Abstract
Background
Macropanax dispermus is traditionally used to treat various diseases by ethnic people. The present research reports the pharmacological properties with phytochemical profiling of the crude extracts of M. dispermus leaves (MDML), its n-hexane (MDHL), carbon tetrachloride (MDTL), chloroform (MDCL), ethyl acetate (MDEL), and aqueous (MDAL) fractions, and crude methanol extracts of its stem barks (MDMS). The in vitro thrombolytic activity was done on human erythrocytes whereas the cytotoxic activity was done by brine shrimp lethality assay. The in vivo analgesic activity was examined by acetic acid-induced writhing, tail immersion, and formalin-induced paw licking method. In contrast, antipyretic activity was done by the brewer’s yeast-induced pyrexia method.
Results
MDHL and MDMS showed 37.05% and 42.21% of significant (p < 0.01) thrombolytic activity, respectively. MDCL and MDMS showed the lower LC50 values of 23.15 and 37.11 µg/ml during cytotoxicity test, respectively. In acetic acid writhing method, MDTL and MDEL showed significant (p < 0.001) inhibition of writhing by 79.34% and 80.17%, respectively. MDMS showed significant (p < 0.001) maximal possible effect (%MPE) of 45.95%, 62.26%, 65.79%, 89.69% and elongation of time in pain reaction of 48.53%, 60.28%, 58.76%, and 70.14% at 30, 60, 90, and 120 min intervals, respectively. MDML at 400 mg/kg exhibited significant (p < 0.001) 82.72% of inhibition of pain at the late phases. MDEL at 400 mg/kg of dose exhibited significant (p < 0.001) reduction of rectal temperature by 36.31%, 62.42%, 89.81%,, and 96.82% at 1, 2, 3, and 4 h intervals, respectively.
Conclusion
The current research suggests that the plant extracts possess potential thrombolytic, cytotoxic, analgesic, and antipyretic activities.

Abstract
With an increasing fatality rate, severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) has emerged as a promising threat to human health worldwide. Recently, the World Health Organization (WHO) has announced the infectious disease caused by SARS-CoV-2, which is known as coronavirus disease-2019 (COVID-2019), as a global pandemic. Additionally, the positive cases are still following an upward trend worldwide and as a corollary, there is a need for a potential vaccine to impede the progression of the disease. Lately, it has been documented that the nucleocapsid (N) protein of SARS-CoV-2 is responsible for viral replication and interferes with host immune responses. We comparatively analyzed the sequences of N protein of SARS-CoV-2 for the identification of core attributes and analyzed the ancestry through phylogenetic analysis. Subsequently, we predicted the most immunogenic epitope for the T-cell and B-cell. Importantly, our investigation mainly focused on major histocompatibility complex (MHC) class I potential peptides and NTASWFTAL interacted with most human leukocyte antigen (HLA) that are encoded by MHC class I molecules. Further, molecular docking analysis unveiled that NTASWFTAL possessed a greater affinity towards HLA and also available in a greater range of the population. Our study provides a consolidated base for vaccine design and we hope that this computational analysis will pave the way for designing novel vaccine candidates.

Abstract
With an increasing fatality rate, severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) has emerged as a promising threat to human health worldwide. SARS-CoV-2 is a member of the Coronaviridae family, which is transmitted from animal to human and because of being contagious, further it transmitted human to human. Recently, the World Health Organization (WHO) has announced the infectious disease caused by SARS-CoV-2, which is known as coronavirus disease-2019 (COVID-2019) as a global pandemic. But, no specific medications are available for the treatment of COVID-19 so far. As a corollary, there is a need for a potential vaccine to impede the progression of the disease. Lately, it has been documented that the nucleocapsid (N) protein of SARS-CoV-2 is responsible for viral replication as well as interferes with host immune responses.

Abstract
Abstract
Background
The study was conducted to evaluate the analgesic, anti-inflammatory, antipyretic properties of ethanolic extract of Tacca integrifolia rhizome (EETI) in mice and cytotoxic effects in brine shrimp nauplii followed by a PASS prediction study for some isolated compounds of T. integrifolia. Additionally, this experiment included the in silico molecular docking and ADME/T property analyses of some phytochemicals.
Methods
Formalin- induced paw licking test and acetic acid-induced writhing test for analgesic activity, carrageenan-induced paw edema test for anti-inflammatory potential and Brewer’s yeast-induced pyrexia test for antipyretic activity were applied. Antinociceptive and antineoplastic activity for breast cancer were revealed with PASS program. Schrodinger suite 2015 was used to evaluate the binding interaction and ADME/T properties of selected phytoconstituents with estrogen receptor alpha.
Results
In formalin-induced paw licking test, EETI at the doses of 200 and 400 mg/kg BW showed highly significant inhibition of writhing in both neurogenic and inflammatory phases. While EETI also exhibited highly significant, compared to control, writhing inhibition for both the doses in acetic acid-induced writhing test. Moderate anti-inflammatory effect at a dose of 400 mg/kg BW was noticed in paw-edema test. It also showed 77.51% of maximum antipyretic effect which was significantly effective compared to standard drug paracetamol (150 mg/kg) in Brewer’s yeast-induced pyrexia test. The EETI showed potential cytotoxic activity with LC50 value of 114.46 μg/mL. The PASS prediction revealed the potential antinociceptive and antineoplastic activity of target compounds. The compounds betulinic acid, quercetin-3-α-arabinoside, catsanogenin were found to be effective in molecular docking study.
Conclusion
It is evident that the EETI possesses highly significant analgesic activity with remarkable anti-inflammatory and antipyretic activity. The phytoconstituents have potential antinociceptive and antineoplastic (breast cancer) activity.
