La pironetina es una lactona insaturada α/β aislada de especies de Streptomyces. La pironetina se une a la α-tubulina y es un potente inhibidor de la polimerizaciÓn de los microtÚbulos, y tiene actividad antitumoral y de detenciÓn del ciclo celular.

Pironetin is an α/β unsaturated lactone isolated from Streptomyces species. Pironetin binds to α-tubulin and is a potent inhibitor of microtubule polymerization, and has cell cycle arrest and antitumor activity[1][2].
Pironetin (20-100 ng/mL; 24 hours; 3Y1 cells) treatment arrests the cell cycle progression at G2/M in 3Y1 cells[1].Pironetin (1-10000 ng/mL; 3 days; HeLa, A2780 and K-NRK cells) treatment inhibits the cell proliferation. IC50 values against these cell lines are almost 10 ng/mL[1]. Cell Cycle Analysis[1] Cell Line: 3Y1 cells
Pironetin (0.78-6.25 mg/kg; intraperitoneal injection; daily; for 5 days; female CDF1-SLC mice) treatment shows a moderate antitumor effect, however, a severe weight loss is observed as a side effect[1]. Animal Model: Female CDF1-SLC mice (10 weeks) injected with P388 murine leukemia cells[1]
