摘要:
Methods to elevate progenitor and stem cell counts in animal subjects using compounds which bind to the chemokine receptor CXCR4 are disclosed. Preferred embodiments of such compounds are of the formula Z-linker-Z' (1) or pharmaceutically acceptable salt thereofwherein Z is a cyclic polyamine containing 9-32 ring members of which 3-8 are nitrogen atoms, said nitrogen atoms separated from each other by at least 2 carbon atoms, and wherein said heterocycle may optionally contain additional heteroatoms besides nitrogen and/or may be fused to an additional ring system; or Z is of formula (a), wherein A comprises a monocyclic or bicyclic fused ring system containing at least one N and B is H or an organic moiety of 1-20 atoms, Z' may be embodied in a form as defined by Z above, or alternatively may be of the formula -N(R)-(CR 2 ) n -X wherein each R is independently H or straight, branched or cyclic alkyl (1-6C), n is 1 or 2, and X is an aromatic ring, including heteroaromatic rings, or is a mercaptan; "linker" represents a bond, alkylene (1-6C) or may comprise aryl, fused aryl, oxygen atoms contained in an alkylene chain, or may contain keto groups or nitrogen or sulphur atoms.Det beskrives fremgangsmåter for å øke progenitor- og stamcelleantallet i et dyr ved bruk av forbindelser som binder til kjemokinreseptoren CXCR4. Foretrukne utførelsesformer av slike forbindelser har formelen Z-Iinker-Z' (1) eller et farmasøytisk akseptabelt salt derav, hvor Z er et cyklisk polyamin som inneholder 9-32 ringledd, hvorav 3-8 er nitrogenatomer, nevnte nitrogenatomer er adskilt fra hverandre med minst 2 karbonatomer, og hvor nevnte heterocykliske ring eventuelt kan inneholde ytterligere heteroatomer foruten nitrogen og/eller være kondensert til et ytterligere ringsystem; eller Z har formelen (A), hvor A omfatter et monocyklisk eller bicyklisk kondensert ringsystem som inneholder minst én N, og B er H eller en organisk del med 1-20 atomer, Z kan være i en form som definert for Z ovenf
