실험 절차

Hollow magnetic microcapsules 41 were obtained under the same conditions as in Example 108 except that the purified enzyme solution (1) used in Example 108 was replaced by the crude enzyme solution (3) and (R)-3-hydroxybutyryl CoA was replaced by (R,S)-3-hydroxy-5-phenoxyvaleryl CoA (prepared by hydrolyzing 3-hydroxy-5-phenoxy valerate obtained through a Reformatsky reaction with zinc using 3-phenoxypropanal and ethyl bromoacetate as raw materials, which were synthesized according to a procedure described in J. Org. Chem., 55, 1490-1492, 1990, to produce 3-hydroxy-5-phenoxy valeric acid and then following a procedure described in Eur. J. Biochem., 250, 432-439, 1997). An ultrasonic contrast agent employing the hollow magnetic microcapsules 41 is referred to as an ultrasonic contrast agent 41.
