生物活性

Mycalolide-B is a specific inhibitor of actomyosin ATPase isolated from marine sponge. Mycalolide-B inhibits ATP-induced contraction and Mg2+-ATPase activity in the absence of Ca2+[1].

IC50 & Target

actomyosin ATPase[1]

体外研究
(In Vitro)

Mycalolide-B belongs to macrolide antibiotics and consists of tris-oxazole with strong cytotoxic activity (IC50: 10-50 nM for growth of L1210 murine leukemia cells). Mycalolide-B, a toxin isolated from marine sponge, inhibits smooth muscle contractions without changing cytosolic Ca2+ levels. Mycalolide-B also inhibits Ca2+-induced contraction in permeabilized smooth muscles. Mycalolide-B inhibits superprecipitation and Mg2+-ATPase activity stimulated by Ca2+ without changing myosin light chain phosphorylation. Mycalolide-B inhibits ATP-induced contraction and Mg2+-ATPase activity in the absence of Ca2+[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
