It disrupts formation of the mitotic spindle and triggers the caspase-dependent apoptotic pathway, and it retains inhibitory activity against Paclitaxel-sensitive cell lines while overcoming drug resistance; it can be used to study Paclitaxel\/Docetaxel-resistant solid tumors\u003csup\u003e[1]\u003c\/sup\u003e. Its molecular formula is C46H57NO15S, with a molecular weight of 896.01 g\/mol.\u003c\/p\u003e\n\u003ch2\u003ePhysical \u0026amp; Chemical Properties\u003c\/h2\u003e\n\u003ctable class=\"bhp-spec-table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eCAS Number\u003c\/th\u003e\n\u003ctd\u003e791635-59-1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMolecular Formula\u003c\/th\u003e\n\u003ctd\u003eC46H57NO15S\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMolecular Weight\u003c\/th\u003e\n\u003ctd\u003e896.01 g\/mol\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSMILES\u003c\/th\u003e\n\u003ctd\u003eO[C@H]1C[C@]2([H])[C@](CO2)(OC(C)=O)[C@]3([H])[C@@]1(C([C@H](OC(C4CCCC4)=O)C5=C(C)[C@@H](OC([C@H](O)[C@@H](NC(OC(C)C)=O)C6=CC=CS6)=O)C[C@]([C@H]3OC(C7=CC=CC=C7)=O)(O)C5(C)C)=O)C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSignaling Pathway\u003c\/th\u003e\n\u003ctd\u003eCell Cycle\/DNA Damage; Cytoskeleton; Apoptosis\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStorage\u003c\/th\u003e\n\u003ctd\u003ePlease store the product under the recommended conditions in the Certificate of Analysis.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShipping\u003c\/th\u003e\n\u003ctd\u003eRoom temperature in continental US; may vary elsewhere.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch2\u003eLiterature Cited\u003c\/h2\u003e\n\u003cp style=\"font-size:14px;color:#555;margin:0 0 10px\"\u003e\u003cem\u003eSources cited in this description.
