Neooxaline has been obtained (80CPB2987) from Aspergillus japonicus and identified as 231 (undefined stereochemistry). With acetic anhydride in DMSO, it gave mainly 232 which, on alkaline hydrolysis, gave 230. Compound 230, like oxaline, with diazomethane gave 14-methyloxaline. 

Neoxaline, C23H25N5O4, a new metabolite of Aspergillus japonicus, exhibits similarities to oxaline in its i.r. and n.m.r. spectra, and may be an indole derivative, but nothing further is known of its constitution as yet.38a Similarly, three new tremorgenic mycotoxins from Penicillium janthinellum, janthitrems A, B, and C, may also be indole derivatives.386... 

Neoxaline (26), the metabolite of Aspergillus japonicus,l4b proves, as expected, to be very closely related to oxaline (27). Oxidative acetylation of neoxaline by means of DMS0-Ac20 gave an enol acetate (28), which, on hydrolysis followed by methylation, gave 14-methyloxaline (29), identical with the methylation product (by CH2N2) of oxaline.26... 

Neoxaline (145) has been isolated from Aspergillus japonicus (185). It has... 

Although 2,3 QD has been isolated from several fungal species,the enzyme from Aspergillus japonicus has been extensively characterized and will be described herein. A partially deglycosylated form of 2,3QD from A. japonicus has been crystallized in its resting form and in anaerobic complexes with substrates or metal chelators. The enzyme fold is shown in Figure 9. Each 2,3QD monomer... 

Ishii and Yokotsuka recently used pectin lyases from Aspergillus sojae 170, 171, 172) and Aspergillus japonicus (173) for the enzymatic clarification of fruit juices. This is discussed later in this review. Bush and Codner 174) compared the pectin lyases produced by Penicillium digi-tatum and Penicillium italicum and found them remarkably similar. Both were endo acting, had optimal activities at pH 5.5, and had the same K. The pectin lyase from F. italicum, however, was less stable than that of F. digitatum. Spalding and Abdul-Baki 175) reported the production of a pectin lyase by Penicillium expansum growing on apple tissue or a pectin-polypectate mixture. 

Recently, the crystal structure of 2,3QP from Aspergillus japonicus has been determined at a resolution of... 

Ishii (1981) has reported that a purified endo-polygalacturonase from Aspergillus japonicus solubilizes 95% of the total uronides from potato discs. After purification, three polymers were obtained of which the first two appeared to be Rhamnogalacturonans substituted with linear arabinans and galactans. The third fraction was highly branched and... 

Finally, chance observation led to the isolation of new paralytic compounds, asperparalines A, B, and C, from Aspergillus japonicus ATCC 204480. Asperparalines have unique structures consisting of a bicyclo[2,2,2]diazaoctane core and a spiro-succinimide moiety. 

The hint, which led us to this finding, was the accidental observation of paralytic syndrome in silkworms that had digested an extract of a certain isolate. We had been screening numerous soil isolates for their insecticidal activity against silkworms upon oral administration in the usual manner. It was of great interest that the strain Aspergillus japonicus Saito JV-23 resulted in paralysis in silkworms.
