The latrunculins are a family of natural products and toxins produced by certain sponges, including genus Latrunculia and Negombata, whence the name is derived. It binds actin monomers near the nucleotide binding cleft with 1:1 stoichiometry and prevents them from polymerizing. Administered in vivo, this effect results in disruption of the actin filaments of the cytoskeleton, and allows visualization of the corresponding changes made to the cellular processes. This property is similar to that of cytochalasin, but has a narrow effective concentration range. Latrunculin has been used to great ef

In chemistry, thiadiazoles are a sub-family of azole compounds, with the name thiadiazole originating from the Hantzsch–Widman nomenclature. Structurally, they are five-membered heterocyclic compounds containing one sulfur and two nitrogen atoms. The ring is aromatic by virtue of the two double bonds and one of the lone pairs of electrons of sulfur. Four constitutional isomers are possible, differing by the relative positions of the sulfur and nitrogen atoms. The nomenclature thus includes the locations of each of those three atoms, with the first of the three numbers referring to the sulfur.
