[PMID: 38185432 DOI: 10.1016/j.biotechadv.2024.108307] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 12/05/2023] [Accepted: 01/01/2024] [Indexed: 01/09/2024]
Abstract
Bioassays are the main tool to decipher bioactivities from natural resources thus their selection and quality are critical for optimal bioprospecting. They are used both in the early stages of compounds isolation/purification/identification, and in later stages to evaluate their safety and efficacy. In this review, we provide a comprehensive overview of the most common bioassays used in the discovery and development of new bioactive compounds with a focus on marine bioresources. We present a comprehensive list of practical considerations for selecting appropriate bioassays and discuss in detail the bioassays typically used to explore antimicrobial, antibiofilm, cytotoxic, antiviral, antioxidant, and anti-ageing potential. The concept of quality control and bioassay validation are introduced, followed by safety considerations, which are critical to advancing bioactive compounds to a higher stage of development. We conclude by providing an application-oriented view focused on the development of pharmaceuticals, food supplements, and cosmetics, the industrial pipelines where currently known marine natural products hold most potential. We highlight the importance of gaining reliable bioassay results, as these serve as a starting point for application-based development and further testing, as well as for consideration by regulatory authorities.

Abstract
The n-butanol fraction (BF) obtained from the crude extract of the marine sponge Petromica citrina, the halistanol-enriched fraction (TSH fraction), and the isolated compounds halistanol sulfate (1) and halistanol sulfate C (2), were evaluated for their inhibitory effects on the replication of the Herpes Simplex Virus type 1 (HSV-1, KOS strain) by the viral plaque number reduction assay. The TSH fraction was the most effective against HSV-1 replication (SI = 15.33), whereas compounds 1 (SI = 2.46) and 2 (SI = 1.95) were less active. The most active fraction and these compounds were also assayed to determine the viral multiplication step(s) upon which they act as well as their potential synergistic effects. The anti-HSV-1 activity detected was mediated by the inhibition of virus attachment and by the penetration into Vero cells, the virucidal effect on virus particles, and by the impairment in levels of ICP27 and gD proteins of HSV-1. In summary, these results suggest that the anti-HSV-1 activity of TSH fraction detected is possibly related to the synergic effects of compounds 1 and 2.

Abstract
Background Achillea kellalensis, which is frequently used by Chaharmahal va Bakhtiarians residing in, Southwest of Iran, as a traditional herbal medicine for the treatment of acute diarrhea, has been selected to examine its antiviral activities against bovine rotavirus and cell toxicity activity in MA-104 cells. Objectives The aim of this study was to evaluate the in vitro cytotoxic and anti-rotavirus properties of crude extracts of A. kellalensis. Materials and Methods The dried and powdered flowers of Achillea kellalensis were extracted with hot water and ethanol 50% (v/v). The cell viability and toxicity of the extracts were evaluated on MA-104 cells using four methods; trypan blue dye, NR, crystal violet and MTT assay. The in vitro anti-rotavirus properties were determined via four different assays, in order to evaluate the direct inhibition and/or the inhibition of viral replication. Results Cytotoxicity of two A. kellalensis extracts showed different concentrations. Hydro-alcoholic extract had low CC50 at 600 µg/mL by the NR assay while the aqueous extract had high CC50 at 1000µg/mL by the crystal violet method. In the simultaneous treatment assay and post treatment assay, the extracts were able to prevent viral replication and inhibit the viral CPE on MA-104 cells at 10 TCID50, but the extracts did not exhibit direct antiviral activity on rotavirus adsorption. The effective concentration (EC50) of both extracts was observed to be 100 µg/mL. Conclusions These results indicate that A. kellalensis extracts exert potent anti-rotaviral activity only after viral adsorption. The two extracts from A. kellalensis showed a good selectivity index. Also these results suggest that extracts prepared from the flowers of A. kellalensis may be potential anti-rotaviral agents in vivo and be useful in veterinary medicine.

