Figure 2.
Time courses of photoactivation of taxoid-tetrazole 1 (a) or 3 (b) monitored by UV-vis (dashed lines) and fluorescence (solid lines). Compounds were dissolved in acetonitrile/PBS (1:1) to derive concentrations of 25 µM, and the photoirradiation wavelength was set at 365 nm for 1 and 302 nm for 3. For fluorescence, λex = 405 nm.
