- Affinity-Driven Covalent Modulator of the Glyceraldehyde-3-Phosphate Dehydrogenase (GAPDH) Cascade
-
Traditional medicines provide a fertile ground to explore potent lead compounds, yet their transformation into modern drugs is fraught with challenges in deciphering the target that is mechanistically valid for its biological activity. Herein we reveal that (Z)-(+)-isochaihulactone (1) exhibited significant inhibition against multiple-drug-resistant (MDR) cancer cell lines and mice xenografts. NMR spectroscopy showed that 1 resisted an off-target thiolate, thus indicating that 1 was a target covalent inhibitor (TCI). By identifying the pharmacophore of 1 (α,β-unsaturated moiety), a probe derived from 1 was designed and synthesized for TCI-oriented activity-based proteome profiling. By MS/MS and computer-guided molecular biology approaches, an affinity-driven Michael addition of the noncatalytic C247 residue of GAPDH was found to control the “ON/OFF” switch of apoptosis through non-canonically nuclear GAPDH translocation, which bypasses the common apoptosis-resistant route of MDR cancers.

- Synthesis and structure-activity relationships of nitrobenzyl phosphoramide mustards as nitroreductase-activated prodrugs
-
A series of nitrobenzyl phosphoramide mustards and their analogs was designed and synthesized to explore their structure-activity relationships as substrates of nitroreductases from Escherichia coli and trypanosomes and as potential antiproliferative and antiparasitic agents. The position of the nitro group on the phenyl ring was important with the 4-nitrobenzyl phosphoramide mustard (1) offering the best combination of enzyme activity and antiproliferative effect against both mammalian and trypanosomatid cells. A preference was observed for halogen substitutions ortho to benzyl phosphoramide mustard but distinct differences were found in their SAR of substituted 4-nitrobenzyl phosphoramide mustards in E. coli nitroreductase-expressing cells and in trypanosomatids expressing endogenous nitroreductases.

- Substituent effects on the kinetics of reductively-initiated fragmentation of nitrobenzyl carbamates designed as triggers for bioreductive prodrugs
-
4-Nitrobenzyl carbamates are of interest as triggers for bioreductive drugs, particularly in conjunction with the E. coli B nitroreductase, which efficiently reduces them to the corresponding hydroxylamines. These then fragment to release highly toxic amine-based toxins. While many 4-nitrobenzyl carbamate derivatives have been evaluated as bioreductive drugs, there has been no systematic study of substituent effects on the rate of this fragmentation (which should be as fast as possible following reduction). We therefore prepared a series of 2-, 3- and α-substituted 4-[N-methyl-N-(4-nitrobenzyloxycarbonyl)amino]phenylacetamides as model compounds to study these effects. The majority of the carbamates were prepared by in situ formation of the chloroformate of the appropriate 4-nitrobenzyl alcohol and reaction with methyl 4-(methylamino)phenylacetate, followed by ester hydrolysis and 1,1′-carbonyl-diimidazole (CDI) mediated coupling with N,N-dimethylaminoethylamine. The hydroxylamines were generated by 60Co γ-ray irradiation of the nitro compounds in aqueous phosphate-buffered-propan-2-ol. The reactions were analysed by reverse-phase HPLC to determine the maximum half-life (Mt1/2) of the hydroxylamines generated, and the extent of release of amine from these after 10 half-lives (t∞). The parent (unsubstituted) hydroxylaminobenzyl carbamate had a Mt1/2 of 16 min under these conditions, while that of the corresponding α-methyl analogue was 9.5 min. Electron-donating substituents on the benzyl ring also accelerated fragmentation, with the data being fitted to the equation log(Mt1/2) = 0.57σ + 1.30, where σ represents σp for 2-substituents and σm for 3-substituents. The acceleration of fragmentation of the hydroxylamines with increasing substituent electron-donation is consistent with the proposed mechanism, and is presumably due to stabilisation of the developing positive charge on the benzylic carbon. The extent of release of amine (t∞) also increased with increasing substituent electron-donation. These data suggest that the standard 4-nitrobenzyl carbamate trigger for nitroreductase enzyme (NTR) prodrugs can likely be improved on, by increasing the rate of fragmentation by the use of α-methyl and/or electron-donating benzyl substituents.
