinges upon an accurate description of the exact chemical structure of the ...

The Structure Elucidation of Pseudothiocolchicine

Helvetica Chimica Acta, 1985
AbstractA colchicine derivative, previously isolated from the reaction of isocolchicine with sodium thiomethoxide in aqueous MeOH, was now identified as 11‐(methylthio)isocolchicine on the basis of 1H‐, 13C‐NMR spectra and chemical correlation. This reaction represents the first example of abnormal nucleophilic displacement (telesubstitution) in the ...

Computer-assisted structure elucidation

Fresenius' Zeitschrift für analytische Chemie, 1982
Program case, an evolving computer model of the structure elucidation process, treats three major tasks: reduction of chemical and spectral properties to their structural implications, generation of complete molecular structures compatible with the structural features identified, and ranking these structures by comparing predicted and observed spectral

Structural Elucidation of Complex Carbohydrates

1988
Many current problems in immunology depend on a detailed understanding of oligosaccharide and glycoconjugate structures. In contrast to other biopolymers, oligosaccharides do not have well established and sensitive analytical procedures for the determination of their structures.
