| abstract | 1,225,132. Tsushimycin; hydrogenated tsushimycin. SHIONOGI & CO. Ltd. 3 Oct., 1968 [4 Oct., 1967; 7 Oct., 1967], No. 46992/68. Heading C2A. A new antibiotic, tsushimycin, effective in inhibiting the growth of gram-positive microorganisms, is a colourless, amphoteric amorphous powder having an isoelectric point at about pH 3, m.p. 230-240‹ C. (decomp.), containingthe elements C, H, O and N in the weight percentages C=49.48, H=7.53, N=12.76 and water=7.39; an optical rotation of [α]<SP>23</SP> D + 12.9‹Œ0.5‹ (C=0.981% in MeOH), a molecular weight of about 1400 and a neutralization equivalent of 445 and the I.R. spectrum shown in Fig. 1, is prepared by cultivating a tsushimycin-producing strain of Streptomyces pseudo griseolus in an aqueous nutrient medium under aerobic conditions and recovering the antibiotic. Hydrogenated tsushimycin having an isoelectric point at about pH 3, melting at 233- 243‹ C. (decomp.), containing C, H, O and N in the weight percentages C=48.76, H=7.72, N=12.40 and water=9.86; having a specific rotation of [α]<SP>23</SP> D + 14.1‹ Œ 0.5‹ (C=0.944% in MeOH) and having the I.R. spectrum shown in Fig. 2, is prepared by catalytically hydrogenating tsushimycin. |
