Conformational Studies of Paclitaxel Analogs Modified at the C-2‘ Position in Hydrophobic and Hydrophilic Solvent Systems
摘要:
The conformations of two paclitaxel analogs modified at the C-2' position, 2'-deoxypaclitaxel and 2'-methoxypaclitaxel, were studied in hydrophobic Emd hydrophilic solvent systems by a combination of NMR spectroscopy, CD measurements, and molecular modeling. Both analogs have hydrophobic and hydrophilic conformations that resemble those of paclitaxel itself in the same media. Since the two have diminished biological activities in a number of bioactivity assays and the hydrogen-bonding capability of the 2'-hydroxyl group has been eliminated, we postulate that this group is involved in hydrogen bonding with tubulin and plays an important role in molecular recognition. The results of this study are in agreement with our earlier report on paclitaxel 2'-acetate, an analog in which the 2'-hydroxyl group hydrogen-bonding capacity has also been eliminated.

Disclosed are compounds for the selective labeling of cell-surface sugars in cancer cells. The compounds are activatable by triggers specific to cancer cells, and, when metabolized, label a cancer cell surface sugar with an azide chemical group. Facilitated by a click chemistry reaction, combination of the cell surface-expressed azide with a alkynyl- drug conjugate enables efficient targeted drug delivery to cancer cells with reduced toxicity Also disclosed are compounds for delivering a drug to an azide-bearing cancer cell, and methods of treating cancer using the compounds of the invention.

Disclosed are bis(thio-hydrazide amide) disalts, which are represented by Structural Formula (I)
2 M+ or M2+Y is a covalent bond or a substituted or unsubstituted straight chained hydrocarbyl group. R1-R4 are independently -H, an aliphatic group, a substituted aliphatic group, an aryl group or a substituted aryl group, or R1 and R3 taken together with the carbon and nitrogen atoms to which they are bonded, and/or R2 and R4 taken together with the carbon and nitrogen atoms to which they are bonded, form a non-aromatic heterocyclic ring optionally fused to an aromatic ring. Z is -O or -S. M+ is a pharmaceutically acceptable monovalent cation and M2+ is a pharmaceutically acceptable divalent cation. Also disclosed are pharmaceutical compositions comprising a bis(thio-hydrazide amide) disalt described above. Further disclosed are methods of treating a subject with cancer. The methods comprise the step of administering an effective amount of a bis(thio-hydrazide amide) disalt.
The present disclosure generally provides compounds useful for treating cancer. In some aspects, the disclosure provides small-molecule cytotoxins that are chemically modified to include one or more moieties that include hydrophobic portions. In some embodiments, the disclosure provides small-molecule cytotoxins that are chemically modified with fatty acid-containing moieties. In some aspects, the disclosure provides compositions, such as pharmaceutical compositions, that include such modified small-molecule cytotoxins and a protein. In some embodiments, the protein is albumin or an albumin mimetic. Further, the disclosure provides various uses of these compounds and compositions.
