摘要:
This invention relates to characterisation of the biosynthetic gene cluster for the lantibiotic actagardine, identification of a novel variant of actagardine and its biosynthetic cluster, and methods of production and use of actagardine, a novel actagardine variant, herein referred to as actagardine B, and variants of both of these produced according to this invention, utilizing genes from the characterised biosynthetic gene clusters.
摘要:
The present invention provides actagardine, actagradine B and deoxy actagardine B derivatives of formula (I), wherein: X1 denotes that the residue is Leu; Val; or Ile; X2 denotes that the residue is Leu; Val; or Ile; R1 represents an alkyl or heteroalkyl group, substituted by at least one hydroxyl substituent, and R2 represents hydrogen, or an alkyl or heteroalkyl group, optionally substituted by at least one hydroxyl substituent, or R1 and R2 taken together with the nitrogen atom represent a heterocyclic group having at least one hydroxyl substituent, wherein the heterocyclic group optionally further contains one or more heteroatoms; Z is an amino acid residue, -NR3R4, -NR5COR6, -NR5C(O)OR6; -NR5SOR6, NR5SO2 R6; -NR5C(S)NR6R7, -NR5C(NR8)NR6R7, or -N=R9, where R3, R4, R5, R6, R7, R8 and R9 are independently hydrogen, or a group, optionally substituted, selected from alkyl, heteroalkyl, aryl, heteroaryl, aralkyl and heteroaralkyl, with the proviso that R9 is not hydrogen; and Y is -S- or -S(O)-. The compounds find use in the treatment of microbial infections.

Die Erfindung betrifft Acarbose-Biosynthesegene aus Actinomyceten, vorwiegend aus Actinoplanes sp. SE 50/110 und seiner Mutanten, ein Verfahren zur Isolierung von Acarbose-Biosynthesegenen aus Actinomyceten mittels einer Gensonde, die von hochkonservierten Proteinbereichen bekannter dTDP-Glucose-Dehydratase-Enzyme abgeleitet wurde, für das Auffinden der Gene acbA (kodierend für dTDP-Glucose synthase), acbB (kodierend für dTDP-Glucose dehydratase) und acbC (kodierend für eine Cyclase, z.T. identisch mit AroB, bakteriellen 3-Dehydrochinasäure Synthasen) oder einem oder mehreren Acarbose-Biosynthesegenen aus Actinoplanes sp., sowie die Verwendung der Acarbose-Biosynthesegene.
