Den naturliga produkten pironetin är känd för att binda till a-tubulin och är en potent inhibitor av mikrotubulepolymerisation. Tidigare rapporter hade identifierat 

2016-07-01 · Microtubule inhibitors have been shown to inhibit Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) signal transduction pathway in various cancer cells. However, little is known of the mechanism by which the microtubule inhibitors inhibit STAT3 activity.

We recently discovered a novel microtubule inhibitor, MPT0B098, that employs a novel antitumor mechanism. It destabilizes hypoxia-inducible factor (HIF)-1α mRNA by blocking the function of human antigen R. Thus, we proposed that MPT0B098 modulates hypoxia-induced EMT. Methods 2008-03-15 · Vinflunine: a new microtubule inhibitor agent. Bennouna J(1), Delord JP, Campone M, Nguyen L. Author information: (1)Centre René Gauducheau, Saint-Herblain, France. j-bennouna@nantes.fnclcc.fr Vinflunine (Javlor) is the first fluorinated microtubule inhibitor belonging to the Vinca alkaloids family. Microtubule inhibitors are used to treat ovarian cancer, breast cancer, lung cancer, kaposi's sarcoma, and prostate cancer.

They decrease the microtubule polymer mass in the cells at high concentration and act as microtubule-destabilizing agents. A mitotic inhibitor is a drug that inhibits mitosis, or cell division. These drugs disrupt microtubules, which are structures that pull the chromosomes apart when a cell divides. The microtubule inhibitors are a class of compounds that inhibit the function of cellular microtubules. The microtubules are key structural elements of the cell cytoskeleton composed of polymers of tubulin.

Microtubule inhibitors Use this guide to select the optimal compounds to target microtubules and key microtubule-associating proteins.

MMAF (Monomethylauristatin F) is applied as a cytotoxic component of antibody-drug conjugates (ADCs) such as vorsetuzumab mafodotin, ABT-414 and SGN-CD19A. Purity & Quality Control Choose Selective Microtubule Associated Inhibitors A microtubule inhibitor, ABT-751, induces autophagy and delays apoptosis in Huh-7 cells Paclitaxel, a microtubule inhibitor, is subject to tumor resistance while treating high-grade serous ovarian and uterine cancer. This study aims to directly compare the effects of SQ1274, a novel microtubule inhibitor that binds to the colchicine-binding site on tubulin, and paclitaxel in high-grade serous ovarian and uterine cancer cell lines both in vitro and in vivo .

Resistance to such microtubule inhibitors is complex and likely involves both pharmacokinetic (PK) effects and down-regulation of apoptosis pathways. The best-characterized resistance mechanism in cell culture is increased drug efflux mediated by the multidrug resistance protein 1 (MDR1), also known as P-glycoprotein, although the clinical relevance of this mechanism has yet to be firmly Thus, exogenous auxin induces transverse microtubule patterning through the TRANSPORT INHIBITOR 1/AUXIN F-BOX (TIR1/AFB) transcriptional pathway and can act independently of brassinosteroids. Application of auxin to light-grown seedlings elicits both axial growth and transverse patterning of the cortical microtubule cytoskeleton in hypocotyl cells. Because a role for microtubule inhibitors in the selective regulation of r(CUG)EXP levels had not been described, we further evaluated microtubule inhibition in multiple DM1 models. We primarily focused on colchicine because it is an inexpensive, FDA-approved, natural therapeutic that is generally well-tolerated and is currently used in the clinic to treat gout and familial Mediterranean fever Our results delineate a distinct molecular mechanism of action for the inhibition of microtubule assembly by clinically relevant agents.
