TM-2 (13-(N-Boc-3-i-butylisoserinoyl-4,10-β-diacetoxy-2-α-benzoyloxy-5-β-20-epoxy-1,13-α-dihydroxy-9-oxo-19-norcyclopropa[g]tax-11-ene) is a novel semisynthetic taxane derivative. Our previous study suggested that TM-2 is a promising antitumor analogue. In this paper, the metabolism of TM-2 was investigated in rats following intravenous administration. Two(More)
RATIONALE TM-2 (13-(N-Boc-3-i-butylisoserinoyl-4,10-β-diacetoxy-2-α-benzoyloxy-5-β,20-epoxy-1,13-α-dihydroxy-9-oxo-19-norcyclopropa[g]tax-11-ene) is a novel semi-synthetic taxane derivative. Our previous study demonstrated that it is a promising taxane derivative. The in vitro comparative metabolic profile of a drug between animals and humans is a key issue(More)
TM-2 is a novel semi-synthetic taxane derivative, selected for preclinical development based on its greater anticancer activity and lower toxicity compared with docetaxel. In this study, a rapid and sensitive analytical method based on ultra performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) has been developed for the determination of(More)
A simple and sensitive method based on ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) has been developed for the determination of TM-2, which was a novel semi-synthetic taxane derivative in beagle dog plasma. Cabazitaxel was chosen as internal standard. Following extraction by methyl tert-butyl ether, the chromatographic(More)
A new benzoic acid, 2-(2-hydroxypropanamido) benzoic acid (1), along with three known compounds, cyclo-(Pro-Leu), cyclo-(4-hydroxyl-Pro-Phe), and (22E,24R)-ergosta-5,7,22-triene-3β-ol, were isolated from the fermentation broth of Penicillium chrysogenum. The structure of compound 1 was established by comprehensive analysis of the spectral data, especially(More)
A simple, specific, and sensitive ultra high performance liquid chromatography with tandem mass spectrometry method was developed and validated for the simultaneous quantification of nine compounds including a new compound, rhamnazin-3-Ο-β-D-(6″-β-hydroxy-β-methyglutaryl)-β-D-glucoside-4'-Ο-β-D-glucoside, in rat plasma using baicalin as an internal(More)
In order to investigate the pharmacokinetics of triamcinolone acetonide palmitate (TAP) which is a lipid-soluble prodrug of triamcinolone acetonide (TA), a rapid, simple, sensitive and reproducible UPLC-MS/MS method has been developed and validated for the simultaneous determination of TAP and TA in beagle dog plasma. After simple liquid-liquid extraction,(More)
1. TM-2 is a promising novel semi-synthetic taxane derivative with greater antitumor activity especially against resistant tumors and lower toxicity compared with docetaxel. Information on distribution and excretion of the pharmaceutical in animals, as well as biochemical information relevant to potential drug interactions should normally be evaluated prior(More)
