Abstract: 1,270,637. Antifungal agents BK.217# and BK.217γ. AMERICAN CYANAMID CO. 10 April, 1970, No. 17275/70. Heading C2A. The novel antifungal antibiotics BK.217# and BK.217γ, produced by aerobically cultivating Streptoverticillium cinnamoneus (NRRL.3594), are characterized as follows: Both components # and γ are microcrystalline solids containing the amino-sugar, mycosamine; they give a positive response to the Molisch and 2,4-dinitrophenylhydrazine colour tests, are negative to ninhydrin, and in c. H 2 SO 4  BK.217# gives a violet coloration changing to brown and BK.217γ gives a blue coloration changing to violet. The fermentation is conducted in conventional aqueous medium, usually liquid with deep aeration and agitation, containing assimilable sources of carbon and nitrogen, preferably with inorganic ions such as those of Ca, K, Na, SO 4 , PO 4  and Cl. The antibiotics are isolated from the culture by filtering, washing the mycelium with CHCl 3  and then extracting it with methanol, concentrating the wet methanol to an aqueous phase and collecting and drying the precipitate of crude BK.217# and BK.217γ. The components are separated by extracting the solid with methanol, precipitating the supernatant with ether and purifying the precipitate e.g. by column chromatography on dextran gel or counter-current distribution to yield pure BK.217#. The insoluble residue from the methanol extraction is purified by dissolving in methanol/CHCl 3  and subjecting to countercurrent distribution. Pharmaceutical compositions comprise one or both of the antifungal antibiotics BK.217# and BK.217γ and an acceptable diluent or carrier. They may be in oral or parenteral forms, e.g. tablets, hard capsules, an oral suspension or a sterile injectable suspension.

Abstract: The invention comprises compounds of the general formula: <FORM:0855115/IV(b)/1> (wherein Y is S, O, or SO2, R1 is hydrogen, hydroxy, fluorine, chlorine, bromine, nitro, trifluoromethyl, lower alkyl or lower alkoxy, in position 5 or 6, R2 is lower alkyl and Z is amino, mono lower alkylamino, di-lower alkylamino, cyclopentylamino, cyclohexylamino, N-piperidino or N-pyrrolidino) and their non-toxic acid addition salts and methods for their preparation.  The general method involves condensation of a 2- or 3-halomethyl-R1-substituted benzofuran or thianaphthene with a diethyl a -alkyl malonate, hydrolysis of the resulting diethyl a -alkyl-a -thianaphthyl (or benzofuryl) methyl malonate, decarboxylation to the corresponding propionic acid derivative, conversion via the acid chloride and azide to the corresponding isocyanate followed (a) by heating with concentrated H Cl to yield the b -aminoalkyl thianaphthene or benzofuran, or (b) by reduction with lithium aluminium hydride to yield the analogous b -methylaminoalkyl compounds.  The amino compounds are alkylated if desired by conventional methods.  The S-dioxides are obtained by treatment with excess hydrogen peroxide, protecting primary amino groups by acetylation prior to oxidation. Detailed examples are given.  The 3-halomethylthianaphthene intermediates are prepared from R1 substituted thiophenols by condensation with chloroacetone, cyclization and halogenation of the resulting 3-methyl-R1-substituted thianaphthene.  The corresponding 2-halomethyl compounds are formed from the R1-substituted thianaphthene by treatment with butyl lithium and then formaldehyde followed by reaction of the 2-hydroxymethylthianaphthene with a halogenating agent.  The 3-halomethylbenzofuran intermediates are prepared by bromination of 3-methylbenzofuran followed by debromination of the 2-bromo-3-bromomethylbenzofuran at position 2 preferably at a later stage of the synthesis.  The analogous 2-halomethylbenzofurans are formed by reduction of a coumarilic acid and then halogenation of the 2-hydroxymethylbenzofurans so obtained.
