When Grifulvin is ingested, it gets absorbed into the bloodstream and reaches the site of the fungal infection.
Inside fungal cells, griseofulvin binds to tubulin, disrupting the formation of microtubules, which are essential for the fungal cell’s structure and function.
This disruption inhibits the fungal cell from dividing and replicating, eventually leading to the suppression of fungal growth.
Key Points:
- Griseofulvin targets fungal cells by binding to tubulin.
- It disrupts the formation of microtubules in fungal cells.
- This disruption inhibits fungal cell division and replication.
- Ultimately, it suppresses fungal growth.
According to NCBI, tubulin is a crucial protein involved in the assembly of microtubules, which are necessary for the structural integrity and function of fungal cells. By binding to tubulin, griseofulvin interferes with the proper assembly of microtubules.
This interference leads to defects in mitosis and cell division in fungal cells. Without the ability to divide and replicate properly, the fungal cells are unable to grow and spread, resulting in the inhibition of fungal growth.
It is important to note that the mechanism of action of griseofulvin is specific to fungal cells and does not affect human cells. This selectivity makes Grifulvin a safe treatment option for fungal infections.
