    Abstract Medicinal value of natural products comes from symbiotic and competitive evolution in Earth's complex biosphere. Billions of years of co-evolutionary interactions among millions of species have produced a large repertoire of defense molecules effective in fighting bacteria, viral, and fungal pathogens. Each species contains millions of different and useful molecules and new research technologies enabled the screening of molecules and complex mixtures from diverse biological sources. Traditional use of plants and other species led to the discovery of many bioactive compounds with various properties. In the last four decades, a large number of them were evaluated for their potential to treat cancer. Penetration of drugs into the cancer cell is necessary for their lethal pharmacological effect through interaction with intracellular target molecules. Increased activity of membrane efflux pumps reduces the intracellular drug accumulation, thereby preventing drug-target interactions. The discovery of the efflux transporter P-glycoprotein (P-gp) in multidrug resistant (MDR) cancer cells prompted the efforts in overcoming drug resistance by P-gp inhibition. The search for nontoxic anticancer agents from natural sources able to overcome MDR has been imperative in the field of drug design and discovery. Herein, we review various natural compounds from diverse sources emphasizing their potential to inhibit P-gp activity and/or expression.

    Abstract Species of the mite genus Protzia Piersig, 1896 are diverse and sometimes highly abundant freshwater mites. Here, we provide COI barcodes for five species (Protzia rugosa, P. rotunda, P. halberti, P. cabardinica, P. longiacetabulata) and use them for species delimitation analyses accompanied with morphological comparisons. As a result, we resurrected the species P. cabardinica (Sokolow, 1940). Based on morphology only, we describe three new species, P. kyrgyzicasp. nov. and P. tienshanensissp. nov., from Kyrgyzstan and P. iranicasp. nov. from southern Iran. Furthermore, we describe the male of P. longiacetabulata from Turkey, which was not known previously.

    Abstract The number of multidrug resistant (MDR) cancer cases across the globe is continuing to rise, such that the search for novel anti-cancer therapeutics is paramount. For instance, the overexpression of membrane transport proteins, such as P-glycoprotein (P-gp), or the selective modulation of protein kinases C (PKC) isoforms continues to be a major impediment to effective therapy. Known for their medicinal properties, species from Plectranthus have been reported to have cytotoxicity against various cancer cell lines due to diterpenes, such as 7α-acetoxy-6β-hydroxyroyleanone ( Roy ) and 6,7-dehydroroyleanone ( DeRoy ). Based on molecular docking simulations, 10 semi-synthetic derivatives of Roy that displayed strong P-gp interactions in silico were prepared. The antitumoral activity was evaluated in resistant human cancer cell lines NCI-H460/R and DLD1-TxR, showing three derivatives having the most prominent selectivity towards cancer cells, compared to normal lung fibroblasts MRC5. Moreover, they showed a reduction in P-gp activity in Rho123 accumulation and indicated P-gp inhibition in the DOX accumulation assay using the same resistant cell lines. Overall, it was demonstrated that three abietane diterpenoids induced P-gp inhibition in MDR cancer cell lines. As regards the PKC activity, further analogues were tested as PKC (α, βI, δ, ε and ζ) modulators; one benzoylated derivative showed the ability to selectively activate PKC-δ, while the natural compound DeRoy displayed improved PKC activity, compared with the positive control, in all tested isoforms. Further investigations are ongoing to prepare analogues of other biologically active diterpenoids to obtain potential hits as P-gp and PKC modulators.

    Abstract Albicidin is a potent DNA gyrase inhibitor produced by the sugarcane pathogenic bacterium Xanthomonas albilineans. Here we report the elucidation of the hitherto unknown structure of albicidin, revealing a unique polyaromatic oligopeptide mainly composed of p-aminobenzoic acids. In vitro studies provide further insights into the biosynthetic machinery of albicidin. These findings will enable structural investigations on the inhibition mechanism of albicidin and its assessment as a highly effective antibacterial drug.

    Abstract Heat Shock Protein 90 (Hsp90) chaperone interacts with a broad range of client proteins involved in cancerogenesis and cancer progression. However, Hsp90 inhibitors were unsuccessful as anticancer agents due to their high toxicity, lack of selectivity against cancer cells and extrusion by membrane transporters responsible for multidrug resistance (MDR) such as P-glycoprotein (P-gp). Recognizing the potential of new compounds to inhibit P-gp function and/or expression is essential in the search for effective anticancer drugs. Eleven Hsp90 inhibitors containing an isoxazolonaphtoquinone core were synthesized and evaluated in two MDR models comprised of sensitive and corresponding resistant cancer cells with P-gp overexpression (human non-small cell lung carcinoma and colorectal adenocarcinoma). We investigated the effect of Hsp90 inhibitors on cell growth inhibition, P-gp activity and P-gp expression. Structure-activity relationship analysis was performed in respect to cell growth and P-gp inhibition. Compounds 5, 7, and 9 directly interacted with P-gp and inhibited its ATPase activity. Their potential P-gp binding site was identified by molecular docking studies. In addition, these compounds downregulated P-gp expression in MDR colorectal carcinoma cells, showed good relative selectivity towards cancer cells, while compound 5 reversed resistance to doxorubicin and paclitaxel in concentration-dependent manner. Therefore, compounds 5, 7 and 9 could be promising candidates for treating cancers with P-gp overexpression.

    Abstract 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.
