A wave power generation device for synchronizing a vertical movement of a float with all the wave periods, and a method of controlling the same. The device has a controller which controls a torque of a power generator, and the controller is configured to estimate a displacement and a speed of a float from data of a rotation number or a rotation speed of the power generator, to estimate a wave period from the displacement and the speed, and to determine a displacement coefficient corresponding to the wave period from a data table stored in advance, and to transmit a calculated product of the displacement coefficient and the displacement as a torque command to the power generator so as to control a torque of the power generator.

Derivatives of ML-236B carboxylic acid, its salts and esters and corresponding lactone have a hydroxy group at the 3'-position and optionally also at the 6'-position. These derivatives may be prepared by the enzymatic hydroxylation of a corresponding ML-236B compound employing an enzyme produced by a microorganism of the genus Streptomyces or Amycolata, especially Streptomyces sp. SANK 62285, Streptomyces sp. SANK 62385, Streptomyces sp. SANK 62485, Streptomyces sp. SANK 62585, Amycolata autotrophica SANK 62781. Amycolata autotrophica subsp. canberrica SANK 62882 or Amycolata autotrophica subsp. amethystina SANK 62981. These derivatives have the ability to inhibit cholesterol biosynthesis.
