摘要:
The invention relates to analogs of 4-hydroxyisoleucine, and to lactones, pharmaceutically acceptable salts, and prodrugs thereof, to processes for their preparation, and to pharmaceutical compositions comprising the same. The analogs of the invention stimulate both glucose uptake and insulin secretion, and might thus be useful for the prevention and treatment of disorders of carbohydrate or lipid metabolism, including diabetes mellitus (type 1 and type 2 diabetes), pre-diabetes, and Metabolic Syndrome.
摘要:
Novel sphingosine analogues useful as intermediates for the synthesis of novel lipid derivatives such as sphingolipid derivatives controlling the function of sphingolipid. The sphingosine analogues are represented by general formula (I), wherein Q?1 and Q2¿ are each independently hydrogen, C¿1?-C4 alkyl, C2-C5 acyl or an amino-protecting group and Q?3¿ is hydrogen or a hydroxyl-protecting group, or alternatively Q?2 and Q3¿ are united to form isopropylidene and Q1 is hydrogen or an amino-protecting group; Q?4 and Q5¿ are each independently hydroxyl, C¿2?-C5 acyl, -O-Q?6¿ or hydrogen, or alternatively Q?4 and Q5¿ may be united to form a covalent bond; Q6 is a hydroxyl-protecting group; X1 is -COOH, -CONH¿2?, -CO-Q?7, -CH¿2OH or -CH2O-Q8; Q7 is a carboxyl-protecting group; and Q8 is a hydroxyl-protecting group.
摘要:
This invention relates to a new class of polyene polyketides, their pharmaceutically acceptable salts and derivatives, and to methods for obtaining the compounds. One method of obtaining these compounds is by cultivation of novel strains of Streptomyces aizunensis; another method involves expression of biosynthetic pathway genes in transformed host cells. The present invention further relates to the novel strains of Streptomyces aizunensis used to produce these compounds, to the use of these compounds and their pharmaceutically acceptable salts and derivatives as pharmaceuticals, in particular to their use as inhibitors of fungal cell growth and cancer cell growth. The invention also relates to pharmaceutical compositions comprising these novel polyketides or a pharmaceutically acceptable salts or derivatives thereof. Finally, the invention relates to novel polynucleotide sequences and their encoded proteins, which are involved in the biosynthesis of these novel polyketides.
