Abstract
Fourteen-membered macrolides are a class of compounds with significant clinical value as antibacterial agents. As part of our ongoing investigation into the metabolites of Streptomyces sp. MST-91080, we report the discovery of resorculins A and B, unprecedented 3,5-dihydroxybenzoic acid (α-resorcylic acid)-containing 14-membered macrolides. We sequenced the genome of MST-91080 and identified the putative resorculin biosynthetic gene cluster (rsn BGC). The rsn BGC is hybrid of type I and type III polyketide synthases. Bioinformatic analysis revealed that the resorculins are relatives of known hybrid polyketides: kendomycin and venemycin. Resorculin A exhibited antibacterial activity against Bacillus subtilis (MIC 19.8 μg mL-1), while resorculin B showed cytotoxic activity against the NS-1 mouse myeloma cell line (IC50 3.6 μg mL-1).

Mar Drugs 2022; 20:691. [PMID: 36355013 PMCID: PMC9697125 DOI: 10.3390/md20110691] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Revised: 10/26/2022] [Accepted: 10/27/2022] [Indexed: 09/01/2023] Open
Abstract
Tuberculosis has become a major health problem globally. This is worsened by the emergence of resistant strains of Mycobacterium tuberculosis showing ability to evade the effectiveness of the current antimycobacterial therapies. Therefore, the efforts carried out to explore new entities from many sources, including marine, are critical. This review summarizes several marine-derived macrolides that show promising activity against M. tuberculosis. We also provide information regarding the biosynthetic processes of marine macrolides, including the challenges that are usually experienced in this process. As most of the studies reporting the antimycobacterial activities of the listed marine macrolides are based on in vitro studies, the future direction should consider expanding the trials to in vivo and clinical trials. In addition, in silico studies should also be explored for a quick screening on marine macrolides with potent activities against mycobacterial infection. To sum up, macrolides derived from marine organisms might become therapeutical options for tackling antimycobacterial resistance of M. tuberculosis.

Yan YS, Xia HY. Recent advances in the research of milbemycin biosynthesis and regulation as well as strategies for strain improvement. Arch Microbiol 2021; 203:5849-5857.

Abstract
Milbemycins, a group of 16-membered macrocylic lactones with excellent acaricidal, insecticidal and anthelmintic activities, can be produced by several Streptomyces species. For the reason that they have low toxicity in mammals, milbemycins and their derivatives are widely used in agricultural, medical and veterinary industries. Streptomyces bingchenggensis, one of milbemycin-producing strains, has been sequenced and intensively investigated in the past decades. In this mini-review, we comprehensively revisit the progress that has been made in research efforts to elucidate the biosynthetic pathways and regulatory networks for the cellular production of milbemycins. The advances in the development of production strains for milbemycin and its derivatives are discussed along the strain-generation technical approaches of random mutagenesis, metabolic engineering and combinatorial biosynthesis. The research progress made so far indicates that strain improvement and generation of novel milbemycin derivatives will greatly benefit from future development of enabling technologies and deeper understanding of the fundamentals of biosynthesis of milbemycin and the regulation of its production in S. bingchenggensis. This mini-review also proposes that the overproduction of milbemycins could be greatly enhanced by genome minimization, systematical metabolic engineering and synthetic biology approaches in the future.

Determination of Lekethromycin, a Novel Macrolide Lactone, in Rat Plasma by UPLC-MS/MS and Its Application to a Pharmacokinetic Study. Molecules 2020; 25:molecules25204676. [PMID: 33066303 PMCID: PMC7587338 DOI: 10.3390/molecules25204676] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2020] [Revised: 10/06/2020] [Accepted: 10/07/2020] [Indexed: 11/16/2022] Open
Abstract
Lekethromycin, a new macrolide lactone, exhibits significant antibacterial activity. In this study, a reliable analytical ultrahigh-performance liquid chromatography electrospray ionization quadrupole Orbitrap high-resolution mass spectrometry (UPLC-ESI-Orbitrap-MS) method was established and validated for the detection of lekethromycin in rat plasma. After a simple acetonitrile (ACN)-mediated plasma protein precipitation, chromatographic separation was performed on a Phenomenex Luna Omega PS C18 column (30 × 2.1 mm i.d. particle size = 3 μm) conducted in a gradient elution procedure using 0.5% formic acid (FA) in ACN and 0.5% FA in water as the mobile phase pumped at a flow rate of 0.3 mL/min. Detection was carried out under positive electrospray ionization (ESI+) conditions in parallel reaction monitoring (PRM) mode with observation of m/z 804.5580 > 577.4056 for lekethromycin and 777.5471 > 619.4522 for gamithromycin (internal standard, IS). The linear range was 5–1000 ng/mL (r2 > 0.99), and the lower limit of quantification (LLOQ) was 5 ng/mL. The intra- and inter-day precision (expressed as relative standard deviation, RSD) values were ≤7.3% and ≤6.3%, respectively, and the accuracy was ≥90% ± 5.3%. The mean extraction recovery RSD valWeue was <5.1%. Matrix effects and dilution integrity RSD values were <5.6% and <3.2%, respectively. Lekethromycin was deemed stable under certain storage conditions. This fully validated method was effectively applied to study the pharmacokinetics of lekethromycin after a single intravenous administration of 5 mg/kg in rats. The main pharmacokinetic parameters were T1/2λz, CL_obs and VZ_obs were 32.33 ± 14.63 h, 0.58 ± 0.17 L/h/kg and 25.56 ± 7.93 L/kg, respectively.

Abstract
Actinobacteria are characterized as the most prominent producer of natural products (NPs) with pharmaceutical importance. The production of NPs from these actinobacteria is associated with particular biosynthetic gene clusters (BGCs) in these microorganisms. The majority of these BGCs include polyketide synthase (PKS) or non-ribosomal peptide synthase (NRPS) or a combination of both PKS and NRPS. Macrolides compounds contain a core macro-lactone ring (aglycone) decorated with diverse functional groups in their chemical structures. The aglycon is generated by megaenzyme polyketide synthases (PKSs) from diverse acyl-CoA as precursor substrates. Further, post-PKS enzymes are responsible for allocating the structural diversity and functional characteristics for their biological activities. Macrolides are biologically important for their uses in therapeutics as antibiotics, anti-tumor agents, immunosuppressants, anti-parasites and many more. Thus, precise genetic/metabolic engineering of actinobacteria along with the application of various chemical/biological approaches have made it plausible for production of macrolides in industrial scale or generation of their novel derivatives with more effective biological properties. In this review, we have discussed versatile approaches for generating a wide range of macrolide structures by engineering the PKS and post-PKS cascades at either enzyme or cellular level in actinobacteria species, either the native or heterologous producer strains.