Abstract
This manuscript describes the evaluation of anti-infective potential in vitro of organic extracts from nine sponges, one ascidian, two octocorals, one bryozoan, and 27 seaweed species collected along the Brazilian coast. Antimicrobial activity was tested against Staphylococcus aureus (ATCC 25923), Enterococcus faecalis (ATCC 29212), Pseudomonas aeruginosa (ATCC 27853), Escherichia coli (ATCC 25922) and Candida albicans (ATCC 10231) by the disk diffusion method. Antiprotozoal activity was evaluated against Leishmania braziliensis (MHOM/BR/96/LSC96-H3) promastigotes and Trypanosoma cruzi (MHOM/BR/00/Y) epimastigotes by MTT assay. Activity against intracellular amastigotes of T. cruzi and L. brasiliensis in murine macrophages was also evaluated. Antiviral activity was tested against Herpes Simplex Virus type 1 (HSV-1, KOS strain) by the plaque number reduction assay (IC50). Cytotoxicity on VERO cells was evaluated by the MTT assay (CC50). The results were expressed as SI = CC50/IC50. The most promising antimicrobial results were obtained against S. aureus and C. albicans with Dragmacidon reticulatum. Among the seaweeds, only Osmundaria obtusiloba showed moderate activity against P. aeruginosa. Concerning antiprotozoal activity, Bugula neritina, Carijoa riseii, Dragmaxia anomala and Haliclona (Halichoclona) sp. showed the most interesting results, mainly against extracellular promastigote forms of L. braziliensis (66, 35.9, 97.2, and 43.6% inhibition, respectively). Moreover, six species of seaweeds Anadyomene saldanhae, Caulerpa cupressoides, Canistrocarpus cervicornis, Dictyota sp., Ochtodes secundiramea, and Padina sp. showed promising results against L. braziliensis (87.9, 51.7, 85.9, 93.3, 99.7, and 80.9% inhibition, respectively), and only Dictyota sp. was effective against T. cruzi (60.4% inhibition). Finally, the antiherpes activity was also evaluated, with Haliclona (Halichoclona) sp. and Petromica citrina showing the best results (SI = 11.9 and SI > 5, respectively). All the active extracts deserve special attention in further studies to chemically characterize the bioactive compounds, and to perform more refined biological assays.

Abstract
Lectin II from the marine sponge Axinella corrugata (ACL-II) was purified by affinity chromatography on rabbit erythrocytic stroma incorporated into a polyacrylamide gel, followed by gel filtration on Ultrogel AcA 44 column. Purified ACL-II is a lectin with an Mr of 80 kDa and 78 kDa, estimated by SDS-PAGE and by FPLC on Superose 12 HR column, respectively. ACL-II mainly agglutinates native rabbit erythrocytes and this hemagglutinating activity is independent of Ca(2+), Mg(2+) and Mn(2+), but is inhibited by d-galactose, chitin and N-acetyl derivatives, with the exception of GalNAc. ACL-II is stable for up to 65 °C for 30 min, with a better stability at a pH range of 2 to 6. In contrast, ACL-I displays a strong mitogenic and cytotoxic effect.

Abstract
Mexican oregano (Lippia graveolens) is a plant found in Mexico and Central America that is traditionally used as a medicinal herb. In the present study, we investigated the antiviral activity of the essential oil of Mexican oregano and its major component, carvacrol, against different human and animal viruses. The MTT test (3–4,5-dimethythiazol-2yl)-2,5-diphenyl tetrazolium bromide) was conducted to determine the selectivity index (SI) of the essential oil, which was equal to 13.1, 7.4, 10.8, 9.7, and 7.2 for acyclovir-resistant herpes simplex virus type 1 (ACVR-HHV-1), acyclovir-sensitive HHV-1, human respiratory syncytial virus (HRSV), bovine herpesvirus type 2 (BoHV-2), and bovine viral diarrhoea virus (BVDV), respectively. The human rotavirus (RV) and BoHV-1 and 5 were not inhibited by the essential oil. Carvacrol alone exhibited high antiviral activity against RV with a SI of 33, but it was less efficient than the oil for the other viruses. Thus, Mexican oregano oil and its main component, carvacrol, are able to inhibit different human and animal viruses in vitro. Specifically, the antiviral effects of Mexican oregano oil on ACVR-HHV-1 and HRSV and of carvacrol on RV justify more detailed studies.

