Isolation and structure determination of allopteridic acids A-C and allokutzmicin from an unexplored actinomycete of the genus Allokutzneria. J Antibiot (Tokyo) 2023; 76:305-315. [PMID: 37059821 DOI: 10.1038/s41429-023-00611-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2023] [Revised: 03/05/2023] [Accepted: 03/08/2023] [Indexed: 04/16/2023]
Abstract
Two classes of new polyketides, allopteridic acids A-C (1-3) and allokutzmicin (4), were isolated from the culture extract of an actinomycete of the genus Allokutzneria. The structures of 1-4 were elucidated through the interpretation of NMR and MS analytical data. Compounds 1-3 possess the same carbon skeleton with pteridic acids but their monocyclic core structures are distinct from the spiro-bicyclic acetal structures of pteridic acids. Compound 4 is a linear polyketide of an unprecedented class, featured by a guanidino-terminus and an epoxide modification. Compounds 1-3 promoted the root elongation of germinated lettuce seeds by ca. 10-40% at 1~10 μM whereas 4 retarded the seed growth. Compound 4 exhibited weak antimicrobial activity against Candida albicans with MIC 25 μg mL-1.

Abstract
Lemonose is a component of the antibiotic lemonomycin and other antibiotics and natural products. Three routes to the synthesis of the title compound, a protected, desmethyl derivative of lemonose, from l-rhamnose or its glycal, were investigated based on electrophilic cyclization, epoxidation-ring opening, and deoxygenation of an intermediate that was used in the synthesis of the amino sugar callipeltose. The deoxygenation route was successful and it provided the title compound, which was then converted to a phenyl thioglycoside.
