The present invention relates to a cycloalkene derivative represented by the formula (I):
wherein each symbol is as defined in the specification, a pharmaceutical agent containing the derivative, and a production method thereof. The cycloalkene derivative of the present invention has high solubility in water and is suitable for use as an injection.
22-Oxacalcitriol 3-hemiglutarate, a haptenic derivative of 22-oxacalcitriol, was synthesized to obtain a specific antibody for use in radioimmunoassay. Three antisera were elicited in rabbits against the hapten conjugated with bovine serum albumin, and their specificity was examined by cross-reaction study. One of the antisera was found to be satisfactorily specific, and expected to provide a radioimmunoassay useful for the pharmacokinetic study of 22-oxacalcitriol.
