Unique Self-Anhydride Formation in the Degradation of Cytidine-5′-monophosphosialic Acid (CMP-Neu5Ac) and Cytidine-5′-diphosphosialic Acid (CDP-Neu5Ac) and its Application in CMP-sialic Acid Analogue Synthesis
compounds except for cytidine‐5′‐monophosphosialic acid (CMP‐Neu5Ac). To obtain an insight into why cytidine‐5′‐diphosphosialic acid (CDP‐Neu5Ac) has not been used for the sialyltransferase reaction and why it is not found in biological organisms, the compound was synthesised. This synthesis provided the interesting finding that the carboxylic acid moiety of the sialic acid attacks the attached phosphate

Bone targeted compounds and methods are provided. Compounds can include a Bone Targeting Portion (R
T
), having an affinity for bone; a Bone Active Portion (R
A
) for interacting with and affecting bone; a Linking Portion (R
L
) connecting the Bone Targeting Portion and the Bone Active Portion. The Bone Active Portion is derived from an estrogenic agent. Compounds can also include a Blocking Group (R
P
) that reduces or eliminates the estrogenic activity of the Bone Active Portion.

Trimethoxyphenyl substituted indole ligands have been discovered which demonstrate impressive cytotoxicity as well as a remarkable ability to inhibit tubulin assembly. Such compounds as well as related derivatives are excellent clinical candidates for the treatment of cancer in humans. In addition, certain of these ligands, as pro-drugs, may well prove to be tumor selective vascular targeting chemotherapeutic agents or to have vascular targeting activity resulting in the selective prevention and/or destruction of nonmalignant proliferating vasculature.
