摘要:
A compound of the formula or its pharmaceutically acceptable salt: where, in one example. R' is n-octanoyl, n is the integer O, R 2 is benzyl, R 3 is 1-carboxyethylammo, R 4 is hydrogen and R 5 is hydrogen and processes for their preparation and also a pharmaceutically composition comprising, as an effective ingredient, the above compound in association with pharmaceutically acceptable carriers.
摘要:
This invention relates to the new peptide of the general formula:
More particularly, this invention relates to this new peptide and the pharmaceutically acceptable salt thereof, which have pharmacological activities, to processesforthe preparation thereof and to a new intermediate for preparing the active peptide, and to the pharmaceutical composition comprising the same and a method of use thereof.

摘要:
A lactyl tetrapeptide of the formula can be prepared by conventional peptide synthesis. One isomer, FR 900156, is obtained by cultivation of a suitable Streptomyces strain such as Str. violaceus ATCC 31481 or Str. olivaceogriseus ATCC 31427. The invention also relates to a pharmaceutical composition comprising, as an effective ingredient, the above compound in association with a pharmaceutically acceptable, substantially non-toxic carrier or excipient.
