Abstract
Described are peptides and peptide mimetics that bind to and the IL-5 receptor. Such peptides and peptide mimetics are useful in methods for treating disorders that involve improper production of or response to IL-5 and or the production and accumulation of eosinophils, such as asthma, as well as in diagnostic methods employing labeled peptides and peptide mimetics.
Claims15
A method for treating a patient suffering from a disorder that is mediated by IL-5, comprising administering to the patient, a therapeutically effective dose of a compound comprising:
- (1) a core sequence of amino acids:
- C X.sub.1 X.sub.2 W X.sub.3 R C X.sub.4 X.sub.5 C
- where X.sub.1 is G, I, V, or Y;
- X.sub.2 is D or E;
- X.sub.3 is A or V;
- X.sub.4 is Q or P;
- and X.sub.5 is A, E, K, M, N, S, or T (SEQ ID NO:1), and dimers and oligomers thereof, having
- (a) a molecular weight of less than about 5000 daltons, and
- (b) a binding affinity to IL5-R as expressed by an IC.sub.50 of no more than about 100 .mu.m,
- wherein from zero to all of the --C(O)NH-- linkages of the peptide have been replaced by a linkage selected from the group consisting of a --CH.sub.2 OC(O)NR-- linkage;
- a phosphonate linkage;
- a --CH.sub.2 S(O).sub.2 NR-- linkage;
- a --CH.sub.2 NR-- linkage;
- and a --C(O)NR.sup.6 -- linkage;
- and a --NHC(O)NH-- linkage where R is hydrogen or lower alkyl and R.sup.6 is lower alkyl,
- further wherein the N-terminus of said peptide or peptide mimetic is selected from the group consisting of a --NRR.sup.1 group;
- a --NRC(O)R group;
- a --NRC(O)OR group;
- a --NRS(O).sub.2 R group;
- a --NHC(O)NHR group;
- a succinimide group;
- a benzyloxycarbonyl--NH-- group;
- and a benzyloxycarbonyl--NH-- group having from 1 to 3 substituents on the phenyl ring selected from the group consisting of lower alkyl, lower alkoxy, chloro, and bromo, where R and R.sup.1 are independently selected from the group consisting of hydrogen and lower alkyl,
- and still further wherein the C-terminus of said peptide or peptide mimetic has the formula --C(O)R.sup.2 where R.sup.2 is selected from the group consisting of hydroxy, lower alkoxy, and --NR.sup.3 R.sup.4 where R.sup.3 and R.sup.4 are independently selected from the group consisting of hydrogen and lower alkyl and where the nitrogen atom of the --NR.sup.3 R.sup.4 group can optionally be the amine group of the N-terminus of the peptide so as to form a cyclic peptide,
- or physiologically acceptable salts thereof.
