Exploring natural microbial resources for the discovery of anti-malarial compounds. Parasitol Int 2021; 85:102432. [PMID: 34363974 DOI: 10.1016/j.parint.2021.102432] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Revised: 06/23/2021] [Accepted: 08/01/2021] [Indexed: 01/21/2023]
Abstract
Microorganisms in nature are highly diverse biological resources, which can be explored for drug discovery. Some countries including Brazil, Columbia, Indonesia, China, and Mexico, which are blessed with geographical uniqueness with diverse climates and display remarkable megabiodiversity, potentially provide microorganismal resources for such exploitation. In this review, as an example of drug discovery campaigns against tropical parasitic diseases utilizing microorganisms from such a megabiodiversity country, we summarize our past and on-going activities toward discovery of new antimalarials. The program was held in a bilateral collaboration between multiple Indonesian and Japanese research groups. In order to develop a new platform of drug discovery utilizing Indonesian bioresources under an international collaborative scheme, we aimed at: 1) establishment of an Indonesian microbial depository, 2) development of robust enzyme-based and cell-based screening systems, and 3) technology transfer necessary for screening, purification, and identification of antimalarial compounds from microbial culture broths. We collected, characterized, and deposited Indonesian microbes. We morphologically and genetically characterized fungi and actinomycetes strains isolated from 5 different locations representing 3 Indonesian geographical areas, and validated genetic diversity of microbes. Enzyme-based screening was developed against two validated mitochondrial enzymes from Plasmodium falciparum, dihydroorotate dehydrogenase and malate:quinone oxidoreductase, while cell-based proliferation assay was developed using the erythrocytic stage parasite of 3D7 strain. More than 17 thousands microbial culture extracts were subjected to the enzyme- and cell-based screening. Representative anti-malarial compounds discovered in this campaign are discussed, including a few isolated compounds that have been identified for the first time as anti-malarial compounds. Our antimalarial discovery campaign validated the Indonesian microbial library as a powerful resource for drug discovery. We also discuss critical needs for selection criteria for hits at each stage of screening and hit deconvolution such as preliminary extraction test for the initial profiling of the active compounds and dereplication techniques to minimize repetitive discovery of known compounds.

Abstract
Covering: up to the second quarter of 2020 Threat or treat? While pathogenic bacteria pose significant threats, they also represent a huge reservoir of potential pharmaceuticals to treat various diseases. The alarming antimicrobial resistance crisis and the dwindling clinical pipeline urgently call for the discovery and development of new antibiotics. Pathogenic bacteria have an enormous potential for natural products drug discovery, yet they remained untapped and understudied. Herein, we review the specialised metabolites isolated from entomopathogenic, phytopathogenic, and human pathogenic bacteria with antibacterial and antifungal activities, highlighting those currently in pre-clinical trials or with potential for drug development. Selected unusual biosynthetic pathways, the key roles they play (where known) in various ecological niches are described. We also provide an overview of the mode of action (molecular target), activity, and minimum inhibitory concentration (MIC) towards bacteria and fungi. The exploitation of pathogenic bacteria as a rich source of antimicrobials, combined with the recent advances in genomics and natural products research methodology, could pave the way for a new golden age of antibiotic discovery. This review should serve as a compendium to communities of medicinal chemists, organic chemists, natural product chemists, biochemists, clinical researchers, and many others interested in the subject.

Sci Rep 2020; 10:5081. [PMID: 32193473 PMCID: PMC7081223 DOI: 10.1038/s41598-020-61681-0] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2019] [Accepted: 03/02/2020] [Indexed: 12/18/2022] Open
Abstract
In the process of investigating the antifungal structure-activity relationships (SAR) of borrelidin and discovering antifungal leads, a semisynthetic borrelidin analogue, BN-3b with antifungal activity against Candida albicans, was achieved. In this study, we found that oxidative damage induced by endogenous reactive oxygen species (ROS) plays an important role in the antifungal activity of BN-3b. Further investigation indicated that BN-3b stimulated ROS accumulation, increased malondialdehyde (MDA) levels, and decreased reduced/oxidized glutathione (GSH/GSSG) ratio. Moreover, BN-3b decreased mitochondrial membrane potential (MMP) and ATP generation. Ultrastructure analysis revealed that BN-3b severely damaged the cell membrane of C. albicans. Quantitative PCR (RT-qPCR) analysis revealed that virulence factors of C. albicans SAPs, PLB1, PLB2, HWP1, ALSs, and LIPs were all down-regulated after BN-3b exposure. We also found that BN-3b markedly inhibited the hyphal formation of C. albicans. In addition, in vivo studies revealed that BN-3b significantly prolonged survival and decreased fungal burden in mouse model of disseminated candidiasis.

Abstract
Borrelidins M-O (1-3), along with four previously known family members (4-7), were isolated from marine pulmonated mollusks Onchidium sp. associated Streptomyces olivaceus SCSIO LO13. The structures of 1-3 were elucidated by extensive spectral analyses of HR-ESI-MS, 1D and 2D NMR data. In addition, the cytotoxic and antibacterial activities of 1-7 were evaluated enabling us to propose some tentative structure-activity relationships (SARs), especially those involving modifications at C(22) and the moieties at C(7) and C(8) of the borrelidin scaffold.

Appl Microbiol Biotechnol 2018; 102:7865-7875. [PMID: 30039331 DOI: 10.1007/s00253-018-9237-5] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2018] [Revised: 06/29/2018] [Accepted: 07/10/2018] [Indexed: 01/22/2023]
Abstract
BC194, a derivative of borrelidin (BN) that features a lower cytotoxicity than that of BN due to an altered starter unit, trans-1,2-cyclobutanedicarboxylic acid (trans-1,2-CBDA), is a potent inhibitor of angiogenesis. However, BC194 production has only been reported to occur via mutasynthesis, which requires tedious, multistep genetic manipulation. In this study, we surveyed several factors contributing to the precursor-directed biosynthesis of BC194 and provided an alternative method for the production of BC194 that is directly applicable to other BN-producing strains. First, the precursor-directed biosynthesis of BC194 by a BN-producing strain, Streptomyces rochei MB037 derived from sponge Dysidea arenaria, was carried out in modified Radix astragali (RA) medium with 5 mM trans-1,2-CBDA. Next, possible inhibitors of BN starter unit trans-1,2-cyclopentanedicarboxylic acid (trans-1,2-CPDA) biosynthesis were investigated. It was found that potassium ferricyanide was a possible inhibitor of 3,4-dihydroxyphenylacetate 2,3-dioxygenase (DHPAO) and capable of suppressing the yield of BN and increasing the BC194 yield by 112.5% (from 5.2 ± 0.76 to 11.9 ± 0.59 mg/L). BC194 yield was further enhanced in the presence of 50 mM trans-1,2-CBDA, reaching 20.2 ± 0.62 mg/L. Furthermore, 3% macroporous adsorbent DA-201 resin was added to the fermentation broth, enabling a further 36.6% increase in BC194 production and reaching 27.59 ± 1.15 mg/L. Moreover, an efficient separation of BC194 with approximately 95% purity was developed by employing high-speed counter-current chromatography (HSCCC), achieving an improved recovery (approximately 93%).
