Photoaffinity labeling methods are being used to define the molecular contacts between taxol and its target protein, tubulin. Our laboratory has demonstrated previously that [3H]3′-(p-azidobenzamido)taxol photolabels the N-terminal 31 amino acids o

4-Deacetoxypaclitaxel ( 9 ) has been prepared in seven steps from paclitaxel (Taxol ® ). It is significantly less active than paclitaxel in tubulin-assembly and cytotoxicity bioassays.

The 7-substituted taxol analogues 7, 19, 27, and 32 have been prepared as potential photoaffinity-labeled derivatives for studies of the nature of the binding site of taxol on polymerized tubulin. The analogue 32 has been prepared in both deuterium-

10-Deacetoxytaxol (9) and 10-deoxytaxotere (10) have been prepared from 10-deacetylbaccatin III by attachment of the C-13 side-chain and deoxygenation. 10-Deacetoxytaxol is comparable to taxol in its cytotoxicity to P-388 cells, but 10-deoxytaxotere
