Abstract
Cancer has emerged as a potentially lethal illness, which recently upsurged in the mortality rate. Animal-derived compounds could be promising targets with higher efficacy and low toxicity in anticancer therapy. The present study aimed to explore the presence of anticancer potential compounds in Hirudinaria manillensis methanolic extract and their anticancer potential against various cancer cell types and target identification by Auto dock method. Initially, the identification of bioactive compounds was achieved by GC-MS analysis followed by the anticancer activity by MTT assay against A549, HeLa, MDA-MB-231, MG-63, and MOLT-4. Further, the effect of a lead compound on the cancer cell target was analyzed by the Auto dock method. GC-MS analysis results revealed the presence of 25 different bioactive compounds including anticancer potential compounds, such as Lupeol, Carvacrol, and Demecolcine. Interestingly, MTT assay results demonstrated the anticancer potential of Hirudinaria manillensis extract (LE) against various cancer cell lines, such as A549 (54.60 µg/ml), HeLa (19.93 µg/ml), MDA-MB-231 (20.23 µg/ml), MG-63 (20.04 µg/ml), and MOLT-4 (171.8 µg/ml), respectively. Among these cell types, the maximum inhibition was observed against HeLa with the IC50 concentration of 19.93 µg/ml. Furthermore, Demecolcine compound was docked with the EGFR tyrosine kinase showed the binding affinity of the docked complex was predicted to be - 6.2 kcal/mol. Thus, we conclude that H. manillensis has a significant anticancer effect on human cancer cell lines and could be used as a natural target which paves the way for further studies on biomedical applications in cancer therapeutics.

An ensemble docking-based virtual screening and molecular dynamics simulation of phytochemical compounds from Malaysian Kelulut Honey (KH) against SARS-CoV-2 target enzyme, human angiotensin-converting enzyme 2 (ACE-2). J Biomol Struct Dyn 2024:1-30. [PMID: 38279932 DOI: 10.1080/07391102.2024.2308762] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Accepted: 01/17/2024] [Indexed: 01/29/2024]
Abstract
The human angiotensin-converting enzyme 2 (ACE-2) receptor is a metalloenzyme that plays an important role in regulating blood pressure by modulating angiotensin II. This receptor facilitates SARS-CoV-2 entry into human cells via receptor-mediated endocytosis, causing the global COVID-19 pandemic and a major health crisis. Kelulut honey (KH), one of Malaysian honey recently gained attention for its distinct flavour and taste while having many nutritional and medicinal properties. Recent study demonstrates the antiviral potential of KH against SARS-CoV-2 by inhibiting ACE-2 in vitro, but the bioactive compound pertaining to the ACE-2 inhibition is yet unknown. An ensemble docking-based virtual screening was employed to screen the phytochemical compounds from KH with high binding affinity against the 10 best representative structures of ACE-2 that mostly formed from MD simulation. From 110 phytochemicals previously identified in KH, 27 compounds passed the ADMET analysis and proceeded to docking. Among the docked compound, SDC and FMN consistently exhibited strong binding to ACE-2's active site (-9.719 and -9.473 kcal/mol) and allosteric site (-7.305 and -7.464 kcal/mol) as compared to potent ACE-2 inhibitor, MLN 4760. Detailed trajectory analysis of MD simulation showed stable binding interaction towards active and allosteric sites of ACE-2. KH's compounds show promise in inhibiting SARS-CoV-2 binding to ACE-2 receptors, indicating potential for preventive use or as a supplement to other COVID-19 treatments. Additional research is needed to confirm KH's antiviral effects and its role in SARS-CoV-2 therapy, including prophylaxis and adjuvant treatment with vaccination.Communicated by Ramaswamy H. Sarma.

Abstract
Recent years have seen a lot of interest in mycosporine-like amino acids (MAAs) because of their alleged potential as a natural microbial sunscreen. Since chemical ultraviolet (UV) absorbers are unsafe for long-term usage, the demand for natural UV-absorbing substances has increased. In this situation, MAA is a strong contender for an eco-friendly UV protector. The capacity of MAAs to absorb light in the UV-A (320-400 nm) and UV-B (280-320 nm) range without generating free radicals is potentially relevant in photoprotection. The usage of MAAs for purposes other than photoprotection has now shifted in favor of medicinal applications. Aside from UV absorption, MAAs also have anti-oxidant, anti-inflammatory, wound-healing, anti-photoaging, cell proliferation stimulators, anti-cancer agents, and anti-adipogenic properties. Recently, MAAs application to combat SARS-CoV-2 infection was also investigated. In this review article, we highlight the biomedical applications of MAAs that go beyond photoprotection, which can help in utilizing the MAAs as promising bioactive compounds in both pharmaceutical and cosmetic applications.

