AB  - Sdox is a hydrogen sulfide (H2S)-releasing doxorubicin effective in P-glycoprotein-overexpressing/doxorubicin-resistant tumor models and not cytotoxic, as the parental drug, in H9c2 cardiomyocytes. The aim of this study was the assessment of Sdox drug-like features and its absorption, distribution, metabolism, and excretion (ADME)/toxicity properties, by a multi- and transdisciplinary in silico, in vitro, and in vivo approach. Doxorubicin was used as the reference compound. The in silico profiling suggested that Sdox possesses higher lipophilicity and lower solubility compared to doxorubicin, and the off-targets prediction revealed relevant differences between Dox and Sdox towards several cancer targets, suggesting different toxicological profiles. In vitro data showed that Sdox is a substrate with lower affinity for P-glycoprotein, less hepatotoxic, and causes less oxidative damage than doxorubicin. Both anthracyclines inhibited CYP3A4, but not hERG currents. Unlike doxorubicin, the percentage of zebrafish live embryos at 72 hpf was not affected by Sdox treatment. In conclusion, these findings demonstrate that Sdox displays a more favorable drug-like ADME/toxicity profile than doxorubicin, different selectivity towards cancer targets, along with a greater preclinical efficacy in resistant tumors. Therefore, Sdox represents a prototype of innovative anthracyclines, worthy of further investigations in clinical settings.

AB  - Microtubule targeting agents (MTAs) are extensively used in cancer treatment and many have achieved substantial clinical success. In recent years, targeting microtubules to inhibit cell division has become a widespread pharmaceutical approach for treatment of various cancer types. Nevertheless, the development of multidrug resistance (MDR) in cancer remains a major obstacle for successful application of these agents. Herein, we provided the evidence that CKT0353, α-branched α,β-unsaturated ketone, possesses the capacity to successfully evade the MDR phenotype as an MTA. CKT0353 induced G2/M phase arrest, delayed cell division via spindle assembly checkpoint activation, disrupted the mitotic spindle formation and depolymerized microtubules in human breast, cervix, and colorectal carcinoma cells. Molecular docking analysis revealed that CKT0353 binds at the nocodazole binding domain of β-tubulin. Furthermore, CKT0353 triggered apoptosis via caspase-dependent mechanism. In addition, P-glycoprotein overexpressing colorectal carcinoma cells showed higher sensitivity to this agent when compared to their sensitive counterpart, demonstrating the ability of CKT0353 to overcome this classic MDR mechanism involved in resistance to various MTAs. Taken together, these findings suggest that CKT0353 is an excellent candidate for further optimization as a therapeutic agent against tumors with MDR phenotype.

AB  - The efficacy of microtubule targeting agents in cancer treatment has been compromised by the development of drug resistance that may involve both, P-glycoprotein overexpression and the changes in β-tubulin isoforms' expression. The anti-Topoisomerase II activity of methyl 4-((E)-2-(methoxycarbonyl)vinyloxy)oct-2-ynoate (DTA0100) was recently reported. Herein, we further evaluated this propargylic enol ether derivative and found that it exerts inhibitory effect on tubulin polymerization by binding to colchicine binding site. DTA0100 mitotic arrest properties were investigated in two multi-drug resistant cancer cell lines with P-glycoprotein overexpression (colorectal carcinoma and glioblastoma). The sensitivity of multi-drug resistant cancer cell lines to DTA0100 was not significantly changed in contrast to microtubule targeting agents such as paclitaxel, vinblastine and colchicine. DTA0100 clearly induced microtubule depolymerization, leading to disturbance of cell cycle kinetics and subsequent apoptosis. The fine-tuning in β-tubulin isoforms expression observed in multi-drug resistant cancer cells may influence the efficacy of DTA0100. Importantly, DTA0100 blocked the P-glycoprotein function in both multi-drug resistant cancer cell lines without inducing the increase in P-glycoprotein expression. Therefore, DTA0100 acting as dual inhibitor of Topoisomerase II and microtubule formation could be considered as multi-potent anticancer agent. Besides, it is able to overcome the problem of drug resistance that emerges in the therapeutic approaches with either Topoisomerase II or microtubule targeting agents.
