Challenge Mission

COVID Problem We Address

Effective treatment for Covid is producted by our product. Both biosilver and Cepharanthine are known ingredients with well documented studies on the efficacy against virus in vitro as well as having a good safety profile. Our product can be either a standalone medicine or can be included in the prescription list for Covid patients along with regular drugs to reduce viral load. 

Our COVID Solution

Our product is precisely engineered to target corona virus membrane. Silver binds to gylcoprotien in virus envelope and CEP also interacts with gylcoprotiens and stops virus from replicating. This double attack strategy of focussing on a common point of gylcoprotiens by both the ingredient of our product may result in better disruption of the viral membrane as compared to current market products. Additionally CEP is also anti-inflamatory which will reduce the cytokine releases.

BioSilver Nanoparticles Loaded with CEP


Introduction to Cepharantine (CEP):

Reference : 1


Cepharanthine (CEP) is a naturally occurring alkaloid derived from Stephania cepharantha and

have unique anti-inflammatory, antioxidative, immunomodulating, antiparasitic, and antiviral

properties. Its therapeutic potential as an antiviral agent has never been more important in

combating COVID-19 caused by severe acute respiratory syndrome coronavirus type 2 (SARSCoV-2) virus and resulting so far in over four million cases since its onset.



Mechanism of action of CEP:

Reference : 2


Cepharanthine suppresses nuclear factor-kappa B (NF-κB) activation, lipid peroxidation, nitric

oxide (NO) production, cytokine production, and expression of cyclooxygenase; all of which are

crucial to viral replication and inflammatory response. Against SARS-CoV-2 and homologous

viruses, CEP predominantly inhibits viral entry and replication at low doses; and was recently

identified as the most potent coronavirus inhibitor among 2,406 clinically approved drug

repurposing candidates in a preclinical model. This analyzes and consolidates available evidence

establishing CEP’s potential therapeutic importance as a drug of choice in managing COVID-19

cases. So far, encouraging preclinical evidence about CEP’s safety profile, wide availability, and

unique antiviral properties especially against specific beta-coronaviruses supports its use as a drug

of choice in the treatment of human coronavirus diseases. However, further in vivo testing and

clinical trials are urgently required to provide additional data supporting the development of CEP

into antiviral medications, spurred by its superior antiviral and antiinflammatory activities in

preclinical settings relative to established antiviral agents. The ability of CEP to disable the

attachment and entry of SARS-CoV-2 into target cells demonstrates its great therapeutic potential

as a drug to combat COVID-19. Also, its low EC50 and CC50 achievable with oral dosing, and

synergistic properties when combined with other antiviral medications (such as nelfinavir 9 and

mefloquine), further supports its excellent pharmacokinetic profile and establishes its importance

in the fight against COVID-19.



CEP binding to gycloprotien at viral entry and postentry viral replication.

Reference – 3


CEP binds to gylcoprotien and prevents it from engaging with viral receptor. Cepharanthine

prevents the virus from attaching to and entering cells. The CEP molecule binds to the spike

glycoprotein of the virus and prevents it from engaging with the viral receptor. This is the

angiotensin-converting enzyme 2 (ACE2).

CEP is useful against Corona Screening drug studies on pangolin SARS-CoV-2, which is the human-related Coronavirus, demonstrated that three drugs (cepharanthine, selamectin and mefloquine hydrochloride) were effective in inhibiting viral replication, with cepharanthine potently inhibiting coronavirus infection



Silver Binding to gylcoprotien

Reference : 4


Silver binds to viral gylcoprotien and same stands true in case of similar virus like Corona. Recent

studies have identified the broad-spectrum antiviral properties of silver nanoparticles (AgNPs)

against respiratory pathogens, such as adenovirus, parainfluenza, and influenza. AgNPs achieve

this by attaching to viral glycoproteins, blocking entry into the host cell. Silver binds to viral

gylcoprotien is concluded in the study. The regular spatial arrangement of the attached

nanoparticles, the center-to-center distance between nanoparticles, and the fact that the exposed

sulfur-bearing residues of the glycoprotein knobs. would be attractive sites for nanoparticle

interaction suggest that silver nanoparticles interact with the HIV-1 virus via preferential binding

to the gp120 glycoprotein knobs. Due to this interaction, silver nanoparticles inhibit the virus from

binding to host cells, as demonstrated in vitro.




