Application Number:	08/470,027
Claims:	1. A method of enhancing hematopoiesis in an animal in need of such treatment comprising administering to said animal a hematopoiesis stimulating amount of one or more compounds selected from the group consisting of ##STR19## wherein R.sub.1, R.sub.2, and R.sub.3 are the same or different and each is hydrogen or an acyl group derived from (a) an unbranched fatty acid with 2 to 22 carbon atoms, (b) an amino acid selected from the group consisting of glycine, the L forms of alanine, valine, leucine, isoleucine, tyrosine, proline, hydroxyproline, serine, threonine, cysteine, aspartic acid, glutamic acid, arginine, lysine, histidine, carnitine, and ornithine, (c) nicotinic acid, or (d) a dicarboxylic acid having 3 to 22 carbon atoms, provided that not all of R.sub.1, R.sub.2, and R.sub.3 are H, or a pharmaceutically acceptable salt thereof. 2. A method as in claim 1 wherein said compound is ##STR20## wherein R.sub.1, R.sub.2, and R.sub.3 are the same or different and each is hydrogen or an acyl group derived from (a) an unbranched fatty acid with 2 to 22 carbon atoms, (b) an amino acid selected from the group consisting of glycine, the L forms of alanine, valine, leucine, isoleucine, tyrosine, proline, hydroxyproline, serine, threonine, cysteine, aspartic acid, glutamic acid, arginine, lysine, histidine, carnitine, and ornithine, (c) nicotinic acid, or (d) a dicarboxylic acid having 3 to 22 carbon atoms, provided that not all of R.sub.1, R.sub.2, and R.sub.3 are H, or a pharmaceutically acceptable salt thereof. 3. A method as in claim 1 wherein said compound is ##STR21## wherein R.sub.1, R.sub.2, and R.sub.3 are the same or different and each is hydrogen or an acyl group derived from (a) an unbranched fatty acid with 2 to 22 carbon atoms, (b) an amino acid selected from the group consisting of glycine, the L forms of alanine, valine, leucine, isoleucine, tyrosine, proline, hydroxyproline, serine, threonine, cysteine, aspartic acid, glutamic acid, arginine, lysine, histidine, camitine, and ornithine, (c) nicotinic acid, or (d) a dicarboxylic acid having 3 to 22 carbon atoms, provided that not all of R.sub.1, R.sub.2, and R.sub.3 are H, or a pharmaceutically acceptable salt thereof. 4. A method as in claim 1 wherein said compound is ##STR22## wherein R.sub.1, R.sub.2, and R.sub.3 are the same or different and each is hydrogen or an acyl group derived from (a) an unbranched fatty acid with 2 to 22 carbon atoms, (b) an amino acid selected from the group consisting of glycine, the L forms of alanine, valine, leucine, isoleucine, tyrosine, proline, hydroxyprolne, serine, threonine, cysteine, aspartic acid, glutamic acid, arginine, lysine, histidine, carnitine, and ornithine, (c) nicotinic acid, or (d) a dicarboxylic acid having 3 to 22 carbon atoms, provided that not all of R.sub.1, R.sub.2, and R.sub.3 are H, or a pharmaceutically acceptable salt thereof. 5. A method as in claim 1 wherein said compound is ##STR23## wherein R.sub.1, R.sub.2, and R.sub.3 are the same or different and each is hydrogen or an acyl group derived from (a) an unbranched fatty acid with 2 to 22 carbon atoms, (b) an amino acid selected from the group consisting of glycine, the L forms of alanine, valine, leucine, isoleucine, tyrosine, proline, hydroxyproline, serine, threonine, cysteine, aspartic acid, glutamic acid, arginine, lysine, histidine, carnitine, and ornithine, (c) nicotinic acid, or (d) a dicarboxylic acid having 3 to 22 carbon atoms, provided that not all of R.sub.1, R.sub.2, and R.sub.3 are H, or a pharmaceutically acceptable salt thereof. 6. A method as in claim 2 wherein R.sub.1, R.sub.2 and R.sub.3 are the same or different and each is an unbranched fatty acid with 3-22 carbon atoms. 7. A method as in claim 3 wherein R.sub.1, R.sub.2 and R.sub.3 are the same or different and each is an unbranched fatty acid with 3-22 carbon atoms. 8. A method as in claim 4 wherein R.sub.1, R.sub.2 and R.sub.3 are the same or different and each is an unbranched fatty acid with 3-22 carbon atoms. 9. A method as in claim 5 wherein R.sub.1, R.sub.2 and R.sub.3 are the same or different and each is an unbranched fatty acid with 3-22 carbon atoms.
