Oligopeptides that contain phosporus, represented by the formule
in which R, represents hydrogen, lower alkyl, substituted or non substituted phenyl alkyl, or R4CO- (where R4 represents hydrogen, lower alkyl, or substituted or non substituted phenyl alkyl), R2 represents lower alkyl, R3 represents hydrogen, lower alkyl, or substituted or non substituted phenyl alkyl, and Y represents hydrogen or hydroxyl exhibiting a hypertensive activity.
These oligopeptides can be prepared either by synthetic methods or, for two of them (namely antibiotics K-4 and K26), by cultivating microorganisms belonging to the genus ACTINOMADURA SPICULOSOSPORA NOV. SP K-4 (Ferm P-6101) and ACTINOMYCES K-26 (FERM P-5889, NRRL 12379) respectively.
含磷的低聚肽,由以下形式表示
其中 R 代表氢、低级烷基、取代或未取代的苯基烷基或 R4CO-(其中 R4 代表氢、低级烷基、取代或未取代的苯基烷基),R2 代表低级烷基,R3 代表氢、低级烷基、取代或未取代的苯基烷基,Y 代表氢或羟基,具有高血压活性。
这些寡肽既可以通过合成方法制备,也可以通过培养属于 ACTINOMADURA SPICULOSOSPORA NOV.SP K-4(Ferm P-6101)和 ACTINOMYCES K-26(FERM P-5889,NRRL 12379)。
