Abstract
Micromonospora, one of the most important actinomycetes genera, is well-known as the treasure trove of bioactive secondary metabolites (SMs). Herein, together with an in-depth genomic analysis of the reported Micromonospora strains, all SMs from this genus are comprehensively summarized, containing structural features, bioactive properties, and mode of actions as well as their biosynthetic and chemical synthesis pathways. The perspective enables a detailed view of Micromonospora-derived SMs, which will enrich the chemical diversity of natural products and inspire new drug discovery in the pharmaceutical industry.

Lysoquinone-TH1, a New Polyphenolic Tridecaketide Produced by Expressing the Lysolipin Minimal PKS II in Streptomyces albus. Antibiotics (Basel) 2018; 7:antibiotics7030053. [PMID: 29958422 PMCID: PMC6164072 DOI: 10.3390/antibiotics7030053] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2018] [Revised: 06/12/2018] [Accepted: 06/22/2018] [Indexed: 12/19/2022] Open
Abstract
The structural repertoire of bioactive naphthacene quinones is expanded by engineering Streptomyces albus to express the lysolipin minimal polyketide synthase II (PKS II) genes from Streptomyces tendae Tü 4042 (llpD-F) with the corresponding cyclase genes llpCI-CIII. Fermentation of the recombinant strain revealed the two new polyaromatic tridecaketides lysoquinone-TH1 (7, identified) and TH2 (8, postulated structure) as engineered congeners of the dodecaketide lysolipin (1). The chemical structure of 7, a benzo[a]naphthacene-8,13-dione, was elucidated by NMR and HR-MS and confirmed by feeding experiments with [1,2-13C₂]-labeled acetate. Lysoquinone-TH1 (7) is a pentangular polyphenol and one example of such rare extended polyaromatic systems of the benz[a]napthacene quinone type produced by the expression of a minimal PKS II in combination with cyclases in an artificial system. While the natural product lysolipin (1) has antimicrobial activity in nM-range, lysoquinone-TH1 (7) showed only minor potency as inhibitor of Gram-positive microorganisms. The bioactivity profiling of lysoquinone-TH1 (7) revealed inhibitory activity towards phosphodiesterase 4 (PDE4), an important target for the treatment in human health like asthma or chronic obstructive pulmonary disease (COPD). These results underline the availability of pentangular polyphenolic structural skeletons from biosynthetic engineering in the search of new chemical entities in drug discovery.

Abstract
Three new compounds, designated scopranones A-C, were isolated from the culture broth of a soil isolate, Streptomyces sp. BYK-11038, and shown to be inhibitors of bone morphogenetic protein (BMP) induced alkaline phosphatase activity in a BMP receptor mutant cell line. The structures were elucidated using NMR and other spectral data. The scopranones have an unusual structure with two atypical scooplike moieties linked at the tails to form part of a unique 3-furanone ring.

Abstract
K-259-2 and KS-619-1, novel anionic anthraquinone metabolites isolated from culture broth of microorganisms, inhibited activation of bovine brain phosphodiesterase induced by calmodulin (CaM), sodium oleate, or limited proteolysis with almost equal potency. The inhibition of calmodulin-activated phosphodiesterase (CaM-PDE) by K-259-2 or KS-619-1 was overcome by a higher concentration of CaM. Direct interaction of K-259-2 and KS-619-1 with CaM was confirmed through use of hydrophobic fluorescent probes. Kinetic analysis revealed that the inhibition of the trypsin-activated phosphodiesterase was competitively inhibited by K-259-2 or KS-619-1 with respect to cAMP. Addition of a lower amount of either phosphatidylserine or sodium oleate to the reaction mixture was efficacious in attenuating the inhibition of the CaM-PDE by W-7, chlorpromazine, trifluoperazine, compound 48/80, or R-24571 but, in contrast, had little or no effect on the inhibition by K-259-2 or KS-619-1. In conclusion, K-259-2 and KS-619-1, unlike so-called CaM antagonists, do not interact with phosphatidylserine or sodium oleate and it appears that these novel anthraquinone compounds inhibit the enzyme not only via CaM antagonism but possibly also by interacting directly with the enzyme.
