Front Microbiol 2023; 14:1274358.

Abstract
The pluramycin family of natural products has diverse substituents at the C2 position, which are closely related to their biological activity. Therefore, it is important to understand the biosynthesis of C2 substituents. In this study, we describe the biosynthesis of C2 moieties in Streptomyces sp. W2061, which produces kidamycin and rubiflavinone C-1, containing anthrapyran aglycones. Sequence analysis of the loading module (Kid13) of the PKS responsible for the synthesis of these anthrapyran aglycones is useful for confirming the incorporation of atypical primer units into the corresponding products. Kid13 is a ketosynthase-like decarboxylase (KSQ)-type loading module with unusual dual acyltransferase (AT) domains (AT1-1 and AT1-2). The AT1-2 domain primarily loads ethylmalonyl-CoA and malonyl-CoA for rubiflavinone and kidamycinone and rubiflavinone, respectively; however, the AT1-1 domain contributed to the functioning of the AT1-2 domain to efficiently load ethylmalonyl-CoA for rubiflavinone. We found that the dual AT system was involved in the production of kidamycinone, an aglycone of kidamycin, and rubiflavinone C-1 by other shared biosynthetic genes in Streptomyces sp. W2061. This study broadens our understanding of the incorporation of atypical primer units into polyketide products.

Abstract
The pluramycin family of antibiotics comprises angucycline compounds derived from actinomycetes that possess anticancer and antibacterial properties. Pluramycins are structurally characterized by two aminoglycosides linked by a carbon-carbon bond next to the γ-pyrone angucycline backbone. Kidamycins (3, 4) and rubiflavins (6-9) were screened through liquid chromatography-mass spectrometry analysis of the crude extracts of Streptomyces sp. W2061, which was cultured in complex media under phosphate-limiting conditions. Newly isolated rubiflavin G (7) and photoactivated compounds (8, 9) were characterized using exhaustive 1D and 2D nuclear magnetic resonance analysis. The cytotoxicity of kidamycin (3), photokidamycin (4), and photorubiflavin G (8) was determined using two human breast cancer cell lines-MCF7 and MDA-MB-231. Compared to MCF7 cells, MDA-MB-231 cells were more sensitive to the active compounds, and photokidamycin (4) considerably inhibited MCF7 and MDA-MB-231 cell growth (IC50 = 3.51 and 0.66 μM, respectively).

Abstract
In this paper, a new access to several chiral 3-aminoglycals as potential precursors for glycosylated natural products is reported from a common starting material, (-)-methyl-L-lactate. The stereodivergent strategy is based on the implementation of a ring-closing metathesis of vinyl ethers as key step of reaction sequences developed.
