Unclassified Metabolites 



1184 Lenamycin, C4H^0;^No or C4H40._.No (proposed), colorless crys- 



tals, m.p. 202-207° (dec.) optically inactive. 



Apparently an a,/?-unsaturated amide. Negative nin- 

 hydrin, biuret, anthrone, FeCl^, Sakaguchi, Elson-Morgan, 

 nitro and oxime tests. 



A streptomycete 



The yield was 72 mg. from 5 1. of broth. Occurs to- 

 gether wdth fra ns-cinnamic acid amide and ethoxyethene- 

 1 ,2-dicarboamide. 



Yasuharu Sekizawa, /. Biochem. (Japan) 45 159 (1958). 



1185 Lenzitin, colorless needles, m.p. 166°. 



Contains C, H, O only. Positive FeClg, KMn04. 



Lenzites sepiaria (Wulf) 



M. Litvinov and E. Moiseeva, Priroda 1 60 (1951). 



1186 Litmocidin, m.p. 144-146° (dec). 



An acid-base indicator. Decolorized by bisulfite or zinc 

 dust, color restored by air oxidation. 



Proactinomyces cyaneus var. antibioticiis 



G. F. Cause, /. Bacteriol. 51 649 (1946). 



M. G. Brazhnikova, ibid. 51 655 (1946). (Isolation) 



1187 Longisporin, CgeHsgOio, crystals, m.p. 99-101°, [ajo -f2.62°. 



Alkaline hydrolysis yields a hydroxy acid C^oHi60(OH) 

 (COOH). It was suggested that the antibiotic is a cychc 

 ester of three such acid units.