Abstract
The present study was conducted to evaluate the antioxidant, anti-inflammatory, and antiproliferative activities of organic fractions from Cystoseira sedoides (Desfontaines) C. Agardh . Various fractions of C. sedoides (chloroform (F-CHCl3), ethyl acetate (F-AcOEt), and methanol (F-MeOH)) were screened for total phenol content, as well as antioxidant activity, using the stable radical 1,1-diphenyl-2-picrylhydrazyl (DPPH), and assays for determining the reducing power of these fractions. The anti-inflammatory properties of these fractions were assessed using the carrageenan-induced rat paw oedema model. The antiproliferative activity of C. sedoides fractions was evaluated on normal Madin–Darby canine kiney (MDCK), and fibroblast cells and on cancer cell lines (A549, MCF7, and HCT15), using the ability of the cells to metabolically reduce 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) formazan dyes. The F-CHCl3 and F-AcOEt fractions showed significant total phenolic content at 55.09 and 61.30 mg gallic-acid equivalent/g dried sample, respectively. Using the DPPH method, the F-CHCl3 and the F-AcOEt fractions exhibited the strongest radical scavenging activity, with IC50 120 µg/mL for F-CHCl3 and 121 µg/mL for F-AcOEt, which approaches the activity of the powerful antioxidant standard, Trolox (IC50 = 90 µg/mL). The reducing power of the samples was in the following order: F-AcOEt > F-CHCl3 > F-MeOH fraction. The F-CHCl3 and F-AcOEt fractions of C. sedoides tested at different doses (25 and 50 mg/kg, intraperitoneally (i.p)), exhibited a dose-dependent reduction of rat paw oedema. The percentage of inhibition of oedema, 3 h after carrageenan injection, ranged from 67.71% to 73.49% and from 67.74% to 74.58%, for F-CHCl3 and F-AcOEt, respectively. Their effects are comparable with that of lysine acetylsalicylate (300 mg/kg body mass; i.p.), which is used as a reference drug with the ability to inhibit oedema by 66.14%. Our results revealed that the F-CHCl3 and F-AcOEt fractions from C. sedoides showed important antiproliferative properties towards all of the cancer cell lines studied here, as judged by their IC50 values, which ranged from 52.6 to 66.5 µg/mL for A549; 22.4 to 70.2 µg/mL for MCF7, and 250.6 to 255.3 µg/mL for HCT15. Moreover, no visible destruction or alteration of normal cells was observed, even at 500 µg/mL F-CHCl3 or F-AcOEt. These results suggest that C. sedoides fractions might be used as a potential source of natural antioxidant, anti-inflammatory, and antitumor agents. The purification and determination of the chemical structures of the compounds in these active fractions are under investigation. The results could provide a compound(s) with a promising role in future medicines and nutrition, when used either as a drug or a dietary supplement.

Abstract
The antiviral activities of extracts from Daucus maritimus seeds were investigated against the reverse transcriptase of human immunodeficiency virus (HIV) type 1 and a panel of RNA-dependent RNA polymerases of dengue virus, West Nile virus (WNV) and hepatitis C virus (HCV). The extracts showed moderate to potent inhibition rates against the four viral polymerases. The ethyl acetate extract exhibited a potent inhibitory effect against WNV's RdRp, with an IC₅₀ value of 8 µg mL⁻¹. The F₂ fraction exhibited potent inhibitory activity against WNV and HCV's RdRps, with IC₅₀ values 1 and 5 µg mL⁻¹, respectively. The P₂ fraction also showed potent inhibitory effects on WNV and HCV's RdRps, with IC₅₀ values 2.7 and 4 µg mL⁻¹, respectively. The results suggest that these extracts are candidates for the development of new anti-WNV RpDp and anti-HCV RpDp agents.

