Cycloheximide and Other Glutarimide Antibiotics,cyclohexanone nucleus attached to position 4 of the glutarimide ring through a twocarbon bridge. The individual compounds differ either in substitution or in the degree of unsaturation of the dimethylcyclohexanone nucleus (., 1964; . and ., 1964). The cycloheximide molecule has four assymetric centr

Nystatin,. It is unique, however, in that much of what is known of the structure is due to biosynthetic investigations. The macrolides are characterised by many-membered lactone rings, carrying numerous substituents: methyl groups, hydroxyl groups, unusual sugar, and frequently at least one carbonyl group. T

Synthetic vs Analytic Geometry for Computersexcretion of these highly efficient and selective iron chelators originated as an evolutionary response of organisms to overcome iron deficiency (., 1957). Most naturally occurring hydroxamates exhibit striking biological activity. Certain hydroxamates, such as ferri-chrome, are potent growth factor
