    摘要: 3,5-Dihydroxypentanoic ester derivatives of formula (I): ##STR1## wherein: A represents an alkylene group which is optionally substituted by one or more alkyl groups, or an alkenylene group;Z represents a substituted or unsubstituted aryl or aryloxy group; andR represents a C.sub.1 -C.sub.4 alkyl group) may be prepared by reacting a dianion of an acetoacetic ester with an aldehyde of formula Z-A-CHO (wherein A and Z are as defined above) and then reducing the resulting compound. These 3,5-dihydroxypentanoic ester derivatives have antihyperlipaemic activity and are thus valuable pharmaceuticals.

    摘要: A compound of formula (I): ##STR1## (called 6-methoxy-IsoML-236B lactone) and its corresponding free hydroxy-carboxylic acid and salts and esters of said acid may be prepared by the enzymatic alkoxylation of an ML-236B compound, preferably using a microorganism of the genus Syncephalastrum, Absidia or Cunninghamella, e.g. Absidia coerulea, or a cell-free enzyme-containing extract from said microorganism. If desired, the lactone or carboxylic acid may be converted by conventional salification or esterification techniques to the desired salt or ester. These compounds have the ability to inhibit the biosynthesis of cholesterol and are thus of value in the treatment of hypercholesteraemia, for which purpose they may be formulated as compositions in admixture with conventional pharmaceutical carriers or diluents.

    摘要: Compounds of formula (I): ##STR1## wherein R.sup.1 represents a group of formula ##STR2## or a group of formula ##STR3## (wherein R.sup.2 represents a C.sub.1 --C.sub.10 alkyl group) and their corresponding free hydroxy-carboxylic acids and salts and esters of said acids may be prepared by the enzymatic hydroxylation of an MB-530B compound (which may be the lactone, the carboxylic acid or a salt or ester of MB-530B or a corresponding compound in which the 2-methylbutyryloxy group at the 1-position of these compounds has been replaced by another C.sub.2 --C.sub.11 acyloxy group), preferably using a microorganism of the genus Syncephalastrum, Mucor, Rhizopus, Zygorinchus, Circinella, Actinomucor, Gongronella, Phycomyces, Streptomyces, Absidia, Cunninghamella, Mortierella, Pycnoporus or Rhizoctonia, or a cell-free enzyme-containing extract from the microorganism. If desired, the lactone or carboxylic acid may be converted by conventional salification or esterification techniques to the desired salt or ester and the salt or ester may be converted to the parent lactone or acid. These compounds have the ability to inhibit the biosynthesis of cholesterol and are thus of value in the treatment of hypercholesteraemia, for which purpose they may be formulated as compositions in admixture with conventional pharmaceutical carriers or diluents.

    摘要: Dihydro-M-4 and dihydro-IsoM-4 are new compounds which may be prepared by the catalytic hydrogenation of M-4 or IsoM-4 respectively. They, and their salts and esters (which may be prepared by conventional salification or esterification reactions with the parent dihydro-M-4 or dihydro-IsoM-4), are capable of inhibiting cholesterol biosynthesis in the liver and may be formulated, for therapeutic use, with conventional pharmaceutical carriers or diluents.
