Abstract
Undoubtedly, malaria is a vector-borne infectious disease that is increasingly being given attention by many researchers in their efforts to find the best drugs for its treatment. Four groups of mice (6-8 weeks old, 20-25 gram body weight (g bw) were inoculated with Plasmodium berghei NK65 intraperitoneally (i.p.) at 1.0 × 106 infected red blood cells (RBC) before being orally treated for the prophylactic and curative treatment regime with 0.2 mL of 100 mg/kg bw freeze-dried T. cucumerina aqueous extract. Parasitemia levels and inhibition rates were microscopically measured using Giemsa stained blood smear method. Trichosanthes cucumerina possessed strong antimalarial activities against P. berghei NK65 infection in mice. A significant correlation was successfully recorded between the survival time of the seven-day prophylactic treatment group (P7) with its ability to inhibit parasite growth as compared to the curative treatment groups. However, these values are still incomparable to the control group treated with the commercial drugs primaquine and chloroquine. In addition, blood biochemical toxicity analysis of ALT, AST, ALP, and STP showed that acute and sub-acute toxicity treatments of T. cucumerina did not cause liver injury and were non-toxic to the animals. Thus, this study significantly proves (p≤0.05, n=6) that T. cucumerina has antiparasitic properties that can be manipulated as an alternative antimalarial drug.

Abstract
Millions of symbiotic and pathogenic microorganisms known as microbiota colonize the host body. The microbiome plays an important role in human health and colonizes hundreds of different species of multicellular organisms so that they are introduced as the metaorganisms. Changes in the microbial population of the gut microbiome may cause resistance to pathogenic bacteria-induced infection. Understanding the principles of Host-Microbiota Interactions (HMIs) is important because it clarifies our insight towards the mechanisms of infections established in the host. Interactions between the host and the microbiota help answer the question of how a microorganism can contribute to the health or disease of the host. Microbiota can increase host resistance to colonization of pathogenic species. Studying the HMIs network can in several ways delineate the pathogenic mechanisms of pathogens and thereby help to increase useful and novel therapeutic pathways. For example, the potentially unique microbial effects that target the distinct host or interfere with the endogenous host interactions can be identified. In addition, the way mutations in essential proteins in the host and/or in the microbes can influence the interactions between them may be determined. Furthermore, HMIs help in identifying host cell regulatory modules.

Identification of bioactive metabolites and evaluation of in vitro anti-inflammatory and in vivo antinociceptive and antiarthritic activities of endophyte fungi isolated from Elaeocarpus floribundus blume. JOURNAL OF ETHNOPHARMACOLOGY 2021; 273:113975. [PMID: 33652111 DOI: 10.1016/j.jep.2021.113975] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/25/2020] [Revised: 02/22/2021] [Accepted: 02/23/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Functional disability associated with rheumatoid arthritis (RA), a chronic inflammatory autoimmune disease is a challenging concern in healthcare systems. Along with environmental factors and epigenetic disorders, multiple pathways are reported as prominent mechanism for the progression of RA symptoms including; pain, swelling and stiffness of joints. Elaeocarpus floribundus Blume has been used as a folklore medicine for RA from ancient times. This plant harbours a suite of endophytic fungi that produce a range of metabolites of potential interest. Thus, for the establishment of a scientific basis for this folklore use, it is essential to find out the involvement, if any, of the endophytic fungi living in this plant and the metabolites they elaborate, for the management of RA. AIM OF THE STUDY This study was designed to isolate, identify and evaluate the in vitro anti-inflammatory and in vivo antinociceptive and antiarthritic activities of the compounds produced by the endophytic fungi living in different parts of Elaeocarpus floribundus Blume. MATERIALS AND METHODS Endophytic fungi from different parts of the plant were isolated and cultured for the production of secondary metabolites. Chromatographically fractionated fungal extracts were assessed for anti-inflammatory and antinociceptive activities. For the evaluation of anti-inflammatory activity, in vitro cyclooxygenase (COX1/COX2) and 5-lipoxygenase (5-LOX) inhibitory assays were performed. For the evaluation of in vivo antinociceptive activity, hot plate acetic acid induced writhing, and formalin induced paw licking methods were adopted, whereas complete Freund's adjuvant (CFA) induced poly-arthritic method was adopted for the evaluation of antiarthritic activity. The most effective fraction was analyzed by liquid chromatography-mass spectroscopy (LC-MS) in search of the bioactive extracellular metabolites. RESULTS Five endophytic fungi viz. Aspergillus fumigatus, Aspergillus niger, Rhizoctonia oryzae, Rhizopus oryzae, and Syncephalastrum racemosum were isolated. COX1/COX2 and 5-LOX inhibitory assays state that the Aspergillus niger fraction possesses the greatest activity against these enzymes of inflammatory process. In vivo antinociceptive showed significant (***P<0.001) reduction of pain in a dose dependent manner. As well, significant (***P<0.001) reduction of paw volume was observed in CFA induce poly-arthritic test. LC/MS analysis of the Aspergillus niger fraction revealed the presence of bioactive compounds including tensyuic acid, hexylitaconic acid, chlorogenic acid, nigragillin, TMC-256C1, asnipyrone B, asperenone, fumaric acid and fusarubin, all having reported pharmacological activities. CONCLUSION The present study demonstrates that secondary metabolites produced by endophytic fungi living in various parts of Elaeocarpus floribundus Blume had potential to relief pain and inflammation. The endophytes were found to contain multiple biomolecules effective in rheumatoid arthritis. These findings provide a rationale for the folklore use of the plant in the management of rheumatoid arthritis.

