The present invention provides an agent for improving the blood stability of an endogenous ligand, which comprises an antibody that has affinity to the mammalian endogenous ligand but substantially does not neutralize the same, and the above-described agent for the prophylaxis and/or treatment for a disease for which an increase in the blood concentration of the endogenous ligand and/or an prolonged blood half-life is prophylactically or therapeutically effective. Provided that the above-described agent is administered alone to a mammal without co-administering the same or substantially the same compound as the endogenous ligand, the blood stability of the endogenous ligand increases and the receptor activity-regulatory action thereof is enhanced.
Sialic acid derivatives represented by the following general formula:
wherein R1 represents a residue of a steroid compound excluding cholestane and cholestene residues, R2 represents hydrogen or methyl group, R3 represents a C1-C6 alkyl group and other, R4 represents hydrogen or acyl group, R5 represents a group of R15O— (R15 represents a C2-C7 acyl group and other), and X represents oxygen or sulfur atom, and their derivatives. These derivatives have activating effect on choline acetyltransferase activity in the chlonergic neurons, and are useful for preventive and therapeutic treatment of dementia, memory disorder, peripheral nervous disorder and so forth.
A compound of the formula: ##STR1## wherein ##STR2## represents a cyclic amino group, A represents a methylene group or a carbonyl group, m represents an integer of 1 to 3, n represents an integer of 0 to 4 and p represents an integer of 1 to 2, or a salt thereof, which has glutamate receptor inhibiting activity is provided.
