1. Mutation of a prenyltransferase results in accumulation of subglutinols and destruxins and enhanced virulence in the insect pathogen, Metarhizium anisopliae
Chengzhou Li, Wenyou Huang, Tingting Zhou, Qian Zhao, Peiquan Huang, Ping Qi, Song Huang, Shuaishuai Huang, Nemat O Keyhani, Zhen Huang Environ Microbiol. 2022 Mar;24(3):1362-1379. doi: 10.1111/1462-2920.15859. Epub 2021 Dec 27.
The insect pathogenic fungus, Metarhizium anisopliae is a commercialized microbial agent used in biological control efforts targeting a diverse range of agricultural and other insect pests. The second step in the synthesis of a group of M. anisopliae α-pyrone diterpenoids (termed subglutinols) involves the activity of a prenyltransferase family geranylgeranyl diphosphate synthase (product of the subD/MaGGPPS5 gene). Here, we show that targeted gene disruption of MaGGPPS5 results in earlier conidial germination and faster greater vegetative growth compared to the wild type (WT) parent and complemented strains. In addition, insect bioassays revealed that the ΔMaGGPPS5 mutant strain displayed significantly increased virulence, with a ~50% decrease in the mean lethal time (LT50 , from 6 to 3 days) to kill (50% of) target insects, and an ~15-40-fold decrease in the mean lethal dose (LC50 ). Metabolite profiling indicated increased accumulation in the ΔMaGGPPS5 mutant of select subglutinols (A, B and C) and destruxins (A, A2, B and B2), the latter a set of fungal secondary metabolites that act as insect toxins, with a concomitant loss of production of subglutinol 'analogue 45'. These data suggest that the increased virulence phenotype seen for the ΔMaGGPPS5 strain can, at least in part, be attributed to a combination of faster growth and increased insect toxin production, linking the production of two different secondary metabolite pathways, and represent a novel approach for the screening of isolates with enhanced virulence via modulation of terpenoid secondary metabolite biosynthesis.
2. Combinatorial Synthesis and Biological Evaluation of Destruxins
Masahito Yoshida Chem Pharm Bull (Tokyo). 2019;67(10):1023-1029. doi: 10.1248/cpb.c19-00272.
The combinatorial synthesis and biological evaluation of destruxins are described herein. First, the total synthesis of destruxin E was achieved, and its absolute configuration was successfully determined to be (S). In addition, the preparation of a combinatorial library based on the structure of destruxins was carried out by the split-and-pool method. Biological evaluation of the resulting analogs against osteoclast-like multinuclear cells (OCLs) revealed that the N-methyl-alanine residue was crucial to inducing morphological changes in OCLs. In particular, functionalization at the β-position of the proline (Pro) residue was found to be tolerant of the desired biological activity of destruxin E, suggesting that the β-position of the Pro residue should be a promising site for the introduction of a chemical tag toward the preparation of a molecular probe.
3. Synthetic studies for destruxins and biological evaluation for osteoclast-like multinucleated cells: a review
Masahito Yoshida, Hiroshi Nakagawa, Takayuki Doi J Antibiot (Tokyo). 2022 Aug;75(8):420-431. doi: 10.1038/s41429-022-00540-8. Epub 2022 Jul 11.
Synthesis of various destruxin analogs was accomplished using Shiina's macrolactonization as a key reaction. Combinatorial synthesis of cyclization precursors using solid-phase peptide synthesis and macrolactonization in solution were successful. In the synthesis of destruxin E and its analogs, the hydroxyacid-proline (HA1-Pro2) dipeptide with an acetonide-protected diol moiety was synthesized in an asymmetric manner, and the protected diol was converted to an epoxide after macrocyclization. Destruxin E was synthesized on a gram scale using solution-phase synthesis. The structure-activity relationships of destruxins were elucidated through biological evaluation of synthetic destruxins A, B, and E and their analogs for morphological changes in osteoclast-like multinucleated cells.
