Abstract P-glycoprotein (P-gp)-mediated multidrug resistance (MDR) is a major impediment for clinical cancer therapy. 19 novel aromatic amides with triazole-core as MDR reversal agents were designed and synthesized via click chemistry to reverse MDR. Among them, compound 42 was identified as the most promising candidate with high potency (EC50 = 78.1 ± 5.4 nM), low cytotoxity (SI > 1282) and persistent duration in reversing doxorubicin (DOX) resistance in K562/A02 cells. 42 also enhanced the potency of other P-gp associated cytotoxic agents with different structures. In further study, remar...

In this study, based on nucleolin’s active transport property to the nucleus and its affinity with aptamer, we developed a nuclear-targeted delivery system to circumvention of drug resistance in breast cancer (MCF-7/Adr). Dox·HCl inserted in the aptamer AS1411 (Ap-Dox) was encapsulated in the aqueous interior of liposome (Lip(Ap-Dox)). In vitro studies showed that after the Lip(Ap-Dox) diffusing into MCF-7/Adr cells, Ap-Dox complex bound with nucleolin strongly and eventually entered the cell nuclei. By using this drug delivery system, Dox·HCl can efficiently accumulated in the nuclei to effectively kill the cancer cells.

Development of high‑resolution melting analysis for ABCB1 promoter methylation: Clinical consequences in breast and ovarian carcinoma. Oncol Rep. 2019 Jun 05;: Authors: Vaclavikova R, Klajic J, Brynychova V, Elsnerova K, Alnaes GIG, Tost J, Kristensen VN, Rob L, Kodet R, Skapa P, Mrhalova M, Soucek P Abstract Multidrug resistance to anticancer drugs, which is often associated with enhanced expression of the ATP‑binding cassette (ABC) transporter P‑glycoprotein (encoded by the ABCB1 gene) may limit the effects of cancer therapy. Epigenetic regulation of ABCB1 expression may thus have a clinical im...

In this study, a RGD conjugated, pH sensitive lipid was synthesized using glycerin monostearate (GMS) and adipic acid dihydrazide (HZ) as lipid materials and named RGD-HZ-GMS. RGD-HZ-GMS was applied to encapsulate DOX to construct a RGD modified, DOX loaded SLNs (RGD-DOX-SLNs). To evaluate the anticancer effect of RGD-DOX-SLNs, breast cancer cell line (MCF-7 cells) and DOX resistant cell line (MCF-7/ADR cells) were used. in vivo tumor suspension and toxicity effects were evaluated on mice bearing MCF-7/ADR cells breast cancer model. RGD-DOX-SLNs had a uniformly spherical shape. The mean particle size and zeta potential of ...
