A Kähler-Chern-Simons Theory And Quantization Of Instanton Moduli Spaces, V. P. Nair, Jeremy Schiff Mar 1990

A Kähler-Chern-Simons Theory And Quantization Of Instanton Moduli Spaces, V. P. Nair, Jeremy Schiff

Publications and Research

A five dimensional field theory is introduced which is an analogue of three dimensional Chern-Simons theory. The reduced phase space in the theory is a moduli phase of instantons in four dimensional Euclidean gauge theory, with a symplectic structure induced by the Donaldson u-map. Issues related to quantization are discussed.

Biological Activity And Conformational Analysis Of Nikkomycins And Their Analogs, Eduardo Krainer Jan 1990

Biological Activity And Conformational Analysis Of Nikkomycins And Their Analogs, Eduardo Krainer

Dissertations, Theses, and Capstone Projects

Nikkomycins and polyoxins are peptidyl nucleoside antibiotics produced by Streptomyces species. They are potent inhibitors of chitin synthetases from pathogenic fungi, and polyoxins have been used in Japan for many years as agricultural fungicides and for insect control. Since chitin synthetase is not found in mammals and both families of antibiotics are not toxic, these inhibitors are potentially attractive for clinical use. Unfortunately these compounds seem to have only a fungistatic action, and they are not used clinically at present.

A procedure for efficiently obtaining nikkomycins X and Z of very high purity from crude antibiotic is described. These nikkomycins …