Abstract
Antimicrobial peptides (AMPs), which hold tremendous promise in overcoming the emergence of drug resistance, are limited in wide clinical applications due to their instability, especially against trypsin. Herein, we designed six peptide mutants based on the cathelicidin CATHPb2, followed by screening. Pb2-1, which showed the best activity against drug-resistant bacteria among these mutants, was selected to be combined with the trypsin inhibitory loop ORB-C to obtain two hybrid peptides: PCL-1 and Pb2-1TI. Notably, both of the hybrid peptides exhibited a remarkable enhancement in trypsin resistance compared with Pb2-1. The tests showed that PCL-1 displayed broad-spectrum antimicrobial activity that was superior to that of Pb2-1TI. In addition, PCL-1 had relatively lower cytotoxicity than Pb2-1TI towards the L02 and HaCaT cell lines and negligible hemolysis, as well as tolerance to high concentrations of salt, extreme pH, and temperature variations. In vivo, PCL-1 effectively improved the survival rate of mice that were systemically infected with drug-resistant Escherichia coli through efficient bacterial clearance from the blood and organs. With regard to mode of action, PCL-1 damaged the integrity of the bacterial cell membrane and attached to the membrane surface while bound to bacterial genomic DNA to eventually kill the bacteria. Altogether, the trypsin-resistant peptide PCL-1 is expected to be a candidate for the clinical treatment of bacterial infections.

Abstract
OBJECTIVE Malaria is an infectious parasitic disease affecting most of countries worldwide. Due to antimalarial drug resistance, researchers are seeking to find another safe efficient source for treatment of malaria. Since many years ago, medicinal plants were widely used for the treatment of several diseases. In general, most application is done first on experimental animals then human. In this article, medicinal plants as antimalarial agents in experimental animals were reviewed from January 2000 until November 2020. MATERIALS AND METHODS In this systematic review published articles were reviewed using the electronic databases NCBI, ISI Web of knowledge, ScienceDirect and Saudi digital library to check articles and theses for M.Sc/Ph.D. The name of the medicinal plant with its taxon ID and family, the used Plasmodium species, plant part used and its extract type and the country of harvest were described. RESULTS AND CONCLUSION The reviewed plants belonged to 83 families. Medicinal plants of families Asteraceae, Meliaceae Fabaceae and Lamiaceae are the most abundant for use in laboratory animal antimalarial studies. According to region, published articles from 33 different countries were reviewed. Most of malaria published articles are from Africa especially Nigeria and Ethiopia. Leaves were the most common plant part used for the experimental malaria research. In many regions, research using medicinal plants to eliminate parasites and as a defensive tool is popular.

Abstract
The spread of multi-drug resistance and the slow pace at which antibiotics come onto the market are undermining our ability to treat human infections, leading to high mortality rates. Aiming to overcome this global crisis, antimicrobial peptides are considered promising alternatives to counter bacterial infections with multi-drug resistant bacteria. The cathelicidins comprise a well-studied class of AMPs whose members have been used as model molecules for sequence modifications, aiming at enhanced biological activities and stability, along with reduced toxic effects on mammalian cells. Here, we describe the antimicrobial activities, modes of action and structural characterization of two novel cathelicidin-like peptides, named BotrAMP14 and CrotAMP14, which were re-designed from snake batroxicidin and crotalicidin, respectively. BotrAMP14 and CrotAMP14 showed broad-spectrum antibacterial activity against susceptible microorganisms and clinical isolates with minimal inhibitory concentrations ranging from 2–35.1 μM. Moreover, both peptides had low cytotoxicity against Caco-2 cells in vitro. In addition, in vivo toxicity against Galleria mellonella moth larvae revealed that both peptides led to>76% larval survival after 144 h. Microscopy studies suggest that BotrAMP14 and CrotAMP14 destabilize E. coli membranes. Furthermore, circular dichroism and molecular dynamics simulations indicate that, in a membrane-like environment, both peptides adopt α-helical structures that interact with bilayer phospholipids through hydrogen bonds and electrostatic interaction. Thus, we concluded that BotrAMP14 and CrotAMP14 are helical membrane active peptides, with similar antibacterial properties but lower cytotoxicity than the larger parent peptides batroxicidin and crotalicidin, having advantages for drug development strategies.

Abstract
Escalating antibiotic resistance is now a serious menace to global public health. It may be led to the emergence of "postantibiotic age" in which most of infections are untreatable. At present, there is an essential need to explore novel therapeutic strategies as a strong and sustainable pipeline to combat antibiotic-resistant infections. This review focuses on recent advances in this area including therapeutic antibodies, antimicrobial peptides, vaccines, gene therapy, genome editing, and phage therapy for tackling drug-resistant infections.

