Abstract
Antibiotic U-43,795, producible by culturing Streptomyces sviceus in an aqueous nutrient medium has the following structure ##EQU1## The absolute configuration of U-43,795 was determined to be .alpha.S, 4S, 5R .alpha.-amino-3-chloro-4-hydroxy-2-isoxazoline-5-acetic acid. It is an amphoteric compound and can exist in different ionic forms according to the pH of the environment. At low pH, U-43,795 exists in the acid-addition salt form, at a higher pH in a zwitterion form, and at still higher pH in a metal salt form. U-43,795 inhibits the growth of Bacillus subtilis and Sarcina lutea, and can be used to inhibit such microorganisms in various environments.
