Bourgeois A, Lemos JAS, Roucheray S, Sergerie A, Richard D. The Paradigm Shift of Using Natural Molecules Extracted from Northern Canada to Combat Malaria. Infect Dis Rep 2024; 16:543-560. [PMID: 39051241 PMCID: PMC11270350 DOI: 10.3390/idr16040041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/12/2024] [Revised: 06/12/2024] [Accepted: 06/13/2024] [Indexed: 07/27/2024] Open
Abstract
Parasitic diseases, such as malaria, are an immense burden to many low- and middle-income countries. In 2022, 249 million cases and 608,000 deaths were reported by the World Health Organization for malaria alone. Climate change, conflict, humanitarian crises, resource constraints and diverse biological challenges threaten progress in the elimination of malaria. Undeniably, the lack of a commercialized vaccine and the spread of drug-resistant parasites beg the need for novel approaches to treat this infectious disease. Most approaches for the development of antimalarials to date take inspiration from tropical or sub-tropical environments; however, it is necessary to expand our search. In this review, we highlight the origin of antimalarial treatments and propose new insights in the search for developing novel antiparasitic treatments. Plants and microorganisms living in harsh and cold environments, such as those found in the largely unexploited Northern Canadian boreal forest, often demonstrate interesting properties that are not found in other environments. Most prominently, the essential oil of Rhododendron tomentosum spp. Subarcticum from Nunavik and mortiamides isolated from Mortierella species found in Nunavut have shown promising activity against Plasmodium falciparum.

Abstract
In this study, two linear and corresponding cyclic heptapeptide versions of mortiamide A-lugdunin hybrids were designed and synthesized by integrating an anti-malarial peptide epitope derived from Mortiamide A, combined with four residues known for their membrane interactions. Using this synthetic strategy, the sequence of mortiamide A was partly re-engineered with an epitope sequence of lugdunin along with an amino acid replacement using all-L and D/L configurations. Importantly, the re-engineered cyclic mortiamides with all-L (3) and D/L (4) configurations exhibited promising anti-malarial activities against the P. falciparum drug-sensitive TM4/8 strain with half-maximal inhibitory concentration (IC50) values of 6.2 ± 0.5 and 4.8 ± 0.1 μM, respectively. Additionally, they exhibited anti-malarial activities against the P. falciparum multidrug-resistant V1/S strain with IC50 values of 5.0 ± 2.6 and 3.7 ± 0.7 μM, respectively. Interestingly, a linear re-engineered mortiamide with D/L configuration (2) exhibited promising anti-malarial activities, surpassing those of the re-engineered cyclic mortiamides (3 and 4), against both the P. falciparum sensitive TM4/8 and multidrug-resistant V1/S strains with IC50 values of 3.6 ± 0.5 and 2.8 ± 0.7 μM (IC50 of Mortiamide A = 7.85 ± 0.97, 5.31 ± 0.24 μM against 3D7 and Dd2 strains) without any cytotoxicity at >100 µM. The presence of D/L forms in a linear structure significantly impacted the anti-malarial activity against both the P. falciparum sensitive TM4/8 strain and the multidrug-resistant V1/S strain.

Abstract
Protozoal infections cause significant morbidity and mortality in humans and animals. The use of several antiprotozoal drugs is associated with serious adverse effects and resistance development, and drugs that are more effective are urgently needed. Microorganisms, mammalian cells and fluids, insects, and reptiles are sources of antimicrobial peptides (AMPs) that act against pathogenic microorganisms; these AMPs have been widely studied as a promising alternative therapeutic option to conventional antibiotics, aiming to treat infections caused by multidrug-resistant pathogens. One advantage of AMP molecules is their adaptability, as they can be easily fine-tuned for broad-spectrum or targeted activity by changing the amino acid residues in their sequence. Consequently, these variations in structural and physicochemical properties can alter the antimicrobial activities of AMPs and decrease resistance development. This article presents an overview of peptide activities against amebiasis, giardiasis, trichomoniasis, Chagas disease, leishmaniasis, malaria, and toxoplasmosis. AMPs and their analogs demonstrate great potential as therapeutics, with potent and selective activity, when compared with commercially available drugs, and hold the potential to act as new scaffolds for the development of novel anti-protozoal drugs.