Abstract
The discovery of novel antimicrobials from animal species under pollution is an area untapped. Chinese red-headed centipede is one of the hardiest arthropod species commonly known for its therapeutic value in traditional Chinese medicine. Here we determined the antibacterial activity of haemolymph and tissue extracts of red-headed centipede, Scolopendra subspinipes against a panel of Gram-positive and Gram-negative bacteria. Lysates exhibited potent antibacterial activities against a broad range of bacteria tested. Chemical characterization of biologically active molecules was determined via liquid chromatography mass spectrometric analysis. From crude haemolymph extract, 12 compounds were identified including: (1) L-Homotyrosine, (2) 8-Acetoxy-4-acoren-3-one, (3) N-Undecylbenzenesulfonic acid, (4) 2-Dodecylbenzenesulfonic acid, (5) 3H-1,2-Dithiole-3-thione, (6) Acetylenedicarboxylate, (7) Albuterol, (8) Tetradecylamine, (9) Curcumenol, (10) 3-Butylidene-7-hydroxyphthalide, (11) Oleoyl Ethanolamide and (12) Docosanedioic acid. Antimicrobial activities of the identified compounds were reported against Gram-positive and Gram-negative bacteria, fungi, viruses and parasites, that possibly explain centipede's survival in harsh and polluted environments. Further research in characterization, molecular mechanism of action and in vivo testing of active molecules is needed for the development of novel antibacterials.

Abstract
Endophytic Streptomyces strains are potential sources for novel bioactive molecules. In this study, the diketopiperazine gancidin W (GW) was isolated from the endophytic actinobacterial genus Streptomyces, SUK10, obtained from the bark of Shorea ovalis tree, and it was tested in vivo against Plasmodium berghei PZZ1/100. GW exhibited an inhibition rate of nearly 80% at 6.25 and 3.125 μg kg-1 body weight on day four using the 4-day suppression test method on male ICR strain mice. Comparing GW at both concentrations with quinine hydrochloride and normal saline as positive and negative controls, respectively, 50% of the mice treated with 3.125 μg kg-1 body weight managed to survive for more than 11 months after infection, which almost reached the life span of normal mice. Biochemical tests of selected enzymes and proteins in blood samples of mice treated with GW were also within normal levels; in addition, no abnormalities or injuries were found on internal vital organs. These findings indicated that this isolated bioactive compound from Streptomyces SUK10 exhibits very low toxicity and is a good candidate for potential use as an antimalarial agent in an animal model.

[PMID: 28035594 DOI: 10.1007/s12275-017-6452-1] [Citation(s) in RCA: 237] [Impact Index Per Article: 29.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2016] [Revised: 11/02/2016] [Accepted: 11/04/2016] [Indexed: 11/30/2022]
Abstract
Antimicrobial peptides (AMPs) are small molecules with a broad spectrum of antibiotic activities against bacteria, yeasts, fungi, and viruses and cytotoxic activity on cancer cells, in addition to anti-inflammatory and immunomodulatory activities. Therefore, AMPs have garnered interest as novel therapeutic agents. Because of the rapid increase in drug-resistant pathogenic microorganisms, AMPs from synthetic and natural sources have been developed using alternative antimicrobial strategies. This article presents a broad analysis of patents referring to the therapeutic applications of AMPs since 2009. The review focuses on the universal trends in the effective design, mechanism, and biological evolution of AMPs.

Isolation and antimicrobial activities of actinobacteria closely associated with liquorice plants Glycyrrhiza glabra L. and Glycyrrhiza inflate BAT. in Xinjiang, China.

Abstract
A total of 218 actinobacteria strains were isolated from wild perennial liquorice plants Glycyrrhiza glabra L. and Glycyrrhiza. inflate BAT. Based on morphological characteristics, 45 and 32 strains from G. inflate and G. glabra, respectively, were selected for further analyses. According to 16S rRNA sequence analysis, most of the strains belonged to genus Streptomyces and a few strains represented the rare actinobacteria Micromonospora, Rhodococcus and Tsukamurella. A total of 39 strains from G. inflate and 27 strains from G. glabra showed antimicrobial activity against at least one indicator organism. The range of the antimicrobial activity of the strains isolated from G. glabra and G. inflate was similar. A total of 34 strains from G. inflate and 29 strains from G. glabra carried at least one of the genes encoding polyketide synthases, non-ribosomal peptide synthetase and FADH2-dependent halogenase. In the type II polyketide synthase KSα gene phylogenetic analysis, the strains were divided into two major clades: one included known spore pigment production-linked KSα sequences and other sequences were linked to the production of different types of aromatic polyketide antibiotics. Based on the antimicrobial range, the isolates that carried different KSα types were not separated from each other or from the isolates that did not carry KSα. The incongruent phylogenies of 16S rRNA and KSα genes indicated that the KSα genes were possibly horizontally transferred. In all, the liquorice plants were a rich source of biocontrol agents that may produce novel bioactive compounds.