Abstract
Cobalt(II) complexes of biphenyl-2-ol of composition, CoCl2-n(OC6H4C6H5-2)n(H2O)4 (where n = 1 or 2), were prepared by reacting cobaltous(II) chloride with equi- and bimolar ratios of sodium salt of biphenyl-2-ol. The structural characterization of the synthesized complexes was accomplished by NMR, FTIR, thermogravimetry (TGA), high resolution mass spectroscopy (HRMS), electronic spectroscopic techniques coupled with density functional theory (DFT). The stability of the complexes in different pH media of solvent was studied. Chemical reactivity parameters of the newly synthesized complexes, computed using DFT, indicated greater reactivity of complex 2 over complex 1 and free ligand as indicated by its low HOMO-LUMO energy gap corresponding to 1.71 eV. Molecular docking (MD) studies were carried out in order to study the binding affinities between amino acid residues of DNA duplex (PDB ID: 1BNA) and SARS-CoV-2 (PDB ID: 7T9K) with newly synthesized complexes. Complex 2 has shown promising antivirus behaviour with an inhibition constant value of 0.0423 µmol-1 with amino acid residues of SARS-CoV-2 virus. Toxicity of the complexes was predicted using ProTox-II online server. Antibacterial studies have indicated the complexes to exhibit greater efficacy than the free ligand, while the antioxidant activities have suggested them to display enhanced antioxidant behaviour as compared to reference compounds.Communicated by Ramaswamy H.

Abstract
Despite the advances in contemporary medicine and availability of numerous innovative therapies, effective treatment and prevention of SARS-CoV-2 infections pose a challenge. In the search for new anti-SARS-CoV-2 drug candidates, natural products are frequently explored. Here, fifteen cyanopeptolins (CPs) were isolated from the Baltic cyanobacterium Nostoc edaphicum and tested against SARS-CoV-2. Of these depsipeptides, the Arg-containing structural variants showed the strongest inhibition of the Delta SARS-CoV-2 infection in A549ACE2/TMPRSS2 cells. The functional assays indicated a direct interaction of the Arg-containing CP978 with the virions. CP978 also induced a significant decline in virus replication in the primary human airway epithelial cells (HAE). Of the four tested SARS-CoV-2 variants, Wuhan, Alpha, Omicron and Delta, only Wuhan was not affected by CP978. Finally, the analyses with application of confocal microscopy and with the SARS-CoV-2 pseudoviruses showed that CP978-mediated inhibition of viral infection results from the direct binding of the cyanopeptolin with the coronaviral S protein. Considering the potency of viral inhibition and the mode of action of CP978, the significance of the peptide as antiviral drug candidate should be further explored.

Abstract
The COVID-19 pandemic has spurred intense research efforts to identify effective treatments for SARS-CoV-2. In silico studies have emerged as a powerful tool in the drug discovery process, particularly in the search for drug candidates that interact with various SARS-CoV-2 receptors. These studies involve the use of computer simulations and computational algorithms to predict the potential interaction of drug candidates with target receptors. The primary receptors targeted by drug candidates include the RNA polymerase, main protease, spike protein, ACE2 receptor, and transmembrane protease serine 2 (TMPRSS2). In silico studies have identified several promising drug candidates, including Remdesivir, Favipiravir, Ribavirin, Ivermectin, Lopinavir/Ritonavir, and Camostat Mesylate, among others. The use of in silico studies offers several advantages, including the ability to screen a large number of drug candidates in a relatively short amount of time, thereby reducing the time and cost involved in traditional drug discovery methods. Additionally, in silico studies allow for the prediction of the binding affinity of the drug candidates to target receptors, providing insight into their potential efficacy. This study is aimed at assessing the useful contributions of the application of computational instruments in the discovery of receptors targeted in SARS-CoV-2. It further highlights some identified advantages and limitations of these studies, thereby revealing some complementary experimental validation to ensure the efficacy and safety of identified drug candidates.

Abstract
SARS-CoV-2 as a zoonotic virus has significantly affected daily life and social behavior since its outbreak in late 2019. The concerns over its transmission through different media directly or indirectly have evoked great attention about the survival of SARS-CoV-2 virions in the environment and its potential infection of other animals. To evaluate the risk of infection by SARS-CoV-2 and to counteract the COVID-19 disease, extensive studies have been performed to understand SARS-CoV-2 biogenesis and its pathogenesis. This review mainly focuses on the molecular architecture of SARS-CoV-2, its potential for infecting marine animals, and the prospect of drug discovery using marine natural products to combat SARS-CoV-2. The main purposes of this review are to piece together progress in SARS-CoV-2 functional genomic studies and antiviral drug development, and to raise our awareness of marine animal safety on exposure to SARS-CoV-2.
