Description: DETAIIi3D DESCRIPTION OF THE INVENTION This invention relates to a compound having the formula (I) EMI1.1 wherein E is a 2,3,3-triiodoallyl group or a 3-iodopropargyl group; A, B, C and D are individually a nitrogen atom or a carbon atom provided that all of A, B, C and D do not represent nitrogen atoms; and X, Y and Z may be the same or different and represent a hydrogen atom, a chlorine atom, a nitro group, a phenyl group, a 3-chloro2-nitrophenyl group, a methyl goup, a methoxycarbonyl group or an ethoxycarbonyl group, said atom or group being attached to a carbon atom of A, X, C or D, as well as an antimicrobial and-antifungal composition which comprises as an active ingredient at least one of the compound (I). The present inventors previously found a new antibiotic substance SS-208GA (also called pyrrolomycin A) and filed a Japanese Patent Application No. 141123/1980 disclosing and claiming the said antibiotic substance, a process for producing the same and an antifungal composition containing as an active ingredient the said antibiotic substance (See, Japanese Patent Laid-Open Application No. 90099/1981). Since then, the present inventors have made structural modification of pyrrolomycin A by chemical reaction in order to enhance the antifungal activity thereof and, as a result, found out that introduction of triiodoallyl group or iodopropargyl group to the nitrogen atom of the pyrrole ring in the said substance can much more enhance the antifungal-activity thereof. Further, it has been found that derivatives of the triiodoallyl compounds and iodopropargyl compounds having a nitrogen-containing 5membered heterocyclic ring and an antifungal activity can exert remarkable antimicrobial and antifungal activities and then the present invention has been completed upon these findings. The compounds (I), which can be provided according to this invention, are all novel compounds and useful substances having remarkably high antifungal and antimicrobial activities.

EMI5.1 In the schema, A, B, C, D, E, X, Y and Z are as defined above and W is a hydroxy group esterified with sulfonic acid or a halogen atom. Of the starting materials which may be employed in the present invention, triiodoallyl alcohol and iodopropargyl alcohol are well-known compounds and can be prepared by any of known methods, for example, the process as disclosed in Japanese Patent Publication No. 2444/1974. Other starting allyl or propargyl halides or allyl or propargyl esters may be prepared, for example, by reacting triiodoallyl alcohol or iodopropargyl alcohol with a halogenating agent, e.g. thionyl chloride or thionyl bromide to form the corresponding halides or by reaction of the said alcohol with an esterifying agent, e.g. toluenesulfonyl chloride, benzenesulfonyl chloride or methanesulfonic acid anhydride to form tne corresponding esters. Of another starting material (II) wbich may be employed in this invention, 2,3-dichloro-4-nitropyrrole (pyrrolomycin A) and 3-chloro-4- (3' -chloro-2' -nitrophenyl)- pyrrole (pyrrolnitrin) are well-known as fermentative products by microbes, 3-nitropyrrole and 2,3-dichloro4-ethoxycarbonylpyrrole may be synthesized by the processes disclosed in Tetrahedron, 22, 57 (1966) and Canadian Journal of Chemistry, 50,3223 (1972) respectively. Other starting materials may be prepared by those skilled in the art with application of the processes for preparing the aforesaid materials. On the other hand, pyrazole, triazole, tetrazole, 5-methyltetrazole, 5-phenyltetrazole and the like are publicly known and commercially available, while 5acetylaminotetrazole may be readily prepared by acetylation of 5-aminotetrazole. According to the process of this invention, the heterocyclic compound (I) can be prepared by dissolving or dispersing the nitrogen-containing aromatic compound (III) in an inert organic solvent and adding a base and the triiodoallyl or iodopropyne compound (IV) to conduct N-alkylation reaction for introducing a triiodoallyl or iodopropargyl group onto the ring nitrogen atom in the said nitrogen-containing aromatic compound. As examples of the inert organic solvent which may be employed in this invention, there may be mentioned, for example, benzene, dioxane, dichloromethane, N,N-dimethyl- formamide and the like. As examples of the base which may be employed in the present reaction, there may be mentioned, for example, an inorganic base such as an alkali hydroxide, an alkali carbonate and the like and an organic base such as pyridine, triethylamine and the like. The reaction may proceed rapidly at room temperature wherein an alkali hydroxide is employed, but may be effected under cooling, preferably at a temperature of OOC to 5 0C, for preventing side reactions; alternatively, the reaction may be effected by heating to 400C to 60 0C with an organic base. After completion of the reaction, the desired heterocyclic compound (I) may be easily isolated from the reaction mixture by a conventional method, for example, by precipitation with an inert solvent such as water and the like or extraction with an organic solvent such as toluene, ethyl acetate and the like or, if necessary, in combination with a well-known purification method such as a column chromatography over silica gel or recrystallization from an organic solvent. This invention will be more fully illustrated by way of the following Examples and Preparation Examples.