Abstract
In vitro anti-rotavirus activity of Alpinia katsumadai (AK) extracts were evaluated against bovine G8P[7] and porcine G5P[7] rotaviruses in two different assay strategies, a mixed treatment assay and a post treatment assay. In the mixed treatment assay, six AK extracts [AK-1 (EtOH extract), AK-3 (H2O layer), AK-5 (40% methanol fraction), and AK-9–11 (H2O extract, polysaccharide fraction, supernatant fraction)] exhibited inhibitory activities against G5P[7] rotavirus with the EC50 values ranging from 0.7 ± 0.4 to 33.7 ± 6.5 μg/mL. Extracts AK-1, AK-3, and AK-5 inhibited rotavirus infection against G8P[7] rotavirus, the with EC50 values of 8.4 ± 2.2 μg/mL, 6.5 ± 0.8 μg/mL and 8.4 ± 5.0 μg/mL, respectively. By hemagglutination inhibition (HI) assay, six AK extracts completely inhibited viral adsorption onto human RBCs in both strains of rotaviruses at less than 11 μg/mL. However, in the post treatment assay, there was no anti activity shown against both strains of rotaviruses. As a result, six AK extracts were attributed mainly to having a strong interaction with hemagglutinin protein on the outer surface of rotavirus, resulting to blockage of viral adsorption.

Abstract
Marine sponges are currently one of the richest sources of pharmacologically active compounds found in the marine environment. These bioactive molecules are often secondary metabolites, whose main function is to enable and/or modulate cellular communication and defense. They are usually produced by functional enzyme clusters in sponges and/or their associated symbiotic microorganisms. Natural product lead compounds from sponges have often been found to be promising pharmaceutical agents. Several of them have successfully been approved as antiviral agents for clinical use or have been advanced to the late stages of clinical trials. Most of these drugs are used for the treatment of human immunodeficiency virus (HIV) and herpes simplex virus (HSV). The most important antiviral lead of marine origin reported thus far is nucleoside Ara-A (vidarabine) isolated from sponge Tethya crypta. It inhibits viral DNA polymerase and DNA synthesis of herpes, vaccinica and varicella zoster viruses. However due to the discovery of new types of viruses and emergence of drug resistant strains, it is necessary to develop new antiviral lead compounds continuously. Several sponge derived antiviral lead compounds which are hopedto be developed as future drugs are discussed in this review. Supply problems are usually the major bottleneck to the development of these compounds as drugs during clinical trials. However advances in the field of metagenomics and high throughput microbial cultivation has raised the possibility that these techniques could lead to the cost-effective large scale production of such compounds. Perspectives on biotechnological methods with respect to marine drug development are also discussed.

Abstract
Viral-induced infectious diseases represent a major health threat and their control remains an unachieved goal, due in part to the limited availability of effective anti-viral drugs and measures. The use of natural products in drug manufacturing is an ancient and well-established practice. Marine organisms are known producers of pharmacological and anti-viral agents. In this study, a total of 20 extracts from marine microorganisms were evaluated for their antiviral activity. These extracts were tested against two mammalian viruses, herpes simplex virus (HSV-1) and vesicular stomatitis virus (VSV), using Vero cells as the cell culture system, and two marine virus counterparts, channel catfish virus (CCV) and snakehead rhabdovirus (SHRV), in their respective cell cultures (CCO and EPC). Evaluation of these extracts demonstrated that some possess antiviral potential. In sum, extracts 162M(4), 258M(1), 298M(4), 313(2), 331M(2), 367M(1) and 397(1) appear to be effective broad-spectrum antivirals with potential uses as prophylactic agents to prevent infection, as evident by their highly inhibitive effects against both virus types. Extract 313(2) shows the most potential in that it showed significantly high inhibition across all tested viruses. The samples tested in this study were crude extracts; therefore the development of antiviral application of the few potential extracts is dependent on future studies focused on the isolation of the active elements contained in these extracts.

