Paclitaxel (taxol) stabilizes microtubules in their polymerized form thus leading to cell death
Parthenolide is a sesquiterpene lactone and active principle of feverfew (Chrysanthemum parthenium)
Patulin: a cytostatic, antibacterial mycotoxin. Inhibits potassium uptake, activates the p38 kinase.
Paxilline: a selective blocker of high-conductance Ca2+-activated (Maxi-K) potassium channels
Penicillic acid is a polyketide mycotoxin which induces single and double strand DNA breaks. It inhibits GDP-mannose dehydrogenase.
Penitrem A, also known as Tremortin-A , is a tremorgenic toxin, potent inhibitor of smooth muscle high-conductance calcium-activated potassium channels.
Cyclic hexapeptide antibiotic. Phomopsin A exhibits very strong inhibitory properties of microtubule assembly. It binds to tubulin at a site different from the colchicine binding site.
PKC412 (Midostaurin) is a cell permeable inhibitor of protein kinases, including protein kinase-C.
Puromycin Aminonucleoside is a puromycin analog which does not inhibit protein synthesis or induce apoptosis
Puromycin is a protein synthesis inhibitor. It causes premature chain termination.
PX-866 is a synthetic derivate of wortmannin.
