Antibiotic NK86-0279, process for production of the same and application

This invention relates to an antibiotic NK130119 of the formula: ##STR1## which exhibits antifungal, antitumor, vascularizations-inhibitory and insecticidal activities.

Novel antibiotic NK130119

The compounds used in the present invention are represented by the following formula: ##STR1## where X represents hydrogen atom, chlorine atom, bromine atom, methyl group or nitro group, Y represents hydrogen atom, methyl group, an alkylcarbonyl group where the alkyl group has from 1 to 12 carbon atoms, preferably, from 1 to 3 carbon atoms and may be substituted by one or more halogen atoms, a lower alkoxy carbonyl group, a lower alkylamino carbonyl group or a metal atom of which the valence is 1 or 2, Z represents hydrogen atom or chlorine atom and n represents 2 when Y represents a divalent metal and n represents 1 when Y does not represent a divalent metal. Such compounds are employed to control the growth of bacteria, fungi and algae which propagate on industrial raw materials and products or in water in circulating water systems, and to exterminate bacteria and fungi which harm agricultural and horticultural plants or crops.

Compositions and methods for controlling the growth of bacteria, fungi

A new compound represented by the formula ##STR1## WHEREIN X represents hydrogen atom, chlorine atom, bromine atom, methyl group or nitro group, Y represents hydrogen atom, methyl group, an alkylcarbonyl group where the alkyl group has from 1 to 12 carbon atoms and may be substituted by one or more halogen atoms, a lower alkoxy carbonyl group, a lower alkylamino carbonyl group or a metal atom of which the valence is 1 or 2, Z represents hydrogen atom or chlorine atom and n represents 2 when Y represents a metal atom of which valence is 2 and n represents 1 when Y represents said group or said atom except a metal atom of which valence is 2 but when X and Z represent hydrogen atom, Y does not represent hydrogen atom or a metal atom is employed to control the growth of bacteria, fungi and algae which propagate on industrial raw materials and products or in water in circulating water systems.
