Abstract

WHEREIN X represents -CH3 or -O-CH3. These agents are extracted from the growth of Spicaria divaricatum NRRL 5771. The compound wherein X is -CH3 is particularly active in inhibiting the growth of fungi, bacteria, viruses, and in addition is an effective anti-desoxycorticosterone acetate (DCA) agent.
The present invention is concerned with the microbial production of anti-microbial product and anti-microbial agents of the formula

Claims

1. A PROCESS FOR PRODUCING AN ANTI-MICROBIAL PRODUCT COMPRISING GROWING SPICARIA DIVARICATA NRRL 5771 IN AN AQUEOUS NUTRIENT MEDIUM, EXTRACTING SAID AQUEOUS NUTRIENT MEDIUM CONTAINING SPICARIA DIVARICATA NRRL 5771 WITH ORGANIC SOLVENT TO PROVIDE ORGANIC SOLVENT EXTRACTS, SEPARATING SAID ORGANIC SOLVENT EXTRACTS FROM SAID AQUEOUS NUTRIENT MEDIUM CONTAINING SPICARIA DIVARICATA NRRL5771, AND EVAPORATING THE ORGANIC SOLVENT.

2. THE ANTI-MICROBIAL PRODUCT PRODUCED BY THE PROCESS OF CLAIM 1.

3. THE PROCESS OF CLAIM 1, WHEREIN THE ANTI-MICROBIAL PROUCT OF CLAIM 1 IS SUBJECTED TO COLUMN CHROMATOGRAPHY TO PROVIDE COMPOUNDS OF THE FORMULA

4. The compound produced by the process of claim 3, which compound is 3-(2-oxopropyl) 3'"'"''"'"'-methylcarboxymethyl-3,3'"'"''"'"',4,4'"'"''"'"'-tetrahydro-9,9'"'"''"'"',10,10'"'"''"'"'-tetrahydroxy-7,7'"'"''"'"' -dimethoxy-1,1'"'"''"'"'-dioxo-8, 8'"'"''"'"'-Bi-1H-naphtho(2,3-c)pyran.
