Abstract: The invention concerns derivatives of drosocin which have an increased half-life in mammalian serum by substituting one or more of the amino acid residues of wild type drosocin with another amino acid or a peptidomimetic moiety capable of replacing said amino acid. These derivatives can be used for antibiotic therapy or in a bacteriocidal composition.

Abstract: This invention relates to a method for the production of a sphingoid base according to formula comprising the steps of (1) dissolving a starting compound according to formula III or a salt thereof in a substantially inert solvent, (2) protecting the NH2 group with a NH2 protecting group, (3) activating the C-4 HR3 group for an elimination reaction with the C-5 HR4 group, (4) causing an elimination reaction to take place to form a double bond between the C-4 and C-5 carbon atom, and (5) removing the NH2 protecting group.

Abstract: The invention pertains to new tripeptide and tetrapeptide analogs suitable as an inhibitor of a prenylpyrophosphate-consuming enzyme complying with formula A-B-B′-D, in which formula:

Abstract: Novel peptide-like FPP-analogues suitable for inhibiting protein:prenyl transferases, such as protein:geranylgeranyl transferase-1, and other prenyl pyrophosphate-consuming enzymes such as squalene synthase and geranylgeranyl pyrophosphate synthase are disclosed.

Abstract: This invention relates to a method for the production of a sphingoid base according to formula 1

Abstract: The invention pertains to novel peptide analogs suitable for inhibiting protein:prenyl transferases. As such they are therapeutically useful in e.g. inhibiting oncogenesis and other unwanted cell proliferation, and in supressing aberrant high signal transduction. The analogs comply with the following formula: in which: R1 is hydrogen or a thiol-protecting group; R2 and R3 are independently hydrogen or C1-C4 alkyl; R4 is hydrogen, C1-C4 alkyl, C1-C4 acyl or peptidyl; R5 is hydrogen or C1-C4 alkyl; R6 is hydrogen or optionally substituted C1-C6 alkyl; A is a direct bond or an optionally substituted C1-C4 alkylene chain; Y represents an oxo group or two hydrogen atoms; Z is oxygen, sulphur, imino or C1-C5 alkyl-, aryl- or acylimino; M is 0, 1 or 2; N is 0 or 1.

Abstract: Triantennary cluster glycoside, wherein each glycoside residue is attached to the branching point of the cluster by a spacer of a long, flexible, hydrophilic chain comprising at least 4 atoms in the chain. The glyciside spacer preferably comprises at least two hydrophilic groups. Use of the triantennary cluster glycoside in pharmaceutical preparations, for instance hypolipidemic medicines.

Abstract: The invention provides a method for inhibiting protein isoprenylation by administration of a polyisoprenyl pyrophosphate analogue.
