Dynasore hydrate is widely used in biological and pharmacological research due to its ability to inhibit dynamin, a protein involved in endocytosis. It is particularly valuable in studying cellular processes such as membrane trafficking, vesicle formation, and receptor internalization. Researchers utilize it to explore the mechanisms of viral entry into cells, as many viruses rely on endocytosis for infection. Additionally, it is employed in neuroscience to investigate synaptic vesicle recycling and neurotransmitter release. Its role in inhibiting dynamin also makes it a useful tool in cancer research, where it helps in understanding the regulation of cell signaling and proliferation pathways.
