    摘要： The invention deals with novel peptides useful for the therapeutic treatment of infectious diseases caused by pathogenic microorganisms. Included is the peptide FR900156 having the structure: ##STR1## as well as the peptides of the structure ##STR2## wherein R.sup.1 is acyl;R.sub.b.sup.1 is hydrogen, methyl, isopropyl, hydroxymethyl, protected hydroxymethyl or benzyl;R.sup.2 is hydrogen, carboxy, protected carboxy, or a group of the formula: ##STR3## wherein R.sub.a.sup.2 is mono- or di-carboxy lower alkyl or ar(carboxy) lower alkyl whose aryl moiety may be substituted by hydroxy,R.sub.b.sup.2 is hydrogen or lower alkyl;R.sup.p and R.sup.q are each hydrogen, carboxy, protected carboxy, with proviso that when one of R.sup.2 and R.sup.q is hydrogen, then the other is carboxy or protected carboxy;R.sup.r is hydrogen or amino protective group; m is an integer 1 to 3; and n is 1 provided that when R.sup.1 is hydrogen, t-butoxycarbonyl or N-acetylmuramyl, R.sub.b.sup.1 is methyl, m is an integer 2 and n is an integer 1, then R.sup.2 is hydrogen, protected carboxy or a group of the formula: ##STR4## wherein R.sub.a.sup.2 is mono- or di-carboxy lower alkyl having 1 and 3 to 6, carbon atoms, .alpha.-carboxyethyl, ar(carboxy) lower alkyl whose aryl moiety may be substituted by hydroxy and R.sub.b.sup.2 is as defined above, or its pharmaceutically acceptable salt.
