, (2015/12/09)
The present disclosure relates to a therapeutic agent of the formula: Z-C(=O)-(CH2)n-?-S-S-(CRR')m-(CH2)p-C(=O)- NH-(CH2)q-NH-Y[NH-(CH2)r-X-T-W][NH-(CH2-CH-O)t (CH2)s-NH-V] Formula I or a pharmaceutically acceptable salt thereof, useful for treating tumors, including cancers. Where the compound of Formula I also contains a radionuclide or an imaging agent or both, the compound of formula I is a theranostic agent useful for treating and diagnosing tumors, including cancers.

Novel tumor-targeting dual-warhead conjugates, 2 (DW-1) and 3 (DW-2), which consist of a next-generation taxoid, 1 (SB-T-1214), and camptothecin as two warheads, self-immolative disulfide linkers for drug release, biotin as the tumor-targeting moiety, and 1,3,5-triazine as the tripod splitter module, were designed and synthesized. The potency of 2 was evaluated against MX-1, MCF-7, ID8, L1210FR (BR+, biotin receptor overexpressed) and WI38 (BR-, normal) cell lines in the absence and presence of glutathione (GSH), which is an endogenous thiol that triggers drug release inside the cancer cells. With the GSH and resuspension protocol, 2 exhibited IC50 values of 3.22-9.80 nM against all BR+ cancer cell lines, and 705 nM against WI38. Thus, there was a two orders of magnitude higher selectivity to cancer cells. Also, a clear cooperative effect was observed for the taxoid-camptothecin combination when two drugs were delivered to the cancer cells specifically in the form of a dual-warhead conjugate.