Abstract
Available treatments for many infectious diseases are limited. In particular, diseases caused by viral pathogens have demonstrated the need for new medicines, due to the increasing appearance of resistance to these available treatments. Thousands of novel compounds have been isolated from various marine organisms and tested for pharmacological properties, many of which are commercially available. The screening of natural products derived from marine species for antiviral activity has yielded a considerable number of active crude aqueous and organic solvent extracts. Today, over 40 compounds are commercially available in pharmacological markets, including alternative antiviral medicines or those being tested as potential antiviral drugs. Many more are being tested as potential antiviral drugs at the preclinical and clinical stages. The growing interest in marine-derived antiviral compounds, along with the development of new technology in marine cultures and extraction, will significantly expedite the current exploration of the marine environment for compounds with significant pharmacological applications, which will continue to be a promising strategy and new trend for modern medicine.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Araucaria angustifolia (Bert.) O. Kuntze (Araucariaceae) is a Brazilian medicinal plant traditionally used for the treatment of various illnesses including dried skin, wounds, shingles, and sexually transmitted diseases. AIM OF THE STUDY The rationale of the study was to provide evidence of its antiherpes activity in order to confirm its popular use that could be related to herpes disease. MATERIALS AND METHODS The crude hydroethanolic extract (HE) obtained from Araucaria angustifolia leaves was submitted to a sequential liquid-liquid extraction with solvents of increased polarity. The HE and fractions obtained were evaluated for cytotoxicity and antiherpes activity (Herpes Simplex Virus type 1) by MTT assay. The most active fractions were selected to perform an in vitro antiviral activity-guided chromatographic fractionation. RESULTS The ethyl acetate (EA) and n-butanol (NB) fractions have shown the best results for antiherpetic activity and their further fractionation yielded 22 subfractions. From these subfractions, 14 were active, and the most potent antiherpetic activity was obtained for NB1-4 subfraction with selectivity index (SI) of 57.51. Chemical analysis of NB1-4 subfractions revealed the presence of proanthocyanidins and the known biflavonoids (bilobetin, II-7-O-methyl-robustaflavone and cupressuflavone). The same biflavonoids have been detected in EA subfractions. CONCLUSION The present study has shown that the hydroethanolic extract from Araucaria angustifolia leaves as well as many different fractions and subfractions exhibited antiherpes activity, supporting the use of this plant species in folk medicine.

Abstract
BACKGROUND The review presents the 2005-2006 peer-reviewed marine pharmacology literature, and follows a similar format to the authors' 1998-2004 reviews. The preclinical pharmacology of chemically characterized marine compounds isolated from marine animals, algae, fungi and bacteria is systematically presented. RESULTS Anthelmintic, antibacterial, anticoagulant, antifungal, antimalarial, antiprotozoal, antituberculosis and antiviral activities were reported for 78 marine chemicals. Additionally 47 marine compounds were reported to affect the cardiovascular, immune and nervous system as well as possess anti-inflammatory effects. Finally, 58 marine compounds were shown to bind to a variety of molecular targets, and thus could potentially contribute to several pharmacological classes. CONCLUSIONS Marine pharmacology research during 2005-2006 was truly global in nature, involving investigators from 32 countries, and the United States, and contributed 183 marine chemical leads to the research pipeline aimed at the discovery of novel therapeutic agents. GENERAL SIGNIFICANCE Continued preclinical and clinical research with marine natural products demonstrating a broad spectrum of pharmacological activity will probably result in novel therapeutic agents for the treatment of multiple disease categories.
