WebConsequently, Bortezomib counteracts Taxol-induced mitotic arrest and polyploidy, as shown by reduced expression of PLK1 and phosphorylated histone H3. In addition, Bortezomib antagonizes Taxol-mediated degradation of MCL-1 during mitotic arrest by preventing cells to enter mitosis and by inhibiting the proteasome. WebTaxol total synthesis in organic chemistry is a major ongoing research effort in the total synthesis of Taxol.This diterpenoid is an important drug in the treatment of cancer but also expensive because the compound is harvested from a scarce resource, namely the pacific yew.Not only is the synthetic reproduction of the compound itself of great commercial …
WebWe are mainly focusing on isoprenoids (e.g. anti-cancer drug Taxol), chiral amino-alcohols and venturing in marine natural products and antibodies. We have developed efficient ways to insert selected genes and pathways in different host cells in such a way that the pathways could be sequentially built and optimised. WebAbstract. Formal total synthesis of (−)-taxol is described herein. This convergent synthesis was accomplished by utilizing two chiral fragments, both of which were prepared via asymmetric catalysis. A palladium-catalyzed reaction was found to afford the eight-membered ring effectively, i.e ., a B -alkyl Suzuki-Miyaura coupling reaction and an ...
