Actinomycine, XXIV; Antibiotica aus Actinomyceten, XLVIII. Actinomycin X1a und X

Abstract: Aus Actinomycingemischen vom Typ X wurden Actinomycin XI,, &, . und Xoa abgetrennt. -Actinomycin XI, ist das zweite Actinomycin, das y-0x0prolin enthalt. -Durch Reduktion mit Aluminiumisopropylat wurde aus Actinomycin XI, das bisher unbekannte Actinomycin X, gewonnen. -Vergleichende Teste zeigten, wieweit die antibiotisch wirksame Grenzkonzentration der X-Actinomycine von der Struktur ihres Peptidteils abhtingt.Die zur Actinomycin-Synthese befiihigten Streptomyces-Arten konnen die Peptidstruktur ihrer Actinomy… Show more

“…Received January 12,1972 In a previous paper of this series1 it was shown that whereas profadol (I, R = H; R' = Pr; R" = Me) exhibited a high level of analgetic activity, replacement of the A-methyl group with JV-n-propyl afforded an analog that was inactive in the rat tail pressure test. There was a similar fall off in analgetic activity in the O-methyl analogs on increasing the chain length of R" from methyl, through ethyl, to n-propyl (i.e., I, R = Me; R' = Pr; R" = Me, Et, or Pr).…”

“…Actinomycins Av, (129) and By are known to be identical with X2 (275). In actinomycin Xia one peptide has sarcosine in place of L-proline and the other has 4-keto-L-proline in place of L-proline (42).…”
