Latest Patents

Samaranyake's latest patents focus on rearranged taxol compounds and methods for using them in testing of in vivo. In a preferred embodiment, taxol is treated with mesyl chloride to prepare a taxol derivative with a contracted A-ring. This derivative exhibits comparable activity to taxol in a tubulin depolymerization assay and shows cytotoxicity against KB cells in a cell culture assay. In an alternate preferred embodiment, taxol is treated with triethyloxonium tetrafluoroborate, also known as Meerwein's reagent, to produce a taxol derivative with an opened oxetane ring. Additionally, another preferred embodiment involves the reaction of taxol with acetyl chloride, yielding a taxol derivative where the oxetane ring is opened and the A-ring is contracted. All of these products demonstrate in vivo activity in KB cell culture assays. The preferred compounds have varying in vivo activities, making them ideal for forming a range of standards for biological testing of other compounds.
