This invention provides processes for producing quinolone compounds which comprise cultivating Amycoa sp. FERM BP-4785, and then isolating quinolone compounds from the fermentation broth. The compounds produced by these processes include compounds of formula (I) wherein R.sup.1 is H, R.sup.2 is (a) and R.sup.3 is CH.sub.3 ; R.sup.1 is CH.sub.3, R.sup.2 is (a) and R.sup.3 is CH.sub.3 ; or R.sup.1 is CH.sub.3, R.sup.2 is (b) and R.sup.3 is CH.sub.3 ; and the like. The present invention also relates to a pharmaceutical composition comprising the same, which is useful in the treatment of diseases, disorders and adverse conditions caused by Helicobacter pylori and is particularly useful in the treatment of gastroduodenal disorders, diseases and adverse conditions caused thereby. ##STR1##
摘要:
This invention provides compounds of the following chemical formula or their pharmaceutically-acceptable salts: ##STR1## wherein R is hydrogen or chloro. Also, the present invention provides a process for the production of the compound of formula I, which comprises cultivating a microorganism having the identifying characteristics of Aspergillus fischeri var. thermomutatis ATCC 18618 or the like, and then isolating the compound of formula I from the fermentation broth. The pyrrolobenzoxazine compounds of formula I of this invention have broad antiparasitic activity, and thus are useful as antiparasitic agents, especially as anthelmintics.

摘要:
The present invention provides a novel culture which belongs to Actinoplanes (Actinoplanes sp. FERM BP-3832). This culture is capable of producing rapamycin more than ten times efficiently than the cultures which have been reported (e.g., Streptomyces hygroscopicus ATCC 29253). The present invention provides a process for the production of rapamycin which comprises cultivating Actinoplanes sp. FERM BP-3832 and thereafter isolating rapamycin from the fermentation mixture.
摘要:
An antibiotic compound of the formula: ##STR1## is an antiparasitic agent active against insect pests, acari, free living nematodes and endo- and ectoparasites. It is prepared by fermentation using the microorganism Streptomyces griseochromogenes ATCC 53928.
摘要:
A technique with which a change in power frequency can be suppressed. A power system stabilizer issues a control command to a first storage battery among a plurality of first power generators and the first storage battery that are connected to an isolated island system via a first tie-line. The power system stabilizer includes a parameter determination unit and a control block unit. The parameter determination unit obtains, on the basis of operation information, a rate-of-change limit value that indicates a limit to be imposed on a total value of changes in the overall output of first power generators in operation. The control block unit generates a command value to be given to the first storage battery on the basis of an interconnection point power flow value measured on the first tie-line and the rate-of-change limit value obtained by the parameter determination unit.
摘要:
A locking mechanism of a seat for a vehicle, the seat including a seat back and a seat base, the locking mechanism including a recliner that reclines the seat back and locks the seat back in a position, the recliner and a memory ring being located on the axis, and when the memory ring is held relative to the recliner the seat back returns to an original position when the seat back travels in a forward direction from the original position past an upright position and then moves in a rearward direction back to the original position.
摘要:
A stopper includes an attachment portion and a pair of flanges. The attachment portion contacts an outer surface of a bottom wall portion of a lower rail and is attached to the bottom wall portion. The flanges extend from the attachment portion to be passed through insertion holes in the bottom wall portion. The flanges are located in an inner space of the lower rail. The flanges are engaged with second cut-and-raised pieces formed in an upper rail, thereby limiting the range of movement of the upper rail relative to the lower rail.
