Title:	Oxpurine nucleosides and their congeners, and acyl, derivatives thereof, for improvement of hematopoiesis
Abstract:	The invention relates to certain oxypurine nucleosides, congeners of such oxypurine nucleosides, and acyl derivatives thereof, and compositions which contain at least one of these compounds. The invention also relates to methods of treating or preventing hematopoietic disorders and modifying hematopoiesis, and treating or preventing inflammatory diseases and bacterial infections by administering a compound or composition of the present invention to an animal.