Nanoparticles in treatment:


Researchers have been investigating the potential of using nanoparticles to treat bacterial and viral

infections for years now. The idea of using nanoparticles, is that the SARS-CoV-2, which is the

virus behind COVID-19 consists of a structure of a similar scale asnanoparticles. Gold

nanoparticles, for example, are made to attach to viruses such as Ebola or influenza and by heating

the particles with certain infrared wavelengths, the nanoparticles can then destroy the structure of

the virus. Nanoparticles can be used to deliver drugs as well. Silver on the other hand, has been

the most extensively studied metal for purpose of fighting infections and preventing food spoilage,

and notwithstanding the decline of its use as a consequence of the development of antibiotics,

prophylaxis against gonococcal ophthalmia neonatorum with silver ions was considered the

standard of care in many countries until the end of the 20th century.Antibacterial, antifungal and

antiviral properties of silver ions and silver compounds have been extensively studied. Silver has

also been found to be non-toxic to humans at very small concentrations. The microorganisms are

unlikely to develop resistance against silver as compared to antibiotics as silver attacks a broad

range of targets in the microbes.The antimicrobialproperties of silver nanoparticles are well

established and is medically FDA approved in field of woundcare. Bio-silver nanoparticles are

chemically inert and does not contain any side effects associated with the chemically synthesized

silver nanoparticles and are non-toxic. The goal of this product is to substantiate potential

antimicrobial bio-silverformulation to deliver plant-derived antiviral alkaloid (Cepharanthine

(CEP)) by inhalation, to minimise the aggravation of respiratory system infections caused by

SARS-CoV-2. This product aims at the major contribution that nanotechnology solutions can bring

to mitigate the acute and chronic effects of COVID-19 pandemic from the protection and

medication point of view by potentially blocking viral replication of SARS-CoV-2. This product

containing silver nanoparticles with the size in the range of less than 100 nm and coated with

polyethylene glycol (PEG) can be deliver in the form of dry powder inhaler via oral inhalation in

the form of single use capsules or multidose inhalers such as sunhaler or Advair diskus. We

proclaim that for significant antiviral effectiveness the size of silver nanoparticlesneeds to be less

than 100nm, preferably in the range 30nm-70nm size. The PEG coating on the silver nanoparticles

will ensure there is minimal clearance of nanoparticles in the spleen and liver by macrophages and

Kupffer cells.




Animal Studies:

Reference : 5


Biologically synthesized AgNPs with an average size of 60 nm with concentrations of 15 and 20 mg/kg of AgNPs-loaded vaccine injected into the mice and dogs. The in vivo toxicity also elucidated the safety of AgNPs and AgNPs-loaded vaccine in mice and dogs, respectively. Safety test for veterinary use was carried out on two healthy female dogs. After administration of AgNPs-loaded rabies vaccines, the animals were daily monitored for 14 days. The animals did not show signs of either disease or local and systemic reactions and no fever or death was observed due to the vaccine during monitoring. The study shows that AgNPs can be used as adjuvant in rabies veterinary vaccine. AgNPs interact with the virion surface as well with the virion core Peste des petits ruminants virus and it shows that there is no significant effect on the virucidal effect, instead it exerts a blocking effect on viral entry into the target cells. The antiviral activity of tannic acid modified various sizes of AgNPs was studied. The study concluded that it required direct interaction and blocked virus attachment, penetration, and further spread.


bioSilver nanoparticles in Ayurveda:

Reference : 6


Silver has been processed using herbal extracts as reducing agent to form bhasma in Ayurveda. There is a history of consumption of this preparation in India. Currently there are several type of biometallic nanoparticles being used in Ayurvedic medicines in India approved by regulator. There has no report of adverse cases caused by consumption of bhasmas. Scientific analysis on Rajat bhasma showed that Silver nanoparticles was spherical in the range of 5–50 nm and uniformly distributed without significant agglomeration. This proves silver bhasma used in Ayurveda are nanoparticles and widely used since ancient times.