Abstract
BACKGROUND Fungi are prolific producers of bioactive small molecules of pharmaceutical or agricultural interest. The secondary metabolism of higher fungi (Dikarya) has been well-investigated which led to > 39,000 described compounds. However, natural product researchers scarcely drew attention to early-diverging fungi (Mucoro- and Zoopagomycota) as they are considered to rarely produce secondary metabolites. Indeed, only 15 compounds have as yet been isolated from the entire phylum of the Zoopagomycota. RESULTS Here, we showcase eight species of the order Kickxellales (phylum Zoopagomycota) as potent producers of the indole-3-acetic acid (IAA)-derived compounds lindolins A and B. The compounds are produced both under laboratory conditions and in the natural soil habitat suggesting a specialized ecological function. Indeed, lindolin A is a selective agent against plant-pathogenic oomycetes such as Phytophthora sp. Lindolin biosynthesis was reconstituted in vitro and relies on the activity of two enzymes of dissimilar evolutionary origin: Whilst the IAA-CoA ligase LinA has evolved from fungal 4-coumaryl-CoA synthetases, the subsequently acting IAA-CoA:anthranilate N-indole-3-acetyltransferase LinB is a unique enzyme across all kingdoms of life. CONCLUSIONS This is the first report on bioactive secondary metabolites in the subphylum Kickxellomycotina and the first evidence for a non-clustered, two-step biosynthetic route of secondary metabolites in early-diverging fungi. Thus, the generally accepted "gene cluster hypothesis" for natural products needs to be reconsidered for early diverging fungi.

Abstract
Macrocyclic peptidomimetics have been seriously contributing to our arsenal of drugs to combat diseases. The search for nature's discoveries led us to mortiamides A-D (found in a novel fungus from Northern Canada), which is a family of cyclic peptides that clearly have demonstrated impressive pharmaceutical potential. This prompted us to learn more about their solution-state properties as these are central for binding to target molecules. Here, we secured and isolated mortiamide D, and then acquired high-resolution nuclear magnetic resonance (NMR) data to learn more about its structure and dynamics attributes. Sets of two-dimensional NMR experiments provided atomic-level (through-bond and through-space) data to confirm the primary structure, and NMR-driven molecular dynamics (MD) simulations suggested that more than one predominant three-dimensional (3D) structure exist in solution. Further steps of MD simulations are consistent with the finding that the backbones of mortiamides A-C also have at least two prominent macrocyclic shapes, but the side-chain structures and dynamics differed significantly. Knowledge of these solution properties can be exploited for drug design and discovery.

Abstract
Malaria remains one of the major health problems in the world. In this work, a series of squaramide tethered chloroquine, clindamycin, and mortiamide D hybrids have been synthesized to assess their in vitro antiplasmodial activity against 3D7 (chloroquine-sensitive) and Dd2 strains of Plasmodium falciparum. The most active compound, a simple chloroquine analogue, displayed low nanomolar IC50 value against both strains (3 nM for 3D7 strain and 18 nM for Dd2 strain). Moreover, all molecular hybrids incorporating the hydroxychloroquine scaffold showed the most potent activities, exemplified with a chloroquine dimer, IC50 = 31 nM and 81 nM against 3D7 and Dd2 strains, respectively. These results highlight the first time use of clindamycin and mortiamide D as antimalarial molecular hybrids and establish these valuable hits for future optimization.

Abstract
Dominicin, a macrocyclic peptide isolated from the marine sponge Eurypon laughlini, has been synthesized for the first time by solid-phase peptide synthesis. The strategy uses oxime resin and takes advantage of the nucleophile susceptibility of the oxime ester bond. The synthesis relies on the preparation of a linear precursor followed by on-resin head-to-tail concomitant cyclization-cleavage. This is the first report of the use of a Boc/OtBu biorthogonal protection strategy on oxime resin to facilitate concomitant N-terminal and side-chain tert-butyl ether deprotection cyclization of unprotected peptides. Also, we report the first antimalarial investigation of dominicin. Interestingly, the natural macrocyclic peptide demonstrates effective low micromolar activity (1.8 μM) against the chloroquine-mefloquine-pyrimethamine-resistant Dd2 strain of Plasmodium falciparum.
