Antiviral Activity of Ribosome-Inactivating Proteins

Toxins, 2021
Ribosome-inactivating proteins (RIPs) are rRNA N-glycosylases from plants (EC 3.2.2.22) that inactivate ribosomes thus inhibiting protein synthesis. The antiviral properties of RIPs have been investigated for more than four decades.

Inhibition of HIV-1 replication by balsamin, a ribosome inactivating protein of Momordica balsamina. [PDF]

PLoS ONE, 2013
Ribosome-inactivating proteins (RIPs) are endowed with several medicinal properties, including antiviral activity. We demonstrate here that the recently identified type I RIP from Momordica balsamina also possesses antiviral activity, as determined by ...

SARS-CoV-2 Mpro inhibitors with antiviral activity in a transgenic mouse model

Science, 2021
Targeting the SARS-CoV-2 main protease Vaccines are an important tool in the fight against COVID-19, but developing antiviral drugs is also a high priority, especially with the rise of variants that may partially evade vaccines.

The in vitro antiviral activity of lactoferrin against common human coronaviruses and SARS-CoV-2 is mediated by targeting the heparan sulfate co-receptor

Emerging Microbes and Infections, 2021
Coronavirus disease 2019 (COVID-19) is an ongoing pandemic that lacks effective therapeutic interventions. SARS-CoV-2 infects ACE2-expressing cells and gains cell entry through either direct plasma membrane fusion or endocytosis.

The vitamin D receptor agonist EB1089 can exert its antiviral activity independently of the vitamin D receptor.

PLoS ONE, 2023
Vitamin D has been shown to have antiviral activity in a number of different systems. However, few studies have investigated whether the antiviral activity is exerted through the vitamin D receptor (VDR).

Antiviral activity of bacterial TIR domains via immune signalling molecules

Nature, 2021
The Toll/interleukin-1 receptor (TIR) domain is a canonical component of animal and plant immune systems1,2. In plants, intracellular pathogen sensing by immune receptors triggers their TIR domains to generate a molecule that is a variant of cyclic ADP ...

Antiviral Activity of Silver, Copper Oxide and Zinc Oxide Nanoparticle Coatings against SARS-CoV-2

Nanomaterials, 2021
SARS-CoV-2 is responsible for several million deaths to date globally, and both fomite transmission from surfaces as well as airborne transmission from aerosols may be largely responsible for the spread of the virus.

MxA: a broadly acting effector of interferon-induced human innate immunity

Visualized Cancer Medicine, 2022
The Human MxA protein belongs to the dynamin superfamily of large GTPases and plays a vital role in human immunity against a broad spectrum of viruses. Evasion from MxA restriction accounts for the zoonotic transmission of many pathogenic viruses.

Antiviral activity of lambda-carrageenan against influenza viruses and severe acute respiratory syndrome coronavirus 2

Scientific Reports, 2021
Influenza virus and coronavirus, belonging to enveloped RNA viruses, are major causes of human respiratory diseases. The aim of this study was to investigate the broad spectrum antiviral activity of a naturally existing sulfated polysaccharide, lambda ...
