    摘要: A compound of the formula ##STR1## wherein R is .beta.-D-glucopyranosyl, .beta.-D-galactopyranosyl, 6'-O-acetyl-.beta.-D-glucopyranosy or 6'-O-acetyl-.beta.-D-galactopyranosyl, or a pharmaceutically acceptable salt thereof, has bronchodilator, cardiac activity, smooth muscle relaxant activity and hormone excretion stimulant activity. It can be produced by culturing a microorganism belonging to the genus Nodulisporium and adapted to produce the compound in a culture medium, and isolating the produced compound from the cultured medium. The microorganism can be Nodulisporium sp. M5220 FERM P-8133. The compounds have inhibitory activity on cyclic-adenosine-3',5'-monophosphate phosphodiesterase.

    摘要: A group of sulfur-containing antibiotics, planothiocin-A, -B, -C, -D, -E, -F and -G, are produced by culturing Actinoplanes sp. A12526 in a nutrient medium, and separating the thus-produced planothiocins therefrom. The novel antibiotics have utility in therapeutic or prophylactic antibacterial compositions or feed additives for livestock, poultry or fish.

    摘要: Neplanocin A derivatives of the formula ##STR1## wherein R.sub.1 and R.sub.2 are hydrogen or benzoyl, R.sub.3 is hydrogen or OR.sub.8, R.sub.5 is hydrogen or acetyl, R.sub.6 is hydrogen, acetyl or benzoyl, when R.sub.3 is hydrogen, R.sub.4 is hydrogen or halogen, hydroxy, acetoxy, acetylthio, amino or azide, and when R.sub.3 is OR.sub.8, R.sub.4 is hydrogen, R.sub.8 is hydrogen or acetyl, or R.sub.8 and R.sub.5 together form benzylidene, and at least one of R.sub.8, R.sub.5 and R.sub.6 is other than hydrogen. The compounds of the present invention have inhibitory action for the growth of L 5178 Y cells and have the same or superior activity as neplanocin A, and hence are useful as antitumor agents.
