Abstract: Disclosed is A method of treatment of a disorder or condition where it is desirable to inhibit the growth of cells, or a method of treatment which involves cytostatic therapy by administering an oligopeptidic compound to a subject in need thereof. The oligopeptidic compound is capable of interacting with proliferating cell nuclear antigen (PCNA) The compound comprises a PCNA interacting motif which is: which is: [K/R]-[F/Y/W]-[L/I/V/A/M]-[L/I/V/A/M]-[K/R] (SEQ ID NO. 28). The oligopeptidic compound has 9-70 subunits and at least one signal sequence. The signal sequence is a nuclear localization signal sequence and/or a cell penetrating signal sequence. In the compound a PCNA interacting motif is N-terminal to a signal sequence.

Abstract: Disclosed is an oligopeptidic compound capable of interacting with proliferating cell nuclear antigen (PCNA), wherein the compound comprises a PCNA interacting motif which is: (SEQ?ID?NO.?28) [K/R]-[F/Y/W]-[L/I/V/A/M]-[L/I/V/A/M]-[K/R]; wherein the oligopeptidic compound has 9-70 subunits and comprises at least one signal sequence, wherein the signal sequence is a nuclear localization signal sequence and/or a cell penetrating signal sequence and wherein in said compound a PCNA interacting motif is N-terminal to a signal sequence. Also disclosed are methods of treatment of a disorder or condition where it is desirable to inhibit the growth of cells, or a method of treatment which involves cytostatic therapy, or a method of treatment of inflammation said method comprising administering the oligopeptidic compound to a subject in need thereof.

Abstract: The present invention provides an oligopeptidic compound comprising a PCNA interacting motif, or a nucleic acid molecule comprising a sequence encoding said oligopeptidic compound, for use in therapy, wherein the PCNA interacting motif is X1X2X3X3?X1?- (SEQ ID NO: 1), wherein X1 and X1?- are independently selected from the group of basic amino acids, X2 is a lipophilic amino acid and X3 and X3? are independently selected from the group of uncharged amino acids; and wherein the oligopeptidic compound is further characterized by at least one of the following: (i) the oligopeptidic compound comprises at least one signal sequence; (ii) the PCNA interacting motif is [K/R]-F-[L/I/V]-[L/I/V]-[K/R] (SEQ ID NO: 27). Particularly the therapy may be the treatment of a disorder or condition where it is desirable to inhibit the growth of cells, for example a hyperproliferative disorder, or a treatment which involves cytostatic therapy e.g., myeloablation.
