News: Antibiotic Properties of Phytocannabinoids in 2024

 

What's in the news?

       Antibiotic Properties of Phytocannabinoids, CSIR-IIIM Jammu researchers have found a compound, THCBD which has a potent antibiotic effect against Staphylococcus aureus bacterium.

 

Key takeaways:

       The CSIR-Indian Institute of Integrative Medicine (IIIM) in Jammu has conducted a study suggesting that certain compounds found in the cannabis plant, known as phytocannabinoids, may exhibit previously undiscovered antibiotic properties.

       Staphylococcus aureus is responsible for the second most number of deaths due to anti-microbial resistance.

 

Staphylococcus aureus:

       It is a gram-positive bacterium that causes a wide variety of clinical diseases.

       Examples - pneumonia, meningitis, osteomyelitis, endocarditis etc.

       It is found in the environment and is also found in normal human flora, located on the skin and mucous membranes (most often the nasal area) of most healthy individuals.

       Its transmission is mostly from direct contact.

 

THCBD's Antibacterial Properties:

       THCBD stands for tetrahydrocannabidiol (THCBD).

       It is a semisynthetic phytocannabinoid.

       Phytocannabinoid are cannabinoids that occur naturally in the cannabis plant.

 

Research Prospect:

       The researchers tested THCBD against bacterial cultures in the lab.

       It demonstrated strong effectiveness against efflux overexpression and MRSA strain.

       It has also reduced the number of viable microbial cells of S. aureus skin infections in mice.

       Hence, it can be a promising candidate to overcome anti-microbial resistance.

 

Go back to basics:

Antimicrobial Resistance:

       According to a senior principal scientist at the CSIR-National Chemical Laboratory (NCL), Pune, bacteria have developed certain sophisticated ‘shields’ over many decades to resist the effects of antibiotic medications.

       These include the formation of biofilms – thin sheets of bacterial colonies that are more resistant to antibiotics than when separated and cellular mechanisms called efflux pumps that flush drugs out from cells.

       The resulting AMR increases the risk of disease spread, severe illness, and death.

 

Cannabis Sativa:

       It is an herbaceous plant that belongs to the family Cannabinaceae.

       It has been used by humans for over 5,000 years for medicinal and recreational uses, firstly in Central and Northeast Asia and subsequently spreading worldwide.

       Cannabis, or marijuana, is undoubtedly one of the most widely used illicit drugs.

       It has a complex chemical composition that includes cannabinoids which are a group of secondary metabolites, several of which are responsible for the psychotropic effects.
